Astm D3078 !new! Jun 2026

The ASTM D3078 procedure requires a vacuum chamber, a transparent lid (or a chamber with viewing windows), and a suitable immersion fluid (typically water). The general procedure is as follows:

ASTM D3078 specifies a procedure for detecting leaks in sealed flexible, porous, or non-porous packages. The test involves:

ASTM D3078 is a standard developed by ASTM International (formerly the American Society for Testing and Materials). It describes a method for detecting gross leaks in flexible packaging by submerging the package in a liquid and applying a vacuum.

Key factors influencing sensitivity include:

While effective, ASTM D3078 is not without limitations:

The sensitivity of the test depends heavily on the test parameters, specifically the vacuum level. The standard suggests that with optimal conditions, the method can detect holes as small as a specific micron diameter (often cited around 50 to 125 microns depending on the specific apparatus and product headspace).

The ASTM D3078 standard, titled is one of the most widely used protocols for evaluating the seal integrity of flexible containers. By detecting micro-leaks through a simple yet effective vacuum-induced bubble emission process, this method ensures that products—ranging from food to medical devices—remain protected from contamination and environmental degradation. Core Methodology: The Bubble Emission Test

: If there is a leak in the seal or the package wall, the internal gas will escape and appear as a steady stream of bubbles rising through the liquid.
