Under the International Whole Vehicle Type Approval (IWVTA) program, brake assist systems (BAS) and electronic stability controls (ESC) would be separated from UN R 13-H into new stand-alone regulations.

The expert from the UK recalled, on behalf of the group of interested experts dealing with this matter, the purpose of 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). She then introduced ECE/TRANS/WP.29/ GRRF/2015/33 as amended by GRRF-80-32 proposing transitional provisions 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. GRRF agreed to reconsider this proposal at its February 2016 session.
