62. The IWVTA ambassador reported on the priority of discussion on technical requirements for the IWVTA that concerns UN Regulations under GRPE. He explained that, following the decision of WP.29, the UN Regulations expected to require only minor amendments should be considered in a first review step, while the UN Regulations expected to require major amendments should be reviewed in a second step. He illustrated the time schedule outlined for the review process, inviting Contracting Parties to submit to him, by April 2013, eventual changes to the expected amendments of UN Regulations (as foreseen in GRPE-65-19). He explained that the presentation of all the resulting changes to GRPE from the ambassador is scheduled for May 2013, while the agreement by GRPE on the priorities, as well as the appointment of the sponsors for the first review step, are scheduled for June 2013. He stated that a progress report for WP.29 is also expected for June 2013. Sponsors for the second review step shall be appointed in January 2014.

63. Considering the GRPE-related aspects in greater detail, he mentioned that the review of UN Regulation No. 85 (measurement of the net power and the 30 min. power) needs minor changes and it is therefore expected for the June 2013 session of GRPE. UN Regulation No. 101 (CO2 emissions/fuel consumption) and the UN GTR resulting from the WLTP activity, requiring the sponsors appointed in June 2013, should also be considered in a first review step. The review of UN Regulations Nos. 24 (visible pollutants, measurement of power of compression ignition engines/diesel smoke), 49 (emissions of compression ignition and positive ignition (LPG and CNG) engines), 83 (emissions of M1 and N1 vehicles) and the UN Regulation resulting from the MACTP activity (air-conditioning system) shall take place in the second step.

64. Having highlighted the difficulties faced on bringing the integration of European whole vehicle type approval under the ECE structure, the expert from OICA warned GRPE about the need to coordinate on the matrix document – necessary for the whole vehicle type approval – and asked whether Working Parties are supposed to play a pro-active role in this context. The IWVTA ambassador clarified that this is likely to be one of the issues addressed by the IWVTA group working on UN Regulation No. 0. The Chair of GRPE expressed his intention to further investigate this issue, so that it can be fully clarified in the next GRPE session.
