51. The expert from Germany gave two presentations (GRSP-62-35 and GRSP-62-36) to introduce a proposal of amendment (GRSP-62-12) to the UN Regulation aimed at removing the static tests and improving the dynamic test on seat anchorages. Referring also to the video presentations Nos. 1 and 2, he provided evidence that seat anchorages tested statically do not reach the same level of safety as that tested dynamically and, therefore, they cannot be considered as equivalent. GRSP agreed to resume discussion on this subject at its May 2018 session and requested the secretariat to distribute GRSP-62-12 with an official symbol.
