Laminations for transformers and inductors for use in telecommunication and electronic equipment IEC 60740:1982 ED1

Publication date:   Jan 1, 1982

Scope

Specifies the preferred sizes, and their associated tolerances, of lamination of various shapes made from magnetic sheets or alloys of specified composition and thicknesses, their marking and packing, and also simple test methods for determining the electrical properties of cores made from such laminations. The principal application for laminations complying with this specification is for transformers and inductors used in telecommunications and electronic equipment employing similar techniques.
