3. The expert from IMMA presented draft amendments that introduce a mandatory test for Additional Sound Emission Provisions (ASEP) and correct an inconsistency in the ASEP exemption conditions for vehicles with variable gear ratios or automatic transmission with non-lockable gear ratios (ECE/TRANS/WP.29/GRBP/2019/22 and ECE/TRANS/WP.29/GRBP/2019/23). GRBP adopted both proposals and requested the secretariat to submit them to WP.29 and to the Administrative Committee (AC.1) for consideration and vote at their March 2020 sessions as a draft Supplement 1 to the 08 series of amendments to UN Regulation No. 9.
