Scope: This calibration system table is suitable for the calibration of measuring instruments with force value (≤1 MN). It stipulates the purpose and composition of the national benchmark for force values, the complete set of basic measuring instruments included in the benchmark, the metrological performance of the benchmark and the procedure for transmitting the unit magnitude of the force value to the working measuring instruments through the measurement standard, and specifies its uncertainty and Basic testing methods, etc. In the entire force calibration system, force standards can be divided into two categories. The first type is a fixed standard that generates force values. This type of standard machine is divided into static weight type, lever type, hydraulic type and superposition type isoforce standard machine according to the structure. The second category is various portable standards that transmit force values. This kind of standard instrument can be divided into standard force measuring instruments such as dial indicator type and strain gauge according to its measurement principle.
