The IWG-EMC 52nd meeting is scheduled for 7 May 2026 as a web conference. The agenda includes feedback from the GRE 94th session regarding Supplement 3 to UN R10.07 and discussion of the roadmap for 08 series of amendments with proposals from Contracting Parties and non-governmental organizations. The session will address GRE-94-56-Rev.2 and documents covering topics such as harmonics limits, charging conditions, immunity requirements, and radiated requirements. The next meeting is scheduled for 1–2 July 2026 in Paris.

Proposal to add radiated emission testing requirements in the frequency range 1 GHz to 6 GHz. New clause 6.2.2.5 specifies limits for vehicle measurements at 3.0 ± 0.05 m antenna distance using peak and average detectors, with limits of 70/50 dB(V/m) for 1000–3000 MHz and 74/54 dB(V/m) for 3000–6000 MHz. New Annex XY describes test methods using IEC 61000-6-3 Ed.4.0 and CISPR 12 provisions. New clause 6.5.3 establishes ESA broadband type approval limits with higher thresholds. New Annex XZ prescribes ESA measurement methods, including test arrangements for REESS charging mode coupled to the power grid.

Proposal to establish items for the 08 series of UN R10: address immunity-related functions required by multiple UN Regulations through discussion of whether to include these features in UN R10 or relocate electromagnetic compatibility provisions to individual UN Regulations; amend test procedures for complex systems including steer-by-wire, brake-by-wire, and ADAS features to establish clear protocols and reduce unlevel playing field items; improve the general approval process through precise vehicle type description and definition of high-level objectives; describe dwell time selection through ISO standard 1154 as minimum; discuss ISO 17025 evaluation principles; discuss antenna position at 3m versus 10m for best-case and worst-case scenarios; and require robust electromagnetic compatibility protection with critical details described in test reports and information documents.

LED replacement light sources without type approval are being sold online and offline and are unsafe for public roads; vehicles equipped with such products would fail PTI. LED replacement light sources with type approval are available either at national level or according to UN R37, and are safe and legal for public roads; vehicles equipped with approved LED replacement light sources shall NOT fail PTI. Approval marking on installed light sources is not accessible during PTI; verification may involve a sticker on headlamp housing, type approval documents, or packaging, with removal of the light source as a last resort to verify the approval marking.

Proposal to insert new paras. 12.15. and 12.16. to establish transitional provisions, and amend Annex 4, Part A, Section I to update the list of requirements for U-IWVTA. Para. 12.15. provides that as from the official date of entry into force of the 09 series of amendments, no Contracting Party applying this UN Regulation shall refuse to grant or refuse to accept an IWVTA issued pursuant to this UN Regulation as amended by the 09 series of amendments. Para. 12.16. provides that as from 1 September 2027, Contracting Parties applying this UN Regulation shall not be obliged to accept type approvals to any of the preceding series of amendments, first issued after 1 September 2027. The amendment updates the table in Annex 4 to specify series of amendments for various UN Regulations including amendments to UN R14, UN R16, UN R46, UN R48, UN R79, UN R94, UN R95, UN R100, UN R110, UN R127, UN R129, UN R134, UN R137, UN R138, and UN R154.

Proposal to address REESS using offboard AC/DC chargers. Some vehicles with REESS use offboard AC/DC chargers, a configuration not described in UN R10. The proposal adds test configurations for vehicles charging through offboard AC/DC chargers to multiple annexes, including flowcharts defining charging mode configurations and specifications for AMN or DC-charging-AN or AN for offboard AC/DC chargers below 60 Vdc. The proposal is based on IWG-EMC-49-12e.

Revision of TFSR-26-03 addresses H9 LEDr flux considerations and dual-voltage specification. The document proposes applying a single specification for H9 LEDr: 1875 lm ±10% @13.2V, representing a compromise between high-beam and low-beam applications. This luminous flux level is not critical, as high-beam measurements with H9 filament bulbs exceed legal minimums by more than 10%, and low-beam safety margins remain acceptable with limited flux increases. Additionally, a black-top limit of 50 cd/klm at control point zero is proposed for bulbs without black-top specification, and LEA sub-zone specifications (B1, B2, B3) for high-beam categories should be optimized to support beam performance.

This document defines essential dimensions, electrical characteristics, and photometrical requirements for LED light source category H9. The LED light source shall not exceed the specified envelope and shall function in either voltage polarity.

The 1st DETA/IWVTA Joint Workshop is scheduled for June 17, 2026, 9:30–12:30 (CEST) as a hybrid meeting in Flensburg. The provisional agenda includes opening remarks from the DETA Chair, IWVTA Chair, and President of KBA. Part 1 covers DETA topics: what DETA is, a demonstration, ASEAN countries’ expectations, and ways to make DETA more attractive. Part 2 covers IWVTA topics: what IWVTA is, industry’s expectations, issuance and acceptance of IWVTA certificates in the EU, and ways to make IWVTA more attractive. The workshop concludes with any other business.

