45. The expert from OICA introduced GRRF-79-05, GRRF-79-06 and GRRF 79 07 superseding official proposals for separate Regulations on Brake Assist Systems (BAS) (ECE/TRANS/WP.29/GRRF/2014/11) and on Electronic Stability Control (ESC) (ECE/TRANS/WP.29/GRRF/2014/12) extracted from Regulation No. 13 H (ECE/TRANS/WP.29/GRRF/2014/10). GRRF agreed that further work e.g. on the transitional provisions, was necessary to make sure that Countries mandating the fitment of ESC or BAS on the basis of the existing text of Regulation No. 13-H would be able to continue to mandate this fitment, unaffected by this extraction. The expert from UK agreed to lead an ad-hoc group of interested members on addressing the transitional provisions, to establish a methodology for all of the regulations that would need to be separated for IWVTA. GRRF agreed to reconsider this proposal at its September 2015 session.
