ABSTRACT:
In measuring the rate of leak from a test object, a conduit system including branch lines interconnects the test object with a measuring tank, a pressure gauge, a vacuum pump and a device for removing vapor from the measuring tank. Valves in the conduit system permit the various parts to be selectively interconnected or separated. By measuring the pressure in the measuring tank under various conditions it is possible to determine the rate of leak.
