GRB-60-01 | Proposal for additional amendments to the draft the 03 series of amendments to Regulation No. 51
GRB/2014/6 | Proposal for the 02 series of amendments to Regulation No. 59
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.
1. The Working Party on Noise (GRB) held its sixty-first session from 27 to 29 January 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; Republic of Korea; Russian Federation; Spain; Sweden; Switzerland; United Kingdom of Great Britain and Northern Ireland. Expert from the European Commission (EC) participated. Experts from the following non-governmental organizations also participated: Conference of European Directors of Roads (CEDR); 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. In her opening statement Ms. Eva Molnar, Director, UNECE Transport Division, informed GRB about the recent appointment of Mr. Walter Nissler as Chief, Vehicle Regulations and Transport Innovations Section. She also mentioned the ongoing global negotiations on the Sustainable Developments Goals (SDG), which should replace the Millennium Development Goals (MDG) as of 2016, and argued in favour of including transport related goals into SDG. In this context, she introduced a new edition of the UNECE publication “Transport for Sustainable Development” addressing issues of transport safety, security and environmental performance of vehicles. Finally, she briefed GRB on the highlights of the forthcoming session of the Inland Transport Committee (24-26 February 2015).
3. GRB considered and adopted the agenda.
4. GRB resumed discussion on ECE/TRANS/WP.29/GRB/2014/4 by OICA proposing amendments to UN Regulation No. 28, in particular, a reduction in the prescribed sound level of the audible warning device from 93 to 87 dB(A). The expert from IMMA suggested further changes to this proposal (GRB-61-07). GRB adopted the proposal, as amended by Annex II to this report, and mandated the secretariat to submit it to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2015 sessions as draft Supplement 4 to the original series of amendments to Regulation No. 28. GRB noted that the adopted modification of the prescribed sound level makes this requirement less stringent and, thus, does not need a new series of amendments with transitional provisions.
5. The expert from the Russian Federation pointed out that Regulation No. 28 had not been updated for a long time and proposed a number of editorial modifications (GRB-61-12). GRB welcomed this initiative and decided to consider it at the next session, based on an official document to be submitted by the expert from the Russian Federation.
6. The expert from IMMA proposed to introduce the calculated engine speed for various types of transmission into Regulation No. 41 (ECE/TRANS/WP.29/GRB/2015/2 and Corr. 1, Corr. 2). GRB adopted the proposal and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2015 sessions as a draft Supplement to Regulation No. 41.
7. The expert from IMMA also proposed to amend paragraph 8.2. of Regulation No. 41 on the conformity of production (GRB-61-11). GRB decided to address this issue at the next session on the basis of an official document by IMMA.
8. On behalf of the Informal Working Group (IWG) on UN Regulations Nos. 51 and 59, the expert from OICA introduced further proposals for amendments to the 03 series of amendments to UN Regulation No. 51 (ECE/TRANS/WP.29/GRB/2015/3 and Corr.1). The expert from Japan expressed concerns about a relaxation clause for a specific category of vehicles included in these proposals (GRB-61-05) and proposed an alternative wording. Further corrections were suggested by the experts from the Netherlands (GRB-61-08), Spain, the European Commission and OICA. Finally, GRB adopted the proposals, as amended by Annex III to this report.
9. GRB recalled that, at its previous session, it had adopted the draft 03 series of amendments to Regulation No. 51 (ECE/TRANS/WP.29/GRB/2014/5, ECE/TRANS/WP.29/GRB/58, para. 5 and Annex III) which had subsequently been submitted to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as document ECE/TRANS/WP.29/2015/3. With regard to the additional proposals adopted at this session (para. 8 above and Annex III to this report), GRB noted two options for their processing:
10. GRB supported option (ii) and mandated its Chair to report about this decision to WP.29, AC.1 and the Administrative Committee for the Coordination of Work (AC.2) at their sessions in March 2015. GRB also noted that IWG on UN Regulations Nos. 51 and 59 had completed its tasks and that the extension of its mandate was not necessary.
11. No new information was reported under this item.
12. GRB considered additional proposals for the 02 series of amendments to Regulation No. 59 prepared by IWG on Regulations Nos. 51 and 59 (ECE/TRANS/WP.29/GRB/2015/4). GRB adopted these proposals, as amended by Annex IV to this report, and mandated the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their June 2015 sessions as a draft Supplement 1 to the 02 series of amendments to Regulation No. 59.
