100. The expert from Italy presented GRVA-11-35, introducing ECE/TRANS/WP.29/GRVA/2021/28 and ECE/TRANS/WP.29/GRVA/2021/29. He explained that Annex 15 was leading to a high number of groups to be tested and therefore was inducing an overproportioned test workload due to the grouping criteria. 101. GRVA adopted ECE/TRANS/WP.29/GRVA/2021/28 and requested the secretariat to submit it as draft supplement to UN Regulation No. 90 to WP.29 and AC.1 for consideration and vote at their March 2022 sessions. 102. The expert from the United Kingdom of Great Britain and Northern Ireland questioned the relevance of the amendments proposed in Table 1 in ECE/TRANS/WP.29/GRVA/2021/29. The expert from Italy volunteered to provide more details for review at the next session. 103. GRVA agreed to resume discussion on ECE/TRANS/WP.29/GRVA/2021/29 at its twelfth session. |
