Proposal to align UN R59 with recent amendments to UN R51.

10. The expert from CLEPA introduced GRB-54-09 proposing the inclusion of the additional sound emission provisions (ASEP) also into Regulation No. 59. The proposal received comments from GRB experts, such as the deletion of the proposed tolerance of 4 dB(A), unless technical rationales are provided for justification. GRB agreed to resume discussion at its February 2012 session on the basis of a revised proposal tabled by the expert from CLEPA.

Text prepared by the European Association of Automotive Suppliers (CLEPA) to introduce Additional Sound Emission Provisions (ASEP) into the UN R59.

13. The expert from CLEPA introduced ECE/TRANS/WP.29/GRB/2013/8 amended by GRB-58-05 and aimed at introducing ASEP provisions. The expert from the Russian Federation suggested that the text of the proposal should be aligned with the corresponding ASEP provisions of the 03 series of amendments to UN Regulation No. 51. GRB agreed to defer discussion on this subject to its January 2013 session awaiting a new official proposal at that session, aligned to a revised proposal on ASEP provisions of UN Regulation No. 51. It was also agreed to keep ECE/TRANS/WP.29/GRB/2013/8 and GRB-58-05 as references in the agenda of the next meeting.

15. In the absence of the expert from CLEPA, GRB agreed to defer discussion on this subject to its September 2014 session and to keep ECE/TRANS/WP.29/GRB/2013/8 and GRB-58-05 as references in the agenda of the next meeting, awaiting the outcome of discussion of the IWG on UN Regulations Nos. 51 and 59.
