GRPE-79-10 | UN R83: Request for interpretation of Supplement 6 to the 07 series of amendments (GRPE/2017/2) OICA request for clarification on the interpretation of Supplement 6 to the 07 series of amendments to UN R83 which enables the use of compliance assessments of vehicles with a reference mass less than 2,610 kg for the purposes of extending the type approval to special purpose vehicles (including armoured ones) having a reference mass exceeding 2,840 kg.

GRPE-79-11 | UN R101: Updated information on OICA proposal Update on the status of work regarding the transition from NEDC to WLTP, particularly pending the transposition of GTR 15 into one or more UN Regulations under the 1958 Agreement.

GRPE-79-15 | UN R83: Proposal for Amendment to the 07 series - Definition of Permanent default Proposal to clarify "permanent default" and "limp-home mode" in UN R83.

GRPE-79-16 | UN R83: Proposal for Amendment to the 07 series - Definitions to erase fault codes Proposal to amend current definitions to allow fault code erasing in cold regions (< -7°C) and high altitude (> 2440m), harmonizing the definitions with those used in China and the United States.

GRPE-79-17 | UN R83: Proposal for Amendment to the 07 series - Introduction of Special denominator Proposal to allow for the use of use special denominator conditions for certain components or systems. The current definitions of the specific denominators are based on engine/aftertreatment system combinations designed as one TWC for gasoline vehicles and DOC, DPF and SCR respectively NSC for diesel engines. Upcoming emission requirements will bring up additional aftertreatment components like Gasoline Particulate Filters (GPF) or new designs with more than one SCR catalyst. Such new systems or catalyst combinations might require specific conditions to enable the monitoring, especially when their purpose is designed for such conditions.

GRPE/2017/2 | Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 Proposal to allow the use of compliance assessments of vehicles with a reference mass less than 2,610 kg in extending the type approval to special purpose vehicles (including armoured ones) having a reference mass exceeding 2,840 kg. This proposal would align UN R83 with provisions of European Directive 2007/46/EC.

GRPE/2019/10 | UN R115: Proposal for a new Supplement This proposal amends UN Regulation No. 115 to list conditions, especially with regard to retrofit systems, to be met by indirect and direct injection vehicles to be considered as belonging to the same vehicle family. Gasoline direct injection vehicles which operate in indirect gas injection mode should be listed in the same family as indirect gasoline injection vehicles, as the applied gas injection technology is the same and provided that at least one such vehicle is tested as parent vehicle according to the requirements of this Regulation.

GRPE/2019/11 | UN R85: Proposal for a new Supplement Proposal to allow an alternative test method to “set the charge air cooler outlet temperature during bench test to temperature which was observed by vehicle test and corrected to the reference temperature specified in paragraph 5.2.1.” of Annex 5. This alternative method is well recognized in SAE J1349.
