The is the global benchmark for identifying gross leaks in flexible packaging . Officially titled the Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission , this protocol ensures the sterile barrier and physical sealing integrity of pouches, bags, and medical trays across various consumer industries. The ASTM D3078-02(2021)e1 version represents the latest verified technical reapproval, cementing its place in modern quality control workflows.

ASTM D3078-02(2021) outlines a vacuum-based bubble emission test to identify gross leaks in flexible packaging, specifically targeting seals in pouches and blister packs. The procedure requires submerging packages in a vacuum chamber, with limitations noted for small leaks and reliance on operator interpretation. For more details, visit AMETEK MOCON

The utilizes a visual detection method where a package is immersed in a liquid within a vacuum chamber.

Ensure moisture barriers remain intact to protect active ingredients. Tyvek pouches, sterile trays, surgical kit bags Maintain absolute sterility until the point of use. Consumer Goods Wipes packaging, cosmetics tubes, chemical pouches Prevent product leakage during transit and distribution. Conclusion and Compliance astm d3078 pdf 2021

Identify leaks in flexible pouches, bags, and blisters.

Note: Single, isolated bubbles adhering to the outside surface of the package upon submersion are normal air pockets and do not indicate a leak. A true leak produces a steady, repeating stream of bubbles. Step 5: Venting and Inspection

A steady stream of bubbles isolates a specific failure point, or fluid is found inside the package post-test. The is the global benchmark for identifying gross

The operator looks for a continuous stream of bubbles originating from a specific point on the package. Equipment Required for ASTM D3078 Testing

While widely accepted, the bubble emission test has distinct limitations:

Apply vacuum gradually to a predefined level (e.g., 25 inHg for most flexible packages) while observing the package. Ensure moisture barriers remain intact to protect active

ASTM standards undergo periodic reviews and updates to maintain technical accuracy and relevance. Updates and Standards Review

A vacuum pump removes air from the headspace of the chamber above the liquid level.
