Draft minutes of the 49th session of the Task Force on Tyre Abrasion (TFTA), held June 3rd, 2026 (9:00–12:00 CET). Previous meeting minutes were approved. Action item TA-48-1: ETRTO to check feasibility to upload acceleration calculation examples on TFTA wiki. ETRTO confirmed feasibility assessment completed; example files could be moved to TFTA wiki with a disclaimer that TFTA is not responsible for example content. Action item TA-49-1: ETRTO will prepare disclaimer to be reviewed and validated by TFTA during 50th session. Agenda adopted. ETRTO presented comments on updated Gantt prepared by UTAC per document TA-49-03. TFTA agreed to evaluate data analysis per tyre segment when data available. JASIC requested more time to review and provide feedback next session. ETRTO and JATMA tyre manufacturers ready to make selected tyres available; first orders and deliveries started last week of May. Training session on best practices organized 2nd half of June. Action item TA-48-2: SWG on data assessment to redefine scope and mandate. SWG leader presented amendment proposal per document TA-49-02. TFTA agreed with SWG scope and mandate per TA-49-02/Rev.1. ETRTO stated mileage potential work should address all TFTA members and tyre manufacturers associations at UN level. JRC studying tread depth divided by abrasion index approach. Topic readdressed next TFTA. ETRTO noted test campaign running; final results expected Q4 2026 including 2nd set Normal and 3PMSF temperature behavior tests and pressure impact test. Action item TA-49-2: EC and JRC will reflect by next TFTA session how annex 4 would be impacted considering C2 tyres. TFTA co-chair suggested extraordinary brainstorming session end September/beginning October 2026 for C3 tyre abrasion test method development. Next meetings: 50th session July 6 (9:00–12:00 CET); 51st session August 25 (9:00–12:00 CET).

The Tyre Abrasion Task Force has completed tyre selection for the Confirmation plan 2026 and informed candidate test facilities. Tyre availability and shipments remain ongoing. Data collection and compilation for data assessment awaits test commencement. The SWG on Data Assessment has agreed to transfer discussions regarding exclusion criterion for high variability tyres and acceleration corrections to TAPP upon its resumption of meetings.

The document presents reflections on equivalence criteria for C2 tyres under Annex 4. C1 and C2 protocols are expected to remain very similar, with most changes having no impact on ALI and facility correlation. Key differences include tyre load and inflation pressure specifications. The main hypothesis states that if final C2 methods remain closely aligned to C1 methods, the existing equivalence framework for C1 could be maintained and extended to C2 testing, with already equivalent facilities receiving automatic equivalence or minor validation, and new facilities requiring amendment of Annex 4 to accept a mix of C1 and C2 tyres for demonstration of equivalence.

Draft agenda for the 43rd Session of the Informal Working Group on Automotive Life Cycle Assessment (IWG on A-LCA) meeting on July 6th, 2026, from 11:30~14:30 CET. The agenda includes welcome and introduction, adoption of the agenda and last meeting minutes, decision on Document Package, decision on Open Items, decision of the latest document, next steps including Report to GRPE and Revision of ToR, and closing.

The agenda includes adoption of EPPR-74-01 and EPPR-73-04, transposition of UN-GTR 2 into UN-Regulation 40 across Euro 3, 4, and 5 emission levels using documents GRPE-93-07-Rev.1, GRPE-92-12, GRPE-92-13, GRPE/2025/22, GRPE-93-26, EPPR-73-02, and EPPR-73-03, maximum power determination discussions using EPPR-22-15 through EPPR-59-04, battery electric vehicle range determination standardization using EPPR-53-04 through EPPR-59-03, and deterioration factors in GTR 23 using EPPR-56-04 and EPPR-65-05. Next meetings are scheduled for 7 September 2026 and October 2026 in conjunction with 95/GRPE.

EV Guard Oy manufactures battery guards for hybrid and electric vehicles using 3 mm marine aluminum and 8 mm recycled PET composite to protect battery packs, liquid-cooling systems, and electrical connectors. The guards distribute impact force, reduce temperature fluctuations, improve energy efficiency, and are 100% recyclable. The company supplies guards to authorized repair shops. No valid regulation currently applies to aftermarket battery shields; UN R100 does not cover this product, representing a structural gap in regulation.

