The expert from Japan, ambassador of IWVTA, explained that the amendments to General Guidelines for Transitional Provision clarifies that the contracting parties may and shall continue to grant type approvals to the previous series, and that this amendment had been adopted as Revision 3 at the 2021 March session of WP.29. He added that a second item discussed in IWG was regarding the proposal for the 04 series of amendments to UN Regulation No. 0, amending annex 4. He clarified that the proposed amendment to annex 4 (listing the UN Regulations that apply to UN Regulation No. 0), added UN Regulation No. 154 (WLTP) and new UN Regulations Nos. 161, 162 and 163, and reflected a new series amendments to existing UN Regulations (i.e.: UN Regulation No. 95). He reported that the amendment had been adopted at the November 2021 session of WP.29 (ECE/TRANS/WP.29/2021/84). Moreover, he reported that at the last IWVTA IWG meeting, held in November 2021, it was noted that the 04 series lacked transitional provisions and for this reason a supplement incorporating them would be proposed at the March 2022 session of WP.29. He announced that a proposal for the 05 series of amendments to UN Regulation No. 0, updating annex 4 was underway, and it was expected that an informal document would be submitted to the June 2022 session of WP.29. Finally, he informed GRSP that IWG was studying improvement measures to promote IWVTA approval, for example, discussing a process to better inform of the actual minimum requirements applicable in the various Contracting Parties for possible inclusion in document ECE/TRANS/WP.29/343 on the status of the 1958 Agreement and its UN Regulations.

The expert from Finland, on behalf of the IWG on Database for Exchange of Approval documentation (DETA) introduced the proposal for extension of DETA to improve the use of the Unique Identifier (UI) for UN Regulations (GRSP-70-04). He also added that the UI would be available at the end of next year due to software adaptation. GRSP for the time being noted that the use of UI could not be applied to UN Regulations Nos. 22, 44 and 129. He clarified that for these UN Regulations enforcement authority needed type approval data at hand to comply with enforcement controls.
