13. The expert from EC informed GRB about a study on how to enhance the sound test requirements for mopeds, three-wheeled vehicles in Regulations Nos. 9, 63 and replacement exhaust silencing systems for L categories (L1 to L5) in Regulations Nos. 92 before the European Union (EU) could accept these Regulations (GRB-63-18). This study included public consultations and had been launched in response to frequent requests by citizens to improve the sound level of mopeds and three-wheeled vehicles as well as of replacement silencers for all L-category vehicles. On a similar note, the expert from EC reported about the ongoing public consultations on the EU Environmental Noise Directive1 (GRB-63-18-Add.1).

14. Based on the outcome of the study, the expert from EC proposed a set of collective amendments to Regulations Nos. 9, 63 and 92 (GRB-63-03, GRB-63-05, GRB-63-07, GRB-63-08, GRB-63-09). The experts from France, Germany, IMMA and OICA delivered a number of remarks on these documents. GRB invited all experts to transmit their written comments, if any, to the expert from EC. Finally, GRB decided to continue consideration of these amendment proposals at its next session based on official documents to be submitted by the expert from EC.

Working Party on Noise | Session 62 | 1-3 Sep 2015

1. The Working Party on Noise (GRB) held its sixty-second session from 1 to 3 September 2015 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; Russian Federation; Spain; Sweden; Switzerland; United Kingdom of Great Britain and Northern Ireland and the United States of America. An expert from the European Commission (EC) participated. Experts from the following non-governmental organizations also participated: International Council of Academies of Engineering and Technological Sciences, Inc. (CAETS); 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. The expert from the Russian Federation introduced an updated text of Regulation No. 28, with the aim to align its provisions with the current rulemaking practice. (ECE/TRANS/WP.29/GRB/2015/7). This proposal received comments from the experts of France, India and OICA (GRB-62-20, GRB-62-18 and GRB-62-21-Rev.1, respectively). In particular, the expert from France proposed to include a modular approach to permit the introduction of other audible signals. GRB invited the expert from the Russian Federation to take these comments into account and to submit a revised document for consideration at the next session.

4. The expert from IMMA proposed to amend paragraph 8.2. of Regulation No. 41 on the conformity of production (ECE/TRANS/WP.29/GRB/2015/8), thus formalizing the interpretation agreed upon at the fifty-sixth session of GRB (ECE/TRANS/WP.29/GRB/54, para. 5). GRB adopted this proposal and requested the secretariat to submit it to the World Forum for Harmonization of Vehicle Regulations (WP.29) and the Administrative Committee (AC.1) for consideration and vote at their March 2016 sessions as a draft Supplement 4 to the 04 series of amendments to Regulation No. 41.

5. The expert from IMMA proposed to correct minor reference errors in Supplement 2 to the 04 series of amendments to Regulation No. 41 (GRB-62-05). GRB adopted this proposal, as contained in Annex II, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2016 sessions.

6. The expert from IMMA also proposed to extend, until 1 January 2018, the 1 dB(A) allowance for motorcycles tested in the second gear (GRB-62-15). Taking into account interventions of the experts from Germany and EC, GRB did not support this proposal.

7. GRB noted that WP.29 and AC.1, at their June 2015 sessions, had adopted the consolidated proposal for the 03 series of amendments to Regulation No. 51 (ECE/TRANS/WP.29/2015/62).

8. The expert from OICA proposed to clarify the wording of Annex 3, paragraph 3.1.3. (GRB-62-19-Rev.1). GRB adopted this proposal, as contained in Annex III, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2016 sessions as a draft Supplement 1 to the 03 series of amendments to Regulation No.51.

9. No new information was reported under this item.

10. No proposals were considered under this item.

11. No new information was reported under this agenda item.

12. The expert from the Netherlands presented a study (GRB-62-09 and Add.1) on noise emission from the Original Equipment Manufacturer (OEM) tyres of a specific size which were found to be around 1 dB(A) lower than the one from replacement tyres of the same size. The expert, thus, proposed to further reduce the limit values for OEM tyres in the 02 series of amendments to Regulation No. 117 (GRB-62-11 and Add.1).

13. The expert from Switzerland expressed his support for the general direction of the Dutch proposal. The experts from Germany and EC were of the view that, at this stage, it would be premature to tighten the tyre noise limits of Regulation No. 117. The expert from France called for a holistic approach to this issue. The experts from ETRTO and OICA expressed doubts about the representativeness of the tyre sample used in the Dutch study. The expert from ETRTO also delivered comments on the proposal for amendments to Regulation No. 117 (GRB-62-17). Finally, GRB invited all experts to further study the Dutch proposal and decided to revert to this issue at the next session.

14. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2015/27 and ECE/TRANS/WP.29/GRRF/2015/32 which would be considered at the forthcoming session of the Working Party on Brakes and Running Gear (GRRF) (15-18 September 2015). GRB experts were invited to review these documents and to provide their colleagues in GRRF with comments, if any.

15. The expert from IMMA proposed collective amendments to Regulations Nos. 9, 41, 63 and 92 to clarify that the provisions on fibrous materials are only applicable if such materials are in contact with exhaust gases (GRB-62-06-Rev.1). Following comments by the experts from Germany and OICA, GRB invited IMMA to revise the proposal and re-submit it to the next session, possibly as an official document.

