140. The representative of the United Kingdom, Chair of the IWG on Phase 2 of UN GTR No. 7 on head restraints, informed AC.3 that his group had suspended its activities and had not been able to establish injury criteria directly from post-mortem subject testing due to the lack of research outcomes. However, he announced that the group intended to re-start its activity after the summer break and to submit an official proposal of amendments, based on empirical data, to the UN GTR and a parallel one to UN Regulation No. 17 at the December 2018 session of GRSP. He added that such proposals would be eventually complemented by: (a) an informal document to introduce the latest development of the IWG on injury criteria, (b) the final status report of the IWG, and © a proposal of Addendum 1 to the Mutual Resolution No. 1 to incorporate drawings and specifications of the Bio Rear Impact Dummy. He concluded that the IWG is expected to finalize this work within one year of activity and therefore requested an extension of the mandate. 

141. AC.3 endorsed the request of extension of the mandate until June 2019.
