OBS

Pressure decay has been the most widely used method of leak testing in manufacturing production lines for decades. The process is uncomplicated, inexpensive and easily automated. Air is injected into a test object, and any decrease in air pressure over time signifies a leak. However, the pressure decay method has limited sensitivity and is unable to determine the location of leaks.
