CSA CHMC 1-12

Scope

This standard provides uniform test methods for evaluating material compatibility with compressed hydrogen applications. The results of these tests are intended to provide a basic comparison of materials performance in applications utilizing compressed hydrogen. This standard is not intended to replace the targeted testing which may be necessary to qualify the design of a component manufactured for use in hydrogen applications.

This standard applies to metallic materials only.

If the value for measurement as given in this standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.

All references to pressure throughout this standard are to be considered gauge pressures, unless otherwise specified.
