Proposal to:

• Insert a new para. 4 and 5 to the introduction of the 02 series and para. 5 and 6 to the introduction of the 03 series clarifying that the 03 series includes harmonised procedures and that amendments account for vehicles of categories X and Y equipped with Automated Driving Systems,
• Amend para. 2.1. to add ADS to general abbreviations,
• Amend para. 3.2.5., 3.2.31., 3.2.37., 3.5.8., 3.5.9., and 3.5.12. to include vehicle user terminology,
• Insert new para. 3.5.13. to 3.5.16. defining ADS road load determination mode, ADS testing mode, ADS user, and vehicle user,
• Amend para. 3.10.1., 3.10.4., and 3.10.20. concerning On-Board Diagnostic systems and malfunction indication to reference vehicle users and ADS,
• Insert footnote definitions referencing ECE/TRANS/WP.29/2026/153,
• Amend multiple paragraphs throughout Annexes A1, B4, B6, B8, C3, C4, and C5 to accommodate ADS operation,
• Insert new para. 4.2.1.8.6. to Annex B4 specifying ADS road load determination mode requirements for vehicles of categories X and Y,
• Insert new para. 2.4.2.7. to Annex B6 specifying ADS testing mode functional requirements,
• Amend various provisions concerning driver-selectable modes, reagent warning and inducement systems, and OBD monitoring to apply to vehicles equipped with ADS.

Proposal to introduce UBE_certified in the templates for the information document and WLTP test report under Annex A1 to UN R154. The proposal requests clarification on the number of significant figures for Usable Battery Energy of the vehicle at certification in the information document and seeks confirmation that the test result needs to be within 2 per cent of the declared value in the WLTP test report.

Document presents an overview of brake force distributions (BFD) installed on light commercial vehicles (LCV) across different OEM applications and vehicle categories, showing front axle and rear axle percentage distributions for vehicles of category N₁ and N₂ with various gross vehicle weights ranging from 3.5 to 5.5 tonnes.

The report describes the final status of Amendment 2 to UN GTR No. 24 covering laboratory measurement of brake emissions, including hardware requirements (brake dynamometer, enclosure design, fixtures, temperature measurement, sampling tunnel and plane), the WLTP Brake cycle test procedure with quality checks and temperature specifications, cooling air conditioning specifications, cooling adjustment section procedures for different brake categories, bedding and emissions measurement sections, and PM mass concentration measurement methodology validated through an Inter-laboratory Study across multiple testing facilities.

Proposal to amend GRPE/2026/53, establishing a new UN Regulation transposing UN GTR No. 24 for the approval of non-original and identical replacement brake parts (pads, linings, discs, drums) for vehicles of categories M₁, N₁, and N₂ with maximum mass between 3.5 and 5 tonnes.

Proposal to amend GRPE/2026/29, establishing a globally harmonized laboratory methodology for measuring brake particulate matter (PM) and particle number (PN) emissions from heavy-duty vehicles of categories M₂, M₃, N₂, N₃, and O₃, O₄.

Proposal to establish a new UN Regulation on laboratory measurement of brake emissions for heavy-duty vehicles of categories M₂, M₃, N₂ and N₃ using friction braking. The regulation defines test procedures, brake emissions groups, compliance requirements with emission limits for PM10 and SPN10, type approval processes, conformity of production requirements with statistical sampling procedures, and technical specifications for test systems including brake dynamometers, brake enclosures, sampling tunnels, and particle measurement instrumentation.

Proposal to amend GRPE/2026/31 revising the methodology for measuring brake particle emissions from light-duty vehicles.
