Proposal to update certain Standard Reference Test Tyre (SRTT) denominations, to remove the distinction between the two Class C3 tyres, to clarify the text and remove the reference to tyres “not marked with speed symbol”. This document will be handled by GRB during its 68th session and is referenced under GRVA due to the “conversion” of GRRF.
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.
30. The expert from ETRTO introduced draft amendments to UN Regulation No. 117 (ECE/TRANS/WP.29/GRVA/2018/5 and GRB-68-12). The proposal received comments from the experts of Germany, Spain, United States of America and BIPAVER. The Chair invited other experts to transmit their remarks to ETRTO with a view to submitting a revised consolidated proposal to the next session.
