The 124th GRSG session is scheduled to be held in Geneva from 11 October (9.30 a.m. CET) to 14 October (12.30 p.m.) 2022. The deadline for the submission of official documents to the secretariat is 19 July 2022, twelve weeks prior to the session.
20. GRSG considered documents prepared by the Task Force on UN Regulation No 110: (a) ECE/TRANS/WP.29/GRSG/2022/23 that introduces the minimum opening set pressure of the primary Liquid Natural Gas (LNG) relief valve, (b) ECE/TRANS/WP.29/GRSG/2022/24 and (c) ECE/TRANS/WP.29/GRSG/2022/25 that updates the existing requirements for CNG/LNG fuelled components. The expert from OICA proposed that the three documents be combined together as a new series of amendments. Therefore, he introduced GRSG-124-31-Rev.1, consolidating the three proposals and amending ECE/TRANS/WP.29/GRSG/2022/24. GRSG adopted ECE/TRANS/WP.29/GRSG/2022/23, ECE/TRANS/WP.29/GRSG/2022/24 and ECE/TRANS/WP.29/GRSG/2022/25 as amended by annex II to the session report. The secretariat was requested to submit the combined document of the three proposals as the 06 series of amendments to UN Regulation No. 110 for consideration and vote at the March 2023 sessions of AC.1 and WP.29.
21. GRSG considered GRSG-124-32, tabled by NGVA Europe to accept the type approvals according to the preceding series when not affected by the provisions of the new series of amendments. GRSG acknowledged the need to be consistent throughout all the series of amendments to the UN Regulation, and adopted GRSG-124-32 as reproduced in annex II to the session report. The secretariat was requested to submit the proposal as draft Supplement 4 to the 04 series of amendments to UN Regulation No. 110, for consideration and vote at the June 2023 sessions of WP.29 and AC.1. At the same time, it was agreed to keep the official proposal to WP.29 in the agenda of the March 2023 session of GRSG for possible further development.
