Abstract

The full suite of tools for the evaluation of statistical consistency of metrological data is applied to the data set compiled from two recent international comparisons: CCT-K7 and EURAMET.T-K7. This paper illustrates how insights into lab measurement characteristics such as repeatability, reproducibility, secular uncertainties and laboratory equivalence statements can be obtained in a statistically-rigorous manner.
