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.

Request for authorization to develop test procedures to assess the mechanical integrity and durability of supply lines to any additional Thermally activated Pressure Relief Devices (TPRD) connected directly to the Compressed Hydrogen Storage System (CHSS).

Procedural request for authorisation to introduce provisions for supply lines between compressed hydrogen storage systems (CHSS) and their thermally activated pressure relief devices (TPRD) based on the outcomes from the transposition of GTR-Phase 2 (Amendment 1) transposition into UN R134.

Proposal to amend UN R134 regarding hydrogen and fuel cell vehicles. The amendment clarifies requirements for supply lines serving additional thermally activated pressure relief devices (TPRDs) on compressed hydrogen storage systems. It specifies that supply lines must be constructed from metallic materials, demonstrate mechanical integrity through qualification tests excluding drop tests, and establishes handling procedures to prevent damage. The proposal also defines container attachments and refines test procedures for burst pressure, drop impact, permeation, and localized leak testing.

Request to amend GTR 13 to align the GTR with technical progress and remove inconsistencies between Parts I and II of Amendment 1.
