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
