Session 64 | Geneva | 5-7 Sep 2016
4. Regulation No. 51 (Noise of M and N categories of vehicles)
4. (a) Regulation No. 51: Development
WP.29/2016/4 | 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.
4. (b) UN Regulation No. 51: Additional sound emission provisions
GRB-64-04 | Proposals to clarify the provisions of Regulation No. 51, Revision 3, Annex 7 Proposal to clarify the text in order to avoid misinterpretation.
GRB-64-23 | Draft Terms of Reference for the informal working group on Additional Sound Emission Provisions Objectives and procedures for an informal working group to further develop Annex 7 and otherwise improve UN R51.
GRB-64-16 | Information on Additional Sound Emission Provisions
GRB-64-23/Rev.1 | Revised draft Terms of Reference for the informal working group on Additional Sound Emission Provisions
9. Exchange of information on national and international requirements on noise levels
GRB-64-24 | Implementation of the 03 series of amendments to Regulation No. 51 in China
