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 sound engineering judgment; additional testing considerations may be necessary to fully qualify the design of a component manufactured for use in certain 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.

Project need:

To update the current standard due to user experience/feedback/new technology (new edition).

 

This proposed  New Edition is being developed at the request of industry interested parties. It will provide the industry with.  a conformity assessment document to support consistency in testing of metallic materials.

 

This will meet the strategic needs of the following key interests:

  1. ensuring that the latest innovative/technology/safety features are available for users,
  2. addressing needs of regulators by providing suitable requirements; and   
  3. supporting certification bodies.
