Yes, many medical device manufacturers use it for of pouches and trays, but only for gross leaks. For sterile barrier validation, combine it with a more sensitive method (e.g., dye ingress per ASTM F1929).

A continuous stream of bubbles indicates a leak. astm d3078 pdf 2021
: If the package has a leak, the pressure differential forces the internal headspace gas to escape through the opening. This escaping gas forms a visible stream of bubbles in the liquid. The location, size, and onset time of these bubbles are then observed and recorded to identify and characterize the leak.
: Record the type of leak (e.g., pinhole, seal defect, corner split), its location, and the vacuum level at which bubbles first appear. Yes, many medical device manufacturers use it for
What are you testing (e.g., food, medical devices)?
The importance of ASTM D3078 extends far beyond general packaging, particularly in highly regulated industries like medical devices. The U.S. Food and Drug Administration (FDA) formally recognizes ASTM D3078-02(2021)e1 as a . This means that for many Premarket Submissions (like 510(k)s), using this test method provides a recognized and acceptable way to demonstrate package integrity. A continuous stream of bubbles indicates a leak
A year in parentheses indicates the year of last reapproval.
is the industry standard for determining leaks in flexible packaging by bubble emission . The most recent major revision of this standard provides definitive guidelines for quality control laboratories to verify package integrity. Ensuring a seal is airtight prevents contamination, preserves product freshness, and extends shelf life. What is ASTM D3078?
