No objections to the proposal which is passed for consideration to adopt during the AC.1 session.Go to session report
1. The Working Party on Noise (GRB) held its fifty-ninth session from 28 (afternoon) to 30 (morning) January 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; China; France; Germany; Hungary; India; Italy; Japan; Latvia; Netherlands; Norway; Russian Federation; Serbia; South Africa; Spain; Sweden; Switzerland; Turkey; 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 (ECE/TRANS/WP.29/GRB/2014/1 and Corr.1) proposed for the fifty-ninth session with the new agenda items 16(a) “Regulation No. 28 (Audible warning devices)”, 16(b)“Exchange of views for the future programme of work of GRB” and 16© “Provisional agenda for the sixtieth session”.
3. GRB resumed consideration of ECE/TRANS/WP.29/GRB/2012/5, tabled by the expert from the Russian Federation. The expert from IMMA stated that, although he supports the objective of correct usage of the terms “noise” and “sound” as well as clarifications in terminology related to noise reduction systems, IMMA wishes to avoid confusion with different application of these terms in UN Regulations Nos. 9, 41, 63 and 92, if the proposed amendments were approved. He added that in regards to the proposed reference in the type approval documentation to the type of catalyst, he was awaiting from the Russian experts the evidence in test results showing the influence of the catalyst type on the level of noise of L category vehicles.
4. The expert from the Russian Federation referred to his informal discussion with IMMA, where it was concluded that it would be more appropriate to introduce the amendments similar to those presented in ECE/TRANS/WP.29/GRB/2012/5 together in all UN Regulations related to noise of L category vehicles and to incorporate such amendments together with other proposals which are expected to be prepared following the development of the relevant legislation of the European Union. Taking this into account, the expert from the Russian Federation withdrew ECE/TRANS/WP.29/GRB/2012/5 for the time being, bearing in mind the introduction of similar proposals into all UN Regulations related to L category vehicle noise in the future.
5. GRB resumed discussion on the issue of transitional provisions, as contained in GRB-58-11-Rev.1, aligning the earlier adopted draft Supplement 1 to the 04 series of amendments to UN Regulation No. 41 (ECE/TRANS/WP.29/GRB/57, Annex II) to the General Guidelines for UN Regulatory Procedures and Transitional Provisions in UN Regulations (ECE/TRANS/WP.29/1044/Rev.1). GRB agreed to wait for the revision of the 1958 Agreement which would also introduce new rules for transitional provisions. Meanwhile, GRB agreed to keep this issue as a reference in its agenda for the future sessions.
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 184.108.40.206. 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 220.127.116.11 (sound limit values and categories of vehicles) introducing exceptions for limit values applicable to certain categories of vehicles.
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.
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.
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.
13. GRB noted that this agenda item was de facto covered in the framework of the discussion under agenda item 3(a). Thus, GRB agreed that, for its next session, agenda items 3(a) and 3 (b) should be combined and mention as references only GRB-59-04-Rev.1 and GRB-59-10-Rev.1. Finally, GRB agreed to remove ECE/TRANS/WP.29/GRB/2012/7, GRB-58-08, GRB-58-09, GRB-58-10, GRB-58-14 and GRB-58-17-Rev.1 from the agenda of the next session.
14. GRB recalled its intention to review the Additional Sound Emission Provisions (ASEP) and to refine the purpose of the new noise limit values (ECE/TRANS/WP.29/GRB/52, paras. 8–9). As no new information had been given under this agenda item, GRB agreed to keep it on the agenda for the next session.
15. In the absence of the expert from CLEPA, GRB agreed to defer discussion on this subject to its September 2014 session and to keep ECE/TRANS/WP.29/GRB/2013/8 and GRB-58-05 as references in the agenda of the next meeting, awaiting the outcome of discussion of the IWG on UN Regulations Nos. 51 and 59.
16. No new information was given under this agenda item.
17. The experts from France, the Russian Federation and ERTRO informed GRB (GRB-59-07 and GRB-59-08) about the outcome of their ad hoc meeting on testing the “Deceleration Calculator” software proposed by the Russian Federation for the deceleration test method using the dω/dt form for measuring rolling resistance. GRB noted that the ad hoc meeting had been hosted by the Technical Union for the Automobile, Motorcycle and Cycle Industries (UTAC), and generally included both theoretical justification of the method and its experimental assessment by determining rolling resistance of a sample tyre of class C1 using two test machines of different types. GRB also noted that the obtained data, its processing and statistical assessment had demonstrated good adaptability of the software to the tyre test machines and satisfactory reproducibility of deceleration data. Moreover, the algorithm of the “Deceleration Calculator” practically provides independence of the measured deceleration from the test speed range in span from 4 to 20 km/h.
18. Therefore the expert from the Russian Federation proposed GRB-59-02 superseding ECE/TRANS/WP.29/GRB/2013/10, as an alternative for measurements and data processing for deceleration value obtaining in differential form dω/dt.
