33. The expert from Germany presented ECE/TRANS/WP.29/GRSG/2015/17 and GRSG-108-48 introducing into UN Regulation No. 58 more stringent requirements for rear underrun protection devices. The expert from IRU informed GRSG about the road transport sector’s point of view (GRSG-108-07) concerning the strengthening of the requirements for rear underrun protection devices, and proposed an amendment to the new paragraph 16.7. The expert from CLCCR raised a number of concerns (GRSG-108-13) and proposed some amendments to the proposed text. The expert from OICA introduced GRSG-108-27 and GRSG-108-28 clarifying the transitional provisions and the text of the new technical requirements proposed by Germany. GRSG noted the concerns raised by the expert from India on the basis of GRSG-108-40.

34. Following the discussion, GRSG adopted ECE/TRANS/WP.29/GRSG/2015/17, amended as reproduced in GRSG-108-48-Rev.2. The secretariat was requested to submit the adopted proposal to WP.29 and AC.1 for consideration at their November 2015 sessions, as draft 03 series of amendments to UN Regulation No. 58.

20. Recalling the discussion on GRSG-106-32 during the previous session of GRSG, the expert from Germany introduced GRSG-107-30 superseding ECE/TRANS/WP.29/GRSG/2014/18 and proposing more stringent requirements for rear underrun protection devices. The expert from OICA preferred to exclude vehicles of category N2 from the proposal, due to their limited presence in the current traffic fleet. The expert from CLCCR suggested splitting vehicle category N2 and addressing only those having design similarity with N3. The expert from Japan required more time to assess the impact of the proposal including the splitting of vehicle category N2. Following the discussion, the expert from Germany introduced a revised proposal (GRSG-107-39). GRSG agreed to resume discussion at its May 2015 session, taking into account the study reservation of some experts.

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 secretariat was requested to keep GRSG-106-32 on the agenda.
