Proposal to insert a new introduction section accounting for vehicles of categories X and Y equipped with an Automated Driving System (ADS), amend footnote 1 to reference the Consolidated Resolution on the Construction of Vehicles (R.E.3.), document ECE/TRANS/WP.29/78/Rev.8, and amend para. 6.1.5. to clarify that the exemption for sensors and driver assistance systems does not apply to vehicles of categories X and Y or automated driving systems unless the ADS performance of the Designated Driving Task is not affected.
Agenda for the 22nd session of the CLIV IWG, scheduled for 22 October 2026. The session will address opening remarks, introduction of new members, adoption of the agenda, recap of the France 21st meeting session, discussion on the 00 series for a door logic regulation, definition and discussion on indirect plus and direct systems and their effectiveness, justification and explanation for the GRSP formal document UN Regulation, and any other business.
Provisional agenda for the 52nd session of the IWVTA Informal Group scheduled for November 12, 2026 in Paris. The session will address election of a new Chair, adoption of the agenda and 51st session report, highlights from the 199th WP.29 session, amendments to UN R0 series, contradiction between transitional provisions in UN R22 and Revision 3 of the 1958 Agreement, proposed amendments to Guidelines on Transitional Provisions, IWVTA awareness and promotion, extension of mandates, and DETA scheme implementation.
The document outlines the process for developing UN R40.03. It specifies that EPPR7302 (IMMA) draft proposal for UN R40.03 should serve as the basis for discussions and drafting of regulatory texts and provisions. Comments should be submitted in advance, preferably one week before the meeting. Regulatory texts and provisions will be discussed and drafted based on comments and proposals submitted before or during the meeting.
Draft agenda for the first session of the Task Force on the 03 series of amendments to UN R40, scheduled for 9 October 2026. The session will include welcome remarks, introduction of participants, adoption of the draft agenda, and introduction of the Task Force establishment proposal. IMMA will present an overview of the 02 series of amendments based on UN GTR No. 2. The Task Force Co-Chairs will introduce a proposal on conducting discussions on the 03 series, addressing the regulation progressively with Co-Chairs defining specific sections for analysis at each meeting. The basis for discussions is the draft R40.03 submitted by IMMA. Future Task Force sessions are scheduled before EPPR sessions in November 2026, January 2027, February 2027, and June 2027.
Proposal to improve and correct the procedure for laboratory measurement of brake emissions for light-duty vehicles of categories M₁ and N₁. The regulation establishes requirements for brake particle emission testing including test setup, the WLTP-Brake cycle test procedure, cooling air adjustment, brake bedding, and emissions measurement sections. Compliance is demonstrated through brake corner emission family testing with PM₁₀ and SPN₁₀ measurements. Conformity of production is verified through periodic sampling and statistical evaluation. Type approval requires demonstration that whole vehicle brake emissions calculated from individual axle emissions multiplied by friction braking share coefficients do not exceed limits of 3 mg/km PM₁₀ for M₁ and N₁ vehicles and 5 mg/km for N₁ Class III and N₂ vehicles.
Progress report on development of a Global Technical Regulation for brake emissions testing. The document presents bracketed parameters under development including brake test temperature measurement, sampling plane positioning, brake enclosure dimensions, payload factors, and emission factor calculations. It outlines the structure of the informal document based on UN R179, defines endurance braking systems and electric regenerative braking, presents C-factor methodology for primary and secondary endurance braking, and describes conformity of production procedures and next steps including removal of brackets and round-robin data analysis.
