1. The Working Party on Noise and Tyres (GRBP) held its eightieth session from 17 to 20 September 2024 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/Rev.2): Canada, China, Czechia, Finland, France, Germany, Hungary, India, Italy, Japan, Netherlands, Norway, Poland, Republic of Korea, Russian Federation, Spain, Sweden, Switzerland and United Kingdom of Great Britain and Northern Ireland. Experts from the European Commission participated. Experts from the following intergovernmental organization participated: Gulf Cooperation Council Standardization Organization (GSO). Experts from the following non-governmental organizations also participated: American Automotive Policy Council (AAPC), Bureau International Permanent des Associations de Vendeurs et Rechapeurs de pneumatiques (BIPAVER), European Tyre and Rim Technical Organization (ETRTO), Imported Tyre Manufacturers Association (ITMA), International Motorcycle Manufacturers Association (IMMA), International Organization for Standardization (ISO), International Organization of Motor Vehicle Manufacturers (OICA), Pew Environment Group and World Blind Union (WBU).

2. GRBP considered and adopted the agenda (ECE/TRANS/WP.29/GRBP/2024/18, as amended by GRBP-80-01). GRBP noted the running order proposed by the Chair (GRBP-80-15-Rev.1). The informal documents are listed in annex I. The GRBP informal groups are given in annex II.

3. The expert from the Informal Working Group on Real Driving – Additional Sound Emission Provisions (IWG RD-ASEP) introduced draft amendments that clarified interpretation issues in the 05 series of amendments to UN Regulation No. 41, such as the number of test points, riding modes and speed tolerances (GRBP-80-08). GRBP noted that IWG RD – ASEP solicited comments on the draft amendments with a view to updating the proposal and submitting it as a working document to the next session.

GRBP-80-08 | UN R41: Proposal for a Supplement to the 05 series of amendments Proposal prepared by the experts from the IWG RD-ASEP in order to clarify the application of the Annex 7 ASEP testing conditions of motorcycles.

4. The expert of IWG RD-ASEP also reported on their progress on drafting a new 06 series of amendments to UN Regulation No. 41, including the limit line concept and remaining issues (GRBP-80-09). GRBP noted that a working document with the draft 06 series of amendments would be submitted to the next session.

GRBP-80-09 | UN R41: Presentation by IWG RD-ASEP on proposal for amendment for a new 06 Series of amendments

5. GRBP was briefed on the activities IWG RD – ASEP (GRBP-80-04).

GRBP-80-04 | UN R51: IWG ASEP Status report IWG RD-ASEP has two parts: A) RD-ASEP for UN-R51, to develop a mandatory procedure after the monitoring phase B) RD-ASEP for UN-R41: ASEP second step, to develop stricter ASEP limit curves

6. The expert from OICA reported on the ongoing ASEP/ RD-ASEP study (GRBP-80-31) which included two parts:

1. their own tests of eight vehicles (four pairs of old and successor models) according to the 02 and 03 series of amendments to UN Regulation No. 51, ASEP and partly RD-ASEP, and
2. an analysis of data on RD-ASEP collected from the type approval authorities and technical services under the monitoring phase according to the 03 series of amendments to UN Regulation No. 51.

7. Regarding (ii), the expert of OICA explained that the collected data might not be representative enough, due to the low number of datasets the majority of which had been received from two type approval authorities. Thus, he wondered whether the current mandatory RD-ASEP testing period could be extended with the aim to cover more vehicles and powertrain technologies.

8. GRBP noted that the legally established monitoring period had ended in June 2024 and that further data should be collected until the end of December 2024 only on a voluntary basis. GRBP also agreed that OICA should contact the type approval authorities to find out the number of vehicle manufacturers whose test data had been submitted anonymously.

