Proposed modifications to ECE/TRANS/WP.29/GRSP/2025/7

Proposal to introduce provisions on thermal propagation as a result of a single cell thermal runaway.

Proposal to amend para. 9.(a) to clarify expansion of the protection scope of electrical and battery safety, including thermal propagation in cases of V2X, parking, and charging. The modification addresses new vehicle functionalities like V2X, defined in UN GTR No. 22, where traction batteries cover external power and energy demand. Additional requirements must be added, including isolation resistance requirements for coupling systems for charging the REESS, as defined in para. 5.1.1.2.4.4. of UN GTR No. 20.

The document presents an update on the amendment of GTR No. 20 concerning new requirements on thermal propagation. CPs/sponsors agreed to delete para. 265, which was considered redundant in view of paras. 263 and 264. The amendment addresses flammability, toxicity, and corrosiveness of vented gas, with final endorsement by GRSP expected in June 2026 and adoption by WP.29 in November 2026.

Proposal to establish UN Regulation on Category Y vehicle crash safety covering frontal, rear-end, and lateral collision protection. The regulation specifies requirements for fuel system integrity, electrical shock protection, and crash compatibility for vehicles without occupants. Requirements address liquid fuel leakage limits, hydrogen storage system integrity, rechargeable energy storage system protection, and electrical safety post-impact. Testing procedures reference existing UN Regulations 94, 95, 137, and 153. Approval processes, conformity procedures, and technical specifications are detailed, including test methods for frontal, lateral, and rear-end impacts with measurement requirements and alternative procedure provisions.

A new general safety regulation for vehicles of category Y, which are not designed to carry occupants, adds provisions requiring repetition of tests described in Annex 3 and Annex 4 when modifications affect the general form of vehicle structure or increase mass by more than eight per cent. For modifications affecting only interior fittings or mass increases not exceeding eight per cent, a simplified test in accordance with UN R94 in its 05 series of amendments or a partial test shall be carried out. The regulation incorporates requirements from UN R94, UN R95, UN R137, and UN R153, and proposes exempting vehicles with maximum design speed not exceeding 50 and 56 km/h from impact test procedures while requiring compliance with post-impact requirements.

A decision was taken in mid-2025 to start drafting a new regulation for category Y vehicles. TF AVRS agreed to amend UN R127 to include Y-category vehicles. Supplement 5 to the 04 series of amendments proposes: for vehicles of category Y, dimensions based on front structural geometry shall determine exemptions ensuring equivalence to R-point criteria; Bonnet Rear Reference Line is defined for category Y vehicles without a windscreen; Front structure definition includes outer structures and, for category X and Y, automated driving sensors essential for vehicle operation; Normal ride altitude testing shall be at Unladen Vehicle Mass.

Proposal to establish uniform provisions concerning approval of vehicles of category N₁ with regard to protection of fuel system integrity, protection against electrical shock, and vehicle crash compatibility in frontal, rear-end, and lateral collisions. The Regulation applies to vehicles of category N₁. Frontal impact provisions are based on UN R94 and UN R137 depending on vehicle mass. Lateral impact provisions are based on UN R95 without the side pole impact test. Rear-end impact provisions are based on UN R153. Vehicles must comply with fuel leakage limits, hydrogen storage system integrity requirements, and electrical safety standards for rechargeable energy storage systems. Post-crash hydrogen leakage shall not exceed 118 NL per minute, gas concentration shall not exceed 4.0 per cent for hydrogen, and containers shall remain attached at minimum one point. Electric power trains must meet protection against electrical shock, isolation resistance, and fire hazard requirements within 60 minutes post-impact. Conformity of production shall be verified on a statistically controlled random basis.

A new general safety regulation for vehicles of category Y is being drafted to collect relevant safety requirements. Vehicles of category Y with a maximum design speed not exceeding the impact speed specified in applicable frontal impact tests shall be exempted from frontal, lateral, and rear-end impact test procedures but must comply with applicable post-impact requirements concerning fuel leakage, hydrogen leakage, electrical safety, REESS electrolyte leakage, REESS retention, and fire or explosion hazards. The draft incorporates requirements from UN R94, UN R95, UN R137, and UN R153. Open issues include crash compatibility requirements for low-speed vehicles, applicability of partial tests, and defining front and rear structures for Y-category vehicles without occupants.

UN R127 amendment proposals include defining pedestrian protection requirements for category Y vehicles. Scope exemptions for category Y vehicles shall use front structural geometry to determine exemptions, ensuring equivalence to R-point criteria. Definitions require adjustments including Bonnet Rear Reference Line for vehicles without windscreens, Front structure definition to include automated driving sensors, Windscreen test area redefined as Upper structure test area where windscreens are non-existent, and supporting definitions for Side reference line and Cowl monitoring area. Testing shall occur at Unladen Vehicle Mass.

A new UN Regulation is being drafted for N₁vehicles of category Y (vehicles equipped with an automated driving system, not capable of manual driving exceeding 6 km/h, and not designed to carry occupants). The draft incorporates crash safety requirements from UN R94, UN R95, UN R137, and UN R153. Draft version 5 adds provisions for simplified approval procedures for previously approved vehicles, references UN R137 for vehicles between 2,500 and 3,500 kg, and clarifies B pillar references. Open issues include confirming non-applicability of lateral collision partial tests and clarifying which simplified procedures are permitted.

A decision was taken in mid-2025 to start drafting a new regulation collecting relevant safety requirements for Category Y vehicles. UN R127 on pedestrian safety performance could be directly amended to include Y-category vehicles instead of including requirements in a new regulation. TF AVRS agreed to amend UN R127 to include Y-category vehicles. A draft regulation (v4) is available proposing supplement 5 to the 04 series of amendments, including amendment suggestions in scope to determine exemptions for Y-category vehicles based on front structural geometry dimensions rather than R-point criteria.
