This part of IEC 62044 specifies measuring methods for power loss and amplitude permeability
of magnetic cores forming the closed magnetic circuits intended for use at high excitation levels
in inductors, chokes, transformers and similar devices for power electronics applications.
The methods given in this document can cover the measurement of magnetic properties for
frequencies ranging practically from direct current to 10 MHz, and even possibly higher, for the
calorimetric and reflection methods. The applicability of the individual methods to specific
frequency ranges is dependent on the level of accuracy that is to be obtained.
The methods in this document are basically the most suitable for sine-wave excitations. Other
periodic waveforms can also be used; however, adequate accuracy can only be obtained if the
measuring circuitry and instruments used are able to handle and process the amplitudes and
phases of the signals involved within the frequency spectrum corresponding to the given
magnetic flux density and field strength waveforms with only slightly degraded accuracy.
NOTE It can be necessary for some magnetically soft metallic materials to follow specific general principles,
customary for these materials, related to the preparation of specimens and specified calculations. These principles
are formulated in IEC 60404-8-6.
