Submerge the sealed package completely. Ensure it is fully immersed and free of external air bubbles.
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. astm d3078 pdf 2021
One of the most trusted global standards for detecting such leaks is . Specifically, the 2021 edition of this standard introduced critical updates that refine how flexible, porous, and non-porous packages are tested. Submerge the sealed package completely
Note: None of these are direct substitutes; selection depends on your package material and sensitivity requirement. The release of ASTM D3078-2021 was not a minor editorial update. It brought clarity, alignment with ISO methods, and practical improvements that reduce false failures and improve reproducibility across laboratories. The principle is simple yet effective: a sealed
Hold the vacuum for the specified dwell time (typically 30–60 seconds, but can be longer per internal protocols).
