In ECE/TRANS/WP.29/2018/147, paragraph 14.3., amend to read:
“14.3. Alternative procedure …
The road load coefficients to be used shall be those for vehicle low (VL). If VL does not exist then the VH road load shall be used. VL and VH are defined in point 4.2.1.1.2. of Annex 4 of Amendment 4 to UN GTR No. 15. The dynamometer…”

In ECE/TRANS/WP.29/2018/148, paragraph 14.3., amend to read:

4.7. | Consideration of draft amendments to existing UN Regulations submitted by GRPE

82. The World Forum considered the draft amendments under agenda items 4.7.1 to 4.7.5 and recommended their submission to AC.1 for voting, with the following exception: documents ECE/TRANS/WP.29/2018/48/Add.1 and ECE/TRANS/WP.29/2018/49/Add.1 under agenda items 4.7.3 and 4.7.4 had been modified in June 2018 by GRPE, and therefore, should not be taken into consideration for vote at this session.

4.7.3. | Proposal for Supplement 11 to the 06 series of amendments to UN Regulation No. 83 (Emissions of M1 and N1 vehicles)
3. (a) | Light vehicles: Regulations Nos. 68, 83, 101, and 103

7. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/13 clarifying the basis of the petrol tank capacity restriction for mono fuel gas vehicles. GRPE adopted the proposal.

9. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/15 and ECE/TRANS/WP.29/GRPE/2018/17 aimed at adapting the provisions in UN Regulation No. 83 and UN Regulation No. 101 to allow the usage of WLTP-based Ki and Deterioration Factor (DF) factors as well as On-Board Diagnostics (OBD) demos. The experts from EC and UK proposed minor corrections to ECE/TRANS/WP.29/GRPE/2018/15 that GRPE adopted as reproduced in Annex VI. GRPE also adopted ECE/TRANS/WP.29/GRPE/2018/17.

10. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/18 aimed at modifying the Constant Volume Sampling system temperature sensor time response requirement in UN Regulation No. 83. The Chair of GRPE requested clearer provisions to align with the work performed under the IWG on WLTP. The Expert from OICA presented informal document GRPE-77-31 amending ECE/TRANS/WP.29/GRPE/2018/18. GRPE adopted the proposal as reproduced in Annex VII.

12. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2018/13, Annexes IV, VI and VII and Addendum 1 to the report to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions as draft Supplements 2, 1, 12, 12 and 18 to the 03, the 04, the 05, the 06 and the 07 series of amendments to UN Regulation No. 83 respectively.

3. (a) | Light vehicles: Regulations Nos. 68, 83, 101 and 103

11. The expert from EC presented GRPE-76-32 proposing to amend the definitions for bi-fuel vehicles and align these definitions with those in UN Global Technical Regulation (UN GTR) No. 15. GRPE supported the intention of the proposal.

12. GRPE agreed to reconsider at the June 2018 session GRPE-76-03, GRPE-76-04 and GRPE-76-32. GRPE requested the experts from OICA and EC to combine the documents in one formal document.
