The first task force session confirmed the scope of work, organization structure, and timelines for developing UN R40.03 to transpose Euro 4-level requirements from UN GTR No. 2 into UN Regulation No. 40 and to ensure administrative provisions necessary for mutual recognition and type approval. The Task Force agreed to use IMMA proposal EPPR-73-02 as the technical baseline, identified provisions already aligned with GTR No. 2 and those requiring revision, and established a working method for future discussions. TF-02 is proposed for 24 November 2026 and will examine the main text from paragraph 1 through paragraph 12, including Appendix 2.

Status report on the Informal Working Group on Environmental and Propulsion Performance Requirements for L-Category Vehicles. The IWG-EPPR has established a Task Force to transpose UN-GTR No. 2 into the 03 series of amendments to UN Regulation No. 40, co-chaired by Japan and Malaysia with JASIC and IMMA as co-secretaries. The Task Force held its first meeting on 9 October with participation from ASEAN countries, Ghana, and others, and agreed on workplan and rules of procedure. Target dates for deliverables are April 2027 and October 2027.

Field test of on-board diagnostics (OBD) use during periodic emission testing for Euro 5+ motorcycles. Fifty-three Euro 5+ motorcycles were tested to examine feasibility and practicability of OBD-based inspection procedures. All motorcycles had 6-pin or 16-pin connectors. Challenges included locating OBD ports, accessing them with mechanical tools, engine coolant temperature readouts for oil/air-cooled motors, revving to 2500 rpm on some scooters, and measuring lambda with short exhaust systems. OBD information improves periodic technical inspection reliability for Euro 5+ motorcycles.

Draft agenda for the 76th EPPR Informal Working Group Meeting on Environmental and Propulsion Performance Requirements of L-category vehicles, scheduled for 13 October 2026. The agenda covers adoption of the previous meeting’s report, transposition of UN-GTR 2 into UN Regulation 40 with feedback from multiple countries, information exchange on maximum power determination for two-wheelers, battery electric vehicle range determination standardization, deterioration factors in GTR 23, and other business items.
