Two comparison measurement techniques were developed and tested by the Physical Metrology Laboratory at Rocky Flats for the calibration of nitrogen leaks. The first technique uses a simple rate-of-rise measurement, whereas the second is based upon comparison of ultimate pressures attainable within a well-defined vacuum chamber. Both methods were originated to provide a relatively fast and accurate means of leak rate determination, which is traceable to the Primary Standards Laboratory, Albuquerque, New Mexico. Theoretical and operational fundamentals of each method along with their test results are compiled. 2 refs., 3 figs., 3 tabs.
