Over deze norm
IEC 60404-10 is applicable to grain-oriented and non-oriented electrical steel strip and sheet for measurements of a.c. magnetic properties in the frequency range 400 Hz to 10 000 Hz. The object of this document is to define the general principles and the technical details of the measurement of magnetic properties of electrical steel strip and sheet by means of an Epstein frame. The Epstein frame is applicable to test specimens obtained from electrical steel strips and sheets of any grade. The AC magnetic characteristics are determined for sinusoidal induced voltages, for specified peak values of magnetic polarization and for a specified frequency. The measurements are to be made at an ambient temperature of (23 ± 5)°C on test specimens which have first been demagnetized. - THIS REDLINE VERSION PROVIDES YOU WITH QUICK AND EASY WAY TO COMPARE ALL THE CHANGES BETWEEN THIS STANDARD AND ITS PREVIOUS EDITION. A VERTICAL BAR APPEARS IN THE MARGIN WHEREVER A CHANGE HAS BEEN MADE. ADDITIONS AND DELETIONS ARE DISPLAYED IN RED, WITH DELETIONS BEING STRUCK THROUGH.
