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 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.

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.

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 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.

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 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 agenda and minutes from the 51st session were adopted without comment. The group discussed a status report on Supplement 3 to UN R10.07, updated Terms of Reference, and proposals for the 08 series of amendments, with decision to move submission to 2027/2028 to integrate test modes for automated driving systems. The group reviewed proposals on steer-by-wire systems, CISPR average detector clarification, flicker requirements, and AC/DC charger specifications, concluding that most require further elaboration or revision. The 53rd meeting is scheduled for 1–2 July 2026 in Paris.

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.

OICA proposes that Roadmap Items 2, 2bis, 3, and 4 be withdrawn or deferred until relevant international standardization bodies publish validated methodologies. OICA opposes radiated emissions requirements below 30 MHz in driving and charging modes, radiated emissions in the 16 GHz range, and variable driving conditions assessments, citing lack of technical rationale, absence of published international standards, poor reproducibility for large vehicle categories M₃ and N₃, and inconsistency with WP.29/2024/39 reproducibility standards. New R10.08 work items must demonstrably enhance safety, align with published international standards, and maintain regulatory stability per ECE/TRANS/WP.29/1044/Rev.3 and WP.29-196-07, WP.29-196-26, and ECE/TRANS/WP.29/1182.

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.

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.

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.

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.

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.

OICA opposes inclusion of four roadmap items in UN R10.08 amendments based on WP.29 principles for evidence-based rulemaking. Items 2 and 2bis (radiated emissions below 30 MHz) fail reproducibility standards, lack validated test methods for all vehicle categories, and rely on standards not applicable to internal combustion engine vehicles. Item 3 (16 GHz range) violates the requirement for specific standard versions as CISPR 12 lacks finalized methodology. Item 4 (variable driving conditions and 4-side antenna assessment) presents measurement reproducibility concerns. OICA recommends deferral pending publication of validated international standards.

Proposal to update Terms of Reference for the Informal Working Group on Electromagnetic Compatibility. Items 21 and 22 add timelines for the 08 series of amendments of UN Regulation No. 10: an informal document for the 95th session of GRE in October 2026, and a formal document for the 96th session in April 2027, with final submission by end of January 2027, for adoption in WP.29 in November 2028.

The IWG-EMC 51st session (March 2026) addressed the roadmap for UN R10.08 amendments and proposals. Key discussion items included transitional provisions for UN R10.07, artificial network corrections for Supplement 3, harmonics and flicker requirements, radiated emissions aligned with CISPR standards, and extensive work on automated driving system (ADS) fitness requirements. The group extensively debated ADS test configurations, immunity and emissions testing, laboratory capabilities, and steering system requirements. Multiple proposals—including IWG-EMC-51-04, IWG-EMC-51-06, and IWG-EMC-51-07 on harmonics and flicker—were discussed. The session concluded with plans to submit ADS fitness proposals and artificial network corrections as Supplement 3 of UN R10.07 to GRE, with next meetings scheduled for May and July.

IWG EMC prepared supplement 3 to the 07 series of amendments to UN R10, with terminological adjustments for ADS adoption, addition of categories X and Y, technical refinement of ADS including a new ADS table in Annex 6 paragraph 2.1.1.2, and modifications to artificial networks with discharge voltage below 50 V and maximum discharge time of 20 seconds. For the 08 series, approved proposals are prioritised on a roadmap.

Proposal to amend to fit Automated Driving System (ADS) requirements. New provisions introduce vehicles of categories X and Y equipped with an ADS, extending application to vehicles without driver’s compartment and manual driving controls.

Proposal to amend UN Regulation No. 10 (Electromagnetic Compatibility) through a Supplement to the 07 series of amendments to fit Automated Driving System requirements. The proposal introduces new paragraphs defining ADS and ADS test configuration; amends paragraph 1.3 to include ADS control; expands paragraph 2.12 on immunity-related functions to cover ADS sensor performance; deletes paragraphs 2.26 and 2.27; adds paragraph 6.11.3 on special ADS requirements; and introduces an “Active ADS Mode” test table in Annex 6 paragraph 2.1.1.2, establishing test conditions for vehicles with active ADS features performing the Dynamic Driving Task.

The document discusses transitional provisions for UN R10.07 series amendments, which entered into force June 2025. Contracting Parties shall not refuse type approvals under the 07 series amendments. As from 1 September 2029, Contracting Parties need not accept type approvals under preceding series first issued after that date, but shall continue accepting those first issued before that date for vehicles, vehicle systems, equipment, and parts not affected by changes introduced by the 07 series amendments. The document references ECE/TRANS/WP.29/1044 rev3 for general transitional provision guidance. Nearly all vehicles and ESAs will not be granted extensions for UN R10.06 after 1 September 2029, except those complying only with broadband emissions.

Proposal to insert new paragraph 5.3. into UN R178 (Emergency Lane Keeping Systems). The new paragraph requires that the effectiveness of ELKS shall not be adversely affected by magnetic or electrical fields, demonstrated by fulfilling technical requirements and respecting transitional provisions of the 06 or any subsequent series of amendments to UN R10. This proposal aims to ensure Electromagnetic Compatibility and make the reference future proof for potential ELKS requirements in future series of amendments to UN R10, based on GRVA-24-05/Rev.2.

Proposal to amend UN R10 by inserting new paragraphs to address Automated Driving System (ADS) requirements. The supplement to the 07 series of amendments extends the Regulation’s application to vehicles of categories X and Y equipped with an ADS, as well as conventional vehicles with an ADS, while maintaining the spirit of the original Regulation. Modifications include new definitions for “ADS test configuration,” revised immunity related functions to account for ADS sensor performance, and updated test conditions specifying that ADS shall be operational during testing. Alternative testing methods may be used when the ADS cannot function in the laboratory environment, subject to type-approval authority agreement.

Proposal from the GRE EMC informal working group. The modifications extend the regulation’s scope to vehicles without driver compartments or manual controls. Changes include new definitions for ADS test configurations, updated immunity-related functions to address ADS sensor performance, and revised test conditions for vehicles with active ADS features. Additional reporting requirements for ADS systems are introduced in regulatory forms.

The proposal revises UN R10 paragraphs 3.1.8, 6.10.7 to clarify that intentional emissions from approved RF transmitters are excluded from emission limits when installed per manufacturer instructions without modification. New paragraph 3.1.9 requires risk assessment documentation for radio equipment installations.

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.

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.
