13. | UN Regulation No. 80 (Strength of seats and their anchorages (buses))

22. The expert from Germany introduced GRSP-64-22 and
GRSP-64-23 superseding ECE/TRANS/WP.29/GRSP/2018/10, aimed at removing Appendix 5 (static test requirements and procedure) from UN Regulation No. 80 (GRSP-64-22) and at improving the dynamic test (GRSP-64-23) in two different series of amendments. The expert from OICA suggested that both tests be maintained as alternatives and that the static test be improved as a first step. The expert from Italy supported the approach of the expert from OICA. The expert from the Russian Federation introduced GRSP-64-19 and Add.1, proposing to include the assessment of the dummy neck injury criteria into the dynamic test of the UN Regulation. The Chair of GRSP suggested creating a task force of concerned parties led by Germany to provide a revised official document that would incorporate GRSP-64-19 and other comments submitted to the secretariat by 15 February 2019. The expert from Germany agreed with the Chair’s proposal and the expert from OICA offered his contribution in drafting the revised document.

26. (g) | UN Regulation No. 80 (Seat Strength of Coaches and Buses)

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.
