GRB-59 Discussion

6. The Chair of GRB proposed to transform the expert group on UN Regulation No. 51 into an informal working group (IWG) by preparing and adopting its Terms of Reference (ToR) which should focus on harmonizing the current proposal of 03 series of amendments to UN Regulation No. 51 with the provisions of the proposal of the Parliament and the Council of EU1, as well as including additional aspects concerning the Chinese and Japanese markets. To this end, a working document would be drafted by the IWG for consideration by GRB at its sixtieth session. The IWG should also address additional amendments by preparing an informal document for consideration by GRB at its sixtieth or sixty-first sessions. The experts from France, Germany, Netherlands and EC supported this initiative. It was suggested that ToR should also cover UN Regulation No. 59 (Replacement silencing systems). The experts from France, Germany, Japan, Netherlands, Spain, Switzerland, United Kingdom, EC, CLEPA, ETRTO and OICA announced their intention to participate to the work of the IWG. Finally, based on a draft prepared by the Expert Group, GRB adopted the ToR (GRB-59-10-Rev.1), of the IWG on UN Regulation No. 51 and UN Regulation No. 59, as reproduced in Annex II to this report, subject to WP.29 consent.

1The “Proposal for a Regulation of the European Parliament and of the Council on the sound level of motor vehicles” (2011/0409 (COD)) and related documents are available on the EC Enterprise web site: Reference documents – Legislative proposals: Sound level of motor vehicles. However, the last revision of this document was still in process as of this GRB session and not yet available to the public.

7. The expert from EC informed GRB about the work progress of the EU regulation on the noise emission and introduced a revised proposal for the 03 series of amendments to Regulation No. 51 submitted by the GRB Expert Group on UN Regulation 51 (GRB-59-04-Rev.1). He clarified that the proposal was based on GRB-58-17-Rev.1, outcome of the GRB expert group meeting and on the latest update of the EU regulation. He clarified that one of the major modifications introduced was the deletion of Annex 11 on the Audible Vehicle Alerting System (AVAS) which should become part of the UN GTR on Quiet Road Transport Vehicles (QRTV) and come into force in due course. The experts from EC and OICA pointed out the difficulties in aligning the texts of the draft EU regulation on the noise emission and UN Regulation No. 51, due to different definitions and legal languages used.

8. The experts from Germany, Japan, Netherlands, Switzerland, EC, ETRTO, OICA as well as the Chair addressed the issue whether or not to delete the footnote after the table with sound level limits in paragraph 6.2.2.1. of GRB-59-04-Rev.1 which refers to the last column “Phase 3” and reads as follows: “To be reviewed and confirmed or modified at the latest one year after entry”. GRB noted that this provision corresponds to Article 7 of the draft EU regulation on the noise emission and aims to review the appropriateness of the noise limits in the future. However, the legal implications of the footnote seemed unclear. GRB invited the expert from EC to clarify this issue with the EU legal services. In the meantime, GRB agreed to put the footnote in square brackets and resume consideration at a later stage. GRB also extensively discussed the wording of paragraph 6.2.2.1 (sound limit values and categories of vehicles) introducing exceptions for limit values applicable to certain categories of vehicles.

Go to session report

9. GRB resumed consideration of the limit values for certain vehicle categories on the basis of a presentation by the expert from Japan (GRB-59-09) on flat front light vehicles of category N1. The experts from France, Germany, Italy and OICA supported GRB-59-09. The expert from EC stated that a common EU position on this issue, as well as on M3 buses, was expected at the beginning of 2014.

10. Thus, GRB recalled GRB-58-08, GRB-58-09 and GRB-58-10 tabled by the expert from China in which he suggested higher limit values for vehicles of a specific category on the Chinese market. Referring to the above proposal by Japan, GRB invited the expert from China to explain and further justify his proposal in a similar way, possibly at the next sessions of the IWG on UN Regulation No. 51 and UN Regulation No. 59 in March and May 2014. GRB agreed to refer GRB-59-04-Rev.1 to the IWG incorporating all the changes agreed during the session, including GRB-59-09. GRB also agreed to resume discussion on the 03 series of amendments at its September 2014 session on the basis of an official proposal submitted by the IWG.

Go to session report

11. GRB adopted ECE/TRANS/WP.29/GRB/2014/2, not amended, tabled by the expert from OICA to update the requirements on the noise test track from ISO 19844:1994 (i.e. Annex 8 of this Regulation) to ISO 10844:2011, as well as to incorporate transitional provisions to allow repaving of existing, non-complying test tracks with the ISO 10844:2011 standards. The secretariat was requested to submit ECE/TRANS/WP.29/GRB/2014/2 to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1), for consideration and vote at their June 2014 sessions as draft Supplement 10 to the 02 series of amendments to Regulation No. 51.

Go to session report

12. GRB resumed discussions on ECE/TRANS/WP.29/GRB/2013/4 and GRB-57-13 proposing amendments to improve the test method of the 02 series of amendments to the UN Regulation, as well as an amendment to the acceleration test value proposed by the expert from China in GRB-58-07. GRB noted that the Chinese concerns had been taken into account by ISO Working Group 42 when revising Standard ISO 362-1:2007, referred in the current test method of the UN Regulation. The expert from China withdrew ECE/TRANS/WP.29/GRB/2013/4, GRB-57-13 and GRB-58-07 and announced a possible future proposal as a result of further exchange of views with ISO.

Working Party on Noise | Session 56 | 3-5 Sep 2012

2. GRB considered and adopted the agenda ECE/TRANS/WP.29/GRB/2012/4 and its Add.1 including new agenda items 15(a), 15(b), 17 and 18.

3. GRB noted ECE/TRANS/WP.29/GRB/2012/5, tabled by the expert from the Russian Federation, to provide harmonized definitions on vehicle type concerning noise, the terms noise and sound. The expert from IMMA expressed a reservation (GRB-56-08) on the proposal as a whole arguing that the introduction of new definitions would be premature, taking into account the recent publication of Revision 2 of UN Regulation No. 41. GRB agreed to resume consideration on this proposal at its February 2013 session on the basis of further information provided by the expert from the Russian Federation.

4. GRB considered GRB-56-04, introduced by the expert from ISO, updating the text concerning the test site of the UN Regulation with the latest amendment of ISO Standard 5130:2012. The proposal received comments from the expert by Germany who suggested more objective criteria in verifying the level of porosity of the test site. GRB agreed to resume consideration on this subject on the basis of a revised proposal voluntarily prepared by the expert from ISO.

5. The expert from IMMA sought GRB’s clarification on paragraph 8.2. on the conformity of production tests, specifically: whether the 1 dBA allowance was applicable to the maximum A-weighted sound pressure level representing urban driving (Lurban) and to the sound pressure level in wide open throttle (Lwot). GRB agreed that currently paragraph 6.2.3. (specification regarding sound levels) clearly stated that the difference between Lwot shall not exceed the limit value for Lurban by more than 5 dB and if the +1dB was applied to Lurban, as given in Annex 6, then this additional +1 dB allowance was automatically also applicable to Lwot value.

No report

6. See also, para. 20, concerning the updating of the requirements on the noise test track from ISO 10844:1994 to ISO 10844:2011, GRB agreed to defer discussion on ECE/TRANS/WP.29/GRB/2012/16 and ECE/TRANS/WP.29/GRB/2012/17 to its February 2013 session.

7. The expert from OICA introduced ECE/TRANS/WP.29/GRB/2012/8, consolidating a proposal of 03 series of amendments to UN Regulation No. 51. The proposal received comments from the expert of ETRTO (GRB-56-16) proposing to change the vehicle test conditions of Annex 10 of UN Regulation No. 51. GRB noted that the proposed changes (GRB-56-16) have already been adopted as Supplement 8 to the 02 series of amendments and agreed to amend ECE/TRANS/WP.29/GRB/2012/8 accordingly. Moreover, the expert from the Netherlands introduced GRB-56-12 proposing a new layout for the communication form. GRB agreed to resume consideration at its February 2013 session on ECE/TRANS/WP.29/GRB/2012/8 on the basis of a revised document prepared by the expert from the Netherlands in cooperation with the experts from CLEPA and OICA. GRB recommended experts to provide detailed comments.

8. GRB considered and adopted GRB-56-03 as reproduced in Annex II to this report, amending the figure for measuring positions of vehicles in motion. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2013 session as Supplement 9 to the 02 series of amendments to UN Regulation No. 51.

