VPSD recommendations (GRPE/2015/13 & GRPE-71-xyz) and other definitions were reviewed by Bill Coleman:

• Proposed change of mass of optional equipment was supported by NL. Japan will scrutinize the proposal.
• ACEA proposal for gtr amendment (WLTP-11-27e) based on data of representative fuel tanks levels was discussed by IWG. CP’s and Stakeholder were asked to scrutinize the proposal. NL objected to reopen the mass definition and the mixing of mass in running order and reference mass definitions. EC could support the general idea of reducing the unrepresentative 90% tank filling provision, but objected to solve this by deleting 25 kg from the test mass. IWG decided not to put this issue on the agenda of IWG #12, unless a further developed proposal is supported by CPs in advance.
• IWG will expect position of GRPE on VPSD recommendations before amending gtr 15 definitions. SG Drafting will provide proposal for GTR 15 amendments for IWG #12.
