Abstract

The paper describes a new multifunction torque standard machine at NIM. National institute of Metrology has established a multifunction torque standard machine. It has three main functions. One is hydraulic torque wrench calibration. The second function is torque multiply calibration. The third function is reference torque standard machine. This paper introduces the structure and the working principle of the equipment, performance parameters and the uncertainty evaluation.
