35. GRSP considered a proposal (GRSP-67-19-Rev.1) tabled by the experts from Japan to amend the definition of REESS (see paragraphs 16, 18 19 and 25). GRSP adopted the proposal, as reproduced by Annex X to the session report. The secretariat was requested to submit the proposal as draft Supplement 1 to the original version of the new UN Regulation (ECE/TRANS/WP.29/2020/76) on the approval of vehicles with regard to fuel system integrity and safety of electric power train in the event of a rear-end collision, for consideration and vote at the November 2020 sessions of WP.29 and AC.1. However, the Chair of GRSP was requested to seek guidance from WP.29 to recommend the above Supplement as binding from the date of its adoption by AC.1, in advance of its entry into force, in order to have a consistent application of the UN Regulation by all contracting parties to the Agreement.

63. The World Forum noted that GRSP recommended proposal for Supplement 1 to UN Regulation No. 153 (Fuel system integrity and safety of electric power train in the event of a rear-end collision) as binding from its establishment, in order to have a consistent application of the UN Regulation by all contracting parties to the Agreement. Finally, WP.29 recommended that all Contracting Parties to the 1958 Agreement agree to consider Supplement 1 to UN Regulation No. 153 (ECE/TRANS/WP.29/2020/114) when issuing type approvals.
