He recalled that the draft 01 series of amendments would still be addressed by WP.29 this week (ECE/TRANS/WP.29/2021/10) and encouraged the World Forum to consider instead a revised consolidated proposal ECE/TRANS/WP.29/2021/10/Rev.1 under agenda item 4.6.9. 50. He also pointed out that GRBP had agreed to update the Terms of Reference of its two IWGs on Measurement Uncertainties (MU) and on Wet Grip Performance for Tyres in a Worn State (WGWT). WP.29 noted that the revised Terms of Reference were annexed to the report of GRBP at its seventy-third session. 51. WP.29 endorsed the updates of the Terms of Reference of the IWG MU and IWG WGWT. 78.
