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. R3078 Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Nonporous materials were not part of the round robin testing. It is informational only and not an official part adtm the standard; the full text of the standard itself must be referred to for its use and application.
Vacuum sealed pouches might require a different approach. This abstract is a brief summary of the referenced standard. Any masking that is done can have an effect on the ability of the user to recognize pinholes in the material surface. Positive pressure inside the pouch after the vacuum is drawn may force the product to plug small leaks. 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.
If there is no gas within the package to create the pressure against the hole, this ashm not be an effective test. There is an ASTM bubble emission test for flexible qstm device packaging that uses internal pressurization to detect gross leaks in tray or pouch packages. Need help or have a question? The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
ASTM D3078 – 02(2013)
With the first vacuum is taken low enough to allow any remaining air in the package to expand against any pinholes or channel. ASTM D is a standard test method for determination of gross leaks in flexible pacakging containing headspace gas by bubble emission.

Depending on the degree of vacuum packing, if the leak is large enough the change in appearance in the vacuum pack may be visible in a short period of time. There are many issues that can come up with either choice- amount of vacuum inside the package, the package design, shape or configuration, the flexibility of the materials all of which need to be taken into consideration.
The first method F breaks the vacuum and inflates the package. Vacuum or pressure decay both non-destructive tests function by creating a pressure differential. Is there a standard for bubble emission testing that does not require using something like polycrylic to mask the surface? A vacuum chamber shall be any transparent container capable of withstanding approximately one atmosphere pressure differential, fitted with a vacuum-tight cover. Vacuum Chamber – a vacuum chamber should be capable of withstanding approximately one atmosphere pressure differential, fitted with a vacuum-tight cover.
This may give you an answer on the package integrity but is probably not the information you would be looking for to determine the effectiveness of the vacuum packaging.
The test is conducted by submerging the packages into water within vacuum chamber. Viscoelastic effects on the products, or entrapped air, become significant and prevent passage through small openings.
