GB/T 13888-2009
AbolishedMethod of measurement of the coercivity of magnetic materials in an open magnetic circuit
在开磁路中测量磁性材料矫顽力的方法
Application Summary AI generated
This standard specifies a method for measuring the coercivity of magnetic materials using an open magnetic circuit configuration, eliminating the need for a closed magnetic yoke. It is primarily applied in the quality control and material characterization of permanent magnets, soft magnetic materials, and electrical steel sheets used in motors, transformers, and magnetic sensors. The method is particularly useful for industrial testing environments where rapid, non-destructive evaluation of magnetic properties is required without complex sample preparation.
