Proposal for Supplement 1 to the 03 series of amendments to Regulation No. 51
Proposal for Supplement 1 to the 03 series of amendments to Regulation No. 51
Proposal to clarify the wording of the 03 series of amendments to UN R51 as adopted by the World Forum in June 2015 (document WP.29/2015/62). The adopted wording could lead to the interpretation that sound levels measured on the left side of the vehicle are to be averaged with levels measured on the right side of the vehicle. The proposed new wording clarifies that the overall sound emission is assessed individually per vehicle side.
This proposal (WP.29/2016/4) was adopted by the World Forum. Thirty-four Contracting Parties out of the 43 applying UN R51 were present for the vote by AC.1. Thirty-four voted in favor with zero against and zero abstaining.
