CLCCR recommendation to establish an expert group to further consider the German proposal to raise rear underrun protection device (RUPD) requirements. CLCCR raises concerns over the cost-benefit and in particular, over the relative effectiveness of higher requirements across the range of vehicle categories that would be affected.

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.

Proposal to clarify and refine the draft amendments proposed in document GRSG/2015/17 “Proposal for the 03 series of amendments to UN Regulation No. 58”.
