9. The Chair of GRSP, on behalf of the Chair of the IWG Mr. D. Sutula, informed GRSP that the IWG had not yet met to discuss the next steps, but would like to do so before making any decisions. To that end, he informed GRSP that the Chair of the IWG would apprise WP.29 and AC.3 during the March 2018 session of the extension of the mandate of the IWG and how the group would move forward.

10. The expert from OICA introduced GRSP-62-09 aimed at updating the reference of the ISO standard concerning the World Side Impact Dummy (WorldSID) fiftieth percentile in Addendum 2 of Mutual Resolution No. 1 (M.R.1). He urged GRSP to adopt the amendment to prevent disruption in type approval testing. The expert from Australia supported the proposal as the only viable solution to quickly solve the issue. The expert from Germany informed GRSP about the intention of his country to inform WP.29 about the current status of the M.R.1. He solicited that the addenda of the M.R.1, such as those incorporating anthropomorphic test devices (crash test dummies) and the World Side Impact Dummy fiftieth percentile specifications, be completed as soon as possible. He therefore urged the establishment of an advisory group of experts from research institutes, test laboratories, dummy manufacturers and experts from the industry under the aegis of GRSP to regularly update M.R.1. The expert from CLEPA made a similar statement (GRSP-62-34) urging the completion of M.R.1 of specific descriptions of crash test dummies which were essential for the correct application of UN Regulations and GTRs. GRSP finally adopted GRSP-62-09, as reproduced in Annex III to this report and requested the secretariat to submit it as draft Amendment 1 to Addendum 2 to M.R.1 for consideration and vote at the March 2018 sessions of WP.29 and AC.3 (ECE/TRANS/WP.29/2018/36).