9. Finally GRB considered GRB-56-06, tabled by the expert from China, introducing amendments to the test method. He introduced GRB-56-09 for information, showing the difference among the test methods in UN Regulation No. 51, ISO 362 and the Chinese standard (GBI1495-2002) and GRB-56-22 as a justification to the proposed amendments to the test. The expert from OICA suggested that such relevant outcome of research should be brought together with those from other Contracting Parties to the 1958 Agreement (i.e. European Union) to keep UN Regulation No. 51 relevant worldwide. GRB agreed to resume discussion at the February 2013 session on a possible official proposal (based on GRB-56-06) tabled by the expert from China in cooperation with the expert from ISO.

10. The EC expert informed GRB on the work progress of the European Union (EU) institutions on the EC proposal on vehicle noise. He added that at this stage no political agreement on new limits had been reached at the EU level.

11. The expert from China introduced GRB-56-07, proposing a different scheme to identify vehicle categories. He also added that his proposal would offer an option to cover needs of a broader range of countries. The experts from Japan and OICA endorsed the Power to Mass Ratio index (PMR) as a tool to link noise emission and vehicle performance. The EC expert recalled that to overcome the different national political priorities/classifications, the discussion should be focused on the mutual recognition principle of the 1958 Agreement, i.e. the vehicle complying with the lowest noise level would be accepted everywhere. He recalled that this would not prevent Contracting Parties from having less stringent requirements in their national law for their internal markets. Finally GRB agreed to resume consideration of GRB-56-07 at its February 2013 session to provide study time for experts.

12. GRB considered GRB-56-01 and GRB-56-05 supplementing ECE/TRANS/WP.29/GRB/2012/7 tabled by the expert from Japan. He explained that the proposal was based on GRB-55-01, including limit values with some modification of the threshold of subcategories, as a basis for a common position with the proposal tabled by the expert from Germany (GRB-54-03). Moreover, he made a presentation (GRB-56-21) concerning rationales for the proposed Stage 3 of limit values. The EC expert stated that the review of vehicle classification should not only consider the proposals tabled by the experts from Germany and Japan, but also the present vehicle classification in UN Regulation No. 51 and in the EC proposal and verify the rationales for the changes proposed by the experts from Germany and Japan.

GRB recalled that the EC proposal was available at: http://ec.europa.eu/enterprise/sectors/automotive/documents/proposals/index_en.htm#h2-1

13. Upon the suggestion of the Chair, GRB agreed to verify data and provide a basis for analysis for a power reference value of 160 kW in vehicle category M3 and for the reference value of 140 kW in vehicle category N2. Finally, GRB agreed to resume consideration on this subject at its February 2013 session on the basis of the above test data, if available, and on those existing provided by the experts from China, Japan and EC.

14. GRB noted that no new information had been given under this agenda item.

15. The expert from CLEPA introduced GRB-56-17 listing further test results of four vehicles performed by his organization on additional sound emission provisions (ASEP) of replacement silencing systems. GRB noted that as an outcome of the test, two possible alternatives were possible to introduce ASEP provisions into UN Regulation No. 59: (i) the test should be carried out back to back to the original equipment and replacement system (ii) the manufacturer of the replacement system should perform the test with the same acceptance criteria as for the original equipment. GRB, in principle, agreed to follow option (ii) and to resume consideration on this subject at its February 2013 session on the basis of a concrete proposal tabled by the expert from CLEPA.

16. GRB noted that no new information had been given under this agenda item.

17. Referring to the report of the Working Party on Brakes and Running Gear (GRRF) (see ECE/TRANS/WP.29/GRRF/72, paras. 25 and 32-34), GRB considered ECE/TRANS/WP.29/2012/54 and ECE/TRANS/WP.29/2011/55, proposing to add specific performance requirements for C2 snow tyres and amending the definition of the measuring rim for C1, C2 and C3 tyres. GRB endorsed ECE/TRANS/WP.29/2012/55 without amendment, scheduled to be considered by WP.29 and AC.1 at their November 2012 sessions. Concerning ECE/TRANS/WP.29/2012/54, GRB considered GRB-56-15 tabled by the expert from Germany, proposing to introduce the inscription “M+S” or “M.S” or “M&S” only in combination with the “Alpine” symbol on a mandatory basis, if the tyre be classified as a “snow tyre for use in severe snow conditions”. Accordingly, GRB endorsed ECE/TRANS/WP.29/2012/54, as amended by Annex III to this report and agreed to submit it to WP.29 and AC.1, for consideration at their November 2012 sessions as draft Supplement 2 to the 02 series of amendments, subject to a final review by GRRF at its September 2012 session.

18. The expert from ETRTO introduced ECE/TRANS/WP.29/GRB/2012/10 aligning the text of Annex 6 of the UN Regulation to ISO Standard 28580. GRB adopted the proposal not amended and agreed to submit it to WP.29 and AC.1, for consideration at their March 2013 session as draft Supplement 3 to the 02 series of amendments to UN Regulation No. 117, also subject to a final review by GRRF at its September 2012 session (see ECE/TRANS/WP.29/GRRF/2012/18).

19. The expert from ETRTO proposed to amend the snow test method for C3 tyres (ECE/TRANS/WP.29/GRB/2012/11). However, GRB argued that some of the proposed amendments could conflict with the recommended introduction of blocking differential on driven axle as increasing repeatability in the test. GRB agreed to resume consideration of the proposal at its next session on the basis of an official document submitted to the March 2013 sessions of WP.29 and AC.1, incorporating possible changes (see ECE/TRANS/WP.29/GRRF/2012/19) agreed by GRRF at its September 2012 session.

20. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRB/2012/15 and ECE/TRANS/WP.29/GRB/2012/18 updating the test track provisions to ISO 10844:2011. The expert from ETRTO introduced similar amendments (ECE/TRANS/WP.29/GRB/2012/9) but without transitional provisions. GRB agreed that the introduction of new provisions for the test track should refer to a new series of amendments of the UN Regulation. Following the suggestion of the Chair and Vice-Chair, GRB considered GRB-56-20 (superseding ECE/TRANS/WP.29/GRB/2012/15, ECE/TRANS/WP.29/GRB/2012/18 and ECE/TRANS/WP.29/GRB/2012/9) drafted in accordance with ECE/TRANS/WP.29/1044/Rev.1 “Guidelines on the scope, administrative provisions and alternative requirements in Regulations annexed to the 1958 Agreement”. GRB requested the secretariat to distribute GRB-56-20 with an official symbol at its February 2013 session and agreed to refer to it as a basis to continue discussion on this subject.

21. Finally, GRB considered GRB-56-02 tabled by the expert from the Russian Federation aimed at providing detailed elaboration of the concept of tyre deceleration (dω/dt) in the test technology. The secretariat was requested to distribute it with an official symbol at its February 2013 session, pending the clarification of the reference to the “deceleration calculator” mentioned in the proposal.

No report

22. GRB noted that no new information had been given under this agenda item.

23. The expert from IMMA introduced ECE/TRANS/WP.29/GRB/2012/13 and ECE/TRANS/WP.29/GRB/2012/14 respectively amended by GRB-56-10 and GRB-56-11. He clarified that both proposals were aimed at introducing into UN Regulations Nos. 9 and 63 new requirements for improved noise control of motorcycles and anti-tampering measures, but not yet ASEP provisions. GRB adopted ECE/TRANS/WP.29/GRB/2012/13 and ECE/TRANS/WP.29/GRB/2012/14 as amended by Annex IV to this report. The secretariat was requested to submit them to WP.29 and AC.1 for consideration at their March 2013 sessions: ECE/TRANS/WP.29/GRB/2012/13 as draft 07 series of amendments to UN Regulation No. 9 and ECE/TRANS/WP.29/GRB/2012/14 as draft 02 series of amendments to UN Regulation No. 63.

24. The expert from Japan introduced GRB-56-18 providing an overview of the current framework of vehicle noise regulation in his country. Upon the suggestion of the GRB Chair, it was agreed to continue an exchange of information on the basis of data concerning noise values declared by manufacturers for each different tyre classes.

25. The expert from ETRTO gave a presentation (GRB-56-14), on a holistic approach for rolling noise mitigation. For an efficient decrease of rolling noise he underlined the need to take into account road construction. GRB invited the expert from ETRTO to develop studies on this subject and to inform experts at further sessions.

