27、mmission (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 an
28、d 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 Committe
29、e 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 accord
30、ance 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 inte
31、rested 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 respons
32、ible 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
33、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 o
34、f 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 an
35、d 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 Publica
36、tion 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 Publica
37、tion may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61587-5 has been prepared by subcommittee 48D: Mechanical structures for electronic equipment, of IEC technical committee 48: Electromechanical compon
38、ents and mechanical structures for electronic equipment. The text of this standard is based on the following documents: FDIS Report on voting 48D/549/FDIS 48D/553/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.

39、his publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 61587-5 IEC:2013 5 A list of all parts of IEC 61587 series, under the general title Mechanical structures for electronic equipment Tests for IEC 60917 and IEC 60297, can be found on the IEC website. The committee has
40、 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 a
41、mended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 61587-5 IEC:2013 INTRODUCTION This s
42、tandard is based on IEC 61587-2: Mechanical structures for electronic equipment Tests for IEC 60917 and IEC 60297 Part 2: Seismic tests for cabinets and racks and ATIS-0600329:2008:Network Equipment Earthquake Resistance. This standard sets forth test setups, performance requirements, and acceptance
43、 criteria for determining the robustness of chassis, subracks, and associated plug-in units according to the IEC 60297 and IEC 60917 series that may provide a level of survivability and preserve functionality during and after a seismic occurrence (an earthquake). This standard does not replace regio
44、nal seismic system, installation standards, or specifications. The intent of this standard is to provide a common methodology to perform and report seismic test conformance of chassis, subracks, and plug-in units according to the IEC 60297 and IEC 60917 series within a specified weight category. Mas
45、s distribution is based on the intended use. The terms “intended use” or “simulation of service condition” or “worst-case simulated configuration” are widely used in the telecom industry but also in the electronics industry. Seismic ground motion occurs simultaneously and randomly in all directions.
46、 Single-axis or tri-axis tests may be selected to simulate the seismic environment for testing. 61587-5 IEC:2013 7 MECHANICAL STRUCTURES FOR ELECTRONIC EQUIPMENT TESTS FOR IEC 60917 AND IEC 60297 Part 5: Seismic tests for chassis, subracks and plug-in units 1 Scope and object This part of IEC 61587
47、specifies seismic test requirements for chassis, subracks, and plug-in units as defined in the IEC 60297 and IEC 60917 series. It applies in whole or in part, only to the mechanical structures of chassis, subracks, and plug-in units for electronic equipment, according to the IEC 60297 and IEC 60917
48、series, and does not apply to electronic components, equipment or systems within the mechanical structures. NOTE Subracks may be an integral part of a chassis (often called in the industry a shelf or a crate). The object of this standard is to establish a level of physical integrity of chassis, subr
49、acks, and plug-in units according to IEC 60297 and IEC 60917 series that may provide a level of survivability that will preserve functionality during and after a seismic occurrence. It is intended to provide the user with a high level of confidence in the selection of an equipment practice to meet such needs. Since IEC 60297 and IEC 60917 series chassis, subracks, and plug-in units come in m
