A transparent container filled with water, connected to a vacuum pump. Water: Serving as the submerged medium to detect bubbles. Vacuum Gauge: To monitor the pressure inside the chamber.

If a leak exists, internal air will escape, creating a continuous or localized stream of bubbles. astm d3078 pdf 2021
is the definitive international standard for detecting gross leaks in flexible packaging by bubble emission . Reapproved by ASTM International with minor editorial updates, this protocol outlines the "vacuum immersion" or "bubble leak" test. It serves as a foundational quality control metric for food, pharmaceutical, medical device, and consumer goods industries to ensure seal integrity and maximize product shelf life.
The primary goal of the ASTM D3078 test is to detect in packaging that contains a headspace gas. It is particularly effective for identifying issues such as: Weak or uneven heat seals Pinholes or punctures caused by handling Misaligned closures and material defects in film Key Sensitivity Limits: A transparent container filled with water, connected to
No. For rigid containers, refer to (vacuum testing of rigid containers) or ASTM D3079 (dry testing). D3078-21 explicitly covers flexible and semi-rigid pouches.
