1. The Working Party on Noise (GRB) held its fifty-sixth session from 3 (afternoon) to 5 (afternoon) September 2012 in Geneva. The meeting was chaired by Mr. Ch. Theis (Germany). 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 and Amend.1): Belgium; Brazil; Czech Republic; China; France; Germany; Hungary; India; Italy; Japan; Netherlands; Norway; Poland; Republic of Korea; 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).

2. GRB considered and adopted the agenda ECE/TRANS/WP.29/GRB/2012/4 and its Add.1 including new agenda items 15(a), 15(b), 17 and 18.

GRB/2012/4 | Annotated provisional agenda for the 56th GRB session Draft agenda for the September 2012 session of the Working Party on Noise.

GRB/2012/4/Add.1 | Addendum to the annotated provisional agenda for the 56th GRB session

3. GRB noted ECE/TRANS/WP.29/GRB/2012/5, tabled by the expert from the Russian Federation, to provide harmonized definitions on vehicle type concerning noise, the terms noise and sound. The expert from IMMA expressed a reservation (GRB-56-08) on the proposal as a whole arguing that the introduction of new definitions would be premature, taking into account the recent publication of Revision 2 of UN Regulation No. 41. GRB agreed to resume consideration on this proposal at its February 2013 session on the basis of further information provided by the expert from the Russian Federation.

4. GRB considered GRB-56-04, introduced by the expert from ISO, updating the text concerning the test site of the UN Regulation with the latest amendment of ISO Standard 5130:2012. The proposal received comments from the expert by Germany who suggested more objective criteria in verifying the level of porosity of the test site. GRB agreed to resume consideration on this subject on the basis of a revised proposal voluntarily prepared by the expert from ISO.

5. The expert from IMMA sought GRB’s clarification on paragraph 8.2. on the conformity of production tests, specifically: whether the 1 dBA allowance was applicable to the maximum A-weighted sound pressure level representing urban driving (L_urban) and to the sound pressure level in wide open throttle (L_wot). GRB agreed that currently paragraph 6.2.3. (specification regarding sound levels) clearly stated that the difference between L_wot shall not exceed the limit value for L_urban by more than 5 dB and if the +1dB was applied to L_urban, as given in Annex 6, then this additional +1 dB allowance was automatically also applicable to L_wot value.

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".

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/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.

6. See also, para. 20, concerning the updating of the requirements on the noise test track from ISO 10844:1994 to ISO 10844:2011, GRB agreed to defer discussion on ECE/TRANS/WP.29/GRB/2012/16 and ECE/TRANS/WP.29/GRB/2012/17 to its February 2013 session.

7. The expert from OICA introduced ECE/TRANS/WP.29/GRB/2012/8, consolidating a proposal of 03 series of amendments to UN Regulation No. 51. The proposal received comments from the expert of ETRTO (GRB-56-16) proposing to change the vehicle test conditions of Annex 10 of UN Regulation No. 51. GRB noted that the proposed changes (GRB-56-16) have already been adopted as Supplement 8 to the 02 series of amendments and agreed to amend ECE/TRANS/WP.29/GRB/2012/8 accordingly. Moreover, the expert from the Netherlands introduced GRB-56-12 proposing a new layout for the communication form. GRB agreed to resume consideration at its February 2013 session on ECE/TRANS/WP.29/GRB/2012/8 on the basis of a revised document prepared by the expert from the Netherlands in cooperation with the experts from CLEPA and OICA. GRB recommended experts to provide detailed comments.

8. GRB considered and adopted GRB-56-03 as reproduced in Annex II to this report, amending the figure for measuring positions of vehicles in motion. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2013 session as Supplement 9 to the 02 series of amendments to UN Regulation No. 51.

9. Finally GRB considered GRB-56-06, tabled by the expert from China, introducing amendments to the test method. He introduced GRB-56-09 for information, showing the difference among the test methods in UN Regulation No. 51, ISO 362 and the Chinese standard (GBI1495-2002) and GRB-56-22 as a justification to the proposed amendments to the test. The expert from OICA suggested that such relevant outcome of research should be brought together with those from other Contracting Parties to the 1958 Agreement (i.e. European Union) to keep UN Regulation No. 51 relevant worldwide. GRB agreed to resume discussion at the February 2013 session on a possible official proposal (based on GRB-56-06) tabled by the expert from China in cooperation with the expert from ISO.

GRB-56-03 | Proposal for Supplement 8 to the 02 series of amendments to Regulation No. 51 This proposal aligns Figure 2 (Reference Point) in the Appendix to Annex 3 of UN R51 with the latest amendment of ISO 5130:2012 and with the draft 04 series of amendments to Regulation No.41 (ECE/TRANS/WP.29/GRB/2011/3).

GRB-56-12 | Proposal for amendments to the proposal for the 03 series of amendments to Regulation No. 51 Document GRB/2012/08 from OICA proposes a text for the 03 series of amendments to UN R51 intended to consolidate the GRB discussions as of the 55th session. The Netherlands proposes further improvements in order to incorporate the latest relevant ISO standards and to simplify the communication.

10. The EC expert informed GRB on the work progress of the European Union (EU) institutions on the EC proposal on vehicle noise. He added that at this stage no political agreement on new limits had been reached at the EU level.

11. The expert from China introduced GRB-56-07, proposing a different scheme to identify vehicle categories. He also added that his proposal would offer an option to cover needs of a broader range of countries. The experts from Japan and OICA endorsed the Power to Mass Ratio index (PMR) as a tool to link noise emission and vehicle performance. The EC expert recalled that to overcome the different national political priorities/classifications, the discussion should be focused on the mutual recognition principle of the 1958 Agreement, i.e. the vehicle complying with the lowest noise level would be accepted everywhere. He recalled that this would not prevent Contracting Parties from having less stringent requirements in their national law for their internal markets. Finally GRB agreed to resume consideration of GRB-56-07 at its February 2013 session to provide study time for experts.

