INDUCTIVE COMPONENTS – RELIABILITY MANAGEMENT

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 62211 has been prepared by IEC technical committee 51:
Magnetic components, ferrite and magnetic powder 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) continuous shock and mechanical shock are integrated in the test conditions;
b) the normative references in Table 3 are changed.

FDIS Report on voting
51/1150/FDIS 51/1158/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

INDUCTIVE COMPONENTS – RELIABILITY MANAGEMENT

1 Scope
This document is applicable to inductive components (chokes and transformers) based on
magnetically soft materials. These are components based especially on laminated iron sheets,
iron powder materials (including alloys), as well as ferrites and amorphous or crystalline metal
band cores.
Winding assemblies mean wire winding assemblies as well as multilayer and stacking
technologies of planar technology including coils based on non-magnetic materials. Discrete
type components and the different types of surface mount inductive components (SMD) are
also considered in this document.
The reliability of assemblies of inductive components based on several technologies such as
glued types, types with clamps (clips), impregnated (varnished) types as well as (vacuum)
potted types can also be checked with this document.
The subsequent determinations can be applied either for the primary qualification of inductive
components or for all manners of requalification examinations (design, process, change of
production facility). They can also be applied for the monitoring of products out of actual
manufacturing processes.
This document sets up a broad basis of electric and mechanical criteria of failure test
procedures.
If manufacturers advertise compliance with this standard in their data sheets, customers can
request data to demonstrate compliance with this standard. The customers can also request
the product to be in compliance with this standard by a recognised body.
Customers and manufacturers can elect to perform additional testing and acceptance criteria
different than those defined in this standard.
