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.

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.

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.

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.

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 insert new paragraphs 0 through 0.1.2, amend paragraphs 1.1, 1.3, and 2.12, insert new paragraphs 2.9.4 and 2.32, delete paragraphs 2.26 and 2.27, insert new paragraph 3.1.9, insert new paragraph 6.11 with sub-paragraphs, amend paragraph 9.3.2, and amend Figures 3, 4, 5, and 6 in Appendix 8, and add items 74 and 75 to Annex 2A, insert paragraph 7 in Annex 3A, and amend Annex 4, Annex 5, Annex 6, and related sections to accommodate ADS vehicles, including categories X and Y.

Proposal to introduce Automated Driving System (ADS) requirements into the Regulation and correct figures in Appendix 8. The proposal inserts new introductory paragraphs addressing vehicles of categories X and Y equipped with an ADS; amends paragraph 1.3 to include ADS control requirements; inserts new paragraph 2.9.4 on ADS presence; extensively revises paragraph 2.12 on immunity related functions to include ADS-related functions; deletes paragraphs 2.26 and 2.27; inserts new paragraph 2.32 defining “ADS test configuration”

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 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 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 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.

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.

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.

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.
