Proposal to integrate exemptions for special purpose vehicles into UN R83.

Proposal to introduce the possibility to switch OFF rear position lamps and other lamps when ambient light conditions outside the vehicle are above 7,000 lux in order to avoid unnecessary fuel consumption (in alignment with UN R48 wording).

Proposal to allow measurement equipment compliant with the technical requirements of UN R154 to be used for testing under UN R83.

Proposal to correct the recursive formula of the 05, 06 and 07 series of amendments to UN R83 in the procedure for verifying the conformity of production and to align the approval certificate in 06 and 07 series of amendments with recent changes to regulation UN R24.

Annex 4A-Type 1 tests include references to daytime running lamps and rear position and other lamps. In line with UN R48 and its 08 series of amendments which would permit switching off of rear position and other lamps when ambient light conditions are above 7,000 lux to avoid unnecessary fuel consumption, this proposal would permit ambient lighting during dynamometer operation above this threshold.

20. The representative from OICA introduced GRPE-85-18-Rev.1, GRPE-85-19-Rev.1 and GRPE-85-20-Rev.1. proposing to take the new 7000Lux criterion for Daytime Running Lamps (DRL), as stipulated in the 08 Series of Amendments to UN Regulation No. 48, into account in the 06 and 07 series of amendments to UN Regulation No. 83, the 01 Series of Amendments to UN Regulation No. 101 and the original, 01, 02 and 03 series of amendments to UN Regulation No. 154.

21. The representative from the Netherlands requested some clarifications on the potential quantification of CO2 emissions differences between rear lights on or off. The representative from the EC requested any information on the meaning of 7000 Lux and the share of typical driving below and above this threshold. The representative from OICA said no numbers about potential CO2 emission differences were available at the time of the meeting. He also clarified that 7000 Lux condition corresponded to dusk conditions or very cloudy conditions. He agreed to prepare more evidence for future GRPE sessions.

22. The representative from the EC briefly explained that such rear light deactivation system was being considered to be included in eco-innovation lists of the EU, and therefore further discussions were needed before sharing a position on this proposal with GRPE.

23. The Chair agreed with the concern from the representative from OICA that a consistent approach was necessary for all laboratories performing the tests prescribed in UN Regulations Nos. 83, 101 and 154, and insisted that double counting of potential emissions reduction benefits should be avoided. He invited the representative from OICA to revise the proposals to include possible cases in square brackets for GRPE deliberations during the next session of GRPE, and to provide more evidence on the expected impact on emissions differences with the rear light on and off, and the shareshare of driving under each light conditions (below and above 7000 Lux). GRPE supported the approach proposed by the Chair.

Proposal to permit use of equipment conforming to UN R154 for testing under UN R83 (and by extension to UN R101 which references UN R83).

13. The representative from OICA introduced GRPE-85-10 proposing to allow for the specification of the test equipment allowed for UN Regulation No. 154 to also be allowed in the 05, 06, 07 Series of Amendments to UN Regulation No. 83. The representatives from France, Germany, The Netherlands, Spain and Sweden supported the proposal. The Chair requested the representative from OICA to prepare a working document for forthcoming sessions of GRPE.

Proposal to correct the recursive formula of the 05, 06 and 07 series of amendments to UN Regulation No. 83 in the procedure for verifying the conformity of production requirements if the production standard deviation given by the manufacturer is either not satisfactory or not available.

10. The representative from OICA introduced GRPE-85-09 and GRPE-85-15 proposing to correct the recursive formula calculating pass/fail criteria of CoP in the 05, 06, 07 Series of Amendments to UN Regulation No. 83 and the 02 and 03 Series of Amendments to UN Regulation No. 154. The representative from the EU informed GRPE that the proposal did not impact the EU as they use a different approach to pass/fail criteria of CoP tests. The representative from India supported the proposals and asked whether UN GTR No.15 should also be amended in a similar way. GRPE agreed to consider GRPE-85-09 as a working document in forthcoming sessions of GRPE.

