Abstract

Key and supplementary comparisons are of interest to the metrology community because they provide the means of demonstrating the degree of equivalence between the measurement capabilities of national metrology institutes. In recent years, NIST has been involved in both key and supplemental comparisons for DC resistance in the range 1 ?? to 1 G??. While participating in and piloting several of these comparisons, much has been learned, and as a result, both the comparison process and our view of this process has evolved. Topics that will be addressed here include development of protocols, characterization of standards, statistical analysis approaches, and the present status of several comparisons in the area of DC resistance.
