4. The expert from the Republic of Korea, Chair of the Informal Working Group on Deployable Pedestrian Protection Systems (IWG DPPS), introduced the final progress report of the group (GRSP-73-13-Rev.1). He introduced ECE/TRANS/WP.29/2023/6 and GRSP-73-12-Rev.1 as the final proposal for Amendment 3 to the UN GTR. The expert from Austria, on behalf of IWG, explained that the proposal incorporated a numerical test as a prerequisite to the certification test of vehicle bonnets. She noted that GRSP-73-59, explained the numerical simulation concerning the Head Impact Time (HIT), based on Generic Vehicle Models (GVM). GRSP continued discussion on HIT and GVM under agenda item 19 (paragraph 46).

5. GRSP agreed that the final draft of Amendment 3 needed further discussion within IWG. Thus, GRSP agreed to seek endorsement from the Executive Committee of the 1998 Agreement (AC.3) to extend the IWG mandate until May 2024. GRSP agreed to resume discussion at its December 2023 session based on a revised: (a) consolidated text of the amendments (superseding ECE/TRANS/WP.29/2023/6 and GRSP-73-12-Rev.1), (b) final report of IWG DPPS (superseding GRSP-73-13-Rev.1).
