82. The representative of the Russian Federation presented WP.29-190-21, providing evidence of the need for additional checks of complete vehicles during rollover tests within the framework of UN Regulation No. 66 (Strength of superstructure (buses)). He added that guidance was needed (WP.29-190-10) from the World Forum, since the proposal to GRSG asking for these additional checks had not been supported by the group (ECE/TRANS/WP.29/GRSG/104 para. 16) in March 2023. The representatives from France and South Africa shared the concerns of the representative of the Russian Federation and encouraged the production of a revised proposal to the October session of GRSG. The Chair of WP.29, as well as Chair of GRSG, clarified that initial proposal tabled for the 125th session of GRSG had not been supported because of lack of consistency with the principle of mutual recognition of type approval of the 1958 Agreement. The World Forum invited the representative of the Russian Federation to submit an updated proposal, providing more consistency with the above-mentioned principles for the October 2023 session of GRSG.