16. The expert from China briefed GRB on the activities of the China vehicle noise standards working group (GRB-62-10). The experts from Japan informed GRB about the trends of noise regulation in Japan and gave an overview of the future policy for motor vehicle noise reduction (GRB-62-13-Rev.1 and GRB-62-12, respectively). The expert of ISO reported on the activities of his organization on interior noise, with the aim to review ISO 5128 (GRB-62-07). GRB took note of these presentations and felt that some of the issues raised could be included in the programme of work of GRB (see para. 27 below).

17. The expert from the Netherlands presented a policy indicator for road traffic noise emissions (GRB-62-14 and Add.1) that determines the effect of noise control at source on average noise levels at the dwelling facade and on estimated numbers of annoyed and sleep disturbed people. According to the expert, the indicator had been calculated for the Netherlands, showing a potential reduction of up to 50 per cent in annoyed and sleep disturbed people, if tighter limits for vehicles and tyres were introduced and road surfaces were improved. He also suggested that the policy indicator be applied for the whole EU. The experts from ETRTO and OICA commented on the proposed concept. The Chair proposed to continue the discussion in the future, taking into account comments from the industry.

18. The expert from the Netherlands briefed GRB on the Dutch public campaign “Choose the Best Tyre” and on potential benefits of energy-efficient tyres and correct tyre pressure maintenance (GRB-62-01 and Add.1, GRB-62-02-Rev.1). The Chair recalled other Dutch studies on this topic and commended the experts from the Netherlands for the considerable work undertaken and interesting results. He also called for a holistic approach and closer cooperation between the governments and industry in this area.

19. The expert from the Belgian Road Research Centre (BRCC) presented a new solution for noise reducing pavements, namely the poro-elastic road surface which provides for extreme noise reduction in a range from 7 to 12 dB(A) (GRB-62-23). GRB thanked BRCC for this presentation and looked forward to further studies and presentations on the issue.

20. The experts from France and Germany, in their capacity of Co-chairs of the Informal Working Group (IWG) on a Quiet Road Transport Vehicles (QRTV) Regulation under 1958 Agreement, presented a draft QRTV Regulation (ECE/TRANS/WP.29/GRB/2015/9 and GRB-62-22).

21. The expert from WBU called for shared responsibility of drivers and vulnerable road users for road safety and requested that the Audible Vehicle Alert System (AVAS) of QRTV be “ON” while the vehicle is stationary and that the driver should not be able to deactivate (or pause) AVAS (GRB-62-03). He also referred to a study (GRB-62-16) suggesting that the proposed AVAS level of sound did not seem to make QRTV with AVAS more detectable to the average blind person than was QRTV without AVAS. According to the study, more research would be needed to determine a minimal noise level that would satisfy the desire to reduce noise emissions while remaining safe for pedestrians.

22. GRB recalled that AVAS provisions had been recently adopted in the European Union and were scheduled to be announced in the United States of America in November 2015. Therefore, GRB stressed the urgent need for a QRTV Regulation and decided to adopt ECE/TRANS/WP.29/GRB/2015/9, subject to minor editorial corrections. The secretariat was requested to submit it to WP.29 and AC.1 for consideration and vote at their March 2016 sessions. At the same time, GRB was of the view that the concerns raised by WBU should be studied further, also bearing in mind recent technologies that improve road safety. To address these issues, GRB agreed that the mandates of both IWG QRTV for a Regulation and IWG QRTV for a GTR should be extended and requested the Chair to seek the WP.29 consent.

23. GRB noted that WP.29, at its March 2015 session, had considered a list of acronyms and abbreviations used in Regulations (WP.29-165-17) and noted that the acronym RESS “Replacement Exhaust Silencing System” is used in Regulation No. 92. However, RESS is widely used as “Rechargeable Energy Storage System”, for example, in Regulations Nos. 10, 12, 94, 95 and 100. For this reason, WP.29 had requested GRB to introduce, in the medium term, an alternative acronym for “Replacement Exhaust Silencing System” in Regulation No. 92 (WP.29-165-16). GRB invited experts and, in particular, IMMA to study this issue and decided to revert to it at the next session.

24. No proposals were introduced under this item.

25. The secretariat informed GRB about the recent activities of the Subgroup on UN Regulation No. 0, in particular, about its proposal to introduce a new concept of “IWVTA vehicle type” which would group vehicles of a given type and with the same level of conformity.

26. The secretariat reported on the highlights of the 165th and 166th sessions of WP.29 (ECE/TRANS/WP.29/1114, ECE/TRANS/WP.29/1116, GRB-62-04).

27. The Chair presented a list of possible issues for the future GRB activities prepared at an informal meeting convened by the Chair in July 2015 (GRB-62-08). Various experts expressed their interest in pursuing specific items on the list and/or proposed new subjects. To take these comments into account and to prepare an updated and prioritized list, the Chair informed GRB about his intention to convene a second meeting of stakeholders at the beginning of December 2015, the results of which would be reported to the next session of GRB.

28. GRB was informed that Mr. Georges Dimitri (ETRTO) would retire and no longer attend its sessions. GRB thanked him for his contributions and wished him a happy retirement.

29. GRB took note that Mr. Masahito Yamashita (Japan) would no longer attend its sessions. GRB thanked him for his contributions and wished him success in his future career.

30. For its sixty-third session, scheduled to be held in Geneva from 16 (starting at 2.30 p.m.) to 18 (concluding at 5.30 p.m.) February 2016, GRB noted that the deadline for the submission of official documents to the secretariat would be 23 November 2015, twelve weeks prior to the session.
