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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

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 and ferrite materials.
The text of this standard is based on the following documents:
FDIS Report on voting
51/724/FDIS 51/739/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 2005.

At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INDUCTIVE COMPONENTS –
RELIABILITY MANAGEMENT
1 Scope

This International Standard is applicable to inductive components (chokes and transformers)

based on magnetically soft materials. These are especially components based on laminated

iron sheets, iron powder materials (including alloys), as well as ferrites and amorphous or

crystalline metal band cores.

Winding assemblies means wire winding assemblies as well as multilayer and stacking

technologies of planar technology including the coil based on non-magnetic materials.

Discrete type components and the different types of surface-mountable inductive components

(SMD) are also considered in this standard.

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 standard.

The subsequent determinations can be applied either for the primary qualification of inductive

components or for all ways 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 standard 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 may

request data to demonstrate compliance to this standard. The customers may also request the

product to be in compliance to this standard by a recognised national institute.

Customers and manufacturers may elect to perform additional testing and acceptance criteria

different than those defined in this standard.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
reliability of inductive components

component level reliability of the inductive component in the customers’ electrical circuit

application
3.2
component level reliability tests

sequence of tests performed on an individual component, each specific test being designed to

represent conditions under which the component is expected to operate in end applications

NOTE Categories of test levels are organised to be consistent for typical applications.

3.3
system level reliability tests

sequence of tests performed on a collection of components as arranged in a specific end

application under working conditions
3.4
component family

group of components characterised by the same common features, for example the same

magnetic base material, the same core size and the same winding type
---------------------- Page: 11 ----------------------
62211 © IEC:2003 – 13 –
4 Component families

In a similar way to the qualification rules contained in IEC 61248, reliability tests can be

performed on typical samples representing families of inductive components.
A family of inductive components is defined on the basis of:
– the same application class as specified in the IEC 61248 series;

– the same magnetic base material group (for example ferrite, metal powder, etc.);

– the same core shape (for example E-type, RM, ring core, etc.);
– the same winding type (for example wire-wound, multilayer, stack, etc.);
– the same termination configuration (PTH, SMD etc.);
– comparable accessories
