29. The expert from CLEPA presented GRRF-74-37, on behalf of CLCCR, proposing to introduce into Regulation No. 79 provisions permitting the type approval of positive steering of trailers using energy supply and electrical control from the towing vehicle. His proposal focused on the energy supply connectors and the transmission of steering control data (digital information interchange). The expert from the Netherlands proposed extending the work to the power supply provisions necessary to guarantee a good functionality as well as a sufficient level of safety. GRRF agreed to add this as a new item on the agenda of the next session.

30. The expert from CLEPA introduced ECE/TRANS/WP.29/GRRF/2013/5 proposing to align the test speed and braking performance requirements for vehicles of the category M1 and N1 in the event of energy source failure with those in Regulations Nos. 13 and 13-H. GRRF adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2013 sessions as draft Supplement 4 to the 01 series of amendments to Regulation No. 79.

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.

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.

41. The expert from CLEPA, on behalf of CLCCR, introduced ECE/TRANS/WP.29/GRRF/2014/8 aimed at removing a design restriction from UN Regulation No. 79 that prevents the approval of new technologies. He explained that the proposal was not intended for immediate adoption and he invited all interested experts to send him their comments (colin.ross@meritor.com). GRRF agreed to resume consideration of this matter on the basis of a revised proposal by CLEPA.

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.

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

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.