12. GRB considered GRB-56-01 and GRB-56-05 supplementing ECE/TRANS/WP.29/GRB/2012/7 tabled by the expert from Japan. He explained that the proposal was based on GRB-55-01, including limit values with some modification of the threshold of subcategories, as a basis for a common position with the proposal tabled by the expert from Germany (GRB-54-03). Moreover, he made a presentation (GRB-56-21) concerning rationales for the proposed Stage 3 of limit values. The EC expert stated that the review of vehicle classification should not only consider the proposals tabled by the experts from Germany and Japan, but also the present vehicle classification in UN Regulation No. 51 and in the EC proposal and verify the rationales for the changes proposed by the experts from Germany and Japan.

GRB recalled that the EC proposal was available at: http://ec.europa.eu/enterprise/sectors/automotive/documents/proposals/index_en.htm#h2-1

13. Upon the suggestion of the Chair, GRB agreed to verify data and provide a basis for analysis for a power reference value of 160 kW in vehicle category M3 and for the reference value of 140 kW in vehicle category N2. Finally, GRB agreed to resume consideration on this subject at its February 2013 session on the basis of the above test data, if available, and on those existing provided by the experts from China, Japan and EC.

15. The expert from CLEPA introduced GRB-56-17 listing further test results of four vehicles performed by his organization on additional sound emission provisions (ASEP) of replacement silencing systems. GRB noted that as an outcome of the test, two possible alternatives were possible to introduce ASEP provisions into UN Regulation No. 59: (i) the test should be carried out back to back to the original equipment and replacement system (ii) the manufacturer of the replacement system should perform the test with the same acceptance criteria as for the original equipment. GRB, in principle, agreed to follow option (ii) and to resume consideration on this subject at its February 2013 session on the basis of a concrete proposal tabled by the expert from CLEPA.

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

17. Referring to the report of the Working Party on Brakes and Running Gear (GRRF) (see ECE/TRANS/WP.29/GRRF/72, paras. 25 and 32-34), GRB considered ECE/TRANS/WP.29/2012/54 and ECE/TRANS/WP.29/2011/55, proposing to add specific performance requirements for C2 snow tyres and amending the definition of the measuring rim for C1, C2 and C3 tyres. GRB endorsed ECE/TRANS/WP.29/2012/55 without amendment, scheduled to be considered by WP.29 and AC.1 at their November 2012 sessions. Concerning ECE/TRANS/WP.29/2012/54, GRB considered GRB-56-15 tabled by the expert from Germany, proposing to introduce the inscription “M+S” or “M.S” or “M&S” only in combination with the “Alpine” symbol on a mandatory basis, if the tyre be classified as a “snow tyre for use in severe snow conditions”. Accordingly, GRB endorsed ECE/TRANS/WP.29/2012/54, as amended by Annex III to this report and agreed to submit it to WP.29 and AC.1, for consideration at their November 2012 sessions as draft Supplement 2 to the 02 series of amendments, subject to a final review by GRRF at its September 2012 session.

18. The expert from ETRTO introduced ECE/TRANS/WP.29/GRB/2012/10 aligning the text of Annex 6 of the UN Regulation to ISO Standard 28580. GRB adopted the proposal not amended and agreed to submit it to WP.29 and AC.1, for consideration at their March 2013 session as draft Supplement 3 to the 02 series of amendments to UN Regulation No. 117, also subject to a final review by GRRF at its September 2012 session (see ECE/TRANS/WP.29/GRRF/2012/18).

19. The expert from ETRTO proposed to amend the snow test method for C3 tyres (ECE/TRANS/WP.29/GRB/2012/11). However, GRB argued that some of the proposed amendments could conflict with the recommended introduction of blocking differential on driven axle as increasing repeatability in the test. GRB agreed to resume consideration of the proposal at its next session on the basis of an official document submitted to the March 2013 sessions of WP.29 and AC.1, incorporating possible changes (see ECE/TRANS/WP.29/GRRF/2012/19) agreed by GRRF at its September 2012 session.

20. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRB/2012/15 and ECE/TRANS/WP.29/GRB/2012/18 updating the test track provisions to ISO 10844:2011. The expert from ETRTO introduced similar amendments (ECE/TRANS/WP.29/GRB/2012/9) but without transitional provisions. GRB agreed that the introduction of new provisions for the test track should refer to a new series of amendments of the UN Regulation. Following the suggestion of the Chair and Vice-Chair, GRB considered GRB-56-20 (superseding ECE/TRANS/WP.29/GRB/2012/15, ECE/TRANS/WP.29/GRB/2012/18 and ECE/TRANS/WP.29/GRB/2012/9) drafted in accordance with ECE/TRANS/WP.29/1044/Rev.1 “Guidelines on the scope, administrative provisions and alternative requirements in Regulations annexed to the 1958 Agreement”. GRB requested the secretariat to distribute GRB-56-20 with an official symbol at its February 2013 session and agreed to refer to it as a basis to continue discussion on this subject.

21. Finally, GRB considered GRB-56-02 tabled by the expert from the Russian Federation aimed at providing detailed elaboration of the concept of tyre deceleration (dω/dt) in the test technology. The secretariat was requested to distribute it with an official symbol at its February 2013 session, pending the clarification of the reference to the “deceleration calculator” mentioned in the proposal.

GRB-56-02 | Proposal for Supplement 3 to the 02 series of amendments to Regulation No. 117 Proposal to improve accuracy in the calculation of tire rolling resistance by the deceleration method.
