Proposal to establish labeling requirements for hydrogen-fueled buses consistent with that existing for LPG-, CNG-, and LNG-fueled buses.

Proposal to align UN R134 with UN R67 and UN R110 with regard to labelling requirements and to assist emergency services in determining appropriate responses in case of fire.

Proposal by the expert from the Netherlands, aiming to achieve an identification of hydrogen-fuelled buses and trucks which is consistent with already existing regulated identification for Liquified Petroleum Gas (LPG), Compressed Natural Gas (CNG) and Liquid Natural Gas (LNG) fuelled buses. The background for the additional labelling would help emergency services to determine how to approach these vehicles in case of a fire. This proposal extends the scope to N2/N3 vehicles due to the wider use and introduces consistency for the installation of labels

Proposal to update the draft 01 series proposal (GRSP/2020/10) to include recommendations with regard to place and dimensions of the labels on vehicles.

Proposal to align UN R134 with UN R67 and UN R110 with regard to labelling requirements and to assist emergency services in determining appropriate responses in case of fire.

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.

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

The task force works on the improvement of UN Regulation no. 134 and a potential new UN Regulation on liquefied hydrogen
