Abstract

1 kN·m universal torque calibration machine with reference torque transducer was established at National Measurement and Calibration Center (SASO / NMCC) in 2019. Torque values are generated over reference torque transducers by means of a servo motor. The machine is equipped with an air bearing and a torque arm mounting component. It is possible to calibrate torque transducer, torque wrench with high accuracy and also hand torque tools with this machine. In this paper, the mechanical structure of the machine and the result of the performances test and uncertainty assessment are described. The relative expanded measurement uncertainty is smaller than 2 × 10^-4.
