4.6.2. | Proposal for Supplement 3 to the 01 series of amendments to UN Regulation No. 138 (Quiet road transport vehicles)

1st TFQRTV session (20 May 2022)

74th GRBP session (15-17 Sep 2021)

6. | UN Regulation No. 138 (Quiet road transport vehicles)

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.
