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 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 applications. More generalized test procedures are included for the benefit of the R&D engineer and university student. Although the primary concern is with cores of the type used in elec...

This standard specifies applicable tests to describe the significant properties of magnetic cores used in electronic applications. It is primarily concerned with magnetic cores of the type used in electronics transformers, magnetic amplifiers, inductors, and related devices. However, many of the tests specified herein are general in scope and adaptable to magnetic cores used in many other applications. Standards covered by this publication include tests for specifying or measuring, or both, permeability, core loss, apparent core, induction, hysteresis, thermal characteristics, and other properties of all commonly used typoes of magnetic cores.

The purpose of this standard is to present test methods useful in the design, analysis, and operation of magnetic cores in many types of applications in electronics and related industries. Most of the test methods described include specific parameter ranges, instrument accuracies, core sizes, etc., which may be used in the specification of magnetic cores for industrial and military applications. Other sections of the standard describe more generalized test procedures, which are included more for the benefit of the R and D engineer and university student. This standard has been updated to include core materials, test methods, and information on measuring inst...
