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.

Proposal to clarify the scope of Regulation 85 concerning electric drivetrains.

Illustration to support proposals explained in document GRPE-85-13.

Proposal to correct the recursive formula 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.

Proposal to harmonize:

• Requirements for the determination of CO2, fuel and electric energy consumption of the discharge requirement for OVC-HEV with an operating mode switch with its stop criterion.
• Preconditioning requirement (Annex 9, determination of electric range) and UN R83 (Annex 14, provisions for emissions test procedures for HEV).

The use of test fuels is permitted for certification testing of gaseous and particulate pollutants and power/smoke testing in Europe. However, other countries that have adopted and referenced UN R24 may not allow this. This proposal would permit the use of the same test fuel in cases where the testing for emission of gaseous and particulate pollutants is conducted at the same time as the testing under UN R24.

Proposal to permit the use of hydrogen (H2) as fuel for type approval of heavy-duty vehicles.

Proposal aims at permitting the use of the latest reference fuels for evaporative emissions approval of vehicles

Introduces a shortened test procedure for PEVs as well as an update of the COP test procedure in order to align with proceeding and procedures described in UN R154.

Consolidates the existing text of the Regulation with that of the reference document adopted by GRPE 82nd session

Proposes to allow the use of nitrogen as batch gas for FID fuel gas and introduces the requirements for humidity sensors.

Proposal to correct and clarify the text and to introduce linearity requirements for humidity sensors to address humidity content measurement for the calculation of the specific exhaust emission.

Proposal to align provisions in paragraph 7 and Annex 6.

Text prepared by IWG on EVE based on GRPE-82-27.

Proposal to introduce particle number requirements and limits for Level 1B. The proposal also aligns the particulate measurement procedures with changes introduced in GTR No 15 Amendment 6 and other adaptations to technical progress.

Proposal to ensure that Level 2 is the latest version of this Regulation and is therefore subject to mutual recognition under the 1958 Agreement, given that there is a concurrent proposal to for an 02 series of amendments which introduces particle number requirements and limits for Level 1B. This proposal for a 03 series of amendments also aligns the particulate measurement procedures with changes introduced in GTR No 15 Amendment 6 as well as other adaptations to technical progress.

Proposal to introduce provisions specific to special-purpose vehicles.

Proposal to introduce provisions for the approval of a vehicle type with an approved engine with regard to their emission of pollutants, and the reporting of the CO2 emissions and fuel consumption for type approval of vehicles with a reference mass exceeding 2,380 kg but not exceeding 2,610 kg.

Proposal to align UN R24 with to align the UN R85 and ISO 1585:2020.

Proposal to align UN R85 with ISO 1585:2020.

Proposal to expand the scope to include more vehicle types (higher-powered three-wheeled vehicles) and to introduce additional fuel types to be included in the test procedure.

Text prepared by IWG PMP for a new Consolidated Resolution concerning the test procedure for the measurement of ultra-fine particle emissions from Heavy Duty engines.
