AS ISO 16111:2020
[Current]Transportable gas storage devices — Hydrogen absorbed in reversible metal hydride
This Standard adopts ISO 16111:2018, which defines the requirements applicable to the material, design, construction, and testing of transportable hydrogen gas storage systems, referred to as “metal hydride assemblies” (MH assemblies) which utilize shells not exceeding 150 L internal volume and having a maximum developed pressure (MDP) not exceeding 25 MPa. This document is applicable to refillable storage MH assemblies where hydrogen is the only transferred media. This document is not applicable to storage MH assemblies intended to be used as fixed fuel-storage onboard hydrogen fuelled vehicles.