19. GRB agreed in principle with the proposed method. However, given the late availability of GRB-59-02, GRB suggested that this document, accompanied by other supporting materials (GRB-59-07 and GRB-59-08), be first submitted to the forthcoming February 2014 session of GRRF for discussion and then, together with GRRF comments, transmitted as an official document to the next GRB session in September 2014 for final consideration. In the meantime, it was noted that results of testing tyres of commercial vehicles (classes C2 and C3) could also become available for that session of GRB. Finally, GRB invited experts to provide comments, if any, to the secretariat before the next GRB session.
20. The expert from ERTRO introduced GRB-59-03 containing a revised proposal for new time measurement accuracy for instrumentation involved in the rolling resistance method, with the aim to correct inconsistencies in Annex 6 to the UN Regulation. The proposal text was also supported by the experts from the Russian Federation. The expert from Japan raised a study reservation to verify the consequences of the change of accuracy. The expert of the European Commission raised similar concerns and stated that he would need first to discuss this matter with ERTRO on a bilateral basis. GRB agreed to resume consideration on this subject at its September 2014 session and requested the secretariat to distribute GRB-59-03 with an official symbol
21. The expert from EC informed GRB that EU intended to apply to these Regulations, but would need additional research, in particular with regard to tampering of silencers. To this end, a study would be launched before the next session of GRB in September 2014. Pending EU contributions, GRB decided to keep this issue on the agenda. The expert of IMMA made note that anti-tampering provisions were already introduced in the last amendments of these UN Regulations. Finally, GRB agreed to change the title of this agenda item to “additional provisions”, to distinguish it from agenda item 3© and to resume discussion on this subject at its September session on the basis of new information provided by the expert from EC.
22. GRB agreed to delete this item to the agenda of its next session [and/or] until a new proposal by the expert from OICA was submitted.
23. GRB noted that no new information had been given under this agenda item.
24. GRB welcomed a presentation by the expert from the Foundation for Scientific and Industrial Research (SINTEF, Norway) outlining the first results of a study concerning the
influence of the road surface on tyre rolling sound emission. The expert from SINTEF clarified that the main objective of the project was to investigate the noise performance of normal passenger car tyres on typical road surfaces in the Nordic countries (Denmark, Norway and Sweden) and to clarify which combinations of road surfaces and tyres will yield the lowest tyre/road noise levels. GRB noted that the results of this investigation had demonstrated the variation in noise levels of tyres around 4 dB(A) and the same variation between average of road surfaces. It was also noted that the difference between the most noisy tyre on the most noisy surface and the most quiet tyre on the quietest road surface had been found to be 11 dB(A). Finally, the expert from SINTEF informed GRB that during 2014, the project would be extended to truck tyres.
25. The expert from EC, secretary of IWG for QRTV, informed GRB about the outcome of its last meeting held in Tokyo (10 – 12 December 2013). He also announced that the next meetings of the IWG were scheduled to take place from 7 to 9 April as well as from 13 to 15 May, 2014 in Washington, D.C. He clarified that the IWG activities were focused on cleaning up the draft text of the UN GTR on QRTV as well as on addressing technical and policy issues. The expert from EC thus invited GRB experts from Contracting Parties to the 1998 Agreement to provide before April 2014 their comments on the various policy options, provided by a working paper of the IWG (AVAS conditions 27.01.14). GRB also noted the decision of the Executive Committee of the 1998 Agreement (AC.3) (see ECE/TRANS/WP.29/1106, para. 106) to extend the mandate of IWG until November 2015. Therefore, GRB expected to discuss a concrete proposal at its next sessions in September 2014 and January 2015.
26. The expert from WBU highlighted three key elements of AVAS, from the point of view of people with impaired vision: (i) alert sound should be of a sufficient volume and its composition (frequency, etc.) should allow for location and movement of the vehicle; (ii) the system should be active on stationary vehicles; and (iii) the driver should not be in a position to switch it off, as this safety feature should be active all the time. The expert from EC informed GRB that the EU Regulation on noise would require an automatic setting of AVAS and since this Regulation was at the latest stage of the co-decision process, this provision would hardly change. The Chair of GRB clarified that the pause-switch function would be part of the discussion of GRB. He added that the provisions of the UN GTR should conjugate the safety effectiveness of AVAS and the reduction of parasite noise. Finally, GRB agreed to resume discussion on this subject at its September 2014 session.
27. GRB resumed consideration of definitions and acronyms in UN Regulations and UN Global Technical Regulations under the responsibility of GRB on the basis of GRB-57-12 and GRB-57-18. The Chair of GRB stressed the importance of preparing a full and consistent list of acronyms and abbreviations with a view to avoiding any ambiguity in this area. It was agreed that this list covering both the 1958 and 1998 Agreements would then be submitted to WP.29 for approval and would be updated from time to time. GRB reiterated its invitation to all experts to provide their contributions, if any, so that the final document could be approved at the September 2014 session of GRB.