9. The expert from the Informal Working Group on Measurement Uncertainties (IWG MU) presented a revised document for reference (GRBP-80-07-Rev.1) replacing ECE/TRANS/WP.29/GRBP/2024/8 considered at the previous session. The experts from the Netherlands, Switzerland, United Kingdom and EC expressed concerns over possible misinterpretation of the purpose and content of the document, in particular the suggested 3.5 dB(A) margin and the last sentence in paragraph 1.1.1. In the absence of a consensus, the Chair proposed to keep the document on the agenda of the next session as a working document.

GRBP-80-07/Rev.1 | Reference document: Measurement Uncertainties when testing This document for reference might be applied to measurement procedures used in UN regulations of the Working Party on Noise and Tyres (GRBP). It supports the definition of limit values during the development of regulations by transparently presenting the measurement uncertainties embodied in the measurement procedures during type approval, conformity of production and other measurement reasons. Replaces GRBP/2024/08

GRBP/2024/8 | Measurement uncertainties when testing in UN Regulations under the purview of GRBP Proposal from the Measurement Uncertainties informal group for a Document for Reference providing a general approach on how to handle measurement uncertainties in UN Regulations (initially addressing UN Regulations Nos. 51 and 117).

10. The expert of OICA proposed a regulatory package for the sound emission limits of electric vehicles (EVs) equipped with Exterior Sound Enhancement Systems (ESES) (ECE/TRANS/WP.29/GRBP/2024/22, GRBP-80-20-Rev.1 and GRBP-80-21-Rev.1). The expert of EC introduced a counter proposal (GRBP-80-12 and GRBP-80-23), including an alternative definition of Exterior Sound Producing and Amplifying System (ESPAS) in lieu of ESES. According to her, for EVs the emission of additional exterior sound is only acceptable as long as it addresses safety concerns and should be strictly prohibited whenever safety is not at stake, as in the case of ESPAS or ESES. In addition, she proposed to include EVs in the scope of ASEP, in order to reap the full benefits of switching to EVs in terms of noise emission. In reply, the expert from OICA pointed out that in many situations AVAS was not sufficient for road safety (for example, in the vicinity of schools) and that ESES could play a role in those situations. He also mentioned that there seemed to be a market demand for ESES from some drivers who otherwise would not buy EVs.

11. The expert from Switzerland pointed out that there was no easy way to determine a worst-case situation with regard to ESES. For this reason, he supported the EC proposal rather than the OICA one, but acknowledged the fact that all parties in GRBP share the objective of addressing this issue.

12. The expert from the Netherlands expected a positive effect of the increasing number of EVs on noise reduction, particularly in cities at urban speeds, being the key consideration for the Netherlands. According to him, prohibiting ESES, as suggested by EC, seemed to be the most certain solution to secure the EV noise reduction benefits at this moment. He was also mindful of other influencing factors.

13. The expert from France stated that, to combat noise pollution for the well-being of the society, it would be impossible for the Government to justify adding unnecessary noise to EVs. The expert from the United Kingdom stated that he would need more time to study the proposals in combination with draft amendments to UN Regulation No. 138 (see paras. 18-21 below). The experts from Germany and Japan pointed out that any prohibition of ESPAS (ESES) should be done with caution and suggested that this topic be discussed further in a new subgroup (group of interest) and then by IWG RD-ASEP.

14. The expert from OICA volunteered to act as Secretary, should a new subgroup be established. The experts from Switzerland and EC indicated their interest in co-chairing the new subgroup, subject to approval of their management. GRBP welcomed these statements and noted that the new subgroup could kick off in conjunction with the meetings of IWG RD-ASEP and GRBP Task Forces (TF) in October 2024 (see para. 45 below). In the interim, GRBP invited all experts to send their comments to the experts from EC and OICA without delay, with a view to preparing a working document for the next session.

