14. The expert from ISO reported on technical measurement development for standard ISO 16254 (GRBP-75-03). He also presented an updated standard ISO 10844:2021 (GRBP-75-02-Rev.1/Add.1) and proposed to include it into UN Regulations Nos. 51, 117 and 138 (GRBP-75-02-Rev.1). GRBP invited the expert from ISO to submit an official document to the next session.

15. GRBP recalled several proposals that had been briefly considered at the previous session (ECE/TRANS/WP.29/GRBP/72, para. 12). In view of a range of draft amendments to UN Regulation No. 138, GRBP agreed to start this work within a dedicated task force on quiet road transport vehicles (TF QRTV) which could later be transformed into an informal working group. The expert from OICA prepared draft Terms of Reference (GRBP-75-42) which received comments from the expert of China (GRBP-75-44). GRBP sought a Contracting Party who could take the lead of the task force, thanked OICA for having agreed to act as secretary and requested that the first meeting of the task force be convened in the coming months.