26. The expert from EC, secretary of the informal working group on Quiet Road Transport Vehicles (QRTV), reported on the outcome of the first meeting of the group held on 18-20 July 2012 in Washington D.C., United States of America (USA). He added that the next meeting of the group was planned for the beginning of December 2012. GRB noted that the publication of the New Proposal of Rule Making (NPRM) to which the development of the UN GTR on QRTV was linked, was not yet publicly available in the United States of America. Finally, the GRB Chair invited all experts to provide comments to the NPRM as soon as it was be published.

27. The expert from OICA introduced GRB-56-13, providing an overview of the current definitions in UN Regulations under the responsibilities of GRB. However, GRB agreed to resume discussion at its February 2013 session on the basis of informal documents listing all acronyms associated to the UN Regulations concerned. Accordingly, GRB agreed to follow the layout of GRSP-51-03, considered during the May 2012 session of the Working Party on Passive Safety (GRSP), designed for this purpose. Finally, it was agreed that the informal documents would list the acronyms of: (i) UN Regulation No. 51 by the expert from OICA, (ii) UN Regulations Nos. 59 and 28 by the expert from CLEPA and (iii) UN Regulation Nos. 9, 41, 63 and 92 by the expert from IMMA for consideration at the next session of GRB.

28. The expert from the Russian Federation introduced ECE/TRANS/WP.29/GRB/2012/12 aimed at revising the Consolidated Resolution on the Construction of Vehicles (R.E.3). GRB decided to resume discussion on this subject at its February 2013 session, awaiting revised proposals tabled by the expert from the Russian Federation and reproducing the different subjects proposed by ECE/TRANS/WP.29/GRB/2012/12 (e.g. interior noise level). In the meantime, it was requested that the experts from ISO and OICA provide their comments on ECE/TRANS/WP.29/GRB/2012/12 to the expert from the Russian Federation to finalize the revised proposals.

29. The Chair informed GRB that the next Environmental Friendly Vehicle conference (EFV) would be held in Baltimore, USA, from 10 to 12 September 2012. GRB would be updated on the outcome accordingly, in February 2013.

30. GRB considered document WP.29-156-21-Rev.1 and nominated the delegation of the European Commission to ensure the task of Ambassador for GRB on IWVTA activities of WP.29.

No report

33. In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and Amend.1), GRB elected its officer on Tuesday afternoon. Mr. S. Ficheux (France) was unanimously elected Chair of GRB for the sessions scheduled in 2013.

1. The Working Party on Noise (GRB) held its fifty-sixth session from 3 (afternoon) to 5 (afternoon) September 2012 in Geneva. The meeting was chaired by Mr. Ch. Theis (Germany). Experts from the following countries participated in the work following Rule 1(a) of the Rules of Procedure of the World Forum for Harmonization of Vehicle Regulations (WP.29) (TRANS/WP.29/690 and Amend.1): Belgium; Brazil; Czech Republic; China; France; Germany; Hungary; India; Italy; Japan; Netherlands; Norway; Poland; Republic of Korea; Russian Federation; Serbia; South Africa; Spain; Sweden; Switzerland; United Kingdom of Great Britain and Northern Ireland. Experts from the European Commission (EC) participated. Experts from the following non-governmental organizations also participated: European Association of Automobile Suppliers (CLEPA); International Motorcycle Manufacturers Association (IMMA); International Organization for Standardization (ISO); International Organization of Motor Vehicle Manufacturers (OICA). Upon the special invitation of the Chair, experts from the following non-governmental organization participated: European Tyre and Rim Technical Organisation (ETRTO).

31. Referring to the request of WP.29 agreed at its June 2012 session (see ECE/TRANS/WP.29/1097, para. 14), GRB considered a proposal (WP.29-157-06) on design/control principles of Advanced Driver Assistance Systems to harmonize minimum guidelines tabled by the informal working group on Intelligent Transport Systems (ITS) and adopted it without comments.

32. GRB noted the request of WP.29 at its June 2012 session (see ECE/TRANS/WP.29/1097 para. 12) to its representatives and experts to use the template contained in WP.29-157-07-Rev.1 when preparing official documents for the World Forum and its subsidiary bodies.

34. Learning that Mr. C. Theis would no longer participate in future sessions of GRB, the group acknowledged his valuable contribution to the work of GRB and wished him all the best in his future activities.

35. For its fifty-seventh session, scheduled to be held in Geneva from 5 (starting at 2.30 p.m.) to 7 (concluding at 5.30 p.m.) February 2013, GRB noted that the deadline for submission of official documents to the secretariat was 9 November 2012, twelve weeks prior to the session. Moreover, the following provisional agenda was adopted:

No report

21. GRB noted that no new information had been given under this agenda item.

27. The expert from EC, secretary of the informal working group on Quiet Road Transport Vehicles (QRTV), introduced the status report of the second meeting of QRTV (GRB-57-29) and announced that the Notice of Proposed of Rulemaking (NPRM) of the United States of America (US) on minimum sound requirements for hybrid and electric vehicles was published on 9 January 2013, including a draft environmental assessment study. He informed GRB that the next meeting of QRTV would be held from 16 to 18 April 2013 in Brussels. He also introduced GRB-57-15 to propose the development of a “sound emission profiling test” for QRTV to match safety and environmental needs and support the positive impact on traffic noise introduced by the deployment of Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs). He invited GRB experts to assess the feasibility of this proposal in which the main objective would be the profiling of vehicle noise up to a speed of 30 km/h.

28. The Chair of GRB underlined the opportunity given by the publication of the NPRM to provide the US authorities with comments by GRB. The expert from the Netherlands expressed concerns on how the audible vehicle alerting system (AVAS) installed on QRTV could negatively affect the environment. He also expressed concerns on how the installation of such devices would probably shift the responsibility of the driver to vulnerable road users such as visually impaired people. As a general comment to the NPRM, GRB agreed that the development of the UN Global Technical Regulation on QRTV (that would also be based on the NPRM and on ECE/TRANS/WP.29/GRB/2012/6), should be environmentally friendly and coherent with vehicle noise levels worldwide including ASEP provisions. Finally, the Chair of GRB invited all experts to provide comments on the NPRM directly to the National Highway Traffic Safety Administration (NHTSA). GRB agreed to resume discussion at its September 2013 session on the basis of the outcome of the informal working group.

No report

34. GRB noted that no new information had been given under this agenda item.

35. The expert from EC introduced GRB-57-24, showing the need to candidate UN Regulations, under the responsibility of GRB, applicable to IWVTA. GRB agreed to candidate UN Regulations Nos. 28 and 51 excluding UN Regulation No. 117 in view of possibly developing a UN Regulation by GRRF covering the installation of tyres on vehicles.

No report

38. For its fifty-eighth session, scheduled to be held in Geneva from 2 (starting at 2.30 p.m.) to 4 (concluding at 5.30 p.m.) September 2013, GRB noted that the deadline for submission of official documents to the secretariat was 7 June 2013, twelve weeks prior to the session. Moreover, the following provisional agenda was adopted:

1. Adoption of the agenda.

36. The expert from OICA introduced GRB-57-04 (amending WP.29-157-06) on design/control principles of Advanced Driver Assistance Systems to harmonize minimum guidelines tabled by the informal working group on Intelligent Transport Systems (ITS). GRB invited all experts to provide their comments to the expert from OICA by the end of February 2013.

23. The expert from EC introduced GRB-57-14, fostering the development of ASEP provisions for UN Regulations Nos. 9, 63 and 92. He added that his requested was motivated by the upcoming development of EU legislation on vehicle category L. GRB agreed to resume consideration on this agenda item on the basis of a proposed road map to cover this issue tabled by the expert from IMMA. In the meantime, experts were invited to send their comments to the expert from IMMA as support in the development of this proposal.

1. The Working Party on Noise (GRB) held its fifty-seventh session from 5 (afternoon) to 7 (afternoon) February 2013 in Geneva. The meeting was chaired by Mr. S. Ficheux (France). Experts from the following countries participated in the work following Rule 1(a) of the Rules of Procedure of the World Forum for Harmonization of Vehicle Regulations (WP.29) (TRANS/WP.29/690, Amend.1 and Amend.2): Belgium; Czech Republic; China; France; Germany; India; Italy; Japan; Netherlands; Norway; Poland; Russian Federation; Serbia; South Africa; Spain; Sweden; Switzerland; United Kingdom of Great Britain and Northern Ireland. Experts from the European Commission (EC) participated. Experts from the following non-governmental organizations also participated: European Association of Automobile Suppliers (CLEPA); International Motorcycle Manufacturers Association (IMMA); International Organization for Standardization (ISO); International Organization of Motor Vehicle Manufacturers (OICA). Upon the special invitation of the Chair, experts from the following non-governmental organization participated: European Tyre and Rim Technical Organisation (ETRTO).

