Methods of determining the confidence level in the evaluation of the expanded uncertainty of measurement of vibration acceleration

Abstract

The technique of determining the confidence level in the evaluation of the expanded uncertainty of measurement of vibration acceleration in view of the risks of metrological producer and consumer, that can reasonably set the interval around the measurement result within which most probably located the distribution of values that can be attributed to the measurand. The characteristics of the changes meteorological risks producers and consumers, depending on the ratio between the value of standard deviation error, which has developed means of measuring of vibration acceleration and established consumer MSE value. Based on the metrological characteristics of the changes risk can be graphically set the value of the confidence level.
