Torque standard comparison among provinces laboratories in China
Xueqin Hu, Yi-Xu Wang, F. Bao, Wuhong Huang · ACTA IMEKO · 2020
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 E n being calculated. The characteristics and the performance of the torque transfer standard transducer were indicated. We also discuss some problems during the comparison.
