59. The Chair of the IWG presented ECE/TRANS/WP.29/GRPE/2016/2 on a new GTR on evaporative and crankcase emissions for two- or three-wheeled motor vehicles equipped with a combustion engine as well as the modifications to the proposal introduced by GRPE-72-13. He introduced the technical report on the development of the new GTR (GRPE-72-06).

60. GRPE adopted ECE/TRANS/WP.29/GRPE/2016/2 as amended by Annex VI of the session report and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2016 sessions as a draft GTR on the measurement procedure for two- or three-wheeled motor vehicles equipped with a combustion engine with regard to the crankcase and evaporative emissions. GRPE also adopted the technical report (GRPE-72-06) as reproduced in Addendum 3 to this report and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2016 sessions.

44. The Chair of the IWG on EPPR presented a status report (GRPE-71-22) on the activities of the group and, in particular, on the work progress made in the three priority subjects identified and selected for the first stage of work: a draft UN GTR on evaporative and crankcase emissions, a draft UN GTR on on-board diagnostics and an entire revision of UN GTR No. 2. He introduced a first draft of the new UN GTR on evaporative and crankcase emissions (GRPE-71-20) and highlighted some open issues under consideration such as reference fuels, reference to vehicle classes, list of acronyms and symbols, and ageing test procedure. He expressed the intention of the group to submit a proposal with an official symbol at the next GRPE session. He informed GRPE that the group also intended to submit a first draft of the new UN GTR on on-board diagnostics at the next GRPE session. He underlined the need to amend the existing mandate due to the limited time to complete all work. He requested an extension of the timeline until 2020 to be able to finish all topics within the current mandate going beyond the three priority subjects identified for the first stage of work (GRPE-71-21).

45. The expert from the United States of America noted the three different reference fuels and the maximum amount of ethanol to be set. The expert from IMMA recalled the priority agreed upon powered two wheelers, in particular two wheelers with petrol engines, to facilitate the coordination of work. He informed GRPE about some progress made on powered three wheelers. The Chair of GRPE stated that the issue of referencing vehicle classes defined in the Consolidated Resolution on the Construction of Vehicles (R.E.3) and the Special Resolution No.1 (S.R.1), as well as the use of the terms “light vehicle” and “light duty vehicle”, needed to be further discussed at the next GRPE session in January 2016.
