GRPE-82-07 | UN R83: Proposal for a new Supplement to 06 and 07 series of amendments Proposal addressing the conversion of NEDC road load to WLTP road load in cases where the former has already been determined.
GRPE-82-18 | UN R101: Justification for proposal for supplement to 01 series of amendment Proposal to amend Annex 7 – Appendix 2 paragraph 1., to provide the road load power calculation method that may be used
GRPE/2021/2 | UN R83: Proposal for a new Supplement to the 05 series of amendments Proposal to extend the option from the 06 and 07 to the 05 series of amendments allowing the calculation of road load values from those determined according to UN GTR No.15 (WLTP).

GRPE may wish to consider a proposal from the expert of OICA to amend one 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 one wrong cross reference in both the 06 and 07 series of amendments to UN Regulation No. 83. The same amendments are also proposed for the 01 series of amendments to UN Regulation No. 101.

GRPE-82-17 | UN R101: Proposal for Supplement to 01 series of amendments This proposal aims at harmonizing the text of UN Regulation No. 83 and UN Regulation No. 101. Furthermore, one error was 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 one wrong cross reference in the 01 series of amendments to UN Regulation No. 101. 1. Harmonization of UN Regulation No. 83 (Annex 4a, Appendix 7b, paragraph 1.) and UN Regulation No. 101 (Annex 7, Appendix 2, paragraph 1.); in Annex 7, Appendix 2, paragraph 1. Vehicles in general are not approved according to UN GTR No. 15, therefore the text phrase of UN R83 is recommended. 2. Correction of wrong reference to Annex 4 instead of Annex 7 of UN GTR No.15; in Annex 7, Appendix 2, paragraph 2.1.(b). 3. When copying the methodology from EU regulation, a ‘.’ was wrongly introduced instead of a ‘-‘ in the formula.
GRPE/2021/3 | UN R83: Proposal for a new supplement to the 06 and 07 series of amendments 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.
GRPE/2021/4 | UN R101: Proposal for a new supplement to the 01 series of amendments 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 the 01 series of amendments to UN Regulation No.101.

GRPE may wish to consider a proposal from the expert of OICA to correct an editorial error of exhaust after-treatment system monitoring requirement in the 07 series of amendments to UN Regulation No. 83.

GRPE/2021/5 | UN R83: Proposal for a new Supplement to the 07 series of amendments Proposal to correct an editorial error of exhaust after-treatment system monitoring requirement.

GRPE may wish to consider a proposal from OICA concerning reference fuels under the 05 and 06 series of amendments for the Type IV emissions test.

GRPE-82-08 | UN R83: Proposal for a new Supplement to 05 and 06 series of amendments Proposal to clarify that the E10 reference fuel may still be used at the worst case for the Type IV test.

GRPE may wish to review two proposals from Japan and the EU submitted to the March 2021 session of WP.29 to correct mistakes in the 00 and 01 series of amendments to UN Regulation No. 154, mainly stemming from improvements included in Amendment 6 to UN GTR No. 15.

GRPE-82-19 | UN R 154: Proposals to discuss issues raised on 01 series of amendment Proposal identifies 2 concerns: "Coasting“ - Coasting is defined in GTR 15 and UNR 154 and must be deactivated for testing, may raise concerns for the approval of many hybrid vehicles and for conventional vehicles with modern start stop systems. "Single roller dynamometer in 4WD operation“ - This combination is forbidden by GTR 15 and UNR 154 for the Type 1 test. There appears to be no reason for this ban (restraint systems must meet requirements for all configurations) other than an assumption that the configuration is not used for type 1 testing
GRPE-82-37 | UN R154 : Proposal to clarify concerns raised Proposal by the expert from OICA to clarify concerns about terms "coasting"and "Twin roller dynamometers in 4WD operation"
GRPE-82-37 | UN R154 : Proposal to clarify concerns raised Proposal by the expert from OICA to clarify concerns about terms "coasting"and "Twin roller dynamometers in 4WD operation"

GRPE may wish to consider a proposal from the expert of OICA to amend UN Regulation No. 101 to include a Shortened Test Procedure NEDC for PEVs.

GRPE-82-20 | UN R101: Proposal for a Shortened Test Procedure NEDC for PEV Proposes a shortened Test Procedure NEDC for PEV and alternative for conformity of procedure.
GRPE-82-21 | UN R101: Presentation for the proposal for a Shortened Test Procedure NEDC for PEV The presentation supports the proposal for a Shortened Test Procedure NEDC for PEV acc. to WLTP (including adding PEV COP procedure alternative).
GRPE/2021/2 | UN R83: Proposal for a new Supplement to the 05 series of amendments Proposal to extend the option from the 06 and 07 to the 05 series of amendments allowing the calculation of road load values from those determined according to UN GTR No.15 (WLTP).
