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. |
