is the active international standard for the Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission . This standard, which was reapproved in 2021, defines a critical visual inspection process used primarily to identify gross leaks in flexible or semi-rigid packaging that contains headspace gas. Core Purpose of ASTM D3078

To improve bubble visibility, the standard recommends using a wetting agent (surfactant) in the water. The 2021 update includes more specific instructions on surfactant concentration and water temperature to ensure repeatability across labs. Increase the vacuum level gradually to the targeted

No continuous bubbles are observed during the vacuum hold, and no fluid enters the package after pressure equalization.

: The test package (pouch) is placed inside a special vacuum chamber ——a transparent container designed to withstand significant pressure differences. The chamber is then filled with a test fluid (usually water) until the package is fully submerged. It's crucial that this fluid does not react with or degrade the package material.
