It is a used to detect gross leaks in sealed flexible packages. The principle is simple yet effective: a sealed package is submerged in a liquid (usually water or a surfactant solution), and a vacuum is applied. If the package leaks, bubbles will escape from the defect point.
If you are searching for , you likely need the official document for compliance, audit preparation, or implementing a leak test protocol. This article will explain everything you need to know: what the standard covers, the key changes in the 2021 version, how to legally obtain the PDF, and how to apply it in real-world testing. What is ASTM D3078? ASTM D3078 is titled: "Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission." astm d3078 pdf 2021
Introduction In the world of packaging integrity, ensuring that a sealed package is free from leaks is not just a quality metric—it is a safety imperative. For industries ranging from food and beverage to pharmaceuticals and medical devices, a pinhole leak can lead to product contamination, oxygen ingress, moisture loss, and ultimately, a costly recall.

Hold the vacuum for the specified dwell time (typically 30–60 seconds, but can be longer per internal protocols).
Observe for a continuous stream of bubbles emerging from a single point. Intermittent bubbles may indicate trapped surface air; steady bubbles confirm a leak.
