This calibration system table is suitable for calibration and value transmission of torque measuring instruments. It stipulates the purpose of the national torque benchmark, the metrological parameters of the benchmark and the procedure for transmitting the torque unit value to working measuring instruments with the help of measurement standards, and specifies its uncertainty and basic calibration methods. When performing calibration, it is also used as the basis for traceability of value.
