NZS ISO 16111:2024
Transportable gas storage devices – Hydrogen absorbed in reversible metal hydride
Standard specifies the requirements applicable to the material, design, construction, and testing of transportable hydrogen gas storage systems, referred to as metal hydride (MH) assemblies, which utilise shells not exceeding 150 litres’ 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 medium. It is not applicable to storage MH assemblies intended to be used as fixed fuel-storage aboard hydrogen-fuelled vehicles.
The standard was prepared by the P3652 Hydrogen Standards Committee and is identical to and has been reproduced from ISO 16111:2018, Transportable gas storage devices – Hydrogen absorbed in reversible metal hydride.