3. GRB resumed discussion on ECE/TRANS/WP.29/GRB/2012/5, tabled by the expert from the Russian Federation, providing harmonizing definitions on vehicle type concerning noise, the terms noise and sound. The expert from the Russian Federation introduced comments (GRB-57-21) to the concerns raised by the expert from IMMA to his proposal during the September 2012 session of GRB. The expert from IMMA recalled his reservation (GRB-56-08) to ECE/TRANS/WP.29/GRB/2012/5 and announced the provisions of further information for the September 2013 session of GRB. Accordingly, GRB agreed to resume discussion on this proposal at its next session on the basis of detailed information provided by the experts concerned.

4. GRB also resumed discussion on GRB-56-04, tabled by the expert from ISO, updating the text of the UN Regulation concerning the test site with the latest amendment of ISO Standard 5130:2012. The expert from ISO announced that the objectivity of the criteria in verifying the level of porosity of the test site had been clarified with expert from Germany and that a revised proposal was not needed. GRB agreed to resume consideration on this subject at its next session and requested the secretariat to distribute GRB-56-04 with an official symbol.

5. Concerning the updating of the requirements on the noise test track from ISO 10844:1994 to ISO 10844:2011, GRB agreed on aligning the UN Regulation with the decision taken for UN Regulation No. 117 on this subject (superseding ECE/TRANS/WP.29/GRB/2012/16) (see also paras. 16 and 17). Accordingly, the expert from OICA withdrew GRB-57-20 and it was agreed to keep ECE/TRANS/WP.29/GRB/2012/16 for reference. Finally, GRB agreed to defer discussion at its September 2013 session on the basis of a revised consolidated proposal of 03 series of amendments to the UN Regulation (ECE/TRANS/WP.29/GRB/2012/8) including a new proposal for transitional provisions (GRB-57-17), ECE/TRANS/WP.29/GRB/2012/17 and the provisions of Supplement 8 to the 02 series of amendments (see para. 10).

6. The expert from China introduced ECE/TRANS/WP.29/GRB/2013/4 and GRB-57-13 proposing amendments to improve the test method of the 02 series of amendments to the UN Regulation. The expert from OICA questioned the opportunity of introducing amendments to the 02 series of amendments, taking into account that the latter one would be superseded in a short time by the 03 series of amendments. He finally proposed that draft amendments of method B, concerning Annexes 9 and 10 of the UN Regulation introduced by ECE/TRANS/P29/GRB/2013/4, would be discussed at the next ISO Working Group 42 meeting in April, because affecting the measurement procedure of method B reproduced in Standard ISO 362-1:2007. The expert from ISO agreed on this approach. GRB agreed to resume discussion on this subject at its September 2013 session on the basis of a proposal jointly revised by the experts from China, ISO and OICA.

7. GRB resumed consideration on vehicle categories and their limit values on the basis of an existing database in China, Japan and EC. The expert from Japan introduced again GRB-56-05 and then GRB-57-22 explaining that according to the monitoring database in his country, the best fitting threshold for vehicle categories N2 and M3particularly should be 135 kW of power mass ratio (PMR). He continued that this value would encompass properly downsized vehicles that have a high impact on noise emissions from the vehicle fleets in Asian countries. He urged finding a compromise on vehicle categories and the adoption of a concrete proposal of the 03 series of amendments to the UN Regulation (i.e. ECE/TRANS/WP.29/GRB/2012/7). He stated that the introduction of additional sound emission provisions (ASEP) was much awaited in Japan. The expert from China gave two presentations (GRB-57-05 and GRB-57-06), to introduce possible compromise solutions (GRB-57-07) focusing on design characteristics as well as on PMR. The expert from OICA expressed appreciation for the efforts made by the expert from China to find convergence on the vehicle classification and introduced a possible compromise solution (GRB-57-19). The expert from Germany recalled that GRB started discussion with the agreement of developing a proposal for amendments focused on performance criteria rather than on design requirements. Moreover, he added that the allowance of 1 dBA for vehicles with direct injection diesel engines no longer justified. Finally, he recommended simplifying classes and subclasses, to avoid cumbersome vehicle classification thresholds that could hamper technical progress.

8. The EC expert informed GRB through a presentation (GRB-57-28) on the work progress of the European Union (EU) institutions on the EC proposal on vehicle noise. He showed that the European Parliament, at its plenary session, improved the EC proposal with the possibility of rounding the noise measurement values and using lower test acceleration (2 m/s2). He announced a further update for the September 2013 session of GRB and invited other Contracting Parties to provide information on the implementation of new noise limits at their national/regional level.

9. The expert from Switzerland introduced an analysis of the Swiss database based on vehicle noise tests (GRB-57-23) conducted in conformity to the 02 series of amendments to the UN Regulation and on limit values proposed by the experts from Germany, Japan and EC. GRB agreed to resume discussion on this subject at its September 2013 session and recommended experts to provide detailed comments.

10. GRB agreed to establish a group of interested experts on vehicle noise, led by the expert from EC, with the main goal of (i) finalizing a common proposal on vehicle classification (including subcategories) and (ii) update a proposal of 03 series of amendments to UN Regulation No. 51 aiming at maintaining consistency with the EU legislation proposal. The schedule of the first meeting of the group was agreed for 19 April 2013, tentatively in Brussels. Finally, GRB agreed to keep as reference in the agenda of the next session informal documents GRB-54-03, GRB-57-07, GRB-57-19 and GRB-57-23 and to resume discussion on the basis of the outcome of the meeting of the group of interested experts.

11. GRB noted that no new information had been given under this agenda item.

12. The expert from CLEPA introduced a proposal (GRB-57-27) for amendments to the UN Regulation aimed at introducing ASEP provisions. GRB agreed to defer discussion on this subject to its September 2013 session and requested the secretariat to distribute GRB-57-27 with an official symbol at that session.

13. GRB noted that no new information had been given under this agenda item.

14. GRB considered ECE/TRANS/WP.29/GRRF/2013/9 for the next session of the Working Party on Brakes and Running Gear (GRRF). The document proposes wet grip provisions and testing procedures for tyres of categories C2 and C3. GRB endorsed ECE/TRANS/WP.29/GRRF/2013/9 without amendments.

15. GRB resumed discussion on ECE/TRANS/WP.29/GRB/2012/11, amended by GRB-57-03. The expert from EC expressed reservation on the term of differential lock that could lead to misconception. GRB endorsed the reservation of the expert from EC and agreed to inform GRRF.

16. The expert from ETRTO introduced ECE/TRANS/WP.29/GRB/2013/5, drafted in cooperation with the experts from Poland and the United Kingdom, proposing to update the test track requirements to ISO 10844:2011 as a supplement to the UN Regulation rather than a new series of amendments. He stated that the new test track with tighter tolerances would maintain the same nominal noise behaviour and that its introduction as a new series of amendments was not justified (GRB-57-02). The experts from France endorsed the proposal and stated that technical variations introduced by the new track would not justify a new series of amendments. The experts from Italy and Japan also endorsed ECE/TRANS/WP.29/GRB/2013/5.

17. GRB finally adopted ECE/TRANS/WP.29/GRB/2013/5 (superseding ECE/TRANS/WP.29/GRB/2013/2, ECE/TRANS/WP.29/GRB/2012/15 and ECE/TRANS/WP.29/GRB/2012/18) as reproduced in Annex II to this report. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration and vote at their June 2013 sessions as draft Supplement 4 to the 07 series of amendments to UN Regulation No. 117. Moreover, GRB agreed that extensions of type approvals, granted by using the test track in accordance to ISO 10844:1994, may be carried out with the test track built in accordance with ISO 10844:2011, taking into account that this last would not negatively affect type approval noise test results.

18. The expert from the Russian Federation introduced ECE/TRANS/WP.29/GRB/2013/3, amended by GRB-57-01, proposing the use of a “Deceleration Calculator” software for the deceleration test method in the test procedure for measuring rolling resistance. He informed GRB about the variant of data processing in the rolling resistance deceleration test method basing on the dω/dt formula. He underlined that this variant was used as an alternative to the existing data processing stipulated in UN Regulation No. 117, not affecting the existing test methods, and that it fully matches ISO 28580 and the procedures of Annex 6 of UN Regulation No. 117. The “Deceleration calculator” is a mathematical tool providing high accuracy [σ < 0.001%; R2 > 0.999] of development in the experimental data. The concept dω/dt was incorporated into standard GOST R 52102.1 He also introduced GRB-57-25 to provide a background history on the development of legislation on rolling resistance and made a practical demonstration of the proposed “Calculator”.

