An important procedural note: both the test sample and the test fluid must be at equilibrium with normal room temperature to ensure consistent results.
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?
ASTM D3078 – 19(2021): Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission Target Audience: Quality Control Managers, Packaging Engineers, Regulatory Compliance Officers
If a leak exists, internal air will escape, creating a continuous or localized stream of bubbles.
Understanding ASTM D3078 in context often requires familiarity with complementary standards.
: Water is standard, though other non-degrading fluids can be used.
