Gross Leak Tester
ASTM D3078 is a standard test method for determination of gross leaks in flexible pacakging containing headspace gas by bubble emission. The test is conducted by submerging the packages into water within vacuum chamber. Positive pressure inside the package after the vacuum is drawn may force the package to plug small leaks. If bubbles or seepage of fluid within specimen attributable to a leak are observed, then the specimen fails the test.
Apparatus & Materials
1. Vacuum Chamber - a vacuum chamber should be capable of withstanding approximately one atmosphere pressure differential, fitted with a vacuum-tight cover. A vacuum gage, an inlet tube from a source of vacuum, and an outlet tube to the atmosphere sahll be connected to the chamber cover.
2. Immersion Fluids - usally, we use water as the immersion fluid, which does not degrade the package being tested.
