Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83:
Adopted proposal to amend provisions on Selective Catalytic Reduction (SCR) warning and inducement systems, including reagent tank capacity and level specifications.

Vehicle emission after-treatment system tampering and manipulation-Request for guidance on standardisation of eOBD data related to the urea system sensor

Series of proposals from the WLTP informal group to improve and clarify the text of GTR 15 on light vehicle emissions, amending the contents of document GRPE-76-26/Rev.1.

Amendment 2 addresses the evaporative emission family definitions and improves Type 4 test procedures with regard to test equipment requirements and calibrations, evaporative emission measurement enclosures, and use of variable volume SHED facilities.

Explanation of the proposal (GRPE/2018/19) to align UN R24 (Compression Ignition Engines – Emission of Visible Pollutants – Power Measurement) with UN R85 with regard to correction factors.

AEGPL views on the proposal to align Regulation No.115 to the new WLTC test cycle, defined in the GTR 15 and in the Commission Regulation (EU) 2017/1151 and later modifications.

OICA changes to its proposal to modify the Constant Volume Sampling system temperature sensor time response requirement.

Proposal to clarify the meaning and use of “peripheral devices”.

Revised proposal to amend provisions on Selective Catalytic Reduction (SCR) warning and inducement systems, including reagent tank capacity and level specifications. This proposal updates the previous document GRPE-76-34 (which updated the formal proposal GRPE/2018/7).

This document addresses the need to align Regulation No.115 to the new WLTC test cycle, defined in the GTR 15 and in the Commission Regulation (EU) 2017/1151 and later modifications.

Proposal to introduce an alternative test method for measuring charge-air-cooled engines net power for use with high power engines of those. The proposal would “decrease the charge air cooler outlet temperature by the same amount that the ambient conditions for the vehicle test varied from the standard temperature” in line with SAE J1349, “9.3 Application of Vehicle Transient Data to Net Power Test.”

Presentation proposing to amend obsolete footnotes regarding the particulate number emissions limits applicable depending upon the reference fuel selected for the test procedure.

Proposal to clarify the draft text that would explicitly specify requirements related to the selection of driving modes for testing of Off-Vehicle Charging Hybrid Electric Vehicles (OVC-HEV) with a mode selection switch.

Proposal for changes to the draft new Supplement to the 06 and 07 series of amendments to UN Regulation No. 83.

Proposal to align UN R24 (Compression Ignition Engines – Emission of Visible Pollutants – Power Measurement) with UN R85 with regard to correction factors.

Proposal to modify the Constant Volume Sampling system temperature sensor time response requirement.

Proposal to allow the usage of WLTP-based Ki and Deterioration Factors (DF) as well as On-Board Diagnostics (OBD) demos under UN R101. The proposal allows the use of the more robust WLTP and eases testing burdens by allowing manufacturers to use WLTP test results for UN R101.

Proposal to allow the usage of WLTP-based Ki and Deterioration Factors (DF) as well as On-Board Diagnostics (OBD) demos under UN R83. The proposal allows the use of the more robust WLTP and eases testing burdens by allowing manufacturers to use WLTP test results for UN R83.

Proposal to explicitly specify requirements related to the selection of driving modes for testing of Off-Vehicle Charging Hybrid Electric Vehicles (OVC-HEV) with a mode selection switch.

Proposal to explicitly specify requirements related to the selection of driving modes for testing of Off-Vehicle Charging Hybrid Electric Vehicles (OVC-HEV) with a mode selection switch.

Proposal to clarify the fuel tank capacity restriction for mono-fuel gas vehicles. The definition of “mono-fuel gas vehicle” was slightly amended between the 06 and the 07 series of amendments to UN R83. This proposal aims to align the definitions across both series in order to avoid divergent interpretations.
Although the reference to a 15 liters tank has always been understood to refer to the nominal capacity of the tank, the use of the term “nominal capacity” in UN GTR No. 19 in several places other than the definition of “mono-fuel gas vehicle” can lead to other interpretations of the definition. The word “nominal” should therefore be inserted into the definition in both series of amendments.

Proposal to align UN R132 with the proposed 05 series of amendments to Regulation No. 96.
