GRE | Session 93 | 21-23 Oct 2025

9. GRE recalled the package of amendment proposals to UN Regulations Nos. 148, 149 and 150 that had been submitted by the expert from Netherlands (Kingdom of the) with the aim to take onboard the recent amendments to Schedule 5 of the 1958 Agreement on the Unique Identifier (UI) (GRE-92-13, GRE-92-14, GRE-92-15, GRE-92-16, GRE-92-17, GRE-92-18). GRE adopted these proposals and decided to merge them with other possible amendment proposals to the same series of amendments before submitting to WP.29.

22. The experts from GTB proposed to correct an editorial error in the markings for light source control gear and to provide clarification in case the tolerance limits are calculated (ECE/TRANS/WP.29/GRE/2025/11, ECE/TRANS/WP.29/GRE/2025/12). GRE adopted the proposals and requested the secretariat to submit them for consideration and adoption to the March 2026 sessions of WP.29 and AC.1 as draft Supplement 6 to the 01 series of amendments to UN Regulation No. 148. GRE also mandated the secretariat to merge these proposals with the ones in GRE-92-14 (see para. 9 above).

GRE | Session 92 | 22-25 Apr 2025

11. The expert from the Netherlands (Kingdom of) recalled the recent amendments to Schedule 5 of the 1958 Agreement on the Unique Identifier (UI) and presented a package of amendment proposals to UN Regulations Nos. 148, 149 and 150 (GRE-92-13, GRE-92-14, GRE-92-15, GRE-92-16, GRE-92-17, GRE-92-18). Some experts requested more time to study these proposals. GRE noted that the proposals were not urgent and could be combined with other amendments to the same UN Regulations in the future. Finally, GRE decided to revert to these proposals at the next session. In the interim, GRE invited experts to send their comments to the expert from the Netherlands (Kingdom of).
