100. The representative of the United States of America informed AC.3 about the ongoing activity of the informal group focused on the development of harmonized provisions of the fifth female and fiftieth male percentile world side impact dummy (WorldSID). She clarified that, for the time being, this activity was complementary to the proposal to develop a gtr on pole side test. According to the suggestion provided during WP.29/AC.2, she added that the activity of the informal group could cover in the future all the dummies used as tools in the gtrs and in the Regulations. AC.3 agreed to mandate the informal group to develop this matter under the chairmanship of the United States of America and leave this item under the exchange of views of the agenda for its forthcoming sessions as well as its reference document (ECE/TRANS/WP.29/2010/82).
