GRB-65-03/Rev.1 | Proposal for amendments to the Consolidated Resolution on the Construction of Vehicles (R.E.3) (Russia)

26. The expert from the Russian Federation proposed to change the measuring units for vehicle masses from tonnes to kilograms in the Consolidated Resolution on the Construction of Vehicles (R.E.3, ECE/TRANS/WP.29/78/Rev.4) (GRB-65-03-Rev.1). GRB supported the proposal and requested the secretariat to circulate it to other WP.29 Working Parties, in particular, to Working Party on General Safety (GRSG) at its April 2017 session.

Working Party on Noise | Session 66 | 4-6 Sep 2017

1. The Working Party on Noise (GRB) held its sixty-sixth session from 4 to 6 September 2017 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): China; France; Germany; Hungary; India; Italy; Japan; Netherlands; Poland; Republic of Korea; Russian Federation; South Africa; Spain; Sweden; Switzerland and Turkey. Experts from the European Commission (EC) participated. Experts from the following non-governmental organizations also participated: European Association of Automotive Suppliers (CLEPA); European Tyre and Rim Technical Organization (ETRTO); International Council of Academies of Engineering and Technological Sciences (CAETS); International Motor Vehicle Inspection Committee (CITA), International Motorcycle Manufacturers Association (IMMA); International Organization for Standardization (ISO) and International Organization of Motor Vehicle Manufacturers (OICA).

2. GRB considered and adopted the agenda. The list of informal documents is contained in Annex I. The list of GRB informal groups is reproduced in Annex III.

4. The expert from IMMA proposed to delete the last sentence in paragraph 1.3.2.1., since the scope of the 04 series of amendments to Regulation No. 41 did not cover motorcycles with a sidecar (L4 category of vehicles) (ECE/TRANS/WP.29/GRB/2017/4). GRB adopted this proposal and requested the secretariat to submit it to the World Forum for Harmonization of Vehicle Regulations (WP.29) and to the Administrative Committee (AC.1) for consideration and vote at their March 2018 sessions as a draft Supplement 6 to the 04 series of amendments to Regulation No. 41.

5. The expert from EC introduced the ongoing study on Euro 5 sound level limits of L-category vehicles (GRB-66-15) with the aim to investigate the potential for new sound limits of L-category vehicles. He explained that the study takes into account the evolution of sound levels of road vehicles (actual vehicle testing), citizens’ needs and stakeholders interest (feedback gathering), and technical and economic feasibility in the medium term (cost-benefit analysis). The experts from Germany, Netherlands and OICA pointed out that only reducing the sound limits for new vehicles would not achieve the desired results unless accompanied by measures to combat illegal aftermarket products (silencers). The Chair proposed to resume this discussion once the results of the study would be available.

6. The expert from Germany highlighted the existing problems with and possible solutions for the noise emissions of L-category vehicles, including non-original replacement exhaust silencer systems (NORESS) (GRB-66-12). According to him, there was a gap between quiet vehicles during the type approval process and loud vehicles on the streets, because of manipulation with silencers, loopholes and grey areas in the United Nations and the European Union (EU) regulations. For better enforcement of compliance of vehicles in use with the sound limits and as an alternative to measurement of stationary noise, he proposed a simplified pass-by noise test which could be used for road-side checks and periodic technical inspections of type approved motorbikes and their NORESS (GRB-66-17). The experts from France and the Netherlands supported the need for stronger enforcement. The expert from IMMA volunteered to contribute to developing the pass-by noise test.

7. The expert from Japan presented an overview of the current noise regulations in Japan and their expected development in the future (GRB-66-08). In particular, he pointed out that Japan was reviewing the limit value for the acceleration noise of two-wheelers and hoped that these domestic considerations could be synchronized with the GRB deliberations on new limit values in the 04 series of amendments to Regulation No. 41.

8. On behalf of a group of experts, the expert from OICA proposed a number of amendments updating and revising the 03 series of amendments to Regulation No. 51 (ECE/TRANS/WP.29/GRB/2017/6). These proposals received comments from the experts of China, Russian Federation and Switzerland (GRB-66-11, GRB-66-13 and GRB-66-19). The expert from OICA also proposed some further modifications (GRB-66-20).

9. The expert from Italy expressed concerns about the suggested extension of the sound pressure level measurement to line BB’ plus 20 m, with the aim to properly assess the possible “backfire”. According to him, this modification would be a new requirement which should be introduced by means of a new series of amendments with transitional provisions, rather than by a supplement, as proposed in ECE/TRANS/WP.29/GRB/2017/6. He also pointed out that the above modification would need to be accompanied with a similar change in the relevant ISO standard. The experts from Germany, Japan, Sweden and Switzerland supported this amendment proposal in the form of a supplement. The expert of the Russian Federation supported the proposal as a supplement and agreed that Regulation No. 51 and the ISO standard should be aligned. The experts from France and EC were of the view that a new series of amendments would be more appropriate.

