- This European Standard defines the general principles of the measurement of the magnetic properties of electrical sheets and strips by means of a single sheet tester and gives the technical details of the measurement of specific total loss and of magnetic field strength, excitation current and specific apparent power. This European Standard is applicable at power frequencies to: a) grain oriented magnetic sheet and strip: - for the measurement between 1,0 T and 1,8 T of: - specific total loss; - specific apparent power; - r.m.s. value of the magnetic field strength; - for the measurement up to peak values of magnetic field strength of 1000A/m of: - peak value of the magnetic polarization; - peak value of the magnetic field strength; b) non-oriented magnetic sheet and strip: - for the measurement between 0,8 T and 1,5 T of: - specific total loss; - specific apparent power; - r.m.s. value of excitation current; - for the measurement up to peak values of magnetic field strength of 10000A/m of: - peak value of the magnetic polarization; - peak value of the magnetic field strength. The single sheet tester is applicable to test specimens obtained from electrical sheets and strips of any quality.The magnetic characteristics are determined for a sinusoidal induced voltage,for specified peak values of magnetic polarization and for a specified frequency. The measurements are made at an ambient temperature of 23°C±5°C on test specimens which have first been demagnetized.
