This part of IEC 60404 specifles the general requirements,magnetic properties,geometric characteristics and tolerances as well inspection procedures for pure iron,silicon-iron,nickel-iron and cpbalt-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,E1to E4 and F1 to F3 in IEC 60404-1.
Magnetic materials used primarily for relays,pure iron and steel products,classified only by coercivity,are covered in IEC 60404-8-10.IEC 60404-8-10 is less restrictive in terms of magnetic properties than the pure iron material (class A)and the silicon-iron alloys(classes C21 and C22)specified in this standard,but it gives more comprehensive dimensional tolerances.
Non-oriented and oriented silicon steels(C21 and C22)for industrial power frequency applications,classified by specific total loss,are covered in IEC 60404-8-2,IEC 60404-8-4 and IEC 60404-8-7.
Non-oriented and oriented thin magnetic materials for use at medium frequencies,classified by specific total loss,are covered in IEC 60404-8-8
