Proposal to amend para. 2.9. to define “ISOFIX position” as one that satisfies requirements of this Regulation to allow installation of ISOFIX child restraint systems as defined in UN R44 and UN R129, amend para. 2.24. to define “i-Size seating position” as one that satisfies requirements of this Regulation to allow installation of i-Size child restraint systems as defined in UN Regulation No. 129, amend para. 5.2.2.7. to exclude low ISOFIX anchorages installed in vehicles of category M₂ or M₃ from certain requirements, amend para. 5.2.4.1. to exclude vehicles of category M₂ and M₃ from marking requirements, and amend para. 6.2.5.1. to establish differentiated seat inertia forces for vehicles of categories M₂, N₂, M₃, and N₃. The justification clarifies that the definitions are based on tests fulfilled in this Regulation regarding strength rather than CRS category, addresses that the prior ISOFIX position definition incorrectly allowed i-Size CRS installation in non-i-Size positions, and harmonizes inertia loads for M₂ and M₃ vehicles with UN R14.

Proposal to amend para. 2.27. to redefine “ISOFIX position” as a position satisfying UN R145 requirements to allow installation of ISOFIX child restraint systems as defined in UN R44 and UN R129, amend para. 2.36. to redefine “i-Size seating position” as a position satisfying UN R145 requirements to allow installation of i-Size child restraint systems as defined in UN R129, insert new para. 2.48. defining “Minimum effective seat belt length” as a portion of seat belt webbing usable to restrain an occupant, insert new para. 5.1.11. specifying minimum effective seat belt lengths of at least 2040 mm for 3-point seat belts and 1200 mm for 2-point seat belts in vehicles of categories M₂ and M₃, amend para. 5.2.1. to establish seating position requirements for various child restraint system types by vehicle category, amend para. 5.2.2. to delete reference to manufacturer recommendations, amend para. 5.3.5. to limit information requirements to category M₁ vehicles, insert new para. 11.3. establishing transitional provisions with entry into force of the 02 series of amendments on the official date and mandatory non-acceptance of earlier series approvals issued after 1 September 2030, delete para. 1.2. of Annex 6 Appendix 2, and insert new Annex 8 specifying measurement procedure for minimum effective seat belt length.

Proposal to delete paras. 15.1.2. and 15.1.3., renumber para. 15.1.4. as 15.1.2., and amend the renumbered para. 15.1.2. to provide that as from 36 months after the official date of entry into force of the 06 series of amendments, Contracting Parties applying this Regulation may prohibit the sale of helmets and visors which do not meet the requirements of the 06 series of amendments. The proposal is based on informal document GRSP-78-44 and permits Contracting Parties to issue approvals according to the 05 series of amendments, which aligns with Revision 3 of the 1958 Agreement.

Proposal to transpose GTR-9 Amendment 3 (ECE/TRANS/WP.29/2024/77) on technical requirements for Deployable Pedestrian Protection Systems, amend Chapter 0 Introduction, amend para. 2. to add provisions for vehicles equipped with DPPS and measurements taken with system undeployed, delete footnotes 2 and 3 from para. 2.1., replace reference to 2.27. by 2.29. in para. 2.31., delete footnotes 5 and 6 from paras. 2.43. and 2.45., insert new paras. 2.50. to 2.61. defining DPPS-related terms including Deployment Time, Detection test area, Head Impact Time, Sensors and Testing of DPPS, amend para. 4.2. to delete approval number supplementation provisions, delete para. 4.4.3., amend paras. 5.2. to 5.2.2. to reference Annex 7 requirements when tested with DPPS activated, replace paras. 11.1. to 11.25. with transitional provisions and insert paras. 11.26. to 11.29. establishing that as from entry into force Contracting Parties shall not refuse type-approvals under 05 series amendments, as from 1 September 2031 shall not accept prior series approvals first issued after that date, shall continue accepting prior approvals first issued before 1 September 2031, and shall continue granting approvals using atypical windscreen fracture procedures until 1 September 2033, amend Annex 1 para. 9.23.1., amend text under Annex 2 heading, amend Annex 3 para. 3.2., and insert new Annexes 7 and 8 establishing test procedures for DPPS including prerequisites, HIT verification methods, headform test procedures, HBM qualification, and documentation requirements.

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 amend UN Regulation No. 129 to remove rebound head contact from the head acceleration requirement for all Child Restraint Systems. The regulation currently lacks consistency regarding whether rebound head movement is considered in testing. Variations in test bench design cause booster seats to pass in some laboratories but fail in others based solely on rebound contact. The proposal ensures consistency between different CRS types and reproducibility across laboratories with different test bench designs, and aligns with the approach in UN Regulations 94 and 137.

Proposal to finalize a status report on Amendment 1 to UN Global Technical Regulation No. 20 on electric vehicle safety. The IWG-EVS conducted Phase 2 work addressing topics including water immersion tests, fire resistance, battery rotation and vibration, thermal propagation, and charging safety. The group maintained existing regulatory text except for thermal propagation provisions. Two compliance paths were developed: a physical test method with five initiation options and a risk management approach. Phase 3 will address thermal propagation scope expansion, post-crash safety, in-use battery maintenance, swappable batteries, light vehicles, gas emissions criteria, and bottom protection.

Proposal to amend UN Global Technical Regulation No. 20 on electric vehicle safety, focusing on thermal propagation triggered by single-cell thermal runaway. The amendment introduces two compliance paths: a physical test approach with five initiation methods (external heater, internal heaters, nail penetration, laser-based initiation) performed at vehicle or component level; and a risk management approach requiring manufacturers to document known risks and mitigation strategies. Vehicles must provide advance warning 5 minutes before hazardous conditions (fire, explosion, smoke) occur in the passenger compartment. Phase 2 discussions concluded that water immersion tests, long-term fire resistance tests, REESS rotation tests, vibration profile modifications, AC/DC charging protections, and heavy-duty overcurrent tests do not require regulatory inclusion based on available field evidence and safety analysis.

Proposal to introduce a new paragraph 0.4 clarifying that second-level warnings apply when one seat-belt is unfastened during normal driving, excluding situations of higher priority warnings such as door opening or thermal propagation, to amend the definition of “normal operation” to specify forward motion above 10 km/h without other safety warnings triggered, and modify paragraph 5.2.4.3 to allow discontinuation of second-level warnings when other audible safety warnings are triggered in circumstances of imminent danger.
