Установление пригодности откалиброванного средства измерений на основе определения вероятности соответствия его метрологических характеристик требованиям технической документации

Abstract

The provisions of European and international normative documents reviewing the conformity assessment of the object under investigation with the requirements of technical documentation are considered. It is noted that, in contrast to the verification procedure for measuring instruments used in the field of legal metrology, the verification procedure for calibrated measuring instruments must take into account the measurement uncertainty. The expressions for estimating the probability of compliance of the measuring instruments of the metrological requirements for distribution laws that are different from normal are obtained. A procedure for evaluation the probability of compliance for an arbitrary law of distribution of a measurand, based on the Monte Carlo method is developed. Examples of calculating the probability of compliance a calibrated caliper are given.
