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.

GRB-56-08 | Draft IMMA position regarding ECE/TRANS/WP.29/GRB/2012/5 Comments from the IMMA in response to the Russian proposal to re-define the use of terms "sound" and "noise" in the motorcycle noise regulation.

GRB-57-21 | Additional Clarifications for the Document GRB/2012/5 Russian response to IMMA's reservations concerning the definition and use of the terms "sound" and "noise" in Regulation No. 41 and other UN Regulations relating to noise.

GRB/2012/5 | Proposal for Supplement 1 to the 04 series of amendments to Regulation No. 41 Proposal from the Russian Federation to provide harmonized definitions for the terms "noise" and "sound" and also for a revised structure for introducing the provisions.

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.

GRB-56-04 | Proposal for draft amendments to the 04 series of the Regulation No.41 This proposal aligns Annex 3, paragraph 2.3.2. with the latest amendment to ISO 5130:2012. The purpose of the amendment is to require the use of test surfaces with "no appreciable level of porosity".

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).

GRB-57-17 | Proposal for amendments to add Transitional Provisions to Regulation No. 51.03 The transitional provisions in GRB/2012/08 are not in line with the latest UN Guidelines on Transitional Provisions. This proposal updates the transitional provisions and adds two amendments specifically applicable for UN Regulation No. 51.

GRB-57-20 | Proposal for amendments to UN Regulation No. 51.02 Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) in order to incorporate the latest stage of relevant ISO standards in UN Regulation No. 51, Revision 2.

GRB/2012/16 | Proposal for Supplement 8 to the 02 series of amendments to Regulation No. 51 Proposal from the Netherlands to update the requirements of the noise test track from ISO 10844:1994 to ISO 10844:2011, including provisions for the repaving of non-compliant tracks. The proposal offers two alternatives: reference to ISO 10844:2011 or reproducing the whole text of the standard.

GRB/2012/17 | Proposal for draft 03 series of amendments to Regulation No. 51 OICA submission proposing to align the current stationary vehicle noise emission measurement provisions of UN R51 with those in the latest draft international standard ISO/DIS 362.

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.

GRB-57-13 | Proposal of amendments to document GRB/2013/4 Proposal of two options for inserting provisions on tire dimensions into the amendment proposed in document GRB/2013/4 to revise the Annex 3 test procedures and interpretation of resulting data.

GRB/2013/4 | Proposal for Supplement 9 to the 02 series of amendments to Regulation No. 51 Proposed revisions to the Annex 3 test procedures and interpretation of resulting data. This is based upon informal document GRB-56-06.

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.

GRB-57-23 | Vehicle Noise: Analysis of Swiss database and EC, Germany, and Japan noise proposals

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.

GRB-57-23 | Vehicle Noise: Analysis of Swiss database and EC, Germany, and Japan noise proposals

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.

GRB-57-27 | Draft proposal of amendments to Regulation No. 59 Proposal for additional sound emission provisions (ASEP) to align UN R59 with parallel amendments to the main vehicle noise regulation, UN R51.

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.

GRB/2013/9 | Proposal for Amendment 2 to the Consolidated Resolution on the Construction of Vehicles Series of editorial corrections and clarifications to the resolution.

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.

GRB-57-03 | Proposal to amend the document GRB/2012/11 Amendments to the proposal to amend the snow test method for C3 tyres in order to prescribe the wider of the possible speed ranges. Corrects wording to replace “blocking differential” with “differential lock” and mandatory use of differential lock in certain cases.

GRB/2012/11 | Proposal for Supplement 3 to the 02 series of amendments to Regulation No. 117 Proposal from the European Tyre and Rim Technical Organisation (ETRTO) to amend the snow test method for C3 Tyres.

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.

GRB/2012/15 | Proposal for Supplement 3 to the 02 series of amendments to Regulation No. 117 Proposal from the Netherlands to update requirements on the noise test track to the from ISO 10844:1994 to ISO 10844:2011, including provisions for the repaving of non-compliant tracks. The proposal offers two approaches: reference to IS0 10844:2011 or reproduction of the ISO text.

GRB/2012/18 | Proposal for corrigendum to draft Supplement 3 to the 02 series of amendments to Regulation No. 117 Submission by the GRB secretariat to correct an editorial error where the noise test track specifications should refer to the requirements of ISO 10844:2011 rather than "Annex 4" as stipulated in the original draft.

GRB/2013/2 | Proposal for 03 series of amendments to Regulation No. 117 Proposal by the Chair and Vice-Chair of GRB to allow the use of the test track complying with ISO 10844:2011 in a new series of amendments to the UN R117. This is based upon document GRB-56-20 from the previous GRB session.

GRB/2013/5 | Proposal for Supplement 3 to the 02 series of amendments to Regulation No. 117 Proposal to update noise test-track requirements from ISO 19844:1994 to ISO 10844:2011 and incorporates transitional provisions to allow repaving of existing, non-compliant test tracks with the ISO 10844:2011 standards. This supersedes document GRB/2012/9.

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.

GRB/2013/3 | Proposal for Supplement 3 to the 02 series of amendments to Regulation No. 117 Proposal from the Russian Federation to elaborate on the concept of tyre deceleration (dω/dt) in the test technology. The proposal is based on informal document GRB-56-02 from the previous GRB session.

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.

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

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

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.

GRB-57-14 | Additional Sound Emission Provisions for UN Regulations Nos. 9, 63 and 92 Notice of the European Union's intention to accede to UN Regulation No. 41 and the possible accession to Regulations 9, 63, and 92. The EC requests GRB input before deciding whether to pursue a separate legislative process to establish new provisions for these related noise rules.

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.

GRB-57-16 | Proposal for amendments to Regulations Nos. 28, 51, 59 and 117 Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) in order to introduce the concept of “revision of approvals” in the regulations under GRB responsibility.

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.

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.

GRB-57-15 | Feasibility of a "noise profiling test" for electric and hybrid-electric vehicles Proposal to open discussions on a new test procedure and possibly noise-labeling requirements for electric-mode vehicles to ensure that approaching vehicle audible systems designed to enhance the safety of pedestrians, including the blind, do not negate the benefits of noise reduction.
