- Abstract:
- A new design of 3 kN·m reference torque standard machine was considered. The machine performance is evaluated via inter-laboratory comparison technique using previously calibrated reference torque transducers, one set at the National physical laboratory of Germany (PTB) and the other one calibrated at the accredited laboratory of the English company Norbar. Two loading schemes are used. The first one is slow (5 minutes per calibration step) while the second is a fast one (45 seconds per calibration step). The calibration results revealed good agreement between the designed machine and those of both the PTB and English Norbar.
