This part of IEC 60404 is applicable to Fe-based amorphous strips specified in IEC 60404-8- 11 for the measurement of AC magnetic properties at frequencies up to 400 Hz.<\/p>\n

The object of this part is to define the general principles and technical details of the measurement of the magnetic properties of Fe-based amorphous strips by means of a single sheet tester.<\/p>\n

The single sheet tester is applicable to test specimens obtained from Fe-based amorphous strips of any quality. The AC magnetic characteristics are determined for a sinusoidal induced voltage, for specified peak values of magnetic polarization and for a specified frequency.<\/p>\n

The measurements are made at an ambient temperature of (23 \u00b1 5) \u00b0C on test specimens which have first been demagnetized.<\/p>\n

\n

NOTE 1 The single sheet tester specified in this document is appropriate for other materials which have magnetic properties and physical characteristics similar to those of Fe-based amorphous strip, such as nano-crystalline soft magnetic strip. The single sheet tester for electrical steel sheets is specified in IEC 60404-3.<\/p>\n<\/blockquote>\n

\n

NOTE 2 Throughout this document the term \u201cmagnetic polarization\u201d is used as described in IEC 60050-121. In some standards of the IEC 60404 series, the term \u201cmagnetic flux density\u201d is used.<\/p>\n<\/blockquote>\n
