43. The secretariat reported on the activities of the IWG on IWVTA and its subgroups. The expert from Japan, GRSP ambassador to IWVTA introduced WP.29-164-22-Rev.1, providing an outline of the latest update of draft UN Regulation No. 0 that would be annexed to the Revision 3 of the 1958 Agreement. The expert from Australia informed GRSP about the difficulties to transpose UN Regulation No. 14 into the national legislation of his country, due to the conflict of its upper tether provisions with those of the corresponding Australian Design Rule (ADR). The expert from Germany recognized the relevance of UN Regulation No. 14 for the IWVTA and encouraged to find a solution on this issue by the May 2015 session of GRSP.

49. The representative of Japan, Vice-Chair of the IWG on IWVTA, reported on the work progress made during the meetings held in Paris on the development of draft UN Regulation No. 0 (WP.29-164-21), explaining that the IWG had agreed to submit a second draft to WP.29 for consideration. He gave a presentation on the remaining issues (WP.29-164-22) and sought the advice of WP.29 on: (i) a definition of vehicle type, (ii) the establishment of a Declaration of Conformance (DoC) and (iii) a common procedure for replacement spare parts to be fitted on vehicles covered by an IWVTA.

50. The World Forum underlined the crucial need to develop a harmonized definition for a type of vehicle. WP.29 agreed to re-activate the informal group on the electronic Database for the Exchange of Type Approval documentation (DETA) to develop a harmonized DoC process. WP.29 also agreed to defer to its next session, the decision on how to handle the procedure for replacement spare parts intended to be fitted on vehicles covered by an IWVTA. In this respect, delegates were invited to present their preference on the two options listed in item 5-2 of WP.29-164-22. WP.29 noted the GRE was considering the best possible solution for IWVTA to solve the problem with the installation of DRL (see para. 42 above).
