40. The expert from the Russian Federation, chairing the IWG on AECS, presented an updated proposal of draft UN Regulation on AECS (ECE/TRANS/WP.29/GRSG/2017/12). As Secretary of the IWG on AECS, the expert from OICA introduced GRSG-112-15 proposing some further editorial corrections to ECE/TRANS/WP.29/GRSG/2017/12. The expert from the Russian Federation introduced GRSG-112-27 clarifying mainly the scope and definitions of the draft UN Regulation. She informed GRSG that from, a technical point of view, the corridor of sled pulse (60g) specified in ECE/TRANS/WP.29/GRSG/2017/12 was severe enough, but taking into account the importance and urgency for the adoption of the new UN Regulation by all Contracting Parties, the Russian Federation would support the more stringent corridor (65g) in line with the EU legislation. The expert from OICA reiterated a concern about the economic burden for technical services and laboratories offering the more stringent tests due to the considerable costs of test equipment performing such acceleration/declaration of 65g.

41. Following a detailed consideration of ECE/TRANS/WP.29/GRSG/2017/12, GRSG adopted the new UN Regulation on AECS as reproduced in GRSG-112-42, subject to a final review at its October 2017 session of the official translations into the French and Russian languages. The GRSG Chair thanked again for the excellent work done by the IWG and for the acceptance by the Russian Federation to support the final proposal. The secretariat was requested to submit the adopted proposal to WP.29 and AC.1 as new draft UN Regulation on AECS for consideration at their November 2017 sessions, subject to a final review at the forthcoming GRSG session.