Draft Minutes of the 56th Particle Measurement Programme session held online on 9th July 2026, 12:00-14:30 CET. The meeting reviewed amendments to Brakes GTR 24 and UN R179 across five task forces. TF3a presented layout and testing topics with concerns raised regarding repetition increases and force distribution. TF3b discussed vehicles with limited speed and family classification issues. TF3c addressed brake replacement parts and emission limits. TF4 reported on electromechanical brakes with work package B agreed. TF5 presented the GTR on heavy-duty brake particle emissions with results expressed in mg/km, with some points remaining in brackets pending inter-laboratory comparisons. Comments are due by 16th July, with the next meeting expected mid/end of September 2026 and a hybrid PMP meeting planned for 12th or 13th October in Geneva.

TF 3c addressed brake emission of replacement parts. Proposed amendments include clarification that surface heat-treated discs fall under “other” category, refinement of “Brake Emissions Family Parent” definition, and addition of new appendix to UN Regulation No. 179 Annex 2. Data sharing agreement established: front-to-rear axle emission ratio, brake force distribution, and vehicle electrification type will be shared with aftermarket operators. Two approaches for aftermarket applicants: use vehicle-specific data through benchmarking or bilateral agreements, or apply default values from Tables 5.4 and 5.5. Testing revealed up to 30% variation within friction-couple families. Safety factor application when using actual c-factor values remains under discussion, with final decision expected before October.

Proposal to amend UN R179 following GRPE-94-15e:

• Include supplements on automated vehicle definitions and OICA proposals on family members with higher wheel load but lower wheel load times c-factor ratio,
• Clarify wheel load and vehicle mass definitions for different tests,
• Add wheel load distribution for light commercial vehicles with fully laden mass between 3.5 and 5 tonnes,
• Redefine brake assembly to allow brake calliper reuse if in technically suitable condition,
• Optionally omit cooling air adjustment if temperature requirements are fulfilled,
• Require three emission measurement sections instead of one for type approval with arithmetical average reported,
• Clarify energy calculation for vehicles with limited speed,
• Harmonize reporting requirements including units and decimals,
• Define normalized flows,
• Include transitional provisions stating that vehicle types with existing valid type approvals issued before entry into force of supplement 2 need not undergo new type approval testing.

Task Force 4 has completed revisions to GTR 24 concerning electro-mechanical calipers and proposes to include them in Amendment 3.

Task Force 3b addresses vehicles with limited speed by introducing a new Appendix 3 in Annex 4 to calculate adjusted cycles when vehicle maximum speed is lower than the WLTC-Brake cycle. The proposal modifies brake corner emissions family testing to allow vehicles with limited speed to be included in families with standard vehicles, with emission factors calculated from parent family factors or measured on adjusted cycles. Amendments address c-factor measurement, cycle-adjusted brake events, kinetic energy dissipation tolerances, and report file specifications.

Proposal to insert new paras. 3.3.29. to 3.3.33. defining “Semi-Metallic-Organic,” “Low-Steel-Organic,” “Non-Asbestos-Organic,” and “Low-Steel-Non-Organic” friction materials and “Pad area,” amend Annex 2 title to read “Annex 2 Communication,” insert a new footnote to Annex 2, and insert a new Annex 2 – Appendix containing a list of vehicle data for UN Regulation No. [XXX] approvals including vehicle type description, brake linings and discs specifications, vehicle test mass, maximum speed, tyre dimensions, brake circuit configuration, and brake specifications.

This document proposes a new UN Regulation on uniform provisions concerning approval of non-original and identical replacement brake parts regarding particulate emissions. The regulation applies to laboratory measurement of brake emissions from non-original replacement brake pads, linings, discs, and drums for vehicles of categories M₁, N₁, and N₂ originating from vehicles with type approval under Regulation No. 179. Approval requires emission factors to comply with specified limits based on vehicle category and powertrain technology. The regulation establishes brake emissions families based on characteristics including calliper type, vehicle axle location, friction material formulation, brake disc or drum material, disc surface form, friction material surface area, and drum diameter. Testing procedures, conformity of production requirements, marking and packaging specifications, and approval extension procedures are detailed.
