This Standard specifies the measuring methods of density, resistivity and stacking factor of electrical steel strip and sheet.
These quantities are necessary to establish the magnetic characteristics of the material.
In particular, the density is necessary to allow specified values of the magnetic flux density to be set without knowing the thickness of the test specimen.
For the measurement of the density, the immersion method was earlier considered to be a fundamental method.
However, experience has shown that this method is very difficult to use in the case of the test specimen with a relatively large surface area.
This method is therefore not included in this Standard, It is described in ISO 1183 and ISO 2738.
NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
IEC 60404-13 : 1995 Magnetic materials – Part 13 : Methods of measurement of density, resistivity and stacking factor of electrical steel sheet and strip (MOD)
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
