Force Measurements at NMI

摘要

The revised Australian Standard AS 2193 for the calibration of force measuring systems has set specified uncertainty values of the applied forces as a criterion for calibrating these instruments. The force capability at the National Measurement Institute (NMI) has been upgraded by means of two force standards to cover forces up to 4.5 MN in compression with a level of accuracy to meet these changes and the needs of force measurement in Australia. The establishment of the two force standards based on build-up technique is described. The status of calibration capabilities at NMI and the development of a 3.5 MN force standard are presented.
