Status

Formal GR review

Subject

UN R150 Retro-reflective Devices (RRD)

Impact

01 series of amendments | Supplement 3

Meeting(s)

GRE | Session 94 | 27-30 Apr

Agenda item 7. (c) UN Regulation No. 150

Proposal to amend UN R150-01 addressing three main issues. First, since the GRE-adopted proposal to delete the unique identifier (GRE-92-18) was not part of the March 2026 WP.29 submission, the regulation text requires amendment in the interim, though this may become unnecessary if merged with GRE-92-18. Second, the approval marking approach is aligned with UN R148 by including one example in the body text and referencing other arrangements in Annex 10, allowing deletion of the Table 1 reference and redundant ratio explanations from Figure A10-I. Third, the outdated requirement for function symbols to be placed diametrically opposite the approval number - inherited from UN R3 and R7 but already removed in UN R148 - is deleted from Annex 10, along with a clarifying amendment to the note below Figure A10-I to prevent inconsistent interpretations among technical services. Further details can be found in informal document GRE-94-11.

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).

31. The expert from GTB proposed aligning the marking location requirements with those of UN Regulation No. 148 (ECE/TRANS/WP.29/GRE/2026/14 as amended by GRE-94-11).

32. The expert of IWG SLR proposed correcting errors and omissions in UN Regulation No. 150 (ECE/TRANS/WP.29/GRE/2026/3 as amended by GRE-94-02-Rev.1). Some experts raised questions on how type approval authorities could verify compliance with the provisions of a new Part 7 of Annex 6 on colour fastness. The expert from the Republic of Korea introduced further corrections (GRE-94-24).

33. GRE agreed that all draft amendments in paras. 31 and 32 above, as well as the pending ones in GRE-92-18 on UI, should be consolidated in a single formal document as draft Supplement 3 to the 01 series of amendments to UN Regulation No. 150, for revisiting at the October 2026 session of GRE and subsequent submitting to the March 2027 sessions of WP.29 and AC.1. GTB volunteered to prepare a consolidated document.
