Scope

This standard specifies the method for measuring the DC magnetic properties of soft magnetic materials using a ring sample or a permeameter in a closed magnetic circuit. The ring sample method is suitable for stacked ring samples, or overall solid ring samples and sintered ring samples. This standard specifies the following two methods: a) ring sample method, mainly applicable to the measurement of magnetic field strength below 10kA/m; b) magnetic permeability meter method, used for the measurement of magnetic field Measurements between m.
