10. The expert from Germany introduced GRRF-76-24 based on ECE/TRANS/WP.29/GRRF/2013/29 and proposing amendments to Regulation No. 13 introducing provisions for electro-mechanical braking systems. GRRF acknowledged the status report and expected a revised proposal at its September 2014 session, addressing the remaining open issues, which the experts from Germany and the Netherlands volunteered to prepare.

13. The expert from Germany questioned the decision of GRRF taken in 2004 to exclude the use of the overrun brake for a full trailer (TRANS/WP.29/GRRF/2004/11) and not extended to electrical brakes according to Annex 14. The expert from the Netherlands noted that the conscious decision in 2004 to exclude overrun brakes for full trailers was design restrictive. He suggested that the corresponding provisions should be replaced by performance requirements.
