ISO 16111:2008
Transportable gas storage devices — Hydrogen absorbed in reversible metal hydride
ISO 16111:2008 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 (250 bar).
It only applies to refillable storage MH assemblies where hydrogen is the only transferred media. Storage MH assemblies intended to be used as fixed fuel-storage onboard hydrogen fuelled vehicles are excluded.
ISO 16111:2008 is intended to be used for certification purposes.
