22、TERNATIONAL ELECTROTECHNICAL COMMISSION _ MECHANICAL STRUCTURES FOR ELECTRONIC EQUIPMENT OUTDOOR ENCLOSURES Part 3: Environmental requirements, tests and safety aspects FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all nati
23、onal 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, Technica
24、l 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. I
25、nternational, 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
26、 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 recommendatio
27、ns 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 us
28、er. 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
29、 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 c
30、ertification 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
31、 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 referen
32、ces 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 id
33、entifying any or all such patent rights. International Standard IEC 61969-3 has been prepared by subcommittee 48D: Mechanical structures for electronic equipment, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment. This second edition cance
34、ls and replaces the first edition issued in 2001. It constitutes a technical revision. The main technical changes with regard to the previous edition are as follows. Table 1 and Table 6 have been extended with requirements and tests, relevant for outdoor conditions. 4 61969-3 IEC:2011 The text of th
35、is standard is based on the following documents: FDIS Report on voting 48D/483/FDIS 48D/497/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 IEC 61969 series, under the general title Mechani
36、cal structures for electronic equipment Outdoor enclosures, 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 o
37、n 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. 61969-3 IEC:2011 5 INTRODUCTION IEC 61969-3 Ed.2.0 provides basic environmental test requirements
38、 to be used in the absence of local regulatory or application specific environmental test requirements. This provides manufacturers and users of generic outdoor enclosure solutions with minimum performance compliance criteria; thermal solutions pending on the environment an outdoor enclosure is subj
39、ected to. Since forced air heat dissipation and acoustic noise are closely related, noise limitations are typically defined by local regulatory limitations. Typically, it becomes the responsibility of the outdoor enclosure vendor to provide a solution for thermal management within the local regulato
40、ry noise limitations. 6 61969-3 IEC:2011 MECHANICAL STRUCTURES FOR ELECTRONIC EQUIPMENT OUTDOOR ENCLOSURES Part 3: Environmental requirements, tests and safety aspects 1 Scope This part of IEC 61969 specifies a set of basic environmental requirements and tests, as well as safety aspects for outdoor
41、enclosures under conditions of non-weatherprotected locations above ground. The purpose of this standard is to define a minimum level of environmental performance in order to meet requirements of storage, transport and final installation. It is the intention to establish basic environmental performa
42、nce criteria for outdoor enclosure compliance. 2 Normative references The following referenced documents are indispensable for the application of this document.