GRBP-80-20/Rev.1 | UN R138: Background to proposal for the Application of Noise Limits to EVs fitted with Exterior Sound Enhancement Systems (ESES) Gives the background to proposal for the Application of Noise Limits to EVs fitted with Exterior Sound Enhancement Systems (ESES) to UN R51

GRBP-80-21/Rev.1 | UN R51: Proposal for a Supplement 12 to the 03 series of amendments The text reproduced below was prepared by the experts from OICA in order to address the original intent of the Task Force on Quiet Road Transport Vehicles (TF QRTV). This proposes to expand the speed range of ASEP forBEVs down to speeds > 0 km/h.

15. GRBP recalled the adopted guidelines on antitampering provisions for Non-Original Replacement Exhaust Systems (NORESS) and considered a proposal of a special interest group that integrated the guidelines into the legal text of UN Regulation No. 92 (ECE/TRANS/WP.29/GRBP/2024/21). In the course of an in-depth discussion, GRBP came to the conclusion that this proposal would require a new series of amendments. GRBP adopted the proposal, as amended by GRBP-80-29-Rev.3, and requested the secretariat to submit it for consideration and vote at the March 2025 sessions of WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) as draft 03 series of amendments to UN Regulation No. 92.

GRBP/2024/21 | UN R92: Proposal for a Supplement 1 to the 02 series of amendments Proposal to clarify the requirements for non-original replacement exhaust silencing systems (NORESS).

16. The expert from Japan proposed clarifications (ECE/TRANS/WP.29/GRBP/2024/20 and GRBP-80-33) which were based on the considerations of the former Task Force on Quiet Road Transport Vehicles (TF QRTV). GRBP adopted the proposal and requested the secretariat to submit them for consideration and vote at the March 2025 sessions of WP.29 and AC.1 as Supplement 1 to the 02 series of amendments to UN Regulation No. 138.

17. The experts from WBU and OICA presented the outcome of their joint events in Aachen (June 2024) and in Neuburg (August 2024), which tested external vehicle sound and assessed situations where electric vehicles equipped with an acoustic vehicle alerting system (AVAS) might be overheard (GRBP-80-32), and replied to clarifying questions.

18. The expert from EC introduced a proposal for a new 03 series of amendments to UN Regulation No. 138 (GRBP-80-06 and GRBP-80-24). According to her, the proposal contained improvement both in terms of safety (mandatory AVAS sound up to 30 km/h, increase in the minimum sound levels at low speed) and in terms of environmental noise (prohibition of AVAS sound above 30 km/h, decrease in the maximum sound levels in standstill, forward and reverse). Finally, she invited GRBP experts to provide feedback in September-October 2024, with the aim to incorporate comments and improvements and to submit a working document to the next session of GRBP.

19. The experts from France, Germany, Japan, Netherlands, United Kingdom, OICA and WBU expressed their interest in participating in further discussions on the topic. Given the proposed significant changes, some experts requested more time to study the proposal. The expert from Japan sought scientific evidence for the proposal. The expert from Italy pointed out the need of a cost/benefit analysis of environmental aspects.

GRBP-80-24 | UN R138: Proposal for amendment for the sensitive fixation of the AVAS sound pressure levels EC resulting position to • limit the emission of AVAS to what is strictly necessary for safety • corollary: prohibit unnecessary noise

20. The expert of OICA introduced draft amendments to the 02 series of amendments to UN Regulation No. 138 (GRBP-80-28), which took into account a new definition of “Exterior Sound Enhancement System” (ESES) proposed for UN Regulation No. 51 in ECE/TRANS/WP.29/GRBP/2024/22 submitted by OICA. According to OICA, UN Regulation No. 138 should remain a safety UN Regulation while the environmental concerns should be addressed by UN Regulation No. 51. GRBP noted that the two Regulations provide parallel specifications for an overlapping speed range (20 – 50 km/h).

21. Given the complexity of the problem and lack of time, GRBP was not in a position to take a decision on the proposals by the experts of EC and OICA. To make progress, the Chair suggested that the proposals be first considered within a new group of interest before GRBP would revert to them at the next session. GRBP agreed that discussions could first start in October 2024 in the framework of the new subgroup on UN Regulation No. 51 (see para. 14 above) with a later establishment of a separate subgroup on UN Regulation No. 138, if necessary.