13. No new information was given under this agenda item.
14. GRB continued its consideration of the revised proposal for new time measurement accuracy for the rolling resistance method (ECE/TRANS/WP.29/GRB/2014/8). The expert from Japan introduced several modifications to this proposal (GRB-61-06). GRB adopted the proposal, as contained in Annex V to this report, and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2015 sessions as a draft Supplement 8 to the 02 series of amendments to Regulation No. 117. GRB also noted that the Working Party on Brakes and Running Gear (GRRF), at its February 2015 session, would consider a corrigendum to Supplement 6 to the 02 series of amendments to Regulation No. 117 (ECE/TRANS/WP.29/GRRF/2015/9).
15. The expert from France presented the results of testing tyres of commercial vehicles (classes C2 and C3) for the deceleration test method using the dω/dt form for measuring rolling resistance (GRB-61-09). The aim of this study was to compare the measurements obtained at a dedicated and non-dedicated rolling resistance machine. The results at the non-dedicated rolling resistance machine demonstrated a poor repeatability of the measurements, thus leaving open the question whether or not such machines are suitable for the proposed deceleration test method. GRB was of the view that further studies would be necessary and encouraged other laboratories to conduct such tests.
16. The expert from ETRTO referred to the ongoing work of updating references to the new version of ISO standard 10844:2014 (see para. 17 below) and proposed similar amendments to Annex 3 of Regulation No. 117 (GRB-61-14). The expert of ISO recalled his presentation on the comparison between the 2014 and 2011 versions of ISO 10844 (GRB-60-17) and confirmed that only editorial modifications had been introduced without any technical changes. Thus, GRB agreed that no transitional provisions were required in this case. GRB adopted the proposal, as contained in Annex VI to this report, and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2015 sessions as a draft supplement to Regulation No. 117.
17. The expert from IMMA proposed collective amendments to Regulations Nos. 9, 41 and 63 to introduce the recently published standard ISO 10844:2014 and to align the transition provisions for new type approvals and extension to approvals (ECE/TRANS/WP.29/GRB/2015/5 and GRB-61-13). GRB adopted these proposals, as contained in Annexes VII, VIII and IX to this report, and mandated the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their June 2015 sessions.
18. The expert from the Netherlands recalled the two studies presented at the previous session of GRB and introduced further arguments for tightening tyre noise limits in Regulation No. 117, together with the text of draft amendments (GRB-61-03 and Add.1). The expert from ETRTO questioned if the pool of tyres selected for the Dutch studies had indeed been a representative sample (GRB-61-18). He further pointed out that, for the time being, the tyre industry was busy meeting the requirements of 02 series of amendments to Regulation No. 117 which had recently come into force, in November 2012. According to him, until the completion of this process by 2018-2020, it would be premature to consider further reducing of tyre noise limits. The experts from China, Norway and Switzerland agreed that the proposal by the Netherlands needed further study. The experts from France and Germany pointed out various problems with labelling of tyres. GRB invited experts to provide their comments on the Dutch proposal and decided to revert to this issue at the next session on the basis of a new informal document containing the draft amendment proposals tabled by the expert from the Netherlands in GRB-61-03.
19. The expert from the Russian Federation presented historical developments of health standards and regulations on internal noise in the former Soviet Union and the Russian Federation (GRB-61-17). He also informed GRB that, as from 1 January 2015, a new regional regulation had come into force in the Customs Union establishing obligatory values for internal noise. He further clarified that his presentation was only for information purposes and that any concrete proposals could only be submitted to GRB when standard ISO-5128 on measuring internal noise, dated back to 1980, would be updated. The expert from ISO reported on ISO activities in this respect. The Chair proposed to keep this issue in the agenda and, as a first step, to consider if the methods for measuring inside noise in the Consolidated Resolution on the Construction of Vehicles (R.E.3) should be updated.
20. The expert from the Netherlands presented a discussion paper (GRB-61-01 and Add.1) exploring the possibility of introducing a noise label system for vehicles and providing an initial model for such labelling. In particular, he suggested that a labelling system for private cars rely on scores for interior noise, powertrain noise (engine and exhaust system), and tyre noise. The experts from Austria, France, Germany and OICA raised practical questions regarding the potential advantages of such a labelling system for customers. The expert from the European Commission pointed out that labelling falls under the competence of the Community and that the EU internal procedures should be followed. GRB decided to come back to this issue at the next session.
21. The expert from CEDR presented the experiences of his organization and its members regarding the use of noise reducing pavements (GRB-61-16). Such pavements were found to be more cost-effective than noise barriers and to reduce noise levels with 2 to 3 dB (max. 6 dB). On the other hand, the lifetime of noise reducing pavements is less than the one of non-noise reducing pavements and the investment costs of noise reducing pavements is higher than the costs of non-noise reducing pavements.
22. GRB noted that three factors contribute to the overall noise production: vehicles, tyres and road surfaces. Thus, a holistic approach should be followed to reduce sound emissions. The Chair recalled that, at present, UN Regulations do not address the issue of road surfaces and that GRB has no mandate for regulating pavements. GRB agreed to continue this discussion at its next session and looked forward to new studies and presentations on the issue.
