This Technical Specification defines the requirements applicable to the safe design and use of transportable
hydrogen gas storage canisters, including all necessary shut-off valve, pressure-relief devices (PRD), and
appurtenances, intended for use with reversible metal hydride hydrogen storage systems. This Technical
Specification only applies to refillable storage canisters where hydrogen is the only transferred media. Storage
canisters intended to be used as fixed fuel storage onboard hydrogen fuelled vehicles are excluded.
