39. The IWVTA Ambassador reported on the progress made by the IWG on IWVTA and the availability of the draft UN Regulation No. 0 (WP.29-162-04). He highlighted the ongoing discussion on the relevant content of lists A and B for UN Regulation No. 0, noting that UN Regulation No. 85 was in list A and that both UN Regulation No. 101 and WLTP were listed in List B. He echoed the comments made by the Chair on WLTP (see para. 10 above).
40. The secretariat also reported on the progress made on draft Revision 3 of the 1958 Agreement (ECE/TRANS/WP.29/2014/53) and referred to WP.29-162-12-Rev.1 as well as WP.29-162-18. He added that the draft Revision 3 of the Agreement included some new elements:
(a) Allowing Contracting Parties to grant type approvals according to former versions of UN Regulations;
(b) Triggering the mandatory application by Contracting Parties of new series of amendments to UN Regulations on a common commencement date (e.g. 1 September each year). These elements would permit to yearly collect into a single amendment to UN Regulation No. 0 all newly adopted amendments to existing UN Regulations and new UN Regulations;
41. The secretariat added that the Group was proposing to better follow the definitions of Supplements and series of amendments to ease the IWVTA process and that a set of amendments to a UN Regulation would only be permitted once a year. He concluded that guidelines for transitional provisions (ECE/TRANS/WP.29/1044/Rev.1) would be amended accordingly.
42. The GRPE Chair clarified that no further action was needed from GRPE at the moment.
