A method of compensating for temperature variations in testing part cavities for leaks by placing a fluid pressure source in communication with the cavity and measuring the flow rate to the cavity to determine the rate of any leakage. The method establishes a temperature compensation function by measuring the shift in flow rates resulting from changes in temperature of a sample test part, which temperature compensation function allows correction of the flow rates during subsequent testing according to the sensed temperature of the test part. Flow rates a...
A method of temperature compensating measurements of leak rates from a cavity in a part to be leak tested, said leak rate measurements achieved by placing said cavity in communication with a source of fluid under a predetermined pressure and measuring the flow rate to said cavity from said source, said method comprising the steps of: initially establishing a temperature compensating function by: placing said source of fluid pressure in communication with the cavity of a sample part, at each of a plurality of temperatures of said sample; measuring the shi...