22. The expert from EC proposed to delete a footnote in UN Regulation No. 138 stating that, at this stage, only acoustic measures should be developed in order to overcome the concern of reduced audible signals from electrified vehicles and that alternative, non-acoustic measures, should only be developed later by the respective Working Parties (GRs) (GRBP-80-13). According to her, other GRs should be requested to develop such alternative measures as soon as possible, given the serious public health concerns due to vehicle noise. The Chair replied that he would convey this request to WP.29 and that, for the time being, deleting of the footnote seemed to be premature.

GRBP-80-13 | UN R138: Proposal for alternative non-acoustic measures to AVAS Proposal to delete this footnote 2 from the regulation

23. The expert of ETRTO spotted a mistake in the French text of UN Regulation No. 75 (GRBP-80-02). GRBP noted that the secretariat had already contacted the UNOG translation services who would re-issue the French version.

GRBP-80-02 | UN R75: Proposal for corrigendum (to the French version) Correction to the French version of the document which had a missing text in Annex 5 Table 7.

24. The expert from ETRTO proposed a correction to the 01 series of amendments to UN Regulation No. 108 (Retreaded tyres for passenger cars and their trailers) (ECE/TRANS/WP.29/GRBP/2024/24). GRBP adopted the correction as a Supplement to both the 00 and 01 series of amendments but agreed to postpone its submission to WP.29 and AC.1 in view of another forthcoming amendment proposal to the same UN Regulation which would be submitted by ETRTO to the next session.

GRBP/2024/24 | UN R108: Proposal for a Supplement to the 01 series of amendments Proposal to correct an omission and clarify the text of Annex 3: The positioning and order of <b>the markings shall be as follows:</b>....

25. GRBP was briefed on the activities of the IWG on Wet Grip Performance of Tyres in Worn State (IWG WGWT) (GRBP-80-34).

GRBP-80-34 | UN R117: Status report by IWG Wet Grip on Worn Tyres

26. The expert of IWG WGWT proposed improving the precision of the test method for C1 tyres (ECE/TRANS/WP.29/GRBP/2024/23, GRBP-80-11 and GRBP-80-30). GRBP adopted the proposal, as amended by GRBP-80-11 and requested the secretariat to submit them for consideration and vote at the June 2025 sessions of WP.29 and AC.1 as draft Supplement 3 to the 04 series of amendments to UN Regulation No. 117. Should GRBP adopt another draft amendment to the same series of amendments at its session in February 2025, it would be combined with the above proposal.

GRBP-80-11 | UN R117: Proposal for Supplement 3 to the 04 series of amendments Proposal by the IWG WGWT to replace document ECE/TRANS/WP.29/GRBP/2024/23. This proposal aims as a first step to standardize the water depth measurement.

GRBP/2024/23 | UN R117: Proposal for a Supplement 3 to the 04 series of amendments Proposal from the Wet Grip on Worn Tyres informal group to standardize provisions for the water depth measurement and to reduce the track friction range requirements under the test procedures.

27. The expert from ETRTO referred to their document with corrections to the 04 series of amendments to UN Regulation No. 117 (ECE/TRANS/WP.29/GRBP/2024/25) and requested to postpone its consideration, due to comments received from the experts of France, Netherlands and United Kingdom. GRBP agreed with this request and encouraged other experts to provide their comments as well.

GRBP/2024/25 | UN R117: Proposal for a Supplement to the 04 series of amendments Proposal to clarify that wet adhesion provisions apply to C1, C2, and C3 tyres, correct ISO and internal references, clarify symbols "ARC" and "ARR" relationships to indoor drum test method, and clarify application to M+S marked tyres.

