43. The expert from AVERE introduced ECE/TRANS/WP.29/GRVA/2020/7 and ECE/TRANS/WP.29/GRVA/2020/8 (and their respective amendments in GRVA-05-08 and GRVA-05-24), proposing amendments to the ACSF provisions, resuming the discussion started in September 2019. He mentioned the support provided by the expert from the United Kingdom. The experts from Sweden and France provided comments. The experts from Denmark, Finland, the Netherlands and Norway expressed concerns. The expert from the Netherlands explained that the dynamics problems reported by the manufacturer, member of AVERE, were not due to the provisions in the Regulation but were due to design choices made by this manufacturer. The experts from the European Commission, Korea and United Kingdom and Northern Ireland supported the proposals; the expert from OICA, too. The expert from the Russian Federation proposed alternative proposals (GRVA-05-59) improving the text. The expert from the United Kingdom proposed GRVA-05-57 aimed at addressing the comments expressed by the expert from Sweden. GRVA reviewed all revised proposals produced by the expert from AVERE during the week but remained divided. GRVA agreed to review a revised proposal at the sixth session of GRVA, if time allows.

44. The Chair of GRVA noted the division of GRVA on this matter. He proposed that GRVA performs a general review of the Regulation at its September 2020 session.
