The agenda includes a roadmap for the 08 series of amendments with proposals from contracting parties and non-governmental organisations, discussion of numerous technical documents covering harmonics, flicker requirements, charging conditions, immunity testing, radiated emissions, and blind spot detection systems. Referenced documents include EMC-52-05, EMC-53-05, EMC-53-10, EMC-53-11/Rev.1 from previous sessions. Subsequent meetings are scheduled online from December 2026 through July 2027, with a face-to-face meeting proposed in November 2027.

Proposal to insert new para. 3.3. requiring that the use of non-durable protection shields (e.g., non-integral ferrite blocks, aluminium foil) shall be prevented, and if used, shall be duly described in the information document and test report.

Proposal to amend Table 2 in Annex 4, paragraph 4.3. to add “Scanning receiver parameters” as heading and add footnote b to minimum dwell time columns stating the selected dwell time shall, in addition, consider the cycle time of certain vehicle functions, e.g. the wiper system, amend Table 2 in Annex 5, paragraph 4.3. to add “Scanning receiver parameters” as heading and add footnote a with identical language, and amend Annex 6, paragraph 4.1. to add language that the selected dwell time shall, in addition, be sufficient for the observer(s) to assess all related vehicle functions, while also considering the cycle time of certain vehicle functions, e.g., the wiper system.

Proposal to insert a new definition of functional test configuration, amend para. 2.1.1.2. to clarify that test conditions are agreed between manufacturer and technical service and that tables provide guidance which may be extended or amended depending on vehicle characteristics, add tables specifying basic vehicle test conditions for “50 km/h mode,” “Brake mode,” and “Active ADS Mode,” add an alternative “Brake mode” with active ADS for vehicles where braking mode cannot be applied with ADS operational without ADS feature(s) activated, add AECS and AVAS test condition tables, and insert a new table cross-referencing UN Regulations with specific provisions and test configurations to demonstrate compliance with UN R10.

Proposal to require test reports provided by manufacturers to comply with paragraph 3.3. and to be attached to the test report of the technical service.

Proposal for conducting the ADS Active Test Specified in Annex 6 to clarify ADS Active Mode, clarify methods to activate ADS using test equipment or by modifying in-vehicle ADS-related ECU software, clarify test objects for ESA at component-level or system-level, and clarify test methods when ADS cannot be activated in an anechoic chamber, including testing in a non-active state using warning indicators and diagnostic functions, and testing when errors occur upon ADS activation. The proposal defines ADS Active Mode as representative ADS functions remaining operational using sensors whose inputs can be simulated within the anechoic chamber environment, with alternative test methods including application based on ESA or subsystem test results, testing with ADS not activated using steady-state driving conditions with pass/fail criteria verifying no communication errors, ECU malfunction, freeze, shutdown, or ADS system malfunctions occur, and testing with simulated sensor outputs using data from real-world driving or representative driving scenarios.

Proposal to amend Annexes 11 and 17 to specify an observation time of 2.5 min for quasi-stationary equipment as defined in Table 4 of IEC 61000-3-2, with the equipment operating in the mode expected to produce the maximum total harmonic current under normal operating conditions. Currently, UN R10.07 does not specify an observation time, which may lead to different interpretations of the test method and case-by-case agreement during type approval. Specifying 2.5 min would provide a consistent observation and averaging period for vehicle and ESA type-approval tests without changing existing test conditions, limits, or evaluation method.

The 53rd session of the Electromagnetic Compatibility IWG was held 1–2 July 2026 in Paris. The agenda addressed proposals for UN R10.08 and related standards, including standardized testing conditions for harmonics and flicker, radiated emission requirements at 1–6 GHz, blind spot detection immunity testing, and steer-by-wire failure criteria. Key decisions included establishing a small drafting group to develop 1–6 GHz requirements if CISPR D produces no usable results by end of 2026, postponing discussion of AC/DC charger proposals, tasking CLEPA and OICA to prepare a joint proposal on harmonics and flicker, and organizing a consolidated version of UN R10.07 with Supplements 1–3 for December 2026. Future sessions are scheduled through September 2027, with a face-to-face meeting proposed for November 2027 in Tokyo. Documents EMC-53-05, EMC-53-08, EMC-53-10, and EMC-53-11/Rev.1 were introduced during the session.