11. The secretariat proposed to adopt GRPE-85-15 and to include it in revisions to ECE/TRANS/WP.29/2022/41 and ECE/TRANS/WP.29/2022/42 to be considered by WP.29 and AC.1 in March 2022. He prepared GRPE-85-45 and GRPE-85-46 respectively. The representative from Japan supported the proposals and added that they were flexible on the timing of implementation of such proposals.

12. GRPE adopted GRPE-85-45 and GRPE-85-46 as ECE/TRANS/WP.29/2022/41/Rev.1 and ECE/TRANS/WP.29/2022/42/Rev.1 respectively and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their March 2022 sessions as draft 02 and 03 series of amendments to UN Regulation No. 154 respectively.

Proposal to introduce provisions specific to special-purpose vehicles.

7. The representative from OICA introduced ECE/TRANS/WP.29/GRPE/2022/2 and ECE/TRANS/WP.29/GRPE/2022/8 proposing to integrate requirements for Special Purpose Vehicles (SPVs) in the 06 and 07 series of amendments to UN Regulation No. 83 and Consolidated Resolution on the Construction of Vehicles (R.E.3). The representative from Spain proposed clarifications on ECE/TRANS/WP.29/GRPE/2022/8 to be included in any revised version (GRPE-85-48), and requested clarifications on ECE/TRANS/WP.29/GRPE/2022/2, as supported by the representative from Sweden.

8. The representative from Australia asked whether similar provisions should also be included in UN Regulation No. 154. The representative from France supported the proposals and requested to be cautious about exempting from Conformity of Production (CoP) requirements. The representative from the European Union, as supported by the representative from the Netherlands, needed a review on the deletion of the extension rule and requested additional time to consider the proposals.

9. The representative from OICA explained the rationale for the proposals, mainly to ease the way in some markets where a very limited number of vehicles falling under the definition of SPVs are registered, and where identifying vehicle to perform CoP tests would be very challenging. The representative from OICA also agreed for a delayed consideration of the proposals, and he proposed to improve the documents for a consideration in forthcoming sessions of GRPE.

Proposal from GRPE to extend the acceptable reference fuels and road load determination methodologies and clarify crankcase pressure measurement and four-wheel drive vehicle tests.

Proposal from GRPE to extend the acceptable reference fuels and road load determination methodologies and clarify crankcase pressure measurement and four-wheel drive vehicle tests.

Proposal from GRPE to extend the acceptable reference fuels and road load determination methodologies and clarify crankcase pressure measurement and four-wheel drive vehicles tests.

69. The Chair introduced GRPE-83-35 as revised list of priorities to be shared with WP.29. The representative from the EC called for prior consultation within GRPE before including new element in the priority list.

70. The representative from Japan stated that carbon neutrality was now a crucial issue in the country and required the issue of life cycle analysis to be considered by GRPE as candidate to be included in the priority list, as was already the case in the GRPE emission items list (GRPE-80-04-Rev.1). the Chair agreed to consider this at the next session of GRPE in November 2021.

Proposes
• a technically neutral description for the measurement of crankcase pressure in Type III Test.
• the option to test a four-wheel vehicle without being forced to use an artificially created two-wheel drive
mode.

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.

Definition and exemptions for special purpose vehicles are necessary. Possible amendments have been shown for
• New definitions in R.E.3 and
• Requirementemissiontothegreatestextent,
• ExemptionsfordriverinducementsystemandCOP/in-serviceconformity.

14. Given time constraints, the Chair proposed to receive GRPE-83-16 under agenda item 16 if time allows.

72. As the time allowed for the meeting had expired, the Chair proposed to receive the presentation from the expert from OICA on GRPE-83-16 during the January 2022 session of GRPE. GRPE agreed to this proposal.

Proposal to correct an error found in the formulas used for the calculation of a NEDC road load values from those determined according to UN GTR No. 15 (WLTP) and a cross reference in both the 06 and 07 series of amendments to UN Regulation No. 83.
