A METROLOGIST ANALYSIS OF INTERNATIONAL WRITTEN STANDARDS AND GUIDES RELEVANT TO MEASUREMENT IN CHEMISTRY

Franco Pavese

Abstract

This paper, starting from reviewing basic concepts, such as repeatability, reproducibility, accuracy, systematic error, true value, bias, Type A and B uncertainty components, as defined in international documents, shows that, currently, full consensus and a common understanding seems not be achieved yet. This fact reflects on the process of combining data, namely in chemistry.

Keywords

repeatability, reproducibility, accuracy, Type A uncertainty component, Type B uncertainty component
