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 IWVTA IWG submitted an Informal Document regarding amendments to the General Guidelines on Transitional Provisions to introduce a new paragraph P in Annex 1 for the current V9&V9bis, Section II, and to add a headline to paragraph V and paragraph V.+1 in the same section. The IWVTA IWG submitted an Informal proposal regarding amendments to UN R0/09 series as an annual update on UN Regulations applicable to IWVTA. A joint workshop with the DETA IWG was held on 17 June 2026 in Flensburg, Germany with approximately 80 participants from authorities, technical services, and industry. Key outcomes include considering organizing a second workshop in Asia, conducting a survey on desirable DETA and IWVTA systems, and developing supporting materials explaining manufacturer application procedures.

Proposal to amend General Guidelines for United Nations regulatory procedures and transitional provisions in UN Regulations based on WP.29/2024/76, adding permanent transitional provisions applicable to all series of amendments allowing Contracting Parties to grant type approvals according to any preceding series of amendments and continue granting extensions of existing approvals, reorganizing series-specific transitional provisions with provisions for the XX Series and subsequent series, and deleting former para. V.9 and V.9bis provisions that shall be repositioned as permanent provisions.

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.

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.

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.

Proposal to amend para. 3.3., Group 5 to add LED replacement light source categories H9, H10, HB3, and HIR2, insert new sheets H9_LEDr/1 to 7, H10_LEDr/1 to 7, HB3_LEDr/1 to 7, and HIR2_LEDr/1 to 7 in Annex 3, and update the Status table to reflect Amendment 13 based on TFSR-28 documents, with H10 proposal based on GRE-94-19, specifications derived from enforced LEDr category sheets and equivalence criteria detailed in GRE-83-15.

The GRE Task Force on LED Substitutes / Retrofits prepared proposals for four new LED replacement light source categories: H9_LEDr, H10_LEDr, HIR2_LEDr, and HB3_LEDr, developed in accordance with GRE-91-14 and GRE-94-18 and taking into account equivalence criteria detailed in GRE-83-15. All four categories meet photometric, thermal, and electrical performance requirements using established bi-directional equivalence concepts. H9_LEDr, HIR2_LEDr, and HB3_LEDr employ control point requirements instead of black-top specifications. All four categories have longer area B with modified homogeneity requirements. H9_LEDr contains a single luminous flux specification of 1875 lm at 13.2V to limit impact on beam performance in high-beam and bi-functional applications.

Documents TFSR-29-02 and TFSR-29-03 were agreed for submission to GRE95 as formal and informal documents respectively. The group discussed enforcement and market surveillance issues, including concerns about non-compliant products lacking proper cap keying and approval marking visibility when installed. A status report detailing these non-compliance cases will be prepared for GRE95 consideration.

This intermediate draft proposes a new UN Regulation on ADS Marker Lamps based on discussions in technical groups. The regulation establishes requirements for approval of ADS Marker Lamps for motor vehicles of categories M₁–M₃, N₁–N₃, L₆–L₇, and O, as well as vehicle installation requirements. Key provisions include definitions of front, rear, and side ADS Marker Lamp categories with specifications for luminous intensity, colour (blue-green), geometric visibility angles, and positioning. The regulation covers lamp approval procedures, technical requirements, conformity testing, markings, and vehicle-level installation specifications including electrical connections, operational conditions, and interactions with direction indicators. Transitional provisions and communication forms for approvals are included.

The task force reviewed draft technical requirements for ADS-ML (ADS marker lamps) as presented in AVSR-31-02 and discussed a hybrid regulation draft in AVSR-31-03. Key discussions addressed substitution of conventional functions, visibility requirements, installation specifications for vehicles of category M₁ and N₁, and deletion of response time requirements. Trailers were deleted from the scope. The taskforce agreed to further work on the hybrid regulation with a 32nd intermediate meeting scheduled for 7 July 2026 and a 33rd meeting in Tokyo in September 2026.

The agenda includes discussion of ADS marker lamps with a draft proposal for a hybrid regulation, miscellaneous matters, and next steps including a working plan for future activities. The next meeting is scheduled for 7 September 2026, 13:00–17:00 JST in Tokyo as a hybrid meeting.

Discussion focused on ADS marker lamps including scope regarding agricultural vehicles, incorporation with direction indicators, and intensity reduction possibilities, with feedback from France and Japan requested on critical topics documented in AVSR-32-02. Input from GTB on Part I is expected by mid-July, with a cleaned-up proposal to be sent to GRE-95 in October following the 33rd meeting on 7 September 2026 in Tokyo (hybrid format per SLR-78-01/Rev.2).

Proposal to address open questions for a hybrid regulation for ADS marker lamps:

• Whether agricultural vehicles (category T) should be included in the scope,
• Whether a reference to UN-R86 is needed,
• Which use cases should be considered for ADS ML, including validity for parking conditions,
• Which functions required by UN-R48 could be substituted by an ADS ML,
• What interested contracting parties think about the proposed provisions for ADS ML totally or partially reciprocally incorporated with other functions.