19. GRB recommended that experts start using the proposed calculator and to provide comments at its September 2013 session. The expert from the Russian Federation was recommended to provide, in the meantime, further background information on the algorithms of the calculator and on both proposals (ECE/TRANS/WP.29/GRB/2013/3 and GRB-57-01), as well as demonstration at the next session of GRRF for an exchange of views.

20. Concerning the concept of a new tyre contained in the scope of the UN Regulation, the expert from ETRTO stated that “a new tyre means a tyre which has been never used nor subjected to retreading operation and arriving directly from the production process”. GRB endorsed this concept.

22. GRB noted that no new information had been given under this agenda item.

24. The expert from OICA introduced GRB-57-16, proposing the concept of extension and revision of approvals into UN Regulations Nos. 28, 51, 59 and 117. As suggested by the Chair of GRB, it was agreed to list this item on the agenda of the Administrative Committee for the Coordination of Work of WP.29 (WP.29/AC.2) at its March 2013 session, due to its implication for the entire range of UN Regulations annexed to the 1958 Agreement. Finally, GRB agreed to resume discussion on this subject at its September 2013 session and invited its experts to provide comments to the expert from OICA in time to prepare an official proposal for that session.

25. GRB noted that no new information had been given under this agenda item.

26. The expert from EC informed GRB that the European Parliament had called for efforts on optimizing road surfaces to reduce noise and on introducing noise labels for the roads and vehicles, similar to the tyre label. He announced further information on this subject at the September 2013 session of GRB.

29. The experts from IMMA and OICA introduced GRB-57-12 and GRB-57-18, listing the current acronyms and abbreviation in UN Regulations under the responsibilities of GRB. GRB agreed to resume discussion at its September 2013 session on the basis of informal documents provided by the expert from CLEPA concerning UN Regulations Nos. 59 and 28, and by the expert from EC concerning QRTV.

30. The expert from the Russian Federation gave a presentation (GRB-57-26) to introduce revised proposals (GRB-57-08, GRB-57-09, GRB-57-10 and GRB-57-11) superseding ECE/TRANS/WP.29/GRB/2012/12. The expert from OICA raised a study reservation on GRB-57-08, aimed at specifying how to test road tractors with or without semitrailers and to refer them to the off-road category of vehicle. GRB agreed to resume discussion on this subject on the basis of a revised proposal tabled by the Russian expert from Russia in cooperation with the experts from France and OICA.

37. Learning that Mr. R. Falk (United Kingdom) and Mr. B. Kortbeek (The Netherlands) would no longer participate in future sessions of GRB, the group acknowledged their valuable contribution to the work of GRB and wished them all the best in their future activities.

Working Party on Noise | Session 58 | 2-4 Sep 2013

1. The Working Party on Noise (GRB) held its fifty-eighth session from 2 (afternoon) to 4 (afternoon) September 2013 in Geneva. The meeting was chaired by Mr. S. Ficheux (France). Experts from the following countries participated in the work following Rule 1(a) of the Rules of Procedure of the World Forum for Harmonization of Vehicle Regulations (WP.29) (TRANS/WP.29/690, Amend.1 and Amend.2): Belgium; Czech Republic; China; France; Germany; Hungary; India; Italy; Japan; Latvia; Netherlands; Norway; Republic of Korea; Russian Federation; Spain; Switzerland; United Kingdom of Great Britain and Northern Ireland. Experts from the European Commission (EC) participated. Experts from the following non-governmental organizations also participated: European Association of Automobile Suppliers (CLEPA); European Tyre and Rim Technical Organisation (ETRTO); International Motorcycle Manufacturers Association (IMMA); International Organization for Standardization (ISO); International Organization of Motor Vehicle Manufacturers (OICA) and World Blind Union (WBU).

2. GRB considered and adopted the agenda ECE/TRANS/WP.29/GRB/2013/6 and its Corr.1 and Add.1 including new agenda items 17 “Real release of particulates by transport vehicles”, 18 “Election of officers” and 19 “Provisional agenda for the fifty-ninth session”.

3. GRB adopted ECE/TRANS/WP.29/GRB/2013/11 not amended, introducing corrections to the current text of the UN Regulation. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration and vote at their March 2014 sessions as draft Supplement 1 to the 04 series of amendments to UN Regulation No. 41.

4. GRB also resumed discussion on a proposal (ECE/TRANS/WP.29/GRB/2013/7), tabled by the expert from ISO, updating the text of the UN Regulation and concerning the test site with the latest amendment of ISO Standard 5130:2012. GRB adopted ECE/TRANS/WP.29/GRB/2013/7 not amended. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration and vote at their March 2014 sessions as part of (see para. 3) draft Supplement 1 to the 04 series of amendments to UN Regulation No. 41.

5. The expert from IMMA introduced GRB-58-01, proposing an amendment to the transitional provisions of the UN Regulation. In the meantime GRB also considered GRB-58-11-Rev.1, aligning GRB-58-01 to the General Guidelines for UN Regulatory Procedures and Transitional Provisions in UN Regulations (ECE/TRANS/WP.29/1044/Rev.1). Finally, GRB adopted GRB-58-01, as reproduced in Annex II to this report. The secretariat was requested to submit GRB-58-01 to WP.29 and AC.1 for consideration and vote at their March 2014 sessions as part of (see paras. 3 and 4) draft Supplement 1 to the 04 series of amendments to UN Regulation No. 41. Moreover, GRB agreed to keep GRB-58-11-Rev.1 as a reference in its agenda of the January 2014 session, awaiting a possible proposal of full revision of the transitional provisions of the UN Regulation.

6. GRB resumed consideration of ECE/TRANS/WP.29/GRB/2012/5, tabled by the expert from the Russian Federation. The expert from IMMA reiterated the same concerns expressed in the last sessions of GRB (GRB-56-08), suggesting a time reservation on the proposal so as to receive more data from the technical services applying the 04 series of amendments of the UN Regulation recently entered into force. GRB agreed to resume discussion on this subject at its January 2014 session, awaiting possible proposals on harmonized definitions and terminology common to UN Regulations Nos. 9, 41, 63 and 92.

7. The expert from OICA, secretary of the group of interested expert on vehicle noise, introduced GRB-58-04 (superseding ECE/TRANS/WP.29/GRB/2012/8, ECE/TRANS/WP.29/GRB/2012/16 and GRB-56-12) as a result of discussions in the last meeting of his group held in Brussels on 4 July 2013. The expert from EC, Chair, of the same group clarified that GRB-58-04 was an attempt to merge the provisions of the proposal of the Parliament and the Council of the EU1 with the current proposal of 03 series of amendments to UN Regulation No. 51 and including additional aspects concerning the Chinese and Japanese markets, which were beyond the scope of the European Union legislation. He added that the outcome of discussions that would follow within GRB would be transmitted to the EU legislators with the aim of harmonizing the proposal with the draft 03 series of amendments. The expert from Japan proposed GRB-58-15 proposing the removal from GRB-58-04 of specifications on audible vehicle alerting system (AVAS) which is still in the process of development in the framework of activities of the UN GTR on Quiet Road Transport Vehicles (QRTV). The expert from Japan, Vice-Chair of the QRTV informal working group (IWG), also on behalf of the Chair of the IWG, reported similar concerns and request. The experts from China, the Republic of Korea and OICA supported these remarks. GRB endorsed the proposal made by the expert from Japan by suspending the discussion on AVAS provisions. GRB agreed to incorporate the results of discussion, including those of agenda item 3(b) (see paras. 10 and 11) into GRB-58-17-Rev.1., superseding GRB-58-04. It was noted that provisions still pending or suspended, were placed in square brackets in this document. The Chair of GRB clarified that GRB-58-17-Rev.1 would remain, on an informal basis, as a platform of discussion between the experts from GRB and EU in the group of interested experts on vehicle noise. GRB agreed to resume discussion on this subject on the basis of the outcome of next meetings of the group of interested experts scheduled for the first week of November 2013 and for the second week of January 2014 (both in Brussels).

