The test is simple in concept but rigorous in execution: A flexible package is submerged in a liquid (usually water or a surfactant solution) while a vacuum is applied. If the package leaks, bubbles will stream from the defect point. This is commonly known as the or "water immerson test."
While highly effective for gross leaks, ASTM D3078 has specific technical limits.
📌 : If your quality manual references the 2002 version, you are likely already compliant with the 2021 reapproval, as the fundamental methodology remains the same. How the Test is Performed astm d3078 pdf 2021
: The package must contain a headspace gas (air or nitrogen) to function.
The test must be executed systematically to prevent false positives or package distortion. 1. Preparation The test is simple in concept but rigorous
is the industry standard used to detect leaks in flexible packaging using bubble emission. This guide explains the test method, its applications, equipment requirements, and its role in quality control. What is ASTM D3078?
is a standard test method developed by ASTM International that uses bubble emission to detect leaks in flexible packaging that contains a headspace gas. 📌 : If your quality manual references the
is the latest active version of the standard (published 2021). It replaces D3078-02(2013).
