Proposal to add editorial corrections to UN R48 series 06 to 09 based on GRE/2024/21/Rev.1 and WP.29/2025/114. Changes include inserting definitions for direction indicator projector, basic element, and direction indicator projection; adding requirements for direction indicator projections

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.

UN R53 series ⁰⁵ baseline amendments simplify the definition in paragraph 2 by deleting common definitions to UN R48, reducing from 49 original definitions to 27. Amendments align failure provision and EV inclusion with UN R48. The communication sheet is amended to align with UN R48. Terminology and format alignment with UN R48 and UN R74 is applied. Previous technical prescriptions are moved to a reference document, keeping only the latest. Paragraphs 6.×.4 and 6.×.5 are simplified, aligning with UN R48. An open point questions whether Annex 1 Communication form should refer to a specific Series of Amendments to R48 definitions.

This amendment modifies definitions in paragraph 2, consolidates general specifications in paragraphs 5 and 6, simplifies failure provisions, includes electric vehicles, aligns terminology with UN R48 baseline and standardizes vehicle category references to “vehicles of category(ies),” corrects AFS provision references, applies scientific notation with lumens, aligns approval number text with UN R48, corrects signal lamp category numbering, uses category symbols instead

Proposal to amend UN R74 series 04 by simplifying the definition in paragraph 2 through deletion of common definitions to UN R48, applying amendments for failure provision and EV inclusion, aligning terminology and format with UN R48 and UN R53, retaining only the latest transitional provisions, simplifying paragraphs 6.×.4 and 6.×.5, and providing editable pictures.

Proposal to amend the definitions ; add EV inclusion; clarify individual and general provisions, failure provisions, and transitional provisions; correct signal lamp category; use category symbol instead of lamp function name;

UN R86 baseline amendments add agricultural non-road mobile machinery to scope. Definitions are simplified by removing common vehicle definitions and aligning structure with UN R48. Headlamps symmetrical classes are reviewed following CLEPA comment. Side retro-reflector requirements align with EU requirements on location. Direction-indicator lamps alignment with EU scope for tractors remains an open point.

Proposal applies to vehicles of categories T, R, and S and agricultural NRMM regarding lighting and light-signalling device installation. The regulation establishes approval procedures, general specifications for lamp fitting and adjustment, electrical connections, and individual specifications for various lighting functions including driving-beam and passing-beam headlamps, direction-indicator lamps, stop lamps, position lamps, retro-reflectors, and other light-signalling devices. It specifies position requirements (height, width, length), geometric visibility angles, colour requirements, and electrical interconnection rules. Transitional provisions address implementation across different amendment series, with staggered acceptance periods for type-approvals granted under preceding series of amendments.

Proposal to editorially correct approved proposal GRE/2024/21/Rev.1 and WP.29/2025/112. Editorial corrections amend paragraph 1 to include reversing projectors and direction indicator projectors in scope. New paragraph 3.1.2.10 requires drawings showing relative position of direction indicator projector and lamp. Tables 1 and 2 are amended to add reversing projector and direction indicator projector entries.

Proposal to amends requirements for LED light source modules and non-replaceable light sources. Amendments specify headlamp and AFS technical specifications including light source module characteristics, electrical interfaces, and photometric values. Requirements for LED light source modules and non-replaceable light sources address design, manufacture, testing conditions, colour rendering, UV-radiation, and objective luminous flux measurement procedures.

The GRE-IWG SLR is simplifying UN Lighting and Light-signalling Regulations through a two-stage process. Baseline documents for UN Regulations 48, 53, 74, and 86 have been prepared as carriers of technical amendments. Stage 2 work addresses improved visibility of rear direction indicators against stop lamps, apparent surface definitions, and correction of errors in UN Regulation 150.

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.

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 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.
