The deadline for the submission of official working documents for this session is 9 October 2017.
29. The expert from OICA presented ECE/TRANS/WP.29/GRPE/2018/5 as amended by GRPE-76-23 proposing a solution for the concern raised by the expert from UK in GRPE-75-13 and corrects a long standing error in a formula shown by OICA in GRPE-75-12. GRPE adopted the proposal as reproduced in Annex VII and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2018 sessions as draft Supplement 8 to UN Regulation No. 85.
30. The expert from Italy introduced GRPE-76-02 on the need to update UN Regulation No. 115 and the need to introduce a reference to WLTP instead of emission tests performed on the basis of the former test cycle (New European Driving Cycle (NEDC)). GRPE agreed with Italy that performing a back to back test on the basis of the NEDC test cycle would not make sense if the original type of vehicle would be type-approved on the basis of WLTP. Recalling para. 1.5 of UN Regulation No.115, which requires the modified vehicle to fulfil all the provisions of the Regulation for which the type approval has initially been granted, GRPE confirmed that the Type I test should be performed with the same cycle used during the approval of the original type of vehicle.
31. GRPE invited the expert from Italy and interested experts to consider developing a proposal for amendments to UN Regulation No. 115. The experts from AEGPL and IANGV/NGV Global volunteered to contribute to the work proposed by the expert from Italy.
