Task force GTR 15-Phase 1b consolidated amendments based upon document GRPE-72-10/Rev.2.

Draft text for Annex 8: Pure electric, hybrid electric and compressed hydrogen fuel cell hybrid vehicles.

1) Bag measurements vs continuous diluted sampling and 2) Calibration gases and mixtures

Starting note for correction factors for the dynamometer roller radius, additional cooling fan, and alternative road load determination process.

Proposal to clarify procedures (calculation of dynamometer setting coefficient) and number of coast-down runs required.

Draft proposal for consideration of testing where the test track is too short to coast down from ~145 km/h to ~15 km/h within a single straight track, thus necessitating split runs.

Proposal for a mandate to develop provisions under GTR No. 15 to check the level of specific pollutant emissions of vehicles corresponding to conditions encountered during the winter season.

Draft proposal for a mandate to develop two different types of tests:

a) In-service-conformity (ISC) testing to be done by the manufacturer and the authority responsible for issuing the emission type approval and intended to assess the durability of emission control systems over a certain period of use.

b) Verification testing typically to be done by an independent third party, i.e. an authority not involved in the initial type approval process, NGOs or the manufacturers’ peers, in order to check the integrity of the initial approval test itself and to ensure that the use of (partially inevitable) test flexibilities by the manufacturer is limited.

Goals and objectives for the task force established to draft provisions for GTR No. 15 to ensure that pollutant emissions do not exceed emission limits throughout the lifetime of the vehicle.

Presentation on post-processing procedures for OVC-HEV and PEV (Shortened Test Procedure).

Starting note for the OBD Task Force established for the development of OBD requirement compatible with the WLTP test cycles (and potentially as a separate GTR from GTR No. 15) during the Phase 2 work on GTR No. 15.

Clarification of n/v ratios (engine rotational speed divided by vehicle speed) and vehicle mass definitions.

Table based upon document GRPE-72-10/Rev.2 reviewing errors and inconsistencies remaining in the GTR text.

Presentation of Japanese research into a normalization method to compensate for tolerances allowed under the proposed hybrid electric vehicle emissions and energy consumption test procedures.

Update on EU experiences with the initial GTR No. 15 test procedures.

Report on the efforts to resolve outstanding issues concerning the gearshifting requirements under the WLTP test cycle, including items raised during validation phases of the initial GTR procedures.

Report of the task for established to resolve issues regarding the testing of 2WD and 4WD vehicles on single and dual axis dynamometers (in support of EU plans for new regulatory requirements in 2016) following its first session.
