Proposal to introduce a tolerance for the position of the loading device during the test. The loading device is required to be parallel to the x-y plane of the chassis. This proposal would add a z dimension to the x-y plane and set a tolerance such that the loading device may not deviate by more than 5° along the z-axis.

Discussion(s):
Working Party on Passive Safety | Session 62 | 12-15 Dec 2017

19. GRSP resumed discussion of GRSP-62-11 on proposed tolerances for the position of the loading device during the test. GRSP noted that the proposal had already been agreed in principle during the sixty-second GRSP session (ECE/TRANS/WP.29/GRSP/62, para. 20). The expert from OICA requested further consultation on the proposal and GRSP requested the secretariat to distribute GRSP-62-11 with an official symbol at its May 2019 session.

20. GRSP agreed (ECE/TRANS/WP.29/GRSP/2017/26) on how to secure a cab mounted on a vehicle on the test rig allowing the use of rigid composite blocks and/or metal brackets instead of the wooden blocks (Annex 3, Appendix 1, para. 1), and on the necessity to secure the vehicle with ropes or chains for test C. The expert from Germany introduced GRSP-62-11 on tolerance for the position of the loading device during the test. GRSP agreed in principle with GRSP-62-11, to combine both documents and to resume discussion at the May 2018 session of GRSP to allow for any further provisions. The secretariat was requested to distribute GRSP-62-11 with an official symbol at the next session of GRSP.
