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. 2.1. to clarify the definition of appropriate adaptor as a test component specified by the CHSS manufacturer that substitutes for container valve, additional TPRD, and end plug, add a Note explaining container valve and end plug embodiments and supply line connection options, add sentences to paras. 5.1.1., 5.1.2., 5.2., 9.2.1., 9.2.3.2., and Annex 3 para. 2.1. to specify that connections between supply lines for additional TPRDs and appropriate adaptors shall meet requirements and are within the scope of the test, delete “through appropriate adaptors” from Annex 3 para. 5.1., and delete the word “hydraulic” in two instances in para. 9.2.1. to clarify that gas can be used as an option for this test.

Proposal to amend paras. 15.1.1. to 15.1.4. to change the transitional provisions and allow Contracting Parties to issue approvals according to the 05 series of amendments. As from entry into force of the 06 series, no Contracting Party shall refuse approval under the 06 series. As from 18 months after entry into force, no Contracting Party shall grant approvals unless the helmet or visor type meets the 06 series requirements. As from 30 months after entry into force, all Contracting Parties shall prohibit approval marks referring to type approvals granted under the preceding series. As from 36 months after entry into force, Contracting Parties may prohibit the sale of helmets and visors which do not meet the 06 series requirements.

Proposal to establish requirements for in-direct plus or direct sensing systems to detect children left unattended in M1 and N1 vehicles under 3,500 kg. Systems shall detect Child Occupants Left Inside (CLIV) events for rear seating positions accommodating child restraint systems and issue audible or audible and visual warnings at least 60 dB(A) within 15–30 seconds of locking all doors, lasting at least 10 seconds and repeating every 90 seconds for at least 20 minutes unless cancelled. The default system setting shall be ON, with deactivation available temporarily for single journeys or long-term for maximum 30 days. Testing shall use CLIV surrogates aged 0, 3, and 6 years per ISO 26315, covering multiple test scenarios including warning delay, cancellation, and temporary deactivation.

The CLIV IWG 20th session reviewed its draft proposal for a bus and coach UN Regulation submitted to GRSP in December 2026, retaining operational isolation terminology with editorial corrections, defining scope as M2 and M3 class B and III vehicles designed for carrying children, and adopting a journey definition covering engine or motor operation until 15 minutes after the vehicle master control switch is turned off. The IWG adopted a 1.5 ± 0.5 Hz repetition rate for warning signals and deferred light-vehicle UN Regulation drafting to a September face-to-face meeting in Paris.

Draft minutes of the 6th meeting of the EqOP Task Force 4 on 7 September 2026 with 33 participants. A technical expert from TUG presented findings on abdominal injuries, showing approximately 9% of injured occupants sustain such injuries, often among the most important alongside thorax, head, and upper extremity injuries, with sex- and age-related differences noted particularly among older female occupants. The group reviewed the progress dashboard, discussed the definition of robustness for the Japan Workshop in November 2026, and deferred the priority table and reading list to the next meeting scheduled for 21 October 2026.

The agenda includes a report from Euro NCAP Workshop on Seat Performance Criteria for EvaRID, and discussion of sub-optimization prevention and the role of dynamic testing.

The regulation applies to vehicles of categories M₂ and M₃, class B and III. Vehicles shall be equipped with a physical inspection system that engages when the vehicle master control switch is turned off and generates an external visual and audible warning if not disarmed within 3 minutes for buses or coaches not exceeding 22 passenger seats, or within 5 minutes for those exceeding 22 passenger seats. The physical inspection system shall not influence the bus or coach’s performance or safe operation, and failure of the system shall not affect safe operation of the vehicle.

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.

Proposal to insert a new paragraph 4.10. requiring any removable insert to have a permanently attached label indicating brand, model and size range with a minimum label size of 40 × 40 mm or equivalent area, and renumber paragraphs 4.10. (former) to 4.12. as paragraphs 4.11. to 4.13. in Supplement 2, and renumber paragraphs 4.11. (former) to 4.13. as paragraphs 4.12. to 4.14. in Supplement 3 to correct paragraph numbering mistakes in section 4.

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.
