10. GRSP considered ECE/TRANS/WP.29/GRSP/2011/12, GRSP-49-17 and GRSP-49-18 proposing a corrigendum to the gtr. The expert from OICA made a presentation (GRSP-49-31) justifying his proposal (GRSP-49-09) to clarify the headform test procedure. It was agreed to resume discussion on this agenda item at the December 2011 session of GRSP. The expert from the Netherlands volunteered to prepare a consolidated proposal of amendments (including ECE/TRANS/WP.29/GRSP/2011/12, GRSP-49-17, GRSP-49-18 and GRSP-49-09). He offered to submit it together with an official proposal of developing an amendment to the gtr for the November 2011 sessions of WP.29 and AC.3.