10. Given a large number of amendment proposals to Regulation No. 51, including the ones transmitted by the Informal Working Group (IWG) on Additional Sound Emission Provisions (ASEP) (see para. 12 below), GRB consolidated and provisionally adopted these proposals, as contained in Annex II. At the same time, GRB was not in a position to reach consensus on whether or not the adopted proposals would require a new series of amendments and/or transitional provisions. GRB decided to come back to this issue at its next session in January 2018. Meanwhile, the secretariat was requested to submit, in December 2017, the adopted text (Annex II) to WP.29 and AC.1 for consideration and vote at their March 2018 sessions as a draft Supplement 3 to the 03 series of amendments to Regulation No. 51, upon the understanding that any possible modifications, to be decided by GRB in January 2018, could exceptionally be submitted to WP.29 as a corrigendum or addendum to the original WP.29 document.

11. The expert from ISO proposed to introduce an option of indoor testing, according to standard ISO 362-3, in Annex 3 to Regulation No. 51 (ECE/TRANS/WP.29/GRB/2017/8). This proposal received comments from the experts of France, Netherlands, Poland, Spain, Sweden and OICA. GRB decided to revert to the proposals at the next session and invited all experts to study the document and to send their questions and comments to ISO.

12. The expert from China reported on noise problems and driving conditions in China in relation to the 03 series of amendments to Regulation No. 51 (GRB-66-21). In particular, he pointed out that further research would be needed to identify a relationship between the test cycles and noise problems as well as to develop a test method which would cover both the driving behaviours and noise issues. The Chair invited IWG ASEP to address these issues in cooperation with China.

3. No issues were considered under this agenda item.

13. On behalf of IWG ASEP, the expert from France presented its status report to GRB (GRB-66-14). In particular, IWG ASEP had agreed to propose some improvements in the current Annex 7 as soon as possible, as laid down in ECE/TRANS/WP.29/GRB/2017/5, and then to develop a more general and strategic approach of revising Annex 7. The expert from the Russian Federation commented on ECE/TRANS/WP.29/GRB/2017/5 (GRB-66-06). GRB agreed to merge these proposals with the other proposed amendments to the 03 series of amendments to Regulation No. 51 (see para. 9 above).

14. The expert from EC introduced draft amendments on powered cycles (GRB-66-09). GRB noted that these proposals would first be endorsed at the EU level and then officially submitted to the next session of GRB. The Chair invited experts to provide their comments to the expert from EC.

15. The expert from the Netherlands provided an overview of their research projects on tyres and proposed a two-stage tightening of the tyre limits for the rolling resistance coefficient, wet grip index and rolling sound emissions (GRB-66-01 and Add.1, GRB-66-03). He also highlighted the importance of keeping the correct tyre pressure for fuel efficiency and pointed out shortcomings of the EU system for labelling tyres.

16. The expert from ETRTO was of the view that the selections of tyres in the Dutch studies was not representative enough for the European market and volunteered to submit to the next GRB session a more comprehensive analysis. The expert from OICA supported the ETRTO view and proposal. He further introduced the results of a recent study of C1 summer tyres (GRB-66-22) according to which no tyre was performing equally well in rolling sound and handling. The expert from Germany acknowledged the progress achieved in rolling sound and pointed out the need to find a compromise for the three tyre parameters in question. He also agreed that the tyre labelling system would need to be improved.

17. The Chair was of the view that amending the limit values in Regulation No. 117 would first require a general agreement of all stakeholders, including the Working Party on Brakes and Running Gear (GRRF). Finally, GRB decided to continue the discussion at the next session.

18. The expert from EC reported on amending and supplementing the Acoustic Vehicle Alerting System (AVAS) requirements in Annex VIII to EU Regulation No. 540/2014, based on the provisions of Regulation No. 138 on Quiet Road Transport Vehicles (QRTV) and its 01 series of amendments (GRB-66-16).

19. GRB noted that the National Rule on Minimum Sound Requirements for Hybrid and Electric Vehicles in the United States of America came into force on 5 September 2017 and that the work of IWG QRTV GTR would resume shortly.

20. The expert from OICA proposed to slightly modify the wording of the transitional provisions introduced in the 01 series of amendments to Regulation No. 138 (ECE/TRANS/WP.29/GRB/2017/7). The Chair proposed to postpone consideration of this document until the adoption, at the November 2017 session of WP.29, of the Draft General Guidelines for United Nations regulatory procedures and transitional provisions in UN Regulations (ECE/TRANS/WP.29/2017/107) (see para. 30 below).

21. GRB recalled its previous discussions and decision to draft a new Regulation on reversing alarm (ECE/TRANS/WP.29/GRB/63, paras. 3 and 4). GRB reconsidered whether this work should be conducted in the framework of a new informal working group (GRB-66-07) or by means of a task force (TF) and agreed that TF would be sufficient. The expert from Japan volunteered to take the lead, while the experts of France, Germany, Netherlands, Republic of Korea, Turkey and EC (subject to availability of resources) declared their interest in taking part in the TF activities.

