Proposal for amendments to Regulation No. 29
Document GRSP-61-20
5 May 2017

Proposal to introduce installation specifications for securing a cab mounted on a vehicle to the test rig for tests B and C, as is currently provided for test A, under UN R29. This proposal aims to improve repeatability and reproducibility while allowing more flexibility in permitting the use of rigid composite blocks and/or (adjustable) metal brackets in securing the vehicle in the place of the wooden block presently prescribed in Figure 1.

11. | Regulation No. 29 (Cab strength)

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.
