4.9. | Consideration of draft amendments to existing UN Regulations submitted by GRBP

102. For agenda item 4.9.1. (ECE/TRANS/WP.29/2023/71), WP.29 called upon the type approval authorities and technical services to start collecting and transmitting data on the Real Driving Additional Sound Emission Provisions (RD-ASEP) as from the previously agreed date 1 July 2023.

4.9.1. | Proposal for Supplement 9 to the 03 series of amendments to UN Regulation No. 51 (Noise of M and N categories of vehicles)

4.6.1. | Proposal for Supplement 8 to 03 series of amendments to UN Regulation No. 51 (Noise of M and N categories of vehicles)

3. | UN Regulation No. 51 (Noise of M and N categories of vehicles)

8. GRBP recalled that, on 1 July 2023, a one-year monitoring period would start for collecting and analysing test data on the Real Driving Additional Sound Emission Provisions (RD ASEP). The expert from OICA presented their views on the organization of this process (GRBP-77-14) and proposed a draft monitoring data sheet for the purposes of RD ASEP data collection (GRBP-77-15-Rev.1). GRBP noted that the Technical Services, under overall responsibility of the Type Approval Authorities, should play a key role in gathering the required data sets and sending them not less than every three months to an independent contractor selected by OICA, who would check the quality and analyse the data. OICA invited Contracting Parties to inform OICA by the end of February 2023, if they would be willing to financially contribute to the project.

9. To clarify the process of data collection, the experts from Germany and OICA proposed amendments to UN Regulation No. 51 (GRBP-77-13-Rev.1). GRBP adopted the proposal and requested the secretariat to submit it for consideration and vote at the June 2023 sessions of WP.29 and AC.1 as draft Supplement 9 to the 03 series of amendments to UN Regulation No. 51. GRBP also requested the secretariat to publish on the GRBP website, the final version of the monitoring data sheet (currently GRBP-77-15-Rev.1) which would be available in May 2023.

10. GRBP noted that the above amendments, if approved in June 2023, would enter into force around January 2024, while the data collection should start on 1 July 2023. GRBP counted on the cooperation of Contracting Parties and urged Type Approval Authorities and Technical Services to collect and transmit the RD ASEP data as of 1 July 2023. GRBP also invited WP.29, at its June 2023 session, to reiterate this request to Contracting Parties.

11. In view of the forthcoming RD ASEP monitoring, GRBP agreed to resume the activities of IWG ASEP and to extend its mandate until December 2024. At its next session, GRBP decided to review the Terms of Reference of IWG ASEP and invited experts to prepare proposals.
