Introducing the concept of “uncertainty in measurement” into domestic metrological practice

Abstract

There are four options for introducing the uncertainty concept in Russia. Preference is given to the gradual replacement of “error characteristic,” “total mean-square error,” and “confidence limits of error” by the terms “uncertainty,” “combined standard uncertainty,” and “expanded uncertainty,” respectively. The incorrect and widespread perception that “uncertainty in measurement” is an alternative for “error” is pointed out.
