Terms and nomenclature for cores made of magnetically soft ferrites - Part 3: Guidelines on the format of data appearing in manufacturers' catalogues of transformaer and inductor cores

This part of IEC 60401 gives guidelines for a uniform method of presentation for the
properties of magnetically soft ferrite materials and measuring conditions under which they
should be determined. It is intended for use in manufacturers' catalogues of transformer and
inductor cores, in order to aid the comparability of such data. Additional guidance is given for
users and manufacturers concerning testing and specification of reliability for ferrite cores and
for devices using ferrite cores.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60401-3 has been prepared IEC technical committee 51: Magnetic

components and ferrite materials.

This second edition cancels and replaces the first edition published in 2003. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) addition of reliability in Clause 6.

INTRODUCTION

For various reasons, a manufacturer may wish to publish in its catalogue typical data for

material parameters as measured on test pieces. It is the object of this part of IEC 60401 to

promote the comparability of such information in the area of soft ferrite materials.

Except for several specific property limits that should be given separately for each particular

core, the properties described in this standard are material characteristics, intended to

facilitate meaningful evaluation of ferrite materials. It should be recognized, however, that

there is no direct relation between material characteristics as measured on test pieces and

the corresponding parameters measured on other cores, made of the same material, because

of differences in geometry and variation in production processes. Also, the extrapolation of

material characteristics to other flux densities and other frequencies will not permit valid

comparison of cores of different materials under these new conditions of operation.

It is therefore emphasized that it is impossible to design and specify a core on the basis of

material properties published by a manufacturer in its catalogue, without due contact with that

manufacturer. Also, the publication of material characteristics should not be considered as a

guarantee for core properties; for this purpose, only the specification of that core should be

used.

It is strongly recommended that, together with the material characteristics, manufacturers

publish a note covering the two statements above on the limitations of this kind of information.
