: Seal the chamber and begin the vacuum pull.
While the standard does not prescribe universal test parameters, it provides a robust framework that laboratories can adapt to their specific packaging configurations—making it an essential tool in any quality assurance program where package integrity is critical.

The American Society for Testing and Materials (ASTM) developed the ("Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission") to solve this issue.
: If a package is vacuum-packed with zero headspace, there is no air to "push out," making this test ineffective. : Seal the chamber and begin the vacuum pull
This article provides an in-depth look at this standard, covering its purpose, procedure, significance, and how to access the revision. What is ASTM D3078-02(2021)?
A critical aspect of utilizing ASTM D3078 is understanding its sensitivity limits. The test is highly effective for detecting leaks larger than 125 µm (0.005 in.), though with optimal conditions and surfactants, leaks as small as 50–75 µm may be detected.

To provide context for ASTM D3078, it is useful to compare it with other ASTM standards for package integrity:
