适用范围：This part of IEC 60404 specifies the general requirements, magnetic properties, geometriccharacteristics and tolerances as well as inspection procedures for pure iron, silicon-iron,nickel-iron and cobalt-iron. The materials are in the form of bar, billet, sheet, strip or wire. Thealloys covered correspond to those defined by classes A, C1, C2, E1 to E4 and F1 to F3 inIEC 60404-1.Magnetic materials used primarily for relays, pure iron and steel products, classified only bycoercivity, are covered in IEC 60404-8-10. IEC 60404-8-10 is less restrictive in terms ofmagnetic properties than the pure iron material (class A) and the silicon-iron alloys (classesC21 and C22) specified in this standard, but it gives more comprehensive dimensionaltolerances.Non-oriented and oriented silicon steels (C21 and C22) for industrial power frequencyapplications, classified by specific total loss, are covered in IEC 60404-8-2, IEC 60404-8-4 andIEC 60404-8-7.Non-oriented and oriented thin magnetic materials for use at medium frequencies, classified byspecific total loss, are covered in IEC 60404-8-8.
