33. The expert from France, Chair of the Frontal Impact IWG, introduced ECE/TRANS/WP.29/GRSP/2015/11 as the final draft UN Regulation on frontal impact with focus on the restraint system, with a thorax compression criterion (ThCC) of 42 mm. He also introduced ECE/TRANS/WP.29/GRSP/2015/12, amended by GRSP-57-01 to require ThCC limit at 34 mm in the 01 series of amendments to the UN Regulation. The expert from Japan suggested also aligning the provisions of the draft UN Regulation with the new Camera-Monitor Systems provisions of UN Regulation No. 46 (see para. 27 above). GRSP noted also the lack of availability of drawings and specification of the 5th percentile female dummy and agreed to insert a footnote as a reminder to interested parties to provide the above mentioned specifications in time for adoption of the draft UN Regulation by WP.29 and AC.1. GRSP considered GRSP-57-29-Rev.1, amending ECE/TRANS/WP.29/GRSP/2015/11 and incorporating all the comments received during the discussion (including GRSP-57-02). Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2015/11 and ECE/TRANS/WP.29/GRSP/2015/12, both as amended by Annex V to this report. The secretariat was requested to submit for consideration and vote to WP.29 and AC.1 at their November 2015 sessions:
(i) ECE/TRANS/WP.29/GRSP/2015/11 as new draft UN Regulation on frontal impact with focus on the restraint system and
(ii) ECE/TRANS/WP.29/GRSP/2015/12 as 01 series of amendments to the new UN Regulation.

The expert from France introduced GRSP-57-31, for information only, to provide further justification of the biomechanical chest deflection thresholds introduced in the draft UN Regulation.