8. Concerning the current 02 series of amendments to the UN regulation, GRB considered GRB-58-03, tabled by the expert from OICA updating the requirements on the noise test track from ISO 10844:1994 to ISO 10844:2011. GRB requested the secretariat to distribute GRB-58-03 with an official symbol at its next session.

9. Finally GRB resumed discussion on ECE/TRANS/WP.29/GRB/2013/4 and GRB-57-13 proposing amendments to improve the test method of the 02 series of amendments to the UN Regulation. Moreover, the expert from China introduced GRB-58-07, to propose an amendment to the acceleration test value. GRB agreed to postpone decision on these proposals until its January 2014 session, awaiting the outcome of the ongoing discussion in ISO Working Group 42 on revising Standard ISO 362-1:2007, referred in the current test method of the UN Regulation.

10. GRB resumed consideration on vehicle categories and their limit values on the basis of the proposal drafted by the group of interested experts (GRB-58-04). The expert from Japan gave a presentation (GRB-58-14) on light vehicles of category N1. Accordingly, he introduced GRB-58-06-Rev.1 amending GRB-58-04. The experts from France and Germany supported the proposal (GRB-58-06-Rev.1), which was incorporated into GRB-58-17-Rev.1 after the discussion. The expert from China partially supported the proposal from Japan. However, he showed in GRB-58-10 that the position of the engine is more relevant for vehicle categories M1 and N1 with a GVW ≤ 2.5 t, with the engine on the front axle and a rear axle drive. He underlined that these kinds of vehicles for these technical reasons produce a higher noise emission and suggested higher limit values (GRB-58-08). He also urged the need of vehicles categorization through their GVW instead of power mass ratio (GRB-58-09), aiming at provisions encompassing vehicle fleets at global level. The expert from France suggested clarifying the correspondence of the proposed vehicle classifications tabled by the expert from China and those proposed in GRB-58-04. The expert from the Netherland expressed concern that the proposals prepared by the expert from China could introduce design restrictions. The expert from Germany proposed further study in the framework of the interested group of experts on the basis of more data provided by the expert from China. He also suggested a three steps approach in finding a common agreement on: (i) vehicle category and subcategory, (ii) measurement method and finally on (iii) limits that eventually could match different scenarios.

11. GRB reproduced the whole discussion on the draft 03 series of amendments in GRB-58-17-Rev.1 as a basis of discussion of the informal group of experts and agreed to resume consideration on this subject at its January 2014 session (see para. 7 above). GRB also agreed to simplify the agenda of the next session by keeping as reference only GRB-58-08, GRB-58-09, GRB-58-10, GRB-58-14 and GRB-58-17-Rev.1.

12. GRB noted that no new information had been given under this agenda item.

13. The expert from CLEPA introduced ECE/TRANS/WP.29/GRB/2013/8 amended by GRB-58-05 and aimed at introducing ASEP provisions. The expert from the Russian Federation suggested that the text of the proposal should be aligned with the corresponding ASEP provisions of the 03 series of amendments to UN Regulation No. 51. GRB agreed to defer discussion on this subject to its January 2013 session awaiting a new official proposal at that session, aligned to a revised proposal on ASEP provisions of UN Regulation No. 51. It was also agreed to keep ECE/TRANS/WP.29/GRB/2013/8 and GRB-58-05 as references in the agenda of the next meeting.

14. GRB noted that no new information had been given under this agenda item.

15. The expert from the Russian Federation made a presentation (GRB-58-12) to introduce a revised proposal (ECE/TRANS/WP.29/GRB/2013/10) that would introduce a “Deceleration Calculator” software for the deceleration test method in the test procedure for measuring rolling resistance. The expert from France informed GRB that the proposed calculator had been verified for a first cycle of tests by the Technical Union for the Automobile, Motorcycle and Cycle Industries (UTAC). However, he added that the method should be still thoroughly analysed. The expert from ETRTO expressed some doubts on the variability of the method by temperature change and stated that further work was needed to demonstrate equivalence. The expert from the Russian Federation recalled that full cooperation was offered by the Russian experts as well as data sharing and asked GRB to take into consideration the positive experience developed by the industrial sector of his country in this field. The expert from France proposed to host a meeting of experts (date to be defined) in UTAC to further the exchange of views and finalize the proposal. The Chair of GRB suggested that other laboratories would start similar activities to evaluate the proposed method and devise possible alternative calculators to provide wider choice to future users. Finally, GRB endorsed the ad hoc meeting with the experts of ETRTO and the Russian Federation which was proposed by the expert from France to test the proposed “Deceleration Calculator”. It was also noted that once that the calculator was accepted by GRB as a valid alternative to the current one, it could be hosted on the WP.29 website, as an example, with an anonymous reference.

16. The expert from ETRTO introduced GRB-58-02, proposing new time measurement accuracy for instrumentation involved in the rolling resistance method (Annex 6 of the UN Regulation). The expert from the Russian Federation introduced GRB-58-13, arguing that this change of accuracy was not needed for Annex 6. GRB agreed to resume discussion on this subject at its January 2014 session, awaiting a revised proposal jointly prepared by the experts from the Russian Federation and ETRTO.

17. GRB noted the absence of new information under this item and agreed to remove it from the agenda of the next session.

18. GRB noted the absence of new information under this item and agreed to remove it from the agenda of the next session.

19. The expert from EC informed GRB that his organization was not favourable to incorporating the ASEP provisions into UN Regulations Nos. 9, 63 and 92 because they were ineffective for L categories of vehicles and would rather create difficulties in type approval procedures. However, he added that anti-tampering provisions were still needed to cover all L categories. The expert from IMMA recalled that the 07 series of amendments to UN Regulation No. 9 and the 02 series of amendments to UN Regulation No. 63, recently adopted, already introduced provisions of this kind. GRB agreed to resume consideration on this agenda item at its January 2014 session on the basis of possible concrete proposal that would cover the remaining issues.

20. GRB noted that during the Administrative Committee for the coordination of Work (AC.2) at the June 2013 session (ECE/TRANS/WP.29/1104, para. 19), the Chairs of the GRs suggested inserting the new provisions on revisions and extensions into the consolidated Resolution on the Construction of Vehicles (R.E.3) and referring in UN Regulations to that part of R.E.3. The expert from OICA informed GRB of her intention to submit a proposal at a later stage, awaiting the outcome of the IWVTA IWG on the same subject. GRB decided to keep this agenda item for its next session awaiting a concrete proposal from the expert of OICA.

21. GRB noted that no new information had been given under this agenda item.

22. GRB noted the absence of new information under this agenda item.

23. The expert from EC, secretary of the IWG on QRTV, informed GRB about the outcome of the last meeting of QRTV held in Washington, D.C. from 16 to 18 July 2013. He also announced that the next meetings of his group were scheduled on 5-6 September in Geneva, from 8 to 10 October in Washington, D.C. and on 7 December 2013 in Tokyo. He stated that a concrete proposal of UN GTR was in progress and was keeping to the agreed time schedule. He added that among the most relevant issues to be discussed in the next meetings were the mandatory or optional activation of the audible vehicle alerting system (AVAS) when the vehicle is stationary and beginning motion. The expert from the Netherlands reiterated his concerns that the installation of such devices would shift the responsibility of the driver to vulnerable road users (such as visually impaired people) and suggested the mandatory installation of advanced emergency breaking system (AEBS) instead of AVAS. The expert from WBU, stated that his organization supports any technology that improves pedestrian safety. However, he added that AEBS would not eliminate the need for the AVAS. He further explained that if an approaching vehicle was coming from a certain distance (i.e. fifty or sixty feet) when the blind person steps onto the road, the AEBS might be effective. However, he argued that if the distance of the vehicle was closer (i.e. ten or fifteen feet), AEBS could cause potential harm to the passengers and endanger a following vehicle by its unexpected breaking action. Finally, he said that on the same basis there was evidence of the need for vehicle sound while it is stationary because of the ability of the electric and hybrid electric vehicles to start moving abruptly. At the request of GRB Chair and of the expert from EC, the experts from the Contracting Parties to the 1958 and 1998 Agreements expressed their views on the mandatory activation of AVAS in stationary and commencing moving of the vehicle. GRB noted that further discussion was needed to clearly indicate the way forward on this subject and encouraged experts to participate in the next meetings of QRTV.

24. The expert from IMMA expressed concerns on the possible inclusion of powered two wheelers (PTWs) in the scope of the UN GTR. He added that the specifications in the UN GTR were solely based on analyses applicable for four-wheeled vehicles. He suggested that the inclusion of PTWs should be considered on the basis of relevant data and analysis, taking into account the specifics and use of PTWs.

