Provisional agenda for GRSP’s eightieth session to be held 7–11 December 2026 in Geneva. The session will address UN Global Technical Regulations No. 1, 13, and 20; UN Regulations Nos. 11, 17, 21, 22, 95, 100, 127, 129, 134, 145, 170, 173, and 174; a new UN Regulation and authorization request for a GTR on children left in vehicles; collective amendments to UN Regulations affecting automated vehicles; Mutual Resolution No. 1; equitable occupant protection; and other business items including vehicle automation, software updates, airbags, child restraint systems, and bus protection.

The task force completed working documents for transposition of the optional part of GTR 13 on liquefied hydrogen (GRSP/2025/41, GRSP-78-15/Rev.1, GRSP-78-16/Rev.2), updating ISO 17268-1:2025 references for receptacle geometry, and incorporating ISO 19887-1:2024 and periodic inspection requirements into UN Regulation No. 134 (WP.29/2026/56, WP.29/2026/136, WP.29/2026/57). The task force recommended deferring discussions on supply line standards to IWG GTR 13 Phase 3 and provided recommendations for hydrogen storage and fuel system requirements.

Proposal to insert a new chapter P and paragraphs 247 and 248 establishing that supply lines for additional TPRDs are constructed from metallic materials with further investigation required for other materials in the next phase, and requiring manufacturers to provide handling procedures to ensure supply lines will not suffer damage or contamination during handling with removal from service of lines with unacceptable damage, exclude the drop test from the requirements at para. 51., and amend para. 81. (c) (i) to clarify that drop impact testing applies to containers without supply lines and valves with damage to supply lines or valves requiring replacement.
