ASTM D3078 Flexible Packaging Bubble Emission

Testing Standard:

ASTM D3078 Test Method for Determination of Leaks in Flexible Packaging (Bubble Emission)

Standard Number
ASTM D3078

Standard Title
Test Method for Determination of Gross Leaks in Flexible Packaging Containing a Headspace Gas by Bubble Emission

Overview for ASTM D3078:

ASTM D3078 is a test method that is helpful by way of vacuum in detecting small leaks. Purple Diamond Testing offers ASTM D3078 Testing as part of our packaging compliance and validation services. The Gross Leak Test is a standard test method for determining if there are any leaks in the packaging of a product. The test itself is done by submerging the sample package into water while it is in the vacuum chamber. If there are any leaks at all, the pressure from the vacuum chamber will cause or force the package to actually plug smaller leaks in the packaging. If there are bubbles or seepage of fluid within the sample package, then the actual test has failed and the packaging needs to be re-designed. 

Materials Used for ASTM D3078: 

As mentioned, Purple Diamond Laboratory uses a vacuum chamber to perform this standard test. There is an immersion fluid necessary to finish this test. Mostly water is used as the immersion fluid. This particular immersion fluid does not degrade the package being tested. 

Rationale:

ASTM D3078 – Determination of Gross Leaks in Flexible Packaging (Bubble Emission). This test method is performed by submerging the sample package in water or other liquid, a vacuum is introduced, and any leakage will be evident by a steady stream of bubbles.
