The achievable test sensitivity is limited to or even less, as indicated by the recent interlaboratory test referenced in Section 12 of the standard. This sensitivity level is appropriate for identifying gross leakage issues that would compromise product integrity, sterility, or shelf life.
The standard provides but allows modification based on package sensitivity.
ASTM D3078-2021 has been harmonized with international standards, particularly ISO 23867-2 ( Leak test method for flexible packaging — Part 2: Bubble test ). This helps global manufacturers maintain compliance across regions. astm d3078 pdf 2021
A vacuum gauge, an inlet tube from a vacuum source, and an outlet tube to the atmosphere are connected to the chamber cover. The inlet and outlet tubes must be equipped with hand valves. Additionally, a transparent plate is attached to the underside of the cover, positioned such that when the chamber is two-thirds filled with fluid, the plate sits approximately 1 inch (25 mm) below the fluid surface.
ASTM D3078 is a standardized test method developed by ASTM International. It is designed to identify gross leaks in flexible, non-porous packaging that contains a headspace of gas. The core principle is simple and visually effective: a package is submerged in water and placed in a transparent vacuum chamber. When a vacuum is drawn, the pressure differential forces any air inside the package to escape through leaks, creating a stream of bubbles. The presence of these bubbles indicates a failed seal. The achievable test sensitivity is limited to or
It detects by immersing the package in a liquid (usually water) after creating a vacuum. Escaping gas forms bubbles, indicating the location and relative size of leaks.
