12. GRBP agreed to postpone consideration of ECE/TRANS/WP.29/GRBP/2019/7 to the next session.

14. The expert from ETRTO recalled the postponed proposal for amendments (ECE/TRANS/WP.29/GRVA/2018/5 and GRB-68-12) and presented complementary modifications (ECE/TRANS/WP.29/GRBP/2019/19, GRBP-70-21-Rev.2). Various experts posed clarifying questions, in particular, on the use of terms “repeatability” and “reproducibility”. Following an in-depth discussion, GRBP adopted the proposals, as amended by Annex III, and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their March 2020 sessions as a draft Supplement 11 to the 02 series of amendments to UN Regulation No. 117.

17. The expert from BIPAVER presented a proposal that aligns the provisions for retreaded tyres marked with the three-peak-mountain snow-flake (3PMSF) symbol with the previously adopted amendment proposals to UN Regulation No. 117 (ECE/TRANS/WP.29/GRBP/2020/5). GRBP adopted the document and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2020 sessions as part of Supplement 10 to UN Regulation No. 109.
