Agenda Item 3. (b)
Light vehicles: Global Technical Regulation No. 15 on Worldwide harmonized Light vehicles Test Procedures (WLTP)

14. The Vice-Chair of the IWG on WLTP reported on the progress made by the group on each of the tasks of the Phase 2 activities (GRPE-74-11).

15. The drafting coordinator of the IWG on WLTP presented ECE/TRANS/WP.29/GRPE/2017/7 on amendments to UN global technical regulation (GTR) No. 15 on WLTP. He also presented GRPE-74-02-Rev.1 introducing some changes to ECE/TRANS/WP.29/GRPE/2017/7 and he referred to GRPE-74-03-Rev.1 as a consolidated version of both documents. He introduced the technical report on the further development of WLTP (GRPE-74-05). He clarified that the technical report was a consolidated version combining all phases of the development of GTR No. 15 up to now.

16. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/7 as amended by Annex V to this report and requested the secretariat to submit it to WP.29 and the Executive Committee of the 1998 Agreement (AC.3) for consideration and vote at their June 2017 sessions as draft Amendment 2 to GTR No. 15 on WLTP. GRPE also adopted the technical report (GRPE-74-05) as reproduced in Addendum 1 to this report and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions.

17. The expert from EC presented ECE/TRANS/WP.29/GRPE/2017/3 on a draft new GTR on evaporative emission test procedure for WLTP (WLTP EVAP). He clarified that the current proposal focuses on the evaporative emissions that can occur during parking events, so running losses and refuelling emissions are out of the scope for the time being. He explained that the test procedure for sealed fuel tank systems will be introduced at a later stage. He introduced the technical report on the development of the draft new GTR (GRPE-74-04).

18. The expert from ETRMA presented GRPE-74-10 to highlight that emissions from tyres should be excluded from the test procedure in the draft new GTR on WLTP EVAP. He explained that tyres should be removed at the stage of vehicle preparation, since they are not part of the fuel storing system and they may add some uncertainty to the test.

19. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/3 and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions as a new draft GTR on evaporative emission test procedure for WLTP (WLTP EVAP). GRPE also adopted the technical report (GRPE-74-04) as reproduced in Addendum 2 to this report and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions.

20. The expert from EC presented a status report on the WLTP Task Force dealing with the transposition of WLTP into the 1958 Agreement (GRPE-74-20). He informed that the Task Force had not met yet, but the first meeting would take place in February 2017. For the [adaptation] of the 1958 Agreement to include WLTP, he explained the intention was to follow a two-step approach: first, introduction of transitional provisions in Regulations Nos. 83 and 101 (see paras. 11-13 above); second, full transposition of GTR No. 15 into new Regulations under the 1958 Agreement. He recalled previous presentations by EC and the Secretariat on possible ways to structure these new Regulations (GRPE-72-18 and GRPE-73-26).

21. GRPE agreed to further discuss the transposition of WLTP into the 1958 Agreement at the next GRPE session on the basis of the work carried out by the WLTP Task Force dealing with this topic.

22. GRPE acknowledged the progress made by the IWG on WLTP and noted the request for a meeting room for one day during the GRPE week in June 2017.
