초록

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...
