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 mixed by calculation with sound 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.
