Differences between ASTM E331 & ASTM E1105

Link to Active This link will always route to the current Active version of the standard. In service, the performance will also depend on the rigidity of supporting construction and on the resistance of components to deterioration by various causes, vibration, thermal expansion and contraction, etc.

These factors should be fully considered prior to specifying the test pressure difference to be used. This test method does not address these issues. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

Included diagrams show these differences. Professional services based on accurate information that helps you or your company make the right decision regarding your project or asset.

ASTM E 331

The ASTM E testing is performed by applying water to the exterior of the test specimen while lowering the pressure inside by means of an air chamber built on the inside or opposite side of the test specimen.
