GRBP | Session 74 | 15-17 Sep 2021

12. The expert from France introduced a proposal that aimed to clarify the interpretation of the requirements concerning the variation of the sound emitted proportionally with the vehicle speed (ECE/TRANS/WP.29/GRBP/2021/14). She also proposed to clarify the testing requirements (GRBP-74-05). GRBP supported in principle these proposals, subject to replacement in GRBP-74-05, paragraph 6.2.3.2. of “≥” with “greater or equal to”, but in view of other ongoing activities on UN Regulation No. 138 decided to await further amendment proposals with the aim to combine them into a single package before submitting to WP.29 and AC.1.
