Flicker measurement: a) reduction of observation time and suppressing Plt limit, b) adapting ESA limit specification aligning with the vehicle requirement, c) suppression of manual switching test, d) Improving measurement consistency between laboratories and clarify test conditions.

Proposal to improve measurement consistency between laboratories and clarify setup conditions.

The IWG-EMC 50th session reviewed proposals for the UN R10.08 series of amendments on electromagnetic compatibility for vehicles. Key topics included charging system requirements, harmonics limits, radiated emissions, and checking UN R10 for applicability for ADS vehicles. Multiple proposals from Contracting Parties and stakeholders were assessed regarding inclusion in the 08 series, with deadlines set for working documents by July 2026. The roadmap for implementation was reviewed, with items categorized for immediate inclusion, future series consideration, or further development. A revised ADS update for UN R10 was discussed. Copyright issues with ISO, CISPR, and IEC standards were addressed. Next sessions scheduled for January, March, May, and July 2026.

The meeting reviewed proposals for LED retrofit (LEDr) categories including H10 front fog lights and H9 high beam types for Regulation 37/RE.5. Key discussions addressed H10 failure requirements, H9 dual-voltage flux levels, and homogeneity requirements for B-type boxes. The task force also focused on market surveillance and enforcement mechanisms to ensure only approved LEDr products are used on public roads. The next meeting is scheduled for 20 April 2026.

Proposal to amend UN R10 to enable application to Automated Driving System (ADS) vehicles, including new paragraphs defining ADS requirements, test configurations, and immunity-related functions. Changes address vehicles without drivers or manual controls, establish ADS test procedures for laboratory environments, and specify equipment operation during testing. Amendments cover electromagnetic compatibility testing requirements, failure criteria, and documentation standards for ADS-equipped vehicles.
