4. The expert from the United Kingdom, Chair of the IWG on UN Global Technical Regulation (UN GTR) No. 7 Phase 2, informed GRSP about the work progress (GRSP-53-14) of his group. He added that the last meeting of the group had been held on 23-24 April 2013 in Paris and that two further WebEX meetings would be held before the summer to advance the drafting. He explained that as a result of its activities the group agreed on:

(a) An effective head restraint height measurement procedure whose thresholds for an absolute height would be returned to GRSP for final decision.

(b) An appropriate dynamic test, including the test procedure, injury criteria and the associated corridors for the Biofidelic Rear Impact Dummy (BioRID II).
