Abstract

An analysis of gauge block calibrations by mechanical comparison carried out at METAS with several sets of gauge blocks during several years has demonstrated very small variations. It is shown, that under optimum conditions with respect to laboratory environment and instrumental equipment as well as by following a suitable handling and measurement procedure, the contribution in the uncertainty budget added by the mechanical comparison process to the uncertainty of the interferometrically calibrated reference gauge blocks can be very small.