25. GRB recalled the recommendation of the Administrative Committee for the coordination of Work (AC.2) at the November 2012 session (ECE/TRANS/WP.29/1102, para. 12), that GRB would find a proper balance for noise limit values and minimum sound levels for QRTV equipped with AVAS. Therefore, the expert from France made a presentation (GRB-58-16), addressing this concern. He suggested fixing the purpose of the UN GTR development by avoiding excessive noise and preventing conflict with the future 03 series of amendments to UN Regulation No. 51. GRB agree to resume discussion at its January 2014 session on the basis of the outcome of the IWG on QRTV.

26. GRB agreed to resume discussion at its January 2014 session on the basis of GRB-57-12 and GRB-57-18 and of informal documents provided by the expert from CLEPA concerning UN Regulations Nos. 59 and 28 and by the expert from EC concerning QRTV.

27. GRB resumed consideration on ECE/TRANS/WP.29/GRB/2013/9 tabled by the expert from the Russian Federation. The expert from IMMA requested a study reservation on paragraph 8.8.21.2. including new categories of vehicles L6 and L7 not yet covered by UN Regulation No. 9. GRB agreed to resume consideration on this subject at its January 2014 session and for possible adoption of the proposal as a whole. Moreover, it was agreed to remove ECE/TRANS/WP.29/GRB/2012/12 and GRB-57-10 and GRB-57-11 from the agenda of the next meeting, awaiting possible new information from the ISO expert and revised proposals, if any.

28. GRB noted the decision of WP.29 at its March 2013 session to freeze the activities of the environmentally friendly vehicles (see ECE/TRANS/WP.29/1102, para. 76) and deleted this item from the agenda of its next sessions.

29. The expert from EC recalled WP.29-160-27 and WP.29-160-33, introduced at the June 2013 session of WP.29 and showing the scope for changes in the 1958 Agreement and UN Regulation No. 0, aiming at establishing an IWVTA. The expert from EC asked GRB if changes on the objectives were needed, especially, concerning UN Regulations Nos. 51 and 117. He informed GRB about the forthcoming subgroups (Subgroup on the 1958 Agreement and Subgroup on UN Regulation No. 0) meetings on IWVTA, scheduled from 11 to 13 September 2013 in Paris. The experts from ETRTO and OICA endorsed UN Regulation No. 51 inclusion at the IWVTA without splitting its provisions. The expert from ETRTO expressed concern that actually a new UN Regulation dedicated to tyre installation was still missing. GRB agreed to resume consideration on this subject at its January 2013 session awaiting the outcome of IWVTA informal group.

30. GRB considered ECE/TRANS/WP.29/2013/64 proposing an amendment to UN Rule No.1 (environment). However, it was noted that an amendment to the corresponding EU Directive was in progress. GRB agreed to defer the adoption of ECE/TRANS/WP.29/2013/64 awaiting the final revision of the corresponding EU Directive to fully harmonize them.

31. The Secretary reported on the highlights of the 159th and 169th session of WP.29 (ECE/TRANS/WP.29/1102 and ECE/TRANS/WP.29/1104).

32. The decision of WP.29/AC.2 to refer WP.29-160-39 to GRB for information was noted (see ECE/TRANS/WP.29/1104, para 18). GRB did not have comments on the document.

33. In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and ECE/TRANS/WP.29/690/Amend.1), GRB called for the election of officers. The representatives of the Contracting Parties, present and voting, elected unanimously Mr. Serge Ficheux (France) as Chair and Mr. Andrei Bocharov (Russian Federation) as Vice-Chair for the sessions of GRB scheduled in the year 2014.

Working Party on Noise | Session 60 | 1-3 Sep 2014

1. The Working Party on Noise (GRB) held its sixtieth session from 1 to 3 September 2014 in Geneva. The meeting was chaired by Mr. S. Ficheux (France). Experts from the following countries participated in the work following Rule 1(a) of the Rules of Procedure of the World Forum for Harmonization of Vehicle Regulations (WP.29) (TRANS/WP.29/690, Amend. 1 and Amend. 2): Austria; Belgium; China; France; Germany; Hungary; India; Italy; Japan; Netherlands; Norway; Poland; Republic of Korea; Russian Federation; Spain; Sweden; Switzerland; United Kingdom of Great Britain and Northern Ireland. Experts from the European Commission (EC) participated. Experts from the following non-governmental organizations also participated: European Tyre and Rim Technical Organisation (ETRTO); International Motorcycle Manufacturers Association (IMMA); International Organization for Standardization (ISO); International Organization of Motor Vehicle Manufacturers (OICA) and World Blind Union (WBU).

2. GRB considered and adopted the agenda.

3. Through a presentation (GRB-60-16), the expert from OICA introduced ECE/TRANS/WP.29/GRB/2014/4 proposing amendments to UN Regulation No. 28, in particular, a reduction the prescribed sound level of the audible warning device from 93 to 87 dB(A). While the expert from the Republic of Korea supported this proposal, the experts from India and IMMA requested a study reservation. GRB agreed to revert to this issue at its January 2015 session.

4. The expert from IMMA proposed to complete a table containing all symbols used in this UN Regulation with the symbols related to the additional sound emission provisions (ASEP) test (GRB-60-06). GRB adopted this proposal as reproduced in Annex II to this report and requested the secretariat to submit it to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their March 2015 sessions.

5. On behalf of the Informal Working Group (IWG) on UN Regulations Nos. 51 and 59, the expert from OICA introduced a revised proposal for the 03 series of amendments to UN Regulation No. 51 (ECE/TRANS/WP.29/GRB/2014/5). He explained that the text of this proposal was harmonized, as far as possible, with European Union (EU) Regulation No. 540/2014 on the sound level of motor vehicles and of replacement silencing systems, including a three-phase reduction of the sound level limits. GRB noted that, following the entry into force of phase 2 for new types of vehicles, EU would undertake a detailed study to review the limits of phase 3 and to correct these values, if deemed to be necessary. Other Contracting Parties were invited to conduct similar studies in the future and to transmit their outcomes to GRB. GRB stressed the importance of aligning the timeline for introduction of phases 1-3 of the 03 series of amendments to UN Regulation No. 51 with the step-by-step entry into force of the above EU Regulation. For this reason, GRB agreed that all transitional provisions of paragraph 11. of the proposal should refer to specific dates(i.e., dates identical to those of the EU phase-in). Finally, GRB adopted the proposal, as amended by Annex III to this report, and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions.

6. The expert from Japan suggested that references to ISO 10844:2011 be put in square brackets for the time being and requested GRB to revert to this issue at the next session.

7. The expert from OICA briefly introduced some additional elements which had been identified by IWG on UN Regulations Nos. 51 and 59 for further consideration and possible inclusion into the 03 series of amendments to UN Regulation No. 51 (GRB-60-01). The expert from ISO informed GRB about a new version of ISO 10844:2014 which added a few editorial modifications to the previous version ISO 10844:2014 without changes in the fundamental requirements (GRB-60-17). The expert from China introduced GRB-60-10-Rev.1 and GRB-60-15 in which he suggested higher limit values and a new classification for vehicles of a specific category available on the Chinese market. GRB requested the IWG on UN Regulations Nos. 51 and 59 to consider all these additional aspects and to prepare proposals for the next session, if necessary.

8. GRB noted that the additional sound emission provisions contained in ECE/TRANS/WP.29/2011/64 had been incorporated into the revised proposal for the 03 series of amendments to UN Regulation No. 51 (ECE/TRANS/WP.29/GRB/2014/5) and decided to remove ECE/TRANS/WP.29/2011/64 from the agenda.

9. On behalf of the IWG on UN Regulations Nos. 51 and 59, the expert from OICA presented a revised proposal for the 02 series of amendments to UN Regulation No. 59 (ECE/TRANS/WP.29/GRB/2014/6 and GRB-60-01). He pointed out that this proposal was also aligned with EU Regulation No. 540/2014 on the sound level of motor vehicles and of replacement silencing systems. GRB adopted this proposal, as amended by Annex IV to the present report, and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions.

10. No new information was given under this agenda item.

11. The expert from the Russian Federation introduced some clarifications to be included in UN Regulation No. 117, on data processing for the measurement method of tyre deceleration value obtained in differential form dω/dt (ECE/TRANS/WP.29/GRB/2014/7). GRB adopted this proposal, as amended by Annex V to this report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions.

