66. The expert from the Russian Federation introduced ECE/TRANS/WP.29/GRVA/2019/25, proposing amendments to UN Regulation No. 90 on provisions on the approval making and the approval number. The expert from CLEPA thanked the expert from the Russian Federation for having developed an elegant and creative solution to the marking requirement. GRVA supported the proposal. GRVA also agreed to identify the provisions for Category L6 and L7 vehicles as being identical to the M1 and N1 provisions (as noted in GRVA-04-54). GRVA agreed that the Unique Identifier should not be used as an alternative to the marking provisions in the Regulation. GRVA asked the secretariat to add provisions on the marking size for small parts that could not accommodate the size provision in the Regulation. GRVA requested the secretariat to provide a consolidated text to WP.29 and AC.1 for review and vote at their March 2020 sessions.

82. The representative of Germany, on behalf of the IWG on DETA presented the status report (WP.29-178-22) of the activities of the group, and the report of the last session (WP.29-178-23). He informed WP.29 that DETA was operational for the exchange of type approval documentation and that 16 contracting parties already had notified [Germany of] their DETA focal point. He explained that DETA was still being developed to include the Unique Identifier (UI) and the Declaration of Conformance (DoC) functionalities. He presented the expected timeline for their implementation. He invited WP.29 to consider for endorsement the specifications of UI (WP.29-178-26/Rev.1) and DoC (WP.29-178-25). He recommended that WP.29 invite GRs, in the context of UI, to consider whether current additional marking provisions were still to be considered part of the approval marking and could be replaced by the UI marking, or these additional markings have an information character and could be provided by alternative means (e.g. insertion in the Communication Form). WP.29 agreed with this suggestion. This was necessary as the current version of the software was not able to render all marking variations

83. The secretariat insisted on the need to review the specifications of the DETA software extensions (delivering UI and DoC) as these would be the basis for developing these functions and as future amendments to them could have financial implications. He added that IWG was informed of difficulties for the involved parties, software house and sponsors, to establish contracts because contractual clauses would involve parties not being signatories of the contact (e.g. the DETA host).
