Proposal to clarify that the maximum sound pressure requirement at the front plane at standstill condition in reverse shall be equal to the maximum level requirement in motion (defined by the QRTV task force as 75 dB(A) for both standstill and reverse driving).
16. The expert from Japan proposed clarifications (ECE/TRANS/WP.29/GRBP/2024/20 and GRBP-80-33) which were based on the considerations of the former Task Force on Quiet Road Transport Vehicles (TF QRTV). GRBP adopted the proposal and requested the secretariat to submit them for consideration and vote at the March 2025 sessions of WP.29 and AC.1 as Supplement 1 to the 02 series of amendments to UN Regulation No. 138.
