The operator looks for a continuous stream of bubbles originating from a specific point on the package. Equipment Required for ASTM D3078 Testing
: As the vacuum level drops, observe the submerged package for bubbles. A continuous stream of bubbles from a specific location indicates a leak.

The 2021 edition more explicitly defines which package types are suitable. It distinguishes between:
This paper provides a comprehensive overview of ASTM D3078, the Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission. As package integrity is paramount in the medical device, pharmaceutical, and food industries, reliable test methods for detecting gross leaks are essential. This review examines the apparatus, procedure, and sensitivity limitations outlined in the 2021 revision of the standard. It compares the vacuum decay bubble emission method with alternative integrity testing technologies and discusses the implications of defect size detection limits on product shelf life and sterility. The operator looks for a continuous stream of
The procedure is rooted in a simple but powerful principle. Here’s a step-by-step breakdown:
Turn off the vacuum. Open the chamber and check the pack for inside fluid, which indicates a leak. 3. Evaluating Results Prices and availability are current as of publication
: Water is standard, though other non-degrading fluids can be used.
The primary objective of the ASTM D3078 protocol is to determine the presence of gross leaks in flexible or semi-rigid packaging that contains a headspace gas.
