X. Hu, Y. Wang, F. Bao, W. Huang


To estimate the situation of torque standard machines in different provinces’ laboratories within China, a torque standard comparison was carried out, for the first time. Results were obtained and then analysed, with values of En being calculated. The characteristics and the performance of the torque transfer standard transducer were indicated. We also discuss some problems during the comparison.
