At the 74th GRRF session, CLCCR presented document GRRF-74-37 which noted that a design restriction in UN R79 prevents trailers from using energy from a towing vehicle. Following discussion, a number of delegates indicated their support for an amendment to remove this restriction and enable the use of new technologies.
48. The expert from CLEPA recalled, on behalf of CLCCR, the proposal ECE/TRANS/WP.29/GRRF/2016/20 previously adopted by GRRF with a scrutiny reservation. CLCCR reviewed the text in square brackets and proposed to delete it as proposed in GRRF-81-13. GRRF adopted the proposal as amended by Annex V to the report and requested the secretariat to submit it together with ECE/TRANS/WP.29/GRRF/2013/13 to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 5 to the 01 series of amendments to Regulation No. 79.
54. The expert from CLEPA introduced on behalf of CLCCR the proposal ECE/TRANS/WP.29/GRRF/2015/43 superseding ECE/TRANS/WP.29/GRRF/2015/8. The proposal received some comments and was amended during the session as reproduced in GRRF-80-40. GRRF agreed with the proposal but preferred to review it again in February 2016 in view of a possible adoption in June 2016 by WP.29 and AC.1.54
40. The expert from CLEPA, on behalf of CLCCR, introduced ECE/TRANS/WP.29/GRRF/2014/8 as amended by GRRF-79-02 and GRRF-79-21, aimed at removing a design restriction from Regulation No. 79 that prevents the approval of new technologies. The proposal received some comments. GRRF agreed to resume consideration on this item at its September 2015 session based on a revised proposal that the author volunteered to prepare. The secretariat agreed to consult the Working Party on Lighting and Light-Signalling on the issue of trailer mounted warning light.
31. At the request of the author of ECE/TRANS/WP.29/GRRF/2014/8, GRRF agreed to defer this agenda item to its next session.
37. On behalf of CLCCR, the expert from CLEPA proposed amendments to UN Regulation No. 79 (ECE/TRANS/WP.29/GRRF/2013/25) inserting new requirements for trailers with a steering control system utilising electrical energy from the towing vehicle. The proposal received some comments (GRRF-75-11). The expert from Japan noted the absence of a definition for “IP54”. GRRF agreed to resume consideration of this subject at its next session on the basis of a revised proposal.
