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.

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).
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.
