Statistical Analysis of 2 MN and 4 MN Force Range Key Comparisons

T. Bartel
Abstract:
The factors contributing to the uncertainty are discussed for the measurements that were conducted for the 2 MN and 4 MN force values of the very high force key comparison administered by the Comité International des Poids et Mesures (CIPM). Details of the statistical analysis by the pilot institute, NIST, are provided. Various options for calculating the reference values and degrees of equivalence are presented, accounting for the uncertainty differences associated with the comparison force transfer standards and with the force standard machines of the participating National Metrology Institutes (NMI).
Keywords:
