20、 10 61969-1 IEC:2011 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ MECHANICAL STRUCTURES FOR ELECTRONIC EQUIPMENT OUTDOOR ENCLOSURES Part 1: Design guidelines FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national elect
21、rotechnical 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 Specific
22、ations, 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. Internation
23、al, 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 de
24、cisions 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 int
25、ernational 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
26、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
27、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 certificati
28、on 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, p
29、roperty 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
30、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
31、any or all such patent rights. International Standard IEC 61969-1 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 cancels and rep
32、laces the first edition issued in 1999. It constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: a) Addition of design guidance for thermal management and noise suppression as thermal/noise management is often considered a basic requirement
33、of an empty outdoor enclosure. If thermal management components are included in the product, the environmental impact may become the responsibility of the empty outdoor enclosure manufacturer. Therefore the acoustic limitations shall be observed. 4 61969-1 IEC:2011 Typically, the user of the empty o
34、utdoor enclosure follows the local regulatory acoustic requirements (sound power and/or sound pressure). Acoustic measurements may be performed on the empty outdoor enclosure fitted with thermal management components only or, if agreed between manufacturer and user at the final stage of the applicat
35、ion specific installation. b) Historically, Ed 1 intended to create a market for standardized empty outdoor enclosures offered by multiple vendors. Detail standards such as IEC 61969-2-1 Ed 1 and IEC 61969-2-2 Ed 1 were issued to guide users to preferred and available solutions. However, development
36、 showed that this intend (created with users participation) was not satisfying the users expectations. Consequently, the detail standards IEC 61969-2-1 Ed 1 and IEC 61969-2-2 Ed 1 will be withdrawn when IEC 61969-2 Ed 2 is issued. The IEC 61969-2 Ed 2 co-ordination dimensions are based on IEC 60917-
37、1. The definition outdoor cases and outdoor cabinets are merged into the definition outdoor enclosures. The text of this standard is based on the following documents: FDIS Report on voting 48D/488/FDIS 48D/498/RVD Full information on the voting for the approval of this standard can be found in the r
38、eport on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 61969, under the general title, Mechanical structures for electronic equipment Outdoor enclosures, can be found on the IEC website. The commit
39、tee 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 editio
40、n, or amended. 61969-1 IEC:2011 5 INTRODUCTION This standard is intended as a generic guide for the development of further standards. The products covered are empty enclosures to be equipped with application-specific solutions to be used at non-weather protected locations above ground. This standard
41、 is followed by a co-ordination dimension standard (IEC 61969-2 Ed 2) and an environmental requirements and tests, safety aspect standard (IEC 61969-3 Ed 2). 6 61969-1 IEC:2011 MECHANICAL STRUCTURES FOR ELECTRONIC EQUIPMENT OUTDOOR ENCLOSURES Part 1: Design guidelines 1 Scope This part of IEC 61969
42、contains design guidelines for outdoor enclosures and is applicable over a wide field of mechanical, electromechanical and electronic equipment and its installation where a modular design is used. The objective of this standard is to provide an overview of specifications for enclosures focused on re
43、quirements for outdoor applications for stationary use at non-weather protected locations. These enclosures are considered to contain any equipment and provide protection for the outdoor installed facilities against unwanted environmental impacts. The installed equipment may be, but is not limited t
44、o, subracks according to IEC 60917-2-2 or IEC 60297-3-101. A typical outdoor enclosure is shown in Figure 1.
