Abstract

International measurement comparisons are important to demonstrate the technical competence of calibration laboratories, to experimentally confirm the measurement uncertainties and to demonstrate the equivalence of national measurement standards and traceability schemes in accreditation systems. The network of international comparison schemes in general and the specific issues of gauge block comparisons in particular are presented. An overview on different comparisons which were carried out in the past few years on a regional and a worldwide scale is given for both, gauge block measurements by interferometry and by comparison.
