4、June 27,1991 IEEXStandardsBoard Approved December 9,1991 American National Standards Institute - Abstract: Test methods useful in the design, analysis, and operation of magnetic cores in many types of applications are presented. Tests for specifying and/or measuring permeability, core loss, apparent
5、 core loss, induction, hysteresis, thermal characteristics, and other properties are given. Most of the test methods described include specific parameter ranges, instrument accuracies, core sizes, etc., and may be used in the specification of magnetic cores for industrial and,military ap- plications
6、. More generalized test procedures are included for the benefit of the R equivalent CGS and English units are included in some definitions. Whenever possible, all definitions and symbols are in accordance with those of the International Electrotechnical Commission (IEC). The revision of this standar