The Netherlands proposes introducing a separate part 2 addressing immunity-related functionality on lateral movement for steer-by-wire and automated driving systems. Harmonics should be tested when issues are observed; in the cited example, step sizes above and below 745–755 MHz and harmonic frequencies at 1500 MHz and 375 MHz require testing. UN R10 should address specific immunity features across multiple UN Regulations, or references should be moved to individual regulations. Test procedures for complex systems like steer-by-wire and brake-by-wire require improvement, including clearer protocols and discussion of specialized technical units. Dwell time must be sufficient to observe all potential fail criteria in agreement between manufacturer and technical service. Antenna switching during testing at 3m versus 10m positions should be forbidden. EMC shielding must be robust and durable, excluding non-integral ferrite blocks and loose components, with critical details recorded in test reports.

Proposal to add para. 6.2.1.3 defining method of measurement in the frequency range 1 GHz to 6 GHz, add para. 6.2.2.5 establishing limits of disturbance with peak detector at vehicle-to-antenna spacings of 3.0 ± 0.05 m and 10.0 ± 0.2 m, add para. 6.3.2.5 establishing limits of disturbance with average detector at vehicle-to-antenna spacings of 3.0 ± 0.05 m and 10.0 ± 0.2 m, rename para. 6.5.2 to specify frequency range 30 MHz to 1000 MHz, add para. 6.5.3 establishing ESA broadband type approval limits in the frequency range 1 GHz to 6 GHz with measurement frequency requirements based on highest internal frequency, add para. 7.3 establishing specifications concerning narrowband electromagnetic radiation from vehicles with method of measurement and type approval limits, rename para. 7.10.2 to specify frequency range 30 MHz to 1000 MHz, add para. 7.10.3 establishing ESA broadband type approval limits in the frequency range 1 GHz to 6 GHz with measurement frequency requirements, add Annex XY defining method of measurement of radiated broadband and narrowband electromagnetic emissions from vehicles in the frequency range 1 GHz to 6 GHz, add Annex XZ defining method of measurement of radiated broadband electromagnetic emissions from electrical/electronic sub-assemblies with test setup figures, and add Appendices z1 and z2 establishing vehicle reference limits at 10 m and 3 m antenna-vehicle separation respectively.

The 7th Edition of IEC CISPR 12 was issued in June 2025, with work commencing on an 8th Edition. Two Special Task Forces are developing updates: one investigating dynamic testing at alternative fixed speeds and acceleration/deceleration modes, and another developing a measurement method for the frequency range 1 GHz to 6 GHz. An 8th Edition CISPR 12 is estimated for issue May–July 2028. For IEC CISPR 36, a Special Task Force concluded that conducted voltage emission measurements are more appropriate than magnetic radiated methods for charging mode testing. A 2nd Edition incorporating conducted voltage charging mode measurements is estimated for issue September–November 2027.

Methods for evaluating electromagnetic immunity of blind-spot detection systems are proposed using a simple reciprocating motion device equipped with a reflector. The electromagnetic immunity test is conducted after the BSD system has been activated. Vehicle’s electromagnetic immunity test methods and conditions are consistent with the previous ones. Reproducibility has been verified across various vehicle models with only minor adjustments required. The proposal seeks opinions from member countries regarding the necessity of electromagnetic immunity evaluation methods for BSD systems.

Proposal regarding methods for evaluating electromagnetic immunity of blind-spot detection systems. The proposal identifies this as a subject for discussion as part of ADAS evaluation methods. The form requests consideration of revisions to evaluation methods, with reference to presentation materials. The proposal’s disposition status remains to be determined by the IWG.

CLEPA proposes standardized testing conditions for harmonics and flicker in UN R10 across countries with differing grid voltages and frequencies. Three cases are presented: Case 1 applies requirements to 220–240 V single-phase or 380–415 V three-phase at 50 or 60 Hz only; Case 2 permits multi-voltage operation but tests only at 220–240 V or 380–415 V; Case 3 applies scaled limits for region-specific operation at different voltages such as 100 V, with IEC 61000-3-3 and IEC 61000-3-11 marked not applicable due to impedance specifications limited to 220–250 V systems.

Proposal to clarify ADS Active Mode and methods to activate ADS using test equipment or by modifying software of in-vehicle ADS-related ECUs, clarify test objects for ESA at component-level or system-level, and clarify test methods when ADS cannot be activated in an anechoic chamber, when testing in a non-active state using warning indicators or diagnostic functions, or when errors occur upon activation of ADS. This is a preliminary proposal intended for presentation at IWG EMC meetings in Autumn 2026.

The EMC informal group proposes to hold a meeting in Tokyo during the 2nd or 4th week of November 2027, with demonstration venue also in Tokyo. Proposed demonstration content is to be determined for automated driving systems. The meeting contents are subject to change.
