ABSTRACT:
A sealed container having a test port with a membrane which is pervious to gas and impervious to liquid may be tested by connecting a pressure device such as a vacuum pump or pressure pump to the test port and creating a pressure differential between the container side of the membrane and the pump side of the membrane, allowing the pressure differential to equalize through the membrane and monitoring the equalized pressure to detect whether or not the equalized pressure changes, which utilmately allows the observer to determine whether the sealed container has any leaks. If the pressure equalization time is substantially zero, the membrane and/or membrane seal is defective. In the event a leak is determined, the inside of the radio device may be pressurized to a selected pressure, by use of a pressure pump or the like, and then immersed in a liquid such as water. The location of the leak may then be detected by observing the emanation of air bubbles from that portion of the device in which the leak exists.
