4. The expert from Germany reiterated his intention to find a solution (GRSP-65-17) to represent worst case scenarios, due to, for example, different heights of the vehicle from adjustable suspension systems. He also indicated that a concrete proposal had been submitted under agenda item 11 on UN Regulation No. 127. GRSP agreed to defer discussion to its December 2020 session, pending consideration of the Executive Committee of the 1998 Agreement (AC.3) at its November 2020 session.

5. Referring to the AC.3 decision at its March 2020 session (see ECE/TRANS/WP.29/1151, para. 158), GRSP reiterated its intention to finalise the work on harmonizing UN GTR No. 9 with UN Regulation No. 127, which already incorporates the proposed Amendment 3 to the UN GTR for the headform test (ECE/TRANS/WP.29/GRSP/2014/5 as amended by GRSP-67-13). However, the expert from the United States of America suggested that, due to the postponement of this current GRSP session from May to July, AC.3 had not received the results of the discussions and should first be informed of the process at its next session in November 2020 before vote on the proposed Amendment 3 at its March 2021 session.

Therefore, GRSP recommended: (a) Amendment 3 to UN GTR No. 9 (ECE/TRANS/WP.29/GRSP/2014/5), as amended by Annex II to the session report, (b) the final progress report (ECE/TRANS/WP.29/GRSP/2012/2) as amended by Annex II to the session report and (c) the authorization to develop the work (ECE/TRANS/WP.29/AC.3/31), for consideration and vote at the March 2021 sessions of WP.29 and AC.3.
