125. The representative of Australia, chairing the informal working group on PSI, presented the second progress report of the group (WP.29-156-29).

126. He clarified that this report sought a change in the terms of reference of the informal working group to allow for a second phase of work on the world side impact dummy (WorldSID) 5th percentile female. He reported that this change was endorsed by GRSP at its December 2011 session. He stated that the informal working group had not met since he reported on its activities at the November 2011 session of AC.3. However, he announced that the fifth meeting of the informal working group would be held on 22-23 March in London (see para. 113), focusing on a revised draft UN GTR in detail, with the aim of submitting an initial draft to the May 2012 session of GRSP. He added that several presentations would be made during the meeting, including further crash tests undertaken
by a number of countries. He specified that the Monash University Accident Research Centre (MUARC) would give a presentation of its research, including on injury types, effectiveness of different airbag combinations and the benefits of a regulation. He clarified that, while pole side impacts were not as common as other crashes, they were frequently lethal. He said that MUARC’s work also revealed that injuries in pole side impacts involved very high societal costs frequently involving serious head injuries. He reported that a final first phase UN GTR would be presented to WP.29 and AC.3 for consideration and vote at their June 2013 sessions. He concluded that the sixth meeting of the informal working group was scheduled in the week before the June 2012 session of WP.29 in Munich.

127. The representative of The United States of America supported the revised terms of references for a two stage approach for developing the UN GTR to address the widest range of vehicle occupants.

128. AC.3 endorsed, in principle, the revised terms of references of the informal working group (see para. 32) and requested the secretariat to distribute WP.29-156-29 with an official symbol.
