ASTM D is a standard test method for determination of gross leaks in flexible pacakging containing headspace gas by bubble emission. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

The size of the leak that can be detected is dependent upon the products contained, the nature of the packaging material, and the test parameters selected. This abstract is a brief summary of the referenced standard. The test is conducted by submerging the test specimen in the immersion fluid within the confines of a vacuum chamber. The test sample and test fluid shall be at equilibrium with normal room temperature. If bubbles or seepage of fluid within specimen attributable to a leak are observed, then the specimen fails the test.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. A vacuum gage, an inlet tube from a source of vacuum, and an outlet tube to the atmosphere shall be connected to the chamber cover.
