ASTM D3078

Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission

Test Materials

ASTM D3078 specifies the use of packaging materials such as plastic films, bottles, and containers that are subjected to leak testing. The test evaluates the ability of the packaging to resist leaks under vacuum or pressure conditions. Materials should be prepared to ensure uniformity and consistency for accurate results.

Test Process

The packaging leak test involves placing the sample in a controlled chamber, where a vacuum or pressure is applied. The test checks for leaks by monitoring the pressure change or detecting bubbles in the sample. The method ensures that the container remains sealed under specified conditions, simulating real-world handling and storage.

Test Result Interpretation

Test results from ASTM D3078 are interpreted by measuring the degree of pressure change or leak detection over a set time. A significant change in pressure or the presence of bubbles indicates a leak, while minimal change suggests the packaging is intact. The results help assess the packaging’s ability to maintain product integrity during distribution and storage.
