Proposal for amendments to UN Regulation No. 58
Download in .pdf format

Proposal to clarify restrictions on the application of an RUPS according to specific vehicle chassis characteristics (e.g., stiffness, profile dimensions) under Annex 1 (item 9) the test set-up Annex 1 item 9 and to adapt the test procedure of Annex 5 (paragraph 1.1.3.) accordingly by the use of representative side rails. The proposal would also specify that the device used to distribute the test force over the stated flat surface be connected to the force actuator through a swivel joint since a wholly rigid set up can result in very different and unintended outcomes.

Recalling the purpose of ECE/TRANS/WP.29/GRSG/2013/27, the expert from Germany presented ECE/TRANS/WP.29/GRSG/2014/18 and GRSG-106-26 introducing into UN Regulation No. 58 more stringent requirements for rear underrun protection devices. The expert from OICA proposed ECE/TRANS/WP.29/GRSG/2014/11 on alternative provisions. The expert from Germany presented GRSG-106-32 with a comparison of the proposed requirements listed in the documents. The expert from CLCCR presented some observations and recommendations of his organization (GRSG-106-11). The expert from Sweden raised concerns related to the test conditions for type-approval of rear underrun protection devices (GRSG-106-40). GRSG noted a number of comments.

29. Following the discussion, GRSG agreed to resume consideration at its next session in October 2014, on the basis of a revised official document to be prepared by the experts from Germany jointly with the experts from Sweden, CLCCR and OICA. The secretariat was requested to keep GRSG-106-32 on the agenda.
