7. The expert from Germany, co-Chair of the informal working group on pedestrian safety introduced the third progress report of the group (GRSP-52-31), the updated terms of references (ToR) and operating principles of the informal working group (GRSP-52-32) and a first draft UN GTR for information purposes only (GRSP-52-33). GRSP endorsed the third status report of the informal working group (GRSP-52-31), adopted its new terms of reference (GRSP-52-32) as reproduced in Annex II to this report and agreed to seek endorsement from WP.29 and from the Executive Committee of the 1998 Agreement (AC.3) at their March 2013 sessions.

7. The expert from Germany, co-Chair of the IWG on pedestrian safety introduced the draft UN GTR No. 9 Phase 2 (GRSP-54-33) to incorporate the flexible pedestrian legform impactor (FlexPLI), as a result of the last meeting of the IWG held on 16 and 17 December 2013, prior to the GRSP proper session. He explained that the proposal superseded ECE/TRANS/WP.29/GRSP/2011/13, ECE/TRANS/WP.29/GRSP/2013/25 and GRSP-54-08, leaving pending the issues of the Injury Assessment Reference Values (IARVs) for the flexible lower legform to bumper test (para. 5.1.1) and for the tolerance of the FlexPLI mass (paras. 6.3.1.1. and 6.3.1.1.3.). The proposal received comments from the expert of the United States of America (GRSP-54-32) who questioned the lack of information concerning the above-mentioned IARVs. He stated that the draft UN GTR could not be recommended unless Contracting Parties would be allowed to choose appropriate IARVs when transposing the UN GTR into their national legislations. In response, the expert from Germany introduced GRSP-54-33-Rev.2 addressing this concern. The expert from OICA regretted the lack of agreement on this last issue which would result in a number of options, thus hampering harmonization.

8. The expert from Germany, co-Chair of the IWG on pedestrian safety introduced the fourth progress report of the group (GRSP-53-28) and announced a first draft UN GTR (GRSP-53-29), published on GRSP website for information only after the session of GRSP. He added that the group had made good progress and that it was ready to submit an official proposal to the December session of GRSP with possible pending decisions on threshold values of injury criteria. GRSP agreed to resume consideration of this subject on the basis of a proposal submitted by the IWG.
