Measurement Uncertainty Analysis of a Transfer Standard Force Calibration System
Force transducer calibration may be performed by means of dead weights or by comparison with a transfer standard. Directly applied dead weights with traceability to the National Institute of Standards and Technology (NIST) are primary force standards. Low-capacity force transducers are generally calibrated by primary standards, but for force transducer calibrations above 1000 lb (453.6 kg), many force transducers are calibrated by means of secondary force standards used as transfer standards. The purpose of this paper is to provide a measurement uncertainty analysis of transfer standard force calibration at one test facility. Significant error sources are identified and quantified. The methodology presented is generally applicable; however, the error evaluations are specific to the measurement process and test equipment used.
