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.
IEC 61587-1 has been prepared by sub-committee 48D: Mechanical structures for electrical
and electronic equipment, of IEC technical committee 48: Electrical connectors and mechanical
structures for electrical and electronic equipment.
This fifth edition cancels and replaces the fourth edition published in 2016. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Modification of title.
b) Revision of Clauses 6, 7 and 8 including new defined test setups.

INTRODUCTION
This document provides a common methodology to perform and report conformance tests of
IEC 60917 or IEC 60297 compliant cabinets, racks, subracks, chassis, chassis integrated
subracks and associated plug-in units under indoor condition use and transportation conditions.
Manufacturers can show the performance and characteristics of products in their catalogues by
using the classifications in accordance with this document.
Users get comparative figures to compare products of different producers and can choose
products for their targeted system from their catalogues. With the information of different
classification levels, they get important indices for the possible maximum loads of the enclosure,
which are important for their individual and safe applicability.
Designers of new products can define the performance requirements of these new products for
their targeted systems by referencing this document. This allows a cost optimized design in
accordance with the intended application.
This edition 5 constitutes a revision of the previous edition, with the following changes:
a) Subracks, chassis with integrated subracks and associated plug-in units
– The static mechanical tests of subracks as described in edition 4 were based on the
inspection of load bearing structural parts (single point load). On the other hand, the
dynamic mechanical load test in edition 4 described not only subracks but also various
types of chassis with integrated subracks, based on the load categories. In addition, the
dynamic mechanical test for plug-in units with mass load was defined. There was no
mention of mechanical tests for chassis.
– This edition 5 provides test methods for static load tests for subracks and chassis
integrated subracks, which are categorized based on subracks’ associated mass loaded
plug-in units. The static load test for chassis is similarly categorized by applying with
dummy loads for chassis. These load categories for subracks, chassis with integrated
subracks and chassis are applied for the dynamic load tests. These test methods solve
previous edition lack of requirements on the static/dynamic tests for subracks and
associated plug-in units, chassis with integrated subrack and chassis.
– Furthermore, a test setup is defined in a test fixture with optional recessed assembly
fixtures at subracks in a housing or rack.
– In the dynamic load tests, the random vibration test is added.
– Specification of individual mechanical tests for plug-in units, which were defined in
edition 4, are required for applications of single board computing system or embedded
systems in relation with applied connector reliability test. The test specification is
introduced as Annex A (normative).
b) Cabinets and racks
– Test setups for the cabinet for different applications, e.g. using a mounting plate, are
added.
– The cabinet/rack samples with different dummy loads have been extended by a test
sample with dummy loads mounted on a mounting plate for industrial electrical
installations.
– The vertical structure test is supplemented instead of the lifting test (LT) of edition 4.
– In the dynamic load tests, the random vibration test is added.
In the revised Clause 9, stability, installation conditions of racks and cabinets are added.

Part 1: Environmental requirements,
test setups and safety aspects

1 Scope
This part of IEC 61587 specifies environmental requirements, test set-ups, as well as safety
aspects for empty enclosures, i.e. cabinets, racks, subracks, chassis, chassis integrated
subracks and associated plug-in units under indoor condition use and transportation. It defines
classifications (product performance levels) for these products, regarding and simulating the
usually arising loads during their use. For mechanical static and dynamic load tests typical
examples with dummy loads are used.
The purpose of this document is to establish defined levels of physical performance in order to
meet certain requirements of manufacture, storage, transport and final location conditions.
This document applies in general only to the above cited mechanical structures.

5 General
These climatic and mechanical tests ensure that the mechanical structure of cabinets, racks,
subracks, chassis integrated subracks, associated plug-in units and chassis will survive the
normal handling during manufacture, storage, transport and final location conditions.
In order to have some safety margin built into the enclosures and related mechanical parts, 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 an ambient (room) temperature range of
nominal +20 °C to +25 °C.
The specified classifications of performance and kinds of tests of this document 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 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 document (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
