適用范圍：The purpose of this part IEC 404 is to define the method of measurement of the magnetic polarization and the magnetic field strength and also the determinatin of the demagnetization curve and recoil line of permanent magnet materials, such as those specified in IEC 404-8-1, the properties of which are presumed homogeneous throughout their volume.The performance of a magnetic system is not only dependent on the properties of the permanent magnet material but also on the dimension of the system, the air-gap and other elements of the magnetic circunit.The method s described in this standard refer to the measurement of the magnetic properties in a closed magnetic circuit simulating a ring.