28. The expert from AAPC recalled that, at the previous session, they had presented the proposal in ECE/TRANS/WP.29/GRBP/2024/17 that allowed, under certain conditions and weight limits, the use of LT-marked tyres with a rolling resistance greater than the current limits in UN Regulation No. 117. Following comments by the experts from France, Italy, Netherlands, Switzerland and United Kingdom, GRBP was not in a position to support the proposal and indicated that such exemptions should be granted at the national or regional levels. Taking into account the GRBP views, the expert from AAPC agreed to withdraw the document and to pursue the issue at the regional level.

GRBP/2024/17 | UN R117: Proposal to amend the 02, 03 and 04 series of amendments Proposal to allow the use of LT-marked tyres under certain conditions and weight limits with a rolling resistance greater than the current limits.

29. The expert of ETRTO shared their concerns over the recent evolution of UN Regulation No. 117 which was becoming increasingly complex by regular additions of new requirements, annexes and series of amendments with transitional provisions (GRBP-80-25). To avoid further complexity with the upcoming introduction of tyre abrasion requirements, he proposed several options, including splitting the Regulation into several ones. To consider various options in detail, he argued for the establishment of a Group of Interested Experts (GOIE) with a task to develop a conceptual informal document for consideration and validation at the next session in February 2025, to be followed by a working document in September 2025. GRBP agreed with this proposal. Many experts volunteered to participate in GOIE.

GRBP-80-25 | UN R117: Presentation on the Evolution of the regulation ETRTO recommends to create a GRBP GOIE (Group of Interested Experts) involving CP’s and NGO’s and with the goal to present an Informal Document by GRBP February 2025 session to validate the concept to be followed and implemented in a Working Document by September 2025

30. The expert from the Russian Federation introduced a revised proposal that clarified certain provisions (ECE/TRANS/WP.29/GRBP/2024/19). GRBP adopted the proposal and requested the secretariat to submit it for consideration and vote at the March 2025 sessions of WP.29 and AC.1 as draft Supplement 4 to the 00 series of amendments to UN Regulation No. 124. During the adoption, the expert from the Netherlands reserved his position.

GRBP/2024/19 | UN R124: Proposal for a Supplement Proposal to clarify the text:<ul><li>clarify Annex 4 and exclude aluminum-alloy and magnesium-alloy wheels under test (b)</li><li>clarify Annex 6 with regard to possible defects caused by the production process and not affecting the appearance of cracks during testing</li><li>recommend under Annex 6 to identify cracks occurred as a result of the test by using penetrating paints</li><li>clarify Annexes 7 and 8 with regard to air leakage.</li></ul>

31. The expert from the United Kingdom, Co-Chair of the Task Force on Tyre Abrasion (TF TA), reported on their progress (GRBP-80-22). He explained that TF TA was conducting market assessment for developing future limits for tyre abrasion based on the two adopted test methods, namely the outdoor road circuit method and the indoor drum method. To ensure proper multi-circuit and multi-drum correlation, GRBP encouraged additional test centres to join the assessment campaign.

GRBP-80-22 | TF Tyre Abrasion: status report

32. GRBP was informed that, at the June 2024 session of WP.29, the representative of the Russian Federation had presented WP.29-193-10 on the establishment of limits for emissions of carcinogenic substances from tyres and had suggested that TF TA should explore the possibility of introducing limits for such substances (polycyclic aromatic hydrocarbons – PAH) in tyre production compounds. WP.29 had requested GRBP to consider the issue and to report back to WP.29.

33. The expert from the Russian Federation introduced the results of their research on the carcinogenicity of tyres and rubbers (GRBP-80-10-Rev.1). The expert pointed out that PAH emissions are associated with tyre wear and therefore suggested that TF TA should develop regulatory provisions for carcinogenic safety of tyres. He added that standard ISO 21461 could be used for testing tyres as a finished product and that a limit for overall carcinogenicity of tyres could be included in UN Regulation No. 117.

