21. The expert of IWG WGWT proposed to add the missing references for the molded standard reference test tyre (SRTT16) in the 03 and 04 series of amendments to UN Regulation No. 117 (ECE/TRANS/WP.29/GRBP/2023/2 and ECE/TRANS/WP.29/GRBP/2023/3). GRBP endorsed these references and noted that they had been already included in ECE/TRANS/WP.29/2023/5 and ECE/TRANS/WP.29/2023/8 which would be considered by WP.29 and AC.1 at their forthcoming session in March 2023. 23. The expert from ETRTO proposed a correction (ECE/TRANS/WP.29/GRBP/2023/8). GRBP adopted the correction and requested the secretariat to submit it for consideration and vote at the June 2023 sessions of WP.29 and AC.1 as part of draft Supplement 1 to the 04 series of amendments to UN Regulation No. 117. |
