Abstract

Inter-laboratories comparison of reference torque wrench calibration was conducted between the NMIJ and the PTB using a torque transducer with the form of torque wrench, TTS/100Nm, the rated capacity of which was 100 N·m, as a transfer device. Under various calibration conditions, the calibration results obtained by both laboratories were coincided within the range of uncertainties of measurement.
