Abstract

A method for the evaluation of international comparison results is demonstrated via detailed consideration of the CCL-K2 Key Comparison of long gauge block calibration. Although CCL-K2 involves a geometrically simple length measurand, associated with it are many of the difficult measurement issues often encountered in international comparison exercises.
