Design of Torque Standard Machine for Calibration of Reference Torque Wrench at NIM

Meng Feng, Zhang Zhimin, Li Tao, Lin Jing
  • Abstract:
    The paper describes the design of a new torque standard machine at NIM. This machine is used to calibrate the reference torque wrench and torque transducer. The measurement uncertainty is expected to reach 0.03 % (k = 2). The range is designed from 10 N · m to 5000 N · m.
