IEC 60404-3:1992+A1:2002+A2:2009 defines the general principles and the technical details of the measurement of the magnetic properties of magnetic sheets, at power frequencies, by means of a single sheet tester. This tester is applicable to flat plate specimens obtained from magnetic sheets and strips of any quality. The magnetic characterictics are determined for a sinusoidal induced voltage, for specified peak values of magnetic polarization and for a specified frequency. This consolidated version consists of the second edition (1992), its amendment 1 (2002), its amendment 2 (2009) and its corrigendum (2009). Therefore, no need to order amendments in addition to this publication.< /b>
