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 % (<i>k</i> = 2). The range is designed from 10 N &middot; m to 5000 N &middot; m.