12. The expert from ERTRO introduced ECE/TRANS/WP.29/GRB/2014/8 to propose new time measurement accuracy for instrumentation involved in the rolling resistance method (Annex 6 to the UN Regulation). The expert from Japan reiterated his reservation that the proposed accuracy might be too strict and asked GRB to postpone the consideration of this item to the next session. The expert from the Russian Federation agreed with this suggestion. GRB recalled that this issue had already been discussed several times and felt that a final decision should be taken at the next session. Meanwhile, experts from Japan, Russian Federation, ETRTO, as well as from other Contracting Parties were invited to finalize their consultations.

13. The expert from IMMA proposed to include the latest version of ISO 10844 on test tracks in UN Regulations Nos. 9, 41 and 63 and to introduce transitional provisions for passing from ISO 10844:1994 to ISO 10844:2011 (GRB-60-07). GRB supported the objective of this proposal and noted that new test tracks based on ISO 10844:2011 could also be used for extension of approvals granted under the previous series of amendments to UN Regulation No. 41. GRB invited IMMA, with the assistance of the secretariat, to revise this proposal using ECE/TRANS/WP.29/GRB/2014/2 as an example and to re-submit it as an official proposal to the January 2015 session of GRB.

14. The expert from the Netherlands presented the outcome of a study (GRB-60-08 and Add.1) of the shifts in tyre sound emission levels in his country between 2007 and 2013, i.e. before and after the revision of tyre noise limits in 2009 (EC/661/2009 and UN Regulation No. 117). The study addressed the most common C1, C2 and C3 tyres in terms of size and manufacturer. The reductions in tyre sound levels between 2007 and 2013 were found to be respectively 1.5, 1.4 and 1.1 dB(A) for C1, C2 and C3 tyres.

15. The expert from the Netherlands informed GRB about the results of two studies (GRB-60-03, GRB-60-13, GRB-60-14) commissioned by the Dutch Ministry of Infrastructure and Environment with a view to assessing cost savings that could be achieved in the Netherlands and EU by a switch from currently used tyres to high-performance tyres with A-labels on each parameter of the EU tyre label: energy efficiency, wet grip and noise (so called ‘triple-A’ tyres). According to the studies, moving towards ‘triple-A’ tyres could bring considerable potential benefits for the society in terms of energy, safety and noise reduction, which were estimated to be around 1 billion Euros in the Netherlands and 34 billion Euros in EU per year. In addition, individual consumers could also benefits from substantial fuel cost savings.

16. As a first reaction, the experts from ETRTO and OICA pointed out the rather theoretical character of some assumptions used for these studies, as well as the fact that ‘triple-A’ tyres were not yet available on the market. The expert from the Netherlands added that a common objective of these studies, together with the one mentioned in paragraph 22 above, was to shift the society to better tyres, either by introducing stricter limits or by raising the awareness of tyre labels. Finally, GRB agreed to include this issue in the agenda of its next session and invited experts to submit their comments for discussion.

17. The expert from the Russian Federation informed GRB that, as from January 2015, a new regional regulation on internal noise would come into force in the Russian Federation and other countries of the Customs Union. Detailed information on this regulation, together with the internal noise limits, will be presented at the next session of GRB. He recalled a GRB recommendation to develop, with ISO, a test method for interior noise and pointed out that this work had not yet started due to a lack of financing. GRB took note of this information.

18. The expert from the Netherlands introduced GRB-60-04 and Add.1 in which he pointed out that, under urban driving conditions, the rolling noise dominates the overall noise production and is influenced by the properties of the road surface (like surface texture, acoustical absorption and air‐pumping). Thus, improving the surface properties would result in a lower rolling noise level. According to the expert, quiet road surfaces are a valuable measure to reduce traffic noise, either on their own or in combination with other noise reducing strategies, and generally demonstrate a positive cost/benefit ratio.

19. The Chair stressed the importance of the tyre-road interaction for sound emissions and noted that, for the time being, GRB has no mandate for regulating road surfaces. GRB agreed to resume this discussion at its next session and looked forward to new studies and presentations on the issue.

20. The Chair informed GRB about the proposal of the technical sponsors of IWG on Quiet Road Transport Vehicles (QRTV) for GTR to develop a draft UN Regulation on QRTV under the 1958 Agreement in parallel to a draft GTR on QRTV (ECE/TRANS/WP.29/1110, para. 100). GRB agreed with this proposal and decided, subject to WP.29 consent, to establish an IWG to develop a UN Regulation on QRTV under the 1958 Agreement and adopted the Terms of Reference (ToR) (GRB-60-11-Rev.1), as reproduced in Annex VI to this report. The new IWG should work in close cooperation with IWG QRTV for GTR, with the aim to draft the above mentioned UN Regulation based on audible alerts for the safety of vulnerable road users. GRB agreed that the scope of a new UN Regulation would initially cover electric and hybrid electric vehicles of categories M and N. In a second phase, the scope may be extended.

21. GRB reviewed GRB-57-12 and GRB-57-18 containing definitions and acronyms in Regulations under the responsibility of GRB and requested OICA and IMMA to update these documents based on the 03 series of amendments to UN Regulation No. 51 and the 02 series of amendments to UN Regulation No. 59 adopted at the present session (see paras. 5 and 9 above), so that the final versions could be approved at the January 2015 session of GRB.

22. GRB was informed that the Working Party on Lighting and Light-Signalling (GRE) had identified the need to introduce definitions for new categories of vehicles into the Consolidated Resolution on the Construction of Vehicles (R.E.3), such as agricultural trailers and towed machinery. GRB noted several alternative proposals for the new definitions (ECE/TRANS/WP.29/GRSG/2014/25 and GRB-60-02) and invited experts to transmit their comments and suggestions, if any, to the secretariat.

23. On behalf the GRB Ambassador to IWVTA, the expert from EC reported on the progress made on Revision 3 of the 1958 Agreement and on the development of UN Regulation No. 0. At its June 2014 session, WP.29 had agreed to freeze the work on Revision 3 and to resume its consideration in November 2014 on the basis of political and legal guidance that the Contracting Parties had been requested to provide, in particular, on outstanding issues of proxy voting and the three-fourth or the four-fifth majority required for taking decisions. WP.29 had also approved a questionnaire on IWVTA which was subsequently distributed. The latest draft of Revision 3 of the 1958 Agreement is contained in ECE/TRANS/WP.29/2014/53 and ECE/TRANS/WP.29/2014/82.

24. The secretariat presented draft guidelines on amendments to UN Regulations (WP.29-163-10), including a new term “version of a UN Regulation” and a common commencement date (1 September each year) recommended for new series of amendments to all UN Regulations listed in the annex of UN Regulation No. 0. In this respect, the Chair recalled that for the 03 series of amendments to UN Regulation No. 51, the date of entry into force of phase 1 was fixed on 1 July 2016, in order to synchronize it with the entry into force of EU Regulation No. 540/2014 on the sound level of motor vehicles and of replacement silencing systems (see para. 5 above).

25. The secretariat reported on the highlights of the 162nd and 163rd sessions of WP.29 (ECE/TRANS/WP.29/1108, ECE/TRANS/WP.29/1110, GRB-60-05).

26. The expert from ISO informed GRB about a new standard ISO 362-3 on indoor testing of pass-by noise (GRB-60-09). The objective of this new standard is to provide a basis for the official recognition of an indoor-pass-by-test for type approval of road vehicles of categories M and N. GRB noted that the indoor testing according to ISO 362-3 does not depend on climatic conditions and could become an alternative to the outdoor testing as described in ISO 362-1. GRB decided to revert to this issue at the next session and invited all experts of GRB, as well as of the IWG on UN Regulations Nos. 51 and 59, to consider if a reference to ISO 362-3 could be incorporated into UN Regulation No. 51.

27. No issues were considered under this agenda item.

28. For its sixty-first session, scheduled to be held in Geneva from 27 (starting at 2.30 p.m.) to 29 (concluding at 5.30 p.m.) January 2015, GRB noted that the deadline for the submission of official documents to the secretariat was 31 October 2014, twelve weeks prior to the session.

29. In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and ECE/TRANS/WP.29/690/Amend.1), GRB called for the election of officers. The representatives of the Contracting Parties, present and voting, elected unanimously Mr. Serge Ficheux (France) as Chair and Mr. Andrei Bocharov (Russian Federation) as Vice-Chair for the sessions of GRB scheduled in the year 2015.
