Proposal for updates to the text in document GRPE/2022/6 from the EPPR informal group.

Proposal for updates from the EPPR informal group to the draft text of document GRPE/2022/7.

Recommendation to pursue a GTR specific to heavy-duty vehicles derived from the work on the light vehicle EV battery durability GTR.

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.

Annex 5 procedures 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.

Annex B6 procedures include references to 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.

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 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.

Summary report discussing implications for developing a commercial passenger bus event data recorder (EDR) standard, focusing on the feasibility of equipping heavy vehicle event data recorders (HVEDRs) in motorcoaches, buses and school buses.

TF TA will address the tyres abrasion performance by determining a standardized measurement method which will allow for the quantification of the microplastic emissions in the environment. At the same time, the TF TA will investigate the correlation between abrasion rate and durability and consider the inclusion of both abrasion rate and durability

Text as revised during the 49th (February 2022) EPPR informal group session.

Text as approved by GRPE to introduce a modified WMTC test cycle procedure and a new vehicle classification for low-powered vehicles, such as commonly used in India and China.

Proposal as endorsed by GRPE for a new Consolidated Resolution concerning Exhaust Ultra-Fine Particle Number Measurement For Heavy Duty Engines.

Proposal to allow for the usage of the reference fuel required for emission testing when the manufacturer applies for UN R85 and/or UN R49 type approval at same time.

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

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.

Proposal to allow measurement equipment compliant with the technical requirements of UN R154 to be used for testing under 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 integrate exemptions for special purpose vehicles into UN R83.

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

Proposal to explicitly permit the usage of the reference fuel required for emission testing when the manufacturer applies for
UN R24 and/or R49 type approval at same time.

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.

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. The preconditioning requirement is also harmonized between the 01 series of amendments of UN Regulation No. 101 (Annex 9, determination of electric range) and 06 and 07 series of amendments of UN Regulation No. 83 (Annex 14, provisions for emissions test procedures for HEV).

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 update the original text of UN R154 with corrections and clarifications identified during the development of the 02 series of amendments.

Proposal to update the 01 series of amendments with corrections and clarifications identified during the development of the 02 series of amendments.

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

Proposal from GRPE 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 R85 with ISO 1585:2020 and clarify the scope with regard to electric drive trains.

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.

Presentation by Transdev Group.

Presentation of outcomes from ADAC tyre testing programs.

Presentation on how to harmonize the requirements of the 06 and 07 series of amendments to UN R83, the 01 series of amendments to UN R101 and the original, 01, 02 and 03 series of amendments to UN R154 respectively, and to ensure consistent type-approval test conditions with the introduction of the 08 series of amendments to UN R48.

Also applicable for R85

Proposal:

1. To ensure and promote a high level of protection for the environment and human health. The underlying purpose of paragraph 3.5.7, when read in conjunction with paragraph 5.3.4, is to ensure a high level of protection for
   environment and human health. In making clear and encouraging the proper application of these provisions, this amendment furthers the aims sought to be achieved through paragraphs 3.5.7 and 5.3.4 of the Regulation.
2. To ensure and promote consumer confidence in the quality of vehicles subject to UN GTR No. 15. Given the widespread use of defeat devices (justified or otherwise) in the preceding years, consumer confidence in regulatory regime’s ability to conform with its underlying purpose has
   dwindled. This amendment makes clear and encourages the proper application of the text of the Regulation with respect to defeat devices. In doing so, consumers will be more confident in proper application of the provision.
3. To promote legal certainty. It is recognised that it is for the members of the WP.29 to interpret the provisions of Regulations at a national level. However, it is critical that Regulations of the WP.29 are clear and precise. The addition of the term “immediate” as an adjective to the term “damage” in subparagraph (a) to section 3.5.7 would make it clear that delayed or gradual damage to the engine does not justify the use of a defeat device.
