Abstract
Bilateral comparisons of the calibration of low nominal capacity torque measuring devices (TMDs) were conducted between NMIJ and PTB for the first time. A 10Â NÂ m deadweight torque standard machine (TSM) newly developed at NMIJ was compared with PTB's two TSMs with nominal capacities of 1Â NÂ m and 1Â kNÂ m, in the range from 0.1Â NÂ m to 10Â NÂ m. The transfer measurement devices used had nominal capacities of 1Â NÂ m and 10Â NÂ m. The comparisons were made using two calibration procedures: one based on the CCM.T-K2 Key Comparison procedure and the other according to the daily calibration procedure adopted at each institute. As a result, the torque realized by the TSM at NMIJ was shown to be equivalent to that realized by the two TSMs at PTB. In addition, it was confirmed that the daily calibration procedures of both institutes yielded consistent results in the calibration of low nominal capacity TMDs.
