scope:

This publication outlines the service conditions expected for the system and various system components in a portable, reversible metal hydride system to be used for hydrogen storage. These systems do not include metal hydride battery systems.

This publication provides service conditions that are the basis for the design, manufacture, inspection, testing, and approval of the system and system components used with one or more chemical compounds generally described as a metal hydride.

Where appropriate, the specific component or a specific application is indicated; otherwise, the conditions of service for these systems apply to each component in all such services. Where known, system or component features are provided with minimum requirements.
