In order to establish a determination method of uncertainty for the static torque calibration, the validity of probability distributions was verified by the numerous repetition of torque measurement using the primary torque standard machine. In the 1st report, assumed probability distributions were investigated for repeatability with unchanged mounting position, reproducibility with changed mounting position and zero error. This paper describes results of experimental confirmation for other uncertainty contributions: interpolation error, hysteresis (reversibility) and resolution including the ability of the indicator. Total uncertainty for calibration of the torque measuring device is also calculated and the determination method is proposed.
