Sample Preparation: The flexible package is filled with a specific amount of air (if not already filled) to ensure the walls do not collapse under vacuum.
Submersion: The package is submerged in a transparent tank filled with water. The water level should be roughly 1 inch (25 mm) above the package.
Vacuum Application: A vacuum is drawn in the chamber above the water. The standard specifies test vacuum levels (typically ranging from 5 to 30 inHg, or 170 to 1000 mbar) based on the expected seal strength and defect size.
Observation: The vacuum is held for a specified dwell time. The operator observes the package through the transparent walls of the chamber.
Leak Identification: A leak is indicated by a continuous stream of bubbles emanating from a specific point. Random bubbles caused by trapped air on the package surface are ignored; only steady streams indicate a defect.
Release: The vacuum is released, and the package is removed.