28. GRB considered document GRB-59-01 in which the secretariat proposed to correct the reference to Annex 3 of UN Regulation No. 41 in paragraph 18.104.22.168.2. of the Consolidated Resolution (R.E.3) as well as to draw the attention of the Working Party to the fact that the margin of 5 dB(A) defined in paragraph 22.214.171.124., in order to take into account the possible instrumental and measurement errors, substantially exceeds the respective margins of 1 or 3 dB(A) set out in Regulations No. 51, 41 and 63. The experts from France, Germany, Sweden, IMMA, ISO and OICA pointed out that the figure of 5 dB(A) in paragraph 126.96.36.199. takes into account the disturbances and scatter of measurements performed under real-life conditions, in uncertain acoustic environment (e.g. side of a road) and by untrained staff (e.g. road police), while the margin of 3 dB(A) is intended for laboratory conditions and trained staff. GRB decided to leave the figure of 5 dB(A) in paragraph 188.8.131.52. of R.E.3 unchanged.
29. Finally, GRB considered ECE/TRANS/WP.29/GRB/2013/9 tabled by the expert from the Russian Federation. GRB agreed, as proposed by the expert from IMMA, to delete, in the new paragraph 184.108.40.206.2., the references to new categories of vehicles L 6 and L 7 which are not yet covered by UN Regulation No. 9. Finally, GRB adopted ECE/TRANS/WP.29/GRB/2013/9, as amended by Annex III to this report. The secretariat was requested to submit it to WP.29 and AC.1 for consideration and vote at their June 2014 session as draft Amendment 5 to R.E.3.
30. GRB noted the good progress made by the WP.29 IWVTA informal groups on the Revision of the 1958 Agreement (SG58) and on the development of UN Regulation No. 0 (SGR0) at their recent informal meetings held in Sendai (Japan) in January 2014. It was noted that SG58 considered the unresolved issues (kept in square brackets) of the draft Revision 3 to the 1958 Agreement (ECE/TRANS/WP.29/2014/26) and had agreed on the final text. The final text of the draft Revision 3 to the 1958 Agreement will be submitted to WP.29 for consideration at its March 2014 session, on the basis of an informal document supplementing the official document.
31. SGR0 finalized a first draft of UN Regulation No. 0 on IWVTA, which will be presented at the forthcoming session of WP.29 in March 2014 as an informal document. GRB noted that UN Regulations Nos. 28, 51 (either in its current form or 03 series of amendments) and 117, would be included in IWVTA. Concerning the need to develop a new UN Regulation dedicated to tyre installation, GRB noted that this issue would be dealt with by GRRF. Finally, the Chair of GRB suggested that the following experts sponsor the above-mentioned UN Regulations in the IWVTA: (i) CLEPA (UN Regulation No. 28), (ii) OICA (UN Regulation No. 51) and (iii) ETRTO (UN Regulation No. 117).
GRB decided to delete this issue from the agenda.
33. The Secretary reported on the highlights of the 161st session of WP.29 (ECE/TRANS/WP.29/1106).
34. The expert from OICA introduced GRB-59-06-Rev.1 to update the test conditions and provisions of UN Regulation No. 28: (i) to allow the test of the audible warning devices on the vehicle with its engine warmed-up and at idle and (ii) to reduce the prescribed sound level from 93 to 90 dB(A). He justified the second point because this reduced level was audible far enough to instantaneously warn pedestrians and other road users, including drivers, as it was typically 20 dB to 40 dB higher compared to typical traffic noise and could also contribute to lowering the noise pollution. The experts from Italy and ISO supported this proposal. The expert from France underlined that the whole text should be revised to update the test methods and that the limit proposed by OICA should be discussed. GRB agreed to resume discussion on this issue and requested the secretariat to distribute GRB-59-06-Rev.1 with an official symbol at its September 2014 session.
35. At Chair’s invitation, GRB had a brief exchange of views on issues which should be included in the future work of GRB. The expert from ISO pointed out that, to update the test methods set out in UN Regulations Nos. 41 and 51, the following ISO activities may be relevant: revisiting ISO 362-1:2007, development of part III of this standard with a specification how to perform tests in indoor facilities and updating the requirements on the noise test track from ISO 10844:1994 to ISO 10844:2011. The expert from France mentioned UN Regulation No. 51, ASEP, QRTV, ongoing technological improvements, indoor approvals, addressing sirens (ambulances, etc.) in UN Regulation No. 28, noise pollution caused by loading and unloading of deliveries in cities. The expert from the Netherlands presented a graph (GRB-59-11) showing a general improvement in tyre noise data for C1 tyres in 2007-2013 and informed GRB about his intention to bring similar graphs for C2 and C3 tyres for the attention of GRB at its next session, with the aim to study if the current noise limits for tyres can be further reduced. With support from the experts from EC and OICA, he also suggested studying the correspondence between the labelling system on tyres and their actual performance. The expert from Switzerland was of the opinion that noise pollution, its benchmarking and new technologies emerging on the market should be looked at. The expert from ERTRO proposed to address the issue of road surfaces, as the third main contributor to noise pollution after vehicles and tyres. However, the Chair and the expert from EC pointed out that this issue is very complex and it goes beyond the competence of GRB and type approvals. The expert of EC proposed to revisit the noise emission of agricultural vehicles and update the underlying test methods which had been developed 40 years ago.
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.
