Task force in-session amendments to the proposal to establish uniform provisions for approval of vehicles of category N₁Y regarding protection of fuel system integrity, protection against electrical shock, and vehicle crash compatibility. Requirements address liquid fuel leakage limits, compressed hydrogen storage system integrity including leakage rates and container retention, high voltage electrical system protection through absence of high voltage, low electrical energy, physical protection, or isolation resistance, electrolyte leakage limits for rechargeable energy storage systems, REESS retention, fire and explosion hazards, and crash compatibility criteria. Testing includes frontal collision per UN R94 or UN R137, lateral collision per UN R95, and rear-end collision per UN R153. Vehicles derived from approved N₁ types complying with specified series may demonstrate compliance through previous test results.

Proposal to establish a new UN Regulation for approval of vehicles of category N₁Y regarding fuel system integrity, electrical shock protection, and crash compatibility. The regulation specifies requirements for frontal, rear-end, and lateral collision tests based on existing UN Regulations (No. 94, 95, 137, and 153), with provisions for liquid fuel leakage limits, hydrogen fuel system integrity including shut-off valve closure and leakage rate limits, electrical protection from high voltage systems, REESS retention and fire hazard prevention, and crash compatibility criteria and values determined from longitudinal acceleration measurements.

Proposal to establish uniform provisions for type approval of vehicles of category N₁Y regarding fuel system integrity, electrical shock protection, and crash compatibility in frontal, lateral, and rear-end collisions. Requirements cover fuel leakage limits, hydrogen storage system integrity post-crash, high voltage electrical safety, REESS protection, and crash compatibility criteria. Tests reference UN R94, UN R95, UN R137, and UN R153. Vehicles derived from already-approved types may use previous test results if mass increase does not exceed 8 per cent. Approval marks and type approval procedures follow standard 1958 Agreement schedules.

Proposal to amend UN Regulations Nos. 11, 12, 14, 16, 17, 21, 94, 95, 100, 127, 134, 135, 137, 153, 173, 174 and 184 to incorporate provisions related to RXSWIN in accordance with revision 8 of the Consolidated Resolution on the Construction of Vehicles (R.E.3). The amendments insert provisions regarding Software Identification Number definitions, manufacturer information requirements for approval tests, vehicle approval applications for software version differentiation, production discontinuation rules for software updates, and additional information on software identification and updates. Amendments are to enter into force in early 2028.

Work in progress clean draft proposal to establish a new UN Regulation on crashworthiness of vehicles of category N₁Y with regard to protection of fuel system integrity, protection against electrical shock and vehicle crash compatibility in the event of frontal, rear-end and lateral collision. The regulation applies to vehicles of category N₁Y and specifies test procedures for frontal, lateral and rear-end collisions based on UN R94, UN R95, UN R137 and UN R153. Requirements include fuel system integrity with no more than slight leakage or continuous leakage not exceeding 30 g/min, hydrogen leakage rate not exceeding 118 NL per minute, protection against electrical shock through absence of high voltage, low electrical energy, physical protection or isolation resistance, electrolyte leakage limits, REESS retention and fire hazard prevention, and crash compatibility criteria with Crash Compatibility Criterion not exceeding 40–45 g and Crash Compatibility Value not exceeding 100–120 gt.

Proposal to amend para. 3.3.2. to restructure information requirements for rechargeable energy storage systems and insert new paras. 4. to 9.1. to add information requirements for fuel cells, fuses and circuit breakers, power wiring harnesses, protection against electric shock, additional data on power circuit components, and hydrogen systems or components.

Proposal to amend para. 3.3.2. to insert structured subsections for REESS trade name, cell types, physical dimensions, description, electrical specifications, gas combination rate, installation description, thermal management and electronic control, insert new paras. 4. to 9.1. requiring information on fuel cell specifications, fuses and circuit breakers, power wiring harness, protection against electric shock, power circuit component details, and hydrogen system components located in the energy absorption zone. These modifications address insufficiently defined topics on REESS type, electrical system and hydrogen system in vehicles by introducing relevant sections from UN R100 and adding hydrogen system documentation requirements.

Proposal to enable application to vehicles of category X. In the absence of a driver or manual driving controls, provisions related to them shall not be taken into account if not already covered by this amendment. Vehicles of category Y are not in the scope of this Regulation. In manual driving mode, no special provisions or exemptions apply to vehicles equipped with an Automated Driving System other than vehicles of category X.
