This part of IEC 60404<\/span> <\/span> specifies the general requirements, magnetic properties, geometric characteristics 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. The alloys covered correspond to those defined by classes A, C1, C2, E1 to E4 and F1 to F3 in IEC 60404\u20111<\/span> <\/span>.<\/p>\n

Magnetic materials used primarily for relays, iron and steel products, classified only by coercivity, are covered in IEC 60404\u20118\u201110<\/span> <\/span>. IEC 60404\u20118\u201110<\/span> <\/span> is less restrictive in terms of magnetic properties than the irons (class A) and the silicon steels (classes C21 and C22) specified in this standard, but it gives more comprehensive dimensional tolerances.<\/p>\n

Non-oriented and oriented silicon steels (C21 and C22) for industrial power frequency applications, classified by specific total loss, are covered in IEC 60404\u20118\u20113<\/span> <\/span>, IEC 60404\u20118\u20114<\/span> <\/span> and IEC 60404\u20118\u20117<\/span> <\/span>.<\/p>\n

Non-oriented and oriented thin magnetic materials for use at medium frequencies, classified by specific total loss, are covered in IEC 60404\u20118\u20118<\/span> <\/span>.<\/p>\n
