Mechanical structures for electronic equipment - Tests for IEC 60917 and IEC 60297 - Part 2: Seismic tests for cabinets and racks

IEC 61587-2:2011 specifies seismic tests for cabinets and racks accommodated with IEC 60917 and 60297 series. It applies, in whole or in part, only to the mechanical structures of cabinets and racks for electronic equipment according to the above cited series of standards, while it does not apply to the electronic equipment or systems deemed to be installed within these mechanical structures. This standard does not apply either to a cabinet or a rack having an anti-seismic isolation structure, either external or internal. This standard aims to provide test conditions and criteria that constitute a reference to evaluate the ability of the mechanical structure of the cabinets or racks to acceptably withstand specified seismic intensities. For this purpose, this standard specifies test specimen conditions, such as dimensions (i.e. height, width and depth) of the cabinet and the rack, load distribution, structural test condition and the RRS (required response spectra) of single-axis or tri-axis acceleration as the seismic test wave condition. The single-axis or tri-axis acceleration is selectable. The second edition of this standard replaces the first edition published in 2000 and constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: Edition 1.0 specified the test condition with one size of the cabinet, and one load distribution. The specified acceleration condition for the test specimen was single-axis and one of the RRS (required response spectra) specified in the standard was selected. The test was aimed to obtain the reference for the structural strength of the enclosure against the specified seismic intensity. Earthquakes are actually random phenomena that are much more carefully simulated by tri-axial simultaneous operation. The demand of tri-axial excitation has emerged as a more accurate representation of an earthquake.

Structures mécaniques pour équipements électroniques - Essais pour la CEI 60917 et la CEI 60297 - Partie 2: Essais sismiques pour baies et bâtis

La CEI 61587-2:2011 spécifie les essais sismiques pour les baies et les bâtis des séries CEI 60917 et 60297. Elle s'applique, totalement ou partiellement, seulement aux structures mécaniques des baies et des bâtis pour les équipements électroniques conformes aux séries de normes précitées, mais elle ne s'applique pas aux équipements ou systèmes électroniques destinés à être installés à l'intérieur de ces structures mécaniques. La présente norme ne s'applique pas non plus à une baie ou un bâti équipé d'une structure d'isolation anti-sismique, qu'elle soit externe ou interne. La présente norme est destinée à fournir des conditions et des critères d'essai qui constituent une référence pour évaluer l'aptitude de la structure mécanique des baies ou des bâtis à résister de manière acceptable à des intensités sismiques spécifiées. Dans ce but, la présente norme spécifie des conditions pour le spécimen en essai, comme les dimensions (c'est-à-dire hauteur, largeur et profondeur) de la baie et du bâti, la répartition de charge, la condition de l'essai structurel et le SRS (spectre de réponse spécifié) de l'accélération à axe unique ou sur les trois axes comme condition d'onde d'essai sismique. Il est possible de choisir entre accélération à axe unique ou sur les trois axes. Cette deuxième édition annule et remplace la première édition parue en 2000, dont elle constitue une révision technique. Les principaux changements techniques par rapport à l'édition précédente sont les suivants: L'édition 1.0 spécifiait la condition d'essai avec une taille de baie et une répartition des charges. La condition d'accélération spécifiée pour le spécimen soumis à l'essai était monoaxiale et un des SRS (spectre de réponse spécifié) spécifiés dans la norme était choisi. L'essai était destiné à obtenir la référence pour la résistance structurelle de l'enveloppe par rapport à l'intensité sismique spécifiée. Les tremblements de terre sont réellement des phénomènes aléatoires qui sont bien mieux simulés par un fonctionnement sur les trois axes simultané. Le besoin d'une excitation sur les trois axes a émergé pour une évaluation plus approfondie des tremblements de terre.

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 61587-2 has been prepared by subcommittee 48D: Mechanical
structures for electronic equipment, of IEC technical committee 48: Electromechanical
components and mechanical structures for electronic equipment.
The second edition of this standard replaces the first edition issued in 2000 and constitutes a
technical revision.
The main technical changes with regard to the previous edition are as follows:
Edition 1.0 specified the test condition with one size of the cabinet, and one load distribution.
The specified acceleration condition for the test specimen was single-axis and one of the RRS
(required response spectra) specified in the standard was selected. The test was aimed to
