GRB | Session 69 | 23-25 Jan 2019

6. The Chair of the Informal Working Group on Additional Sound Emission Provisions (IWG ASEP) proposed to introduce transitional provisions for Supplements 4 and 5 to the 03 series of amendments to UN Regulation No. 51 (ECE/TRANS/WP.29/GRB/2019/9 and ECE/TRANS/WP.29/GRB/2019/11). GRB adopted these proposals and recalled that Supplement 5 would still be considered by WP.29 at its session in March 2019 (ECE/TRANS/WP.29/2019/4). To speed up the amendment process, GRB requested the secretariat to issue a revised version of ECE/TRANS/WP.29/2019/4 with the adopted transitional provisions.
