EXPERIENCE WITH A NEW 1 GPa STANDARD OF THE CMI

Abstract

The expansion of the high technology leads to the increasing demands for the calibration services in the extremal pressure ranges, both vacuum and high gauge pressure in liquid medium. The presentation will deal with the second one, focusing on the solution chosen by the Czech Metrology Institute (CMI) to improve its services in the range of gauge pressure from 0.5 GPa to 1 GPa. A new high-pressure standard will be described, and its first evaluation outlined.
