Friday 5 June, morning session (9:30–12:30): items may be discussed depending on progress.

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.
