58. The GRPE Ambassador to IWG on International Whole Vehicle Type Approval (IWVTA) introduced GRPE-78-05-Rev.1 which lists the GRPE-related UN Regulations and their status for a potential inclusion in UN Regulation No. 0. The secretariat informed GRPE that GRPE, as a formal body under WP.29, can decide on which UN Regulations to include, taking the opinion of IWG on IWVTA into account.
59. The representatives from Switzerland, UK and EC supported the inclusion of UN Regulation No. 133 into UN Regulation No. 0. The Chair also indicated that UN Regulation is part of the European Union Whole Vehicle Type Approval (EUWVTA), and therefore there should not weaken national legislations because of IWVTA.
60. The representative from Japan did not support the introduction of UN Regulations Nos. 24, 49 and 133 into UN Regulation No. 0.
61. The secretariat and Chair informed GRPE that candidate UN Regulations to UN Regulation No. 0 are reviewed annually and that the possibility of Limited IWVTA (L-IWVTA) existed for Contracting Parties not willing to accept Uniform IWVTA (U-IWVTA).
62. GRPE requested Contracting Parties to raise their interest at the next IWVTA meeting in March 2019 to work on UN Regulations, such as UN Regulations Nos. 24 and 49 that need to be split to be included into UN Regulation No. 0.
63. The GRPE Ambassador to IWG on IWVTA introduced GRPE-78-06 which reviews the provisions about approval numbering in UN Regulations developed and maintained by GRPE. He highlighted, for example, the impossibility for certain characters to be used in approval numbering such as “*” that were used in UN Regulations Nos. 115 and 143 to specify fuel type.
64. The Chair asked each Contracting Party to request their Type Approval Authorities if the approval numbering was in compliance with Schedule 4 of the 58 Agreement.
65. The representatives from France, the Netherlands and UK committed themselves to internally verify this compliance.
