Metrological certification of measuring instruments according to the concept uncertainty of measurement

Abstract

It is accepted that measurement instruments are technical devices which are characterised by standardised metrological characteristics. The reliability of measurement devices is determined by their ability to withstand the metrological parameters of regulated limits. A result obtained beyond these set boundaries is classified as a metrological failure. The correspondence of metrological characteristics to their standardised values is established during the course of verification (metrological control) or metrological certification of measurement devices.