34. The expert from the United Kingdom, Co-Chair of TF TA, pointed out that TF TA did not have expertise in this field and, in addition, was engrossed with their mandated work. He also believed that the Working Party on Pollution and Energy (GRPE) would be more appropriate to tackle the issue. The expert from EC recalled the EU Regulation on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), which inter alia applies to tyres, and did not see the need for another regulation in this area at the UN level. The expert from ETRTO stated that the members of their organization are committed to REACH and questioned the expertise and competence of WP.29 and its subsidiary Working Parties (GRs) in the area of chemicals. He also pointed out that the issue of carcinogenic substances should be addressed at the national level and that double regulation (both at national and UN levels) should be avoided.

35. The Chair concluded that neither GRBP nor TF TA had the necessary expertise and that GRPE seemed to be the only GR which might be competent. The Chair would convey this message to WP.29 at its next session in November 2024.

36. The expert from Germany proposed aligning UN Regulation No. 142 with the provisions of UN Regulation No. 54 concerning the installation of free rolling tyres (GRBP-80-03). The expert from ETRTO suggested further amendments (GRBP-80-26). GRBP invited both parties to rediscuss the topic with the aim to submit an official document to the next session.

GRBP-80-03 | UN R142: Proposal for a Supplement 2 to the 01 series of amendments Proposal to clarify that FRT tyres shall not be fitted to front steering and drive axles of motor vehicles.

GRBP-80-26 | UN R142: Proposal for a Supplement 2 to the 01 series of amendments The proposal provides a more clear indication by introducing the definition of “Front axle” so that it clarifies the interpretation of front steering axle.

37. GRBP took note of the Task Force on Vehicle Sound (TF VS) status report (GRBP-80-27).

41. The Chair presented a revised list of priorities (GRBP-80-14) and invited all experts to provide comments with the aim to update the document accordingly. As a new topic, the expert from France suggested development of a sound signal to announce the arrival of an electric public transport vehicle (e.g. bus) at a bus stop. Some experts supported this idea, while some others pointed out that such a signal could disturb people around. GRBP agreed to continue the discussion at the next session.

42. The expert from the Task Force on Automated Vehicles Regulation Screening (TF AVRS) briefed GRBP on their activities (GRBP-80-16) and introduced their revised guidelines (GRBP-80-17) which GRBP adopted. The expert also briefly presented draft amendment proposals to UN Regulations Nos. 28 and 138 to make their requirements fit to automated vehicles (GRBP-80-18 and GRBP-80-19). GRBP noted the progress of TF AVRS would depend on a set of definitions that should be developed by GRVA and its subgroups.

44. Due to lack of time, GRBP agreed to postpone to the next session the following issues:

• the WP.29 request to its subsidiary Working Parties to identify UN Regulations under their purview which may be relevant for the purposes of software updates; and
• an update on the activities of the OICA internal task force on exterior acoustic signalling.

45. The expert from OICA informed GRBP about a draft running order and tentative timetable of the forthcoming meetings of various IWGs and TFs on 28 – 31 October 2024 in Berlin (GRBP-80-35-Rev.2). The expert from Japan announced the schedule for IWG and TF meetings under GRBP on 9-12 December 2024 in Japan (GRBP-80-36)

46. GRBP noted that Mr. J. Makino (Japan), due to his retirement, would no longer participate in GRBP. GRBP thanked him for his contributions and wished them success in the future.

47. For its eightieth session, scheduled to be held in Geneva from 18 to 21 February 2025, GRBP decided to keep the same structure for the provisional agenda, subject to the inclusion of a separate agenda item the activities of TF AVRS. GRBP noted that the deadline for the submission of official documents to the secretariat would be 25 November 2024, twelve weeks prior to the session.

48. In compliance with Rule 37 of the WP.29 Rules of Procedure (ECE/TRANS/WP.29/690/Rev.2) and Rule 42 of the ECE Rules of Procedure (E/ECE/778/Rev.5), GRBP re-elected by acclamation Mr. S. Ficheux (France) as Chair and Mr. B. Schüttler (Germany) as Vice-Chair for the year 2025.
