40. The representative of the United Kingdom introduced document ECE/TRANS/WP.29/GRVA/2026/30, aimed at clarifying that the Certificates of Conformity issued under UN Regulations Nos. 155 and 156 and the corresponding type approvals should be issued by the same Type Approval Authority. The representative of OICA, also speaking on behalf of CLEPA and CLCCR, presented their views on the practical difficulties arising from the requirement for a single Approval Authority to issue both the Certificate of Conformity and the type approval (GRVA-26-20). They proposed amendments to the 1958 Agreement regarding the voluntary acceptance of Certificates of Conformity (GRVA-26-21). Following discussion, GRVA adopted GRVA-26-35.

41. GRVA adopted ECE/TRANS/WP.29/GRVA/2026/30, as amended by Annex VII to this report (based on GRVA-26-35), and requested the secretariat to submit it as draft Supplement 4 to UN Regulation No. 155 and draft Supplements 2 and 1 to the original version and the 01 series of amendments to UN Regulation No. 156, respectively, to WP.29 and AC.1 for consideration and vote at their March 2027 sessions.
