| GRPE | Session 83 | 1-4 Jun 2021 |
7. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2021/10 and GRPE-83-15 extending the acceptable reference fuels and road load determination methodologies and clarifying crankcase pressure measurement and four-wheel drive vehicles tests in the 05, 06 and 07 series of amendments to UN Regulation No. 83. The representative from the UK requested further details on the road load determination proposal. The representative from OICA explained it would reduce testing burden to be able to use road load determination approaches used for UN GTR No. 15 and UN Regulation No. 154. The representative from Spain raised concerns about formulation in ECE/TRANS/WP.29/GRPE/2021/10 and GRPE-83-15 which were corrected during the session, as reflected in Annexes IV, V and VI to the session report. 8. GRPE requested the secretariat to submit Annexes IV, V and VI to WP.29 and AC.1 for consideration and vote at their November 2021 sessions as draft Supplement 15, 17 and 14 to the 05, 06 and 07 series of amendments to UN Regulation No. 83 respectively. |
