98. The representative of Japan reported on the work progress (WP.29-161-19) of the IWG on UN GTR No. 7 Phase 2. The representative of the United Kingdom, chairing the group, informed AC.3 that the injury criteria for the use of the Biofidelic Rear Impact Dummy (BioRID II) were still pending due to constraints of medical research in the United States of America. Nevertheless, he reported that his group had made good progress in drafting the UN GTR for consideration at the December 2013 session of GRSP. He added that the draft UN GTR would be supplemented with an addendum to the Mutual Resolution No. 1 (M.R.1) that could also be useful as a model for future addenda developed by other IWGs. He finally suggested that a complete discussion of the proposals would take place during the 2014 sessions of GRSP, leaving Contracting Parties with a final decision concerning the removal of the current Hybrid III dummy from the dynamic test.
