The pressure-decay leak test is a standard non-destructive quality assurance procedure used to verify the hermetic integrity of sealed containers. By monitoring the rate of pressure loss within a fixed volume, engineers can quantify the leak rate to ensure product shelf-life and prevent contamination.
