Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 1: General specification
IEC 63093-1:2020 specifies the dimensions and allowable limits of surface irregularities of ferrite cores.
It is intended that this document excludes ferrite cores which are specialty cores with limited use. Also, special cores which are only marginal variations upon standard cores are excluded.
IEC publishes electrical standards for families of ferrite cores, as well as this series of dimensional standards for families of ferrite cores. Modifications to the ferrite cores listed in one type of standard are reflected in the other type.
This document is considered as a general specification useful in the dialogue between ferrite core suppliers and users about surface irregularities.
This first edition cancels and replaces the second edition of IEC 60424-1 published in 2015 and the first edition of IEC 62317-1 published in 2007. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous editions of IEC 60424-1 and IEC 62317-1:
a) this document integrates IEC 60424-1 and IEC 62317-1.
Noyaux ferrites - Lignes directrices relatives aux dimensions et aux limites des irrégularités de surface - Partie 1: Spécification générale
L'IEC 63093-1:2020 spécifie les dimensions et les limites admissibles des irrégularités de surface des noyaux ferrites.
Il est prévu que le présent document exclue les noyaux ferrites qui sont des noyaux spécialisés dont l'utilisation est limitée. En outre, les noyaux spécialisés qui ne présentent que des variations marginales par rapport aux noyaux normalisés sont exclus.
L’IEC publie des normes électriques pour des familles de noyaux ferrites, ainsi que cette série de normes sur les dimensions pour des familles de noyaux ferrites. Les modifications apportées aux noyaux ferrites énumérés dans un type de norme sont reproduites dans l'autre type.
Le présent document est considéré comme une spécification générale utile au dialogue entre les fournisseurs de noyaux ferrites et leurs utilisateurs, portant sur les irrégularités de surface.
Cette première édition annule et remplace la deuxième édition de l’IEC 60424-1 parue en 2015 et la première édition de l’IEC 62317-1 parue en 2007. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport aux éditions précédentes de l’IEC 60424-1 et l’IEC 62317-1:
a) le présent document réunit l’IEC 60424-1 et l’IEC 62317-1.

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 63093-1 has been prepared by IEC technical committee 51:
Magnetic components, ferrite and magnetic powder materials.
This first edition cancels and replaces the second edition of IEC 60424-1 published in 2015
and the first edition of IEC 62317-1 published in 2007. This edition constitutes a technical
revision.
This edition includes the following significant technical changes with respect to the previous
editions of IEC 60424-1 and IEC 62317-1:
a) this document integrates IEC 60424-1 and IEC 62317-1.