IWVTA is an internationally recognised whole vehicle type approval scheme within the revised 1958 Agreement framework. It establishes mutual recognition of vehicle type approvals at the whole vehicle level across Contracting Parties, eliminating requirements for further testing, documentation, or certification for safety, environment, energy, and anti-theft. IWVTA comprises two approaches: U-IWVTA applies the highest stringency of latest UN Regulations, while L-IWVTA permits omissions or lower stringency versions. The scope is limited to passenger cars. Merits include simplified type approval systems, reduced testing and administrative costs, and shortened processing times.

The document is an agenda for the 31st meeting of the GRE Taskforce on Autonomous Vehicle Signalling Requirements, scheduled for 18 June 2026 from 09:00 to 13:00 CEST via WebEx. The agenda includes welcome remarks, introduction of participants, adoption of the agenda (AVSR-31-01), approval of the report of the 29th meeting (AVSR-30-05), a report from GRE-94 / TF FADS (GRE-94-23), discussion of ADS marker lamps including Japanese input and a draft hybrid regulation proposal (AVSR-28-02, AVSR-30-03, AVSR-31-02/-03), miscellaneous items, working plan for future steps, and next meeting arrangements. Japan has offered to host a September meeting in Tokyo.

Draft technical specifications establish mandatory ADS marker lamps on motor vehicles of categories M₁–M₃, N₁–N₃, L₆, and L₇, with front and rear lamps mandatory and side lamps mandatory or optional depending on vehicle length. Front lamps require daytime photometry of 50–300 cd and nighttime 10–125 cd; rear lamps require 20–120 cd daytime and 4–42 cd nighttime. Side lamps vary by type. All lamps are blue-green turquoise, mounted at minimum 250 mm height, and activate automatically only in fully automated mode with manual switching prohibited.

The European Commission presents prioritized proposals toward updating UN R10 to address transformative vehicle technologies including electrification, automated systems, steer-by-wire, V2X communication, and software-defined vehicles. Current interpretation does not guarantee safety and environmental protection under real road conditions. Proposals include assessing radiated emissions from four vehicle sides rather than two, testing under normal driving conditions, and establishing agreement on drive cycles and transients. These proposals align with WP.29 guidance, improve safety, ensure reproducibility, and represent adaptation to technological progress, based on follow-up of EMC-46-04 and EMC-49-09.

OICA proposes amendments to LUPC-09-04: amend para. 2.5.22. to expand the definition of energy status indicator to include information on the operational status of energy transfer and illumination to assist in locating electrical connection; delete existing para. 3.2.10. and its subparagraphs; add new paras. 3.2.10. and 3.2.11. requiring statements on energy status indicator lamps and lamp test mode; and amend para. 6.29.9. to clarify that multiple energy status indicators may be installed, change the flashing frequency limit from 2.0 Hz to 5.0 Hz, and enlarge the maximum apparent surface area to accommodate various plug sizes and surrounding illumination designs.

This document presents the draft agenda for the 8th meeting of the GRE Task Force on Glare Prevention, scheduled for 9 June 2026 at CLEPA Headquarters in Brussels. The agenda includes welcome remarks, adoption of the agenda, approval of the previous meeting report, feedback from GRE-94, and status updates on HWT on PTI, ADB/AFS, and Regulation 48. Discussion topics cover horizontal adjustment of passing- and driving-beam and AFS-ADB, vehicle preparation for passing-beam measurement, and updates from the GTB Task Force Glare Control. Future meetings are scheduled for Tokyo in September 2026 and Brussels in December 2026.

OICA opposes introducing a regulatory requirement for horizontal adjustment of passing-beam/driving-beam and for AFS/ADB to the current SLR agenda. The proposal does not contribute to simplification of lighting regulations, no identified safety concern or ambiguity justifies this requirement, and it lacks a formal proposal from a Contracting Party, NGO, or other stakeholder. The SLR group is managing several longstanding unresolved issues, and introducing this topic risks further delaying progress. Harmonized requirements require comprehensive understanding of Periodic Technical Inspection specifications across all Contracting Parties, which are currently unavailable.

Annex 6 specifies methods for measuring variations in motor vehicle passing-beam inclination caused by changes in vehicle attitude due to loading. Para. 4 establishes vehicle preparation requirements: vehicles shall have travelled between 1,000 km and 10,000 km; tyres shall be inflated to full-load pressure with full fuel replenishment; parking brake released and gearbox in neutral; conditioning for at least 8 h at specified temperature; and headlamps with well-defined passing-beam cutoff should preferably be installed. Comments on para. 4 question compatibility with periodic technical inspection (PTI) requirements.

The agenda includes review of Terms of Reference and Rules of Procedure, a recap of the GRE 94th session, discussion of questionnaires, a proposal for modification of UN R48, follow-up on action items, review of existing Regulations and Standards, and announcement of the next meeting.
