JJG 2045-2010 Measuring Instruments for Force(≤1 MN)

Scope

This verification system table is applicable to the verification of force measurement instruments (≤1 MN). It specifies the purpose and composition of the national reference standard for force measurement, the complete set of basic measurement instruments included in the reference standard, the metrological performance of the reference standard, and the procedure for transferring the unit value of force from the metrological standard to working measurement instruments. It also indicates their uncertainty and basic verification methods, etc.
In the entire force verification system, force standard instruments can be divided into two categories. The first category is fixed standard instruments that generate force values. These standard instruments are divided into static weight-type, lever-type, hydraulic-type, and superposition-type force standard machines according to their structure. The second category is various portable standard instruments that transfer force values. These standard instruments can be divided into dial gauges, strain gauges, and other standard force measuring instruments according to their measurement principles.