22. The expert from the Republic of Korea briefed GRB on the status of domestic accidents resulting from reversing vehicles (GRB-66-02). He concluded that M1 vehicles caused the largest number of backup collisions, while N1 and N2 vehicles caused the largest number of fatalities. The expert was of the view that all vehicles should be equipped with at least one safety device for moving backward, like rear view cameras, reversing alarms and parking sensors. The Chair pointed out that GRB should collaborate with the Working Party on General Safety Provisions (GRSG), which was conducting work on rear view cameras. The experts from Germany and OICA were of the view that reversing alarms should be installed on commercial vehicles, while M1 and N1 vehicles should be equipped either with rear view cameras or parking sensors.

23. No proposals were considered under this agenda item.

24. The expert from EC informed GRB about the EU activities that aim to prevent or reduce the effects of exposure to environmental noise harmful for health (GRB-66-18). According to the expert, this work is conducted in the framework of Directive 2002/49/EC which inter alia provides for a road vehicle (acoustic) classification and a road surface (acoustic) classification. To allow detailed discussions with member States and stakeholders on environmental noise policy issues, the EU Noise Expert Group (NEG) had been established. The expert wondered if there was space for exchange of information between GRB and NEG. The Chair was of the view that GRB and NEG should identify common elements for future cooperation.

25. The expert from the Netherlands presented a project on labelling road surfaces (GRB-66-05 and Add.1) based on the following criteria: skid resistance, noise reduction, rolling resistance and lifespan. He pointed out that labelling road surfaces could contribute to road safety, public health, sustainability and economies. GRB noted that the project mainly addressed passenger cars and that for trucks a solution would still be found.

26. GRB thanked the expert for the presentation and recalled its earlier considerations (ECE/TRANS/WP.29/GRB/63, para. 24) that labelling road surfaces could only be introduced as a non-legally binding document, such as a recommendation or resolution. The expert from the Netherlands wondered whether a new annex to the Consolidated Resolution on the Construction of Vehicles (R.E.3) could be an appropriate place for that purpose. GRB also noted that WP.29 and its other subsidiary bodies, like GRRF and GRSG, as well as the Working Party on Road Transport (SC.1) might be interested in pursuing the project and should be consulted. GRB invited its experts to send their contributions, if any, to the expert from the Netherlands and to develop for the next session clear ideas on how to proceed. In the interim, the Chair was requested to brief the Administrative Committee for the Coordination of Work (WP.29/AC.2) on the GRB considerations.

27. No issues were considered under this item.

28. GRB noted that the proposal to change the measuring units for vehicle masses from tonnes to kilograms (GRB-65-03-Rev.1), which was agreed on at the previous session, was submitted to the October 2017 session of GRSG (ECE/TRANS/WP.29/GRSG/2017/20).

29. GRB noted that Revision 3 of the 1958 Agreement (ECE/TRANS/WP.29/2016/2) would enter into force on 14 September 2017. The secretariat drew the attention of GRB to several novelties in Revision 3, in particular, a new numbering of type approvals, approval markings and their possible replacement by the Unique Identifier (UI), unless specified otherwise in a UN Regulation.

30. The secretariat also informed GRB about the recent activities of IWG on the International Whole Vehicle Type Approval (IWVTA) and that its final official draft had been submitted to the November 2017 session of WP.29 (ECE/TRANS/WP.29/2017/8). Questions and answers on IWVTA were issued as ECE/TRANS/WP.29/2017/9.

31. The secretariat reported on the highlights of the 171st and 172nd sessions of WP.29 (GRB-66-04).

32. No new information was presented under this agenda item.

34. The expert from EC proposed amendments to Regulation No. 9 with the aim to introduce ASEP requirements for L4 and L5 category vehicles with the power-to-mass ratio (PMR) of more than 50 W/kg (GRB-66-10). The Chair and the expert from Poland raised questions on referencing Global Technical Regulations (GTR) No. 15. The Chair also pointed out that the proposals should be accompanied with transitional provisions and invited the expert form EC to submit updated proposals to the next GRB session as an official document.

33. Upon the request of WP.29, GRB considered the Draft General Guidelines for United Nations regulatory procedures and transitional provisions in UN Regulations (ECE/TRANS/WP.29/2017/107) prepared by IWG IWVTA. The expert from OICA pinpointed provision 6.1 (in square brackets) which stipulated that “a Contracting Party may apply additional national provisions for vehicle characteristics not covered by the scope of a UN Regulation”. According the expert, this provision seemed to be counterproductive for the harmonization of vehicle Regulations and should be clarified. The Chair invited GRB experts to consider the Draft Guidelines and to submit their comments, if any, to the secretariat and/or to IWG IWVTA by 20 October 2017.

36. 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 for the year 2018.

35. For its sixty-seventh session, scheduled to be held in Geneva from 24 (starting at 2.30 p.m.) to 26 (concluding at 5.30 p.m.) January 2018, GRB decided to keep the same structure of the provisional agenda. GRB noted that the deadline for the submission of official documents to the secretariat would be 30 October 2017, twelve weeks prior to the session. The Chair also invited experts to submit informal documents well in advance before the session.
