Vacuum testing is when a pre-made pouch is tested by filling it with air and submerging it in a water bath using a plate to hold it under water. 15 to 20 Hg (inches of mercury) is drawn by vacuum on the tank and the tank is inspected for air bubbles. Air bubbles would indicate air is escaping the pouch and identify any leaks.
