32. The Chair reported on the outcome of the informal meeting in Brussels on 31 October 2018 and introduced a revised document on priorities of the future work (GRB-69-03) with topics related to sound emission and tyre requirements. The document covered essentially the limit values for phase 3, ASEP, uncertainties, track alignment and measurement discrepancies, provisions for the so-called three peak mountain snow flake (3PMSF) winter tyres, wet grip test method for C1 tyres, wet grip for worn tyres, etc. The experts from China, Germany, Netherlands, EC, ETRTO and OICA commented on the proposal. The Chair indicated his intention to convene a meeting to develop a roadmap for level 1 priorities, as marked in GRB-69-03.

11. The expert of OICA raised the issue of uncertainties of sound emission measurements according to UN Regulation No. 51 and some other UN Regulations (GRB-69-15). He pointed out that the uncertainties included variations within the same test laboratory (run-to-run), variations in the ambient conditions and equipment properties (day-to-day) and variations between test laboratories and road surface conditions (site-to-site). The expert from ISO reported on field experience for measuring variations according to ISO 16254 (GRB-69-26). To reduce variations and improve repeatability and reproducibility of the results, he suggested that a single microphone should be replaced with an array of microphones.
12. The experts from Germany and France proposed to address non-negligible differences in sound performance when conformity of production (CoP) tests were not carried out in the same conditions as the type approval tests (GRB-69-05). The proposal introduced conditions and procedures to be followed for test tracks comparison and for corrections to be applied on Lurban. GRB welcomed this initiative as an important starting point for further work and invited GRB experts to support it with real data.
13. GRB stressed the importance of addressing measurement uncertainties and pointed out the need to establish a new task force to this end. While OICA volunteered to provide secretariat support to the task force, GRB was not in a position to identify a governmental expert who would take the lead, due to the limited resources of competent authorities. Nevertheless, GRB was of the view that the task force should start activities as soon as possible, even without a formal leader. GRB requested the ECE secretariat to establish a dedicated website for the task force and suggested that it should meet in conjunction with the meetings of other IWGs, in order to reduce the travel expenses of participants. GRB also invited its Chair to report to the Committee for Coordination of Work (WP.29/AC.2) on the issue.

Proposal to: - add a footnote to the scope to exempt electrified vehicles where the internal combustion engine (ICE) operates under the test conditions
- clarify the intention of paragraph 6.2.:
- that AVAS may be operational outside the specified speed ranges (e.g., in the USA where the speed range extends to 30 km/h),
- align maximum sound with UN R51.03 ASEP, and
- explicitly specify that the AVAS may function even when the ICE is running
- clarify under paragraph 6.2.6. that a manufacturer may install an attenuation to enable the system to operate at different sound levels
- split and clarify indoor and outdoor testing specifications under Annex 3 paragraph 2.2. to account for different needs such as a weather station
- amend the flowcharts in the Annex 3 Appendix to better reflect the regulation text.

GRB adopted the proposal, as laid down in Annex II and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2019 sessions as a draft Supplement 1 to the 01 series of amendments to UN Regulation No. 138.
18. The expert from OICA proposed to clarify the application of the 01 series of amendments to Regulation No. 138 (GRB-67-09). The experts from China, France, Germany, OICA and WBU commented on the proposal. The secretariat pointed out that it had already rectified the text of paragraph 6.2.6. which had been incorrectly reproduced in a revised consolidated version published on the WP.29 website (E/ECE/324/Rev.2/Add.137/Rev.1 − E/ECE/TRANS/505/Rev.2/Add.137/Rev.1). GRB invited OICA to take into account the comments received and to prepare an official document for consideration at the next session. GRB also requested that the earlier OICA proposals for transitional provisions (ECE/TRANS/WP.29/GRB/2017/7) be included into this new document.

The experts from France, Netherlands and Switzerland posed questions. The expert from UK requested data on the availability of EMT on the market. GRB was of the view that Contracting Parties needed more time to study the proposals and decided to defer this item to the next session. Meanwhile, GRB experts were invited to study the proposals and send their remarks to ETRTO.

21. The expert of France proposed a wet adhesion requirement for C1 tyres in a worn state (ECE/TRANS/WP.29/GRB/2019/6 and GRB-69-08). The proposal received comments from ETRTO (GRB-69-10). GRB also noted a recent study on used tyres (GRB-69-09). GRB was of the view that this topic should be pursued in the framework of a new IWG and adopted its Terms of Reference (GRB-69-23), as reproduced in Annex V to the session report. Various experts expressed their willingness to contribute to the activities of the newly established IWG. The experts from France and the European Commission volunteered to act as Chair and Co-Chair, respectively, while ETRTO agreed to provide secretariat support.

11. The expert of OICA raised the issue of uncertainties of sound emission measurements according to UN Regulation No. 51 and some other UN Regulations (GRB-69-15). He pointed out that the uncertainties included variations within the same test laboratory (run-to-run), variations in the ambient conditions and equipment properties (day-to-day) and variations between test laboratories and road surface conditions (site-to-site). The expert from ISO reported on field experience for measuring variations according to ISO 16254 (GRB-69-26). To reduce variations and improve repeatability and reproducibility of the results, he suggested that a single microphone should be replaced with an array of microphones.
12. The experts from Germany and France proposed to address non-negligible differences in sound performance when conformity of production (CoP) tests were not carried out in the same conditions as the type approval tests (GRB-69-05). The proposal introduced conditions and procedures to be followed for test tracks comparison and for corrections to be applied on Lurban. GRB welcomed this initiative as an important starting point for further work and invited GRB experts to support it with real data.
13. GRB stressed the importance of addressing measurement uncertainties and pointed out the need to establish a new task force to this end. While OICA volunteered to provide secretariat support to the task force, GRB was not in a position to identify a governmental expert who would take the lead, due to the limited resources of competent authorities. Nevertheless, GRB was of the view that the task force should start activities as soon as possible, even without a formal leader. GRB requested the ECE secretariat to establish a dedicated website for the task force and suggested that it should meet in conjunction with the meetings of other IWGs, in order to reduce the travel expenses of participants. GRB also invited its Chair to report to the Committee for Coordination of Work (WP.29/AC.2) on the issue.
26. On behalf of the Task Force on Reverse Warning (TF-RW), the expert from Japan reported on the progress of TF-RW (GRB-69-20). GRB pointed out the need to liaise with the Working Party on General Safety (GRSG) on the issue and was of the view that the TF-RW report should be also be brought to the attention of GRSG.
