Feature Selective Validation applied to the comparison of calibration data

This paper presents an alternative application of the Feature Selective Validation (FSV) for comparing metrological data such as those coming from calibration certificates, standard references and historical records of intermediate verifications. Through the examples developed in this work, it is shown how the FSV method can be used to study the drift of the characteristic response of a measuring device, transducer or accessory, allowing identifying when the deviations observed are unacceptable requiring performing adjustments within the measurement chain. This approach can also be used to measure the improvement on a calibration method or of an specific condition of it.
