GRBP | Session 74 | 15-17 Sep 2021

21. The expert of ETRTO tabled draft amendments that introduced an “ice grip tyre” definition and editorial corrections (ECE/TRANS/WP.29/GRBP/2021/17). GRBP adopted the proposal, as amended by GRBP-74-31-Rev.1, and requested the secretariat to submit it for consideration and vote at the March 2022 sessions of WP.29 and AC.1 as draft Supplement 14 to the 02 series of amendments to UN Regulation No. 117.

23. The expert from France, in her capacity of Co-Chair IWG WGWT, presented draft amendments that introduced a procedure and thresholds on wet grip performance for C1 tyres in worn state (ECE/TRANS/WP.29/GRBP/2021/12, as updated by GRBP-74-33-Rev.1). GRBP adopted GRBP-74-33-Rev.1 and requested the secretariat to submit it for consideration and vote at the March 2022 sessions of WP.29 and AC.1 as a new draft 03 series of amendments to UN Regulation No. 117. GRBP noted that, with the aim to complete the proposal and remove few square brackets, an informal document would be prepared for the next session. If adopted, this document would also be submitted to the March 2022 sessions of WP.29 and AC.1. GRBP noted that, to avoid possible uncertainty, the adopted draft Supplement 14 to the 02 series of amendments (see para. 21 above) would be explicitly included in the future WP.29 document with the new draft 03 series of amendments to UN Regulation No. 117.
