67. The representative of Japan, Chair of the IWG on IWVTA, reported on the progress made by the group at the twenty-seventh meeting of the IWG on IWVTA held in June 2018 in The Hague, Netherlands (informal document WP.29-175-13). He informed WP.29 about the proposed amendments to Schedule 4 on the numbering of UN type approvals allowing the use of a four- to six-digit sequential number. He also reported on the proposed procedure to fill-in the extension number in existing and new communication forms. He also highlighted the potential to amend the approval numbering in UN Regulations Nos. 37, 90, 99, 108, 109, 117 and 128 for alignment with Schedule 4. WP.29 endorsed the proposals and requested GRB, GRE and GRRF to review, in this respect, the provisions of the UN Regulations concerned.

68. WP.29 invited the secretariat to prepare an official document with the proposed amendments to Schedule 4 for consideration at its November 2018 session. WP.29 noted that this proposal would result in a first amendment to the Schedules of the 1958 Agreement and that its adoption according to the new provisions of article 13.bis of revision 3 would require some additional time for clearance in some of the CPs.

69. The Chair of GRRF expressed his concern that this amendment would not necessarily solve the problems which occurred under UN Regulation No. 90 on replacement braking parts as these parts were approved as groups with a single approval number. WP.29 noted the concern raised by GRRF about revision 3 to the 1958 agreement and its possible impact of the issuing of approvals to UN Regulation No. 90, using the test group approach (and extensions to approvals issued in this way). WP.29 agreed that the test group practices which were valid under revision 2 of the 1958 agreement should remain available for use under revision 3. Thus, WP.29 requested the IWG on IWVTA to consider any amendments to the agreement, or to Schedule 4, that may be required to improve transparency on this point.

70. WP.29 noted the informal document WP.29-175-14 that proposes to amend annex 4 to UN Regulation No. 0 with the updated list of UN Regulations. The World Forum welcomed the proposal and agreed to resume consideration and possible vote in AC.1 at its next session in November 2018. Thus, the secretariat was requested to circulate the informal document WP.29-175-14 with an official symbol.
