30. GRSP considered the informal evaluation of the ad hoc group of experts of the technical merits of study from Sweden on female occupants. The expert from Sweden explained that the ad hoc group was trying to have a better identification and understanding of the problem, therefore she proposed the establishment of an informal working group and provided terms of reference in GRSP-70-01. The expert from the United States of America informed GRSP that she had participated in only the first meeting of the ad hoc group because the ad hoc group had not complied with the mandate given by WP.29 (ECE/TRANS/WP.29/1159, paras. 22 and 58), i.e., collect and review data to determine if there is a merit to Sweden’s claim. GRSP agreed that the ad hoc group of experts could continue to review existing research/share ongoing research and if GRSP determines that there is enough evidence to address this issue, an IWG may be established.
