10. The expert from Australia, Chair of the IWG on Pole Side Impact (PSI), introduced ECE/TRANS/WP.29/GRSP/2013/7 and GRSP-53-05, superseding ECE/TRANS/WP.29/GRSP/2013/2, as the official draft UN GTR proposed by his group. He also introduced the final progress report of the group (GRSP-53-04-Rev.1). The proposal received some comments such as GRSP-53-13, tabled by the expert from the United States and GRSP-53-19 by the expert from France. Moreover, the American expert raised a study reservation on the seating procedure for the World Side Impact 50th percentile male test dummy (WorldSID) (paras. 5.6 to 5.13 of Annex 2 of the text of the Regulation). GRSP also noted that a parallel proposal to the M.R.1 to introduce the WorldSID would be submitted at a later stage to GRSP and to WP.29 for adoption. It was agreed as a provisional solution to refer drawings and specifications of the dummy to the pertaining International Standard Organization (ISO) website. (http://standards.iso.org/iso/15830). Accordingly, it was agreed to seek guidance at the June 2013 session of WP.29/AC.2 on this subject. GRSP considered GRSP-53-23 consolidating all the changes agreed upon the discussion.
