Description
OPERATION
The sample is submerged into the vacuum vessel filled with a mixture of water and dye. Vacuum is created inside the vessel and maintained for a specific length of time. When vacuum is released, any punctured package will draw in dye revealing the imperfect seal. According to ASTM D 3078
