適用范圍：This part of IEC 404 specifies the methods used for determining the density, resistivityand stacking factor of electrical steel sheet and strip. These quantities are necessary toestablish the magnetic characteristics of the material. In particular, the density is necessary toallow specified values of the flux density to be set without knowing the thickness of the testspecimen.For the determination of the density, the immersion method was earlier considered to bea fundamental method for use in cases of arbitration. However, experience has shownthat this method is very difficult to use in the case of sheet samples with a relativelylarge surface area. This method is therefore not included. It is described in ISO 2738 and ISO1183.
