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

Proposal to update of ISO standard referred in this Regulation as alternatives

Supporting presentation for proposals to remove para. 6.2. and Annex 9A, remove para. 6.3. and Annex 9B, remove para. 6.5. and Annex 9E including Appendix 1, remove para. 6.10. and Annex 9J, exempt from isolation resistance measurements after each test, allow sequential execution of over-discharge and overcharge tests, remove standard cycle after each test, unify thermal event warning requirement by removing para. 6.14., and allow alternative conditions for ambient temperature for SOC adjustment. The document also proposes guidance on REESS type definition.

Proposal to streamline the Regulation by eliminating redundant requirements and their test procedures as well as to clarify the possible alternative methods to improve the efficiency of the tests: Delete paragraphs 6.2. and 6.3., delete paragraph 6.5., delete paragraph 6.10., reserve paragraphs 9A, 9B, and 9E, delete paragraph 6.14., amend paragraph 6.15. to add comprehensive thermal propagation verification procedures including risk management analysis alternatives, add paragraph 6.16. for REESS and vehicle communication compatibility, add new Part III (para. 7.) for approved REESS installation requirements, renumber existing paragraphs 8.–13. as paragraphs 8.–13. and add corresponding section numbering, amend scope provisions to clarify application to vehicles of categories M, N, and O with specified e-axle battery provisions, add vehicle category O definitions including “e-axle” and “trailer load compartment,” amend various paragraphs to reference vehicles of categories O₃ and O₄, amend protection requirements to include trailer load compartments, amend over-discharge and overcharge test procedures to permit sequential execution, amend isolation resistance measurement requirements to exempt measurement when isolation resistance monitoring systems are installed and confirmed functional, clarify SOC adjustment procedures to permit alternative ambient temperatures when highest SOC is achievable independently, add labelling requirements for vehicles of categories M₂/N₂ and M₃/N₃ in accordance with ISO 17840-4:2018, add provisions for Automated Driving System (ADS) features and warnings, add provisions for vehicles of category Y regarding mechanical integrity validation at component level, amend Annex 1 Part 2 to revise installation restriction references, add Annex 9K describing four thermal propagation trigger methods with four appendices, and add Annex 10 specifying label provisions for electric power train vehicles.

Proposal to provide guidance for interpretation of “Type of REESS” (Rechargeable Electrical Energy Storage System) as defined in UN R100 para. 2.48. The document establishes that differences in REESS should be evaluated from the perspective of substantial impact on safety performance. It describes key elements for assessing impact on safety within each essential aspect: manufacturer responsibility, cell chemistry/capacity/physical dimensions, cell number/connection/support, casing construction/materials/dimensions, and ancillary devices. The guidance provides examples of changes not causing or potentially causing significant differences, including production location changes, multi-sourcing of cells, and process improvements.

Proposal to insert new paragraphs 0.2. and 0.2.1. to clarify the assessment procedure for door opening and permit the use of an external vehicle lift to return a vehicle to its wheels following the side impact test for workshop health and safety compliance, and insert new para. 5.3.3.1.1. to specify that if necessary the vehicle shall be put back on its wheels and paragraphs 5.3.3. and 5.3.3.1. shall apply once in this condition.

Proposal to insert a new paragraph 0.4. explaining that the second level warning of safety-belt reminders is intended to warn if one safety-belt is unfastened during normal driving conditions as specified in paragraph 5.2.4.1., and that other safety warnings may alert the driver to check overall safety of occupants and stop the vehicle, with the second level warning discontinued per paragraphs 5.2.4.3.(a) to (c)©, and amend paragraph 5.2.4.3. to add a new subparagraph (d) allowing discontinuation of the audible signal when other audible safety warnings are triggered in circumstances of imminent danger where the vehicle has to be stopped.

Updated document with in-session comments.

Proposal from the International Organization of Motor Vehicle Manufacturers (OICA) to include requirements for automatic door locking systems. This OICA proposal would allow for ‘mixed configuration’ of both locked and unlocked doors during testing.

Proposal from the International Organization of Motor Vehicle Manufacturers (OICA) to include requirements for automatic door locking systems. This proposal would allow for “mixed configurations” of locked and unlocked doors in the test procedures.

Text from the International Organization of Motor Vehicle Manufacturers (OICA) proposing to introduce exemptions for vehicles not intended for transporting children during normal use.

Text from the International Organization of Motor Vehicle Manufacturers (OICA) proposing to exempt vehicles with one seating position per row from ISOFIX provisions since compliance would require fitment to the driver’s seat.

Text from the International Organization of Motor Vehicle Manufacturers (OICA) proposing provisions for the coupling systems for charging the Rechargeable Energy Storage System (REESS).

Text from the International Organization of Motor Vehicle Manufacturers (OICA) proposing to remove unnecessary constraints to electric vehicle systems having a working voltage of 48 V and to adapt the safety provisions to this technology.

Proposal to further clarify the risk of installing a rearward-facing child restraint in a seating position that is equipped with a frontal airbag. The text is based on a document GRSP-52-06 as discussed during the 52nd GRSP session (document GRSP-52, para. 23).

Draft text that would adapt the GTR on hydrogen vehicle safety to the type-approval system via a new UN Regulation.

UN R17, R25 and R80 address head restraints for various categories of vehicles. In order to prevent redundant application of these regulations, this amendment clarifies that head restraints approved under UN R17 would be exempted from the requirements of UN R25 and that UN R25 does not apply to coach and bus seats approved under UN R80.

Draft text for the transposition of GTR No. 13 on hydrogen and fuel-cell vehicle safety into a new UN Regulation under the 1958 Agreement. Part 1 of Annex 1 uses the numbering system prepared for the corresponding annexes of the International Whole Vehicle Type Approval (IWVTA) regulation (UN R0) currently under development.

Proposal to introduce a definition for “bucket seat” ( front passenger seat having a non-adjustable seat back) which would be exempt from the ISOFIX anchorage requirements. The proposal also exempts certain vehicle/seating configurations from ISOFIX requirements, addressing cases where the vehicle design and purpose mitigate against the use of such child restraints and ISOFIX systems.

Proposal to introduce provisions to prevent the unintentional opening of rear doors while the vehicle is in motion.

Proposal to enable approval testing under UN R137 as an alternative to UN R12 in order to avoid redundant testing requirements. The proposal adds references to the steering gear provisions of UN R137 (full width frontal impact) as a compliance alternative in parallel to the current references similarly allowing compliance via provisions in UN R94 (offset deformable barrier frontal impact). Please note that this proposal is based upon document GRSP-60-06/Rev.1. The reference to GRSP-60-07 is incorrect.

Proposal to consolidate provisions concerning ISOFIX anchorages systems, ISOFIX top tether anchorages and i-Size seating positions removed from Regulation No. 14 in a new regulation. This change removes obstacles to the inclusion of UN R14 into Annex 4 of the future UN Regulation No. 0 of the International Whole Vehicle Type Approval (IWVTA).
