and safety aspects for cabinets, racks, subracks
and chassis under indoor conditions


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 61587-1 has been prepared by IEC sub-committee 48D:
Mechanical structures for electronic equipment, of IEC technical committee 48:
Electromechanical components and mechanical structures for electronic equipment.
This third edition cancels and replaces the second edition published in 2007. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
1) Rephrasing “performance level” by “classification”.
2) Reference to fire hazard testing according to IEC 60695-11-10 in 8.2.1.
3) Intended applications replaced by application examples.

FDIS Report on voting
48D/481/FDIS 48D/495/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.
A list of all parts of the IEC 61587 series, under the general title Mechanical structures for
electronic equipment – Tests for IEC 60917 and IEC 60297 series, can be found on the IEC
website.
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.

1 Scope and object
This part of IEC 61587 specifies environmental requirements, test set-up, as well as safety
aspects for empty enclosures, i.e. cabinets, racks, subracks and chassis under indoor
conditions.
The purpose of this standard is to establish defined levels of physical performance in order to
meet certain requirements of storage, transport and final location conditions. It applies in
whole or part only to the mechanical structures of cabinets, racks, subracks and chassis, but
it does not apply to electronic equipment.

3.2
test sample
the unit under test, dummy loaded where necessary in order to achieve realistic results
4 Classification of environmental conditions
The climatic conditions are derived from IEC 60721-3-3 and IEC 60654-4.
The shock and vibration conditions are derived from IEC 60721-3-3.

The product specification in accordance with this standard may use the one or other severity
class. Combinations are also permitted.
5 General
The purpose of the mechanical tests is to ensure that cabinets, racks, subracks and chassis
will survive the normal handling during manufacture, storage, transportation, installation and
in the service environment.
In order to have, for the enclosure itself, some safety margin built-in, all classification
parameters are higher than parameters for the overall application itself. This should ensure
proper working of a complete unit in an application.
Unless otherwise specified all tests shall be done at room temperature (+20 °C – 25 °C).
The specified classifications of performance and kinds of tests of this standard can be
combined as required. Compliance to individual subclauses and levels is permissible.
Individual tests and severities are referred to by letters and numbers (see Table 1 for
examples which show a selection of representative and well-known values from each
subclause and relevant table).
The various tests should be performed using the same sample wherever it is possible.
Experience has shown that the sequence of tests listed in this standard (see also
IEC 60068-1) enables the test sequence to be performed using the same test sample except
where the individual test results preclude further testing of the same sample, i.e. the test
damages (destroys) the sample.

6.1 General
It is the objective of the climatic tests to ensure that cabinets, racks and subracks will survive
the particular environment in which they will normally operate without degradation or creating
a hazard.
Climatic tests shall be selected by reference to the application examples given in Table 2 for
cabinets, racks and subracks.
In order to claim compliance at a given level, all test criteria for that requirement level shall be
met.
