116. The representative of the United Kingdom, Chair of the IWG on Phase 2 of UN GTR No. 7, informed AC.3 about the ongoing progress of his Group. He reported that, while good progress had been made on the performance of the anthropometric test device (ATD), more work was required to develop the correlation between the human and the ATD response in order to establish pass/fail criteria. He agreed to provide an official report to the June 2015 session of AC.3. He noted the good cooperation between the IWG and the ATD manufacturer in developing the complimentary entry to Mutual Resolution 1 (M.R.1). He confirmed that the proposal for Addendum 1 to M.R.1 would be provided in parallel with the proposal for Amendment 1 to UN GTR No. 7.
