IEEE Standard for Test Procedures for Magnetic Cores

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 electronics transformers, magnetic amplifiers, inductors, and related devices, many of the tests are adaptable to cores used in many other applications.

Standard for Test Procedures for Magnetic Cores

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, 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. Test methodologies covered by this standard include tests for specifying or measuring, or both, permeability, core loss, flux density, hysteresis, saturation characteristics, thermal characteristics, and other properties of all commonly used types of magnetic cores.
