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.

GRPE
Air-conditioning system was prioritized © because there is no corresponding UN Regulation for air-conditioning system. However, consideration of air-conditioning system is in progress in GRPE from two different aspects, i.e., (i) reducing CO2 emissions and improving overall efficiency, and (ii) test methods to measure leakages of fluorinated greenhouse gases from certain air conditioning systems (EC Regulation 706/2007 and EC Directive 2006/40).

GRB
The responsible organizations to review the UN Regulations for GRB are as follows;
-R28 “Audible warning” prioritized (a): CLEPA
-R51 “Permissible sound level” prioritized (b): OICA
(OICA will perform preliminary review by the next GRB session.)
-R117 “Tire rolling noise/RR” prioritized (a): ETRTO

GRRF
-R13H prioritized (b); OICA will take the role to split R13H into three pieces. i.e., “Braking”, “ESC” and “BA”.
-R79 Steering effort” was prioritized (a) if “LKAS” is not be part of R79.
-ETRTO agreed to sponsor the work of “Tire installation” prioritized (b). OICA committed to provide support to ETRTO in this exercise, as this will be a vehicle regulation. The new Regulations will be formulated based on the EU Directive on tire installation.
-R89 “Speed limiters” was prioritized ©.
-R55 “Coupling” was prioritized © because the equipment rate of coupling is as low as 10%.
-It is expected that four documents on “Braking”, “ESC”, “BA” and “Tire installation” will be provided by OICA hopefully before this summer.

GRSG
-Some Contracting Parties at GRSG questioned the opportunity of adding national requirements into UN regulations for the sake of introduction into IWVTA.
-Japan responded that even if the national requirements are proposed to be added into UN Regulations, they will probably not be approved by the respective GRs without legitimate justification.

GRSP
R25 “Head Restraint System”, R94 “Frontal Impact” and “FCV” were prioritized as (b). These activities are in progress by respective Informal Groups.

GRE