23. The expert of WBU presented a position paper (GRB-61-15) with concerns about an Audible Vehicle Alert System (AVAS) of Quiet Road Transport Vehicles (QRTV). He stressed that AVAS must fulfil four criteria, namely presence, direction, location and operation of a hybrid electric or electric vehicle. He further explained that the AVAS sound must be detectable and locatable, AVAS must be on while the vehicle is stationary and that the driver should not be able to switch off (or pause) AVAS.
24. The experts from France and Germany, co-chairing IWG QRTV for a UN Regulation, briefed GRB on the progress in preparing a draft UN Regulation on QRTV under the 1958 Agreement and on its key aspects (GRB-61-02, GRB-61-10). GRB noted that a draft Regulation would be officially submitted to the next session of GRB in September 2015, as foreseen by the IWG mandate. The Chair invited GRB experts to provide IWG with their comments on a draft QRTV regulation as soon as possible and/or to take part in the work of IWG.
25. GRB confirmed that, for the time being, a new QRTV Regulation would cover electric and hybrid electric vehicles of categories M and N only. GRB agreed that stationary noise and the pause-switch function would be optional in stage 1. GRB also agreed that a maximum AVAS sound level should be introduced into a QRTV Regulation, with a view to protecting environment. The expert of WBU concurred with this view.
26. The Chair recalled that IWG QRTV for a UN Regulation should be working in close cooperation with IWG QRTV for GTR. He also pointed out that IWG QRTV for GTR would ask WP.29 to extend its mandate for one year.
27. GRB noted that, in line with the WP.29 decision, the secretariat was preparing a concept of a central register in which acronyms used by WP.29 as well as definitions used in UN Regulations and UN GTRs would be listed. In this context, GRB reiterated its request to OICA and IMMA to update documents GRB-57-12 and GRB-57-18 containing definitions and acronyms in Regulations under the responsibility of GRB.
28. GRB was informed that the Working Party on Lighting and Light-Signalling (GRE) had approved draft definitions for agricultural trailers and towed machinery, to be included into the Consolidated Resolution on the Construction of Vehicles (R.E.3) (ECE/TRANS/WP.29/2015/35). GRB invited experts to transmit their comments and suggestions, if any, to the secretariat.
29. The secretariat informed GRB about the current situation in Revision 3 of the 1958 Agreement, development of IVWTA and the Database on Exchange of Type Approval documentation (DETA) and highlighted the recent changes in the draft text of Revision 3 made at the November 2014 session of WP.29 as well as the remaining outstanding issues (ECE/TRANS/WP.29/2014/53, ECE/TRANS/WP.29/2014/82). GRB requested the secretariat to deliver, at its next session, a detailed presentation on Revision 3 of the 1958 Agreement. The Chair pointed out that Regulations Nos. 28, 51 and 117 under the responsibility of GRB had been recently amended and are ready for the inclusion in the IVWTA listing.
30. The secretariat reported on the highlights of the 164th session of WP.29 (ECE/TRANS/WP.29/1112, GRB-61-04).
31. Following the adoption of major amendments to several Regulations, GRB resumed its exchange of views on issues that should be included in the future work. The expert from France was of the view that GRB would be occupied with updating Regulation No. 28 (see para. 5 above). The expert from Germany pointed out that backing alarms for QRTV could cause problems at night and volunteered to prepare an informal document on this issue for the next session.
32. GRB was informed that Mr. Pieter Steenackers (CLEPA) would no longer attend its sessions. GRB thanked him for his contributions and wished him success in his new career.
33. The secretariat reported on best practices for using private standards in Regulations managed by WP.29 (WP.29-164-26).
34. The expert from IMMA informed GRB of his intention to submit, to the next session, proposals for amendments to Regulation No. 41 for hybrid vehicles. He invited GRB experts to provide comments, if any, before the next session.
35. For its sixty-second session, scheduled to be held in Geneva from 1 (starting at 2.30 p.m.) to 3 (concluding at 5.30 p.m.) September 2015, GRB noted that the deadline for the submission of official documents to the secretariat was 5 June 2015, twelve weeks prior to the session. The following provisional agenda was adopted:
1. Adoption of the agenda.
2. Regulation No. 28 (Audible warning devices).
3. Regulation No. 41 (Noise of motorcycles): Development.
4. Regulation No. 51 (Noise of M and N categories of vehicles):
(b) Additional sound emission provisions.
5. Regulation No. 59 (Replacement silencing systems).
6. Regulation No. 92 (Replacement exhaust silencing systems for motorcycles).
7. Regulation No. 117 (Tyre rolling noise and wet grip adhesion).
