59. The expert from OICA recalled that the purpose of ECE/TRANS/WP.29/GRSG/2018/23 was to correct the scope of the UN Regulation. The expert from the Russian Federation proposed further editorial corrections and amendments (ECE/TRANS/WP.29/GRSG/2019/18) which allow contracting parties to apply the relevant requirements to assess compliance of Accident Emergency Call Devices (AECD) designed for installation on vehicles of categories other than M1 and N1. The expert from the Russian Federation introduced ECE/TRANS/WP.29/GRSG/2019/23 extending the scope of application for AECD, if fitted to other categories than M1 and N1.

60. GRSG welcomed GRSG-117-47 prepared by the expert of the Russian Federation providing a consolidated text of the regulation including the necessary corrections and proposed amendments.

62. GRSG adopted ECE/TRANS/WP.29/GRSG/2019/18 and requested the secretariat to submit it together with the rectified wording of subsection 26.7.2.3. (see para. 61 above) to WP.29 and AC.1 as draft supplement 01 to UN Regulation No. 144 for consideration at their March 2020 sessions.
