The expert from France presented ECE/TRANS/WP.29/GRRF/2018/9, aimed at harmonizing the definitions and provisions in Regulation No. 109 with those introduced in UN Regulations Nos. 30, 54 and 117. The expert from ETRTO introduced GRRF-86-24, proposing amendment to this proposal. GRRF adopted the proposal as amended by Annex VI (of the session report) and requested the secretariat to submit it as draft supplement 9 (note: corrected by GAR from Supplement 4 in the published report.) to UN Regulation No. 109. GRRF requested the secretariat to address corrections to the French version of the document suggested by the expert from France.
