8. The expert of IWG SLR presented draft amendments to UN Regulations Nos. 148, 149 and 150 that introduce summary documents to be placed in the electronic Database for the Exchange of Type Approval documentation (DETA) to support the use of the Unique Identifier (UI) (ECE/TRANS/WP.29/GRE/2022/10, ECE/TRANS/WP.29/GRE/2022/11 and ECE/TRANS/WP.29/GRE/2022/12). GRE pointed out that a template summary document should be developed by IWG DETA and endorsed by WP.29. Awaiting WP.29 and/or IWG DETA guidance on the matter, GRE decided to continue consideration at the next session.

9. GRE noted that the use of UI for a particular UN Regulation should only be possible when the following two conditions are met:

• the corresponding summary document has been defined in the Regulation; and
• DETA is providing access to the Summary Document.

10. To stress these requirements, the expert from EC proposed an amendment (GRE-87-24-Rev.1). GRE adopted the proposal and requested the secretariat to submit it for consideration and vote at the March 2023 sessions of WP.29 and AC.1 as a draft Supplement to the 00 and 01 series of amendments to UN Regulations Nos. 148, 149 and 150.

11. In the context of possible replacement of traditional approval markings by UI, the expert from CITA presented a proposal with the aim to ensure the availability of sufficient information on the device for periodic and roadside inspections (ECE/TRANS/WP.29/GRE/2022/13 and GRE-87-07). GRE agreed to revert to this proposal at the next session.
