23、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 co
24、nditions 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 N
25、ational 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
26、 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
27、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
28、 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
29、 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
30、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
31、the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data
32、of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC/TR 62131-2, which is a technical report, has been prepared by IEC technical committee 104: Environmental conditions, classification and methods of test. TR 62131-2 IEC:2011(E)
33、5 The text of this technical report is based on the following documents: Enquiry draft Report on voting 104/507/DTR 104/536/RVC Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publication has been drafte
34、d in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 62131 series, under the general title Environmental conditions Vibration and shock of electrotechnical equipment, can be found on the IEC website. The committee has decided that the contents of this publication w
35、ill 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 amended. A bilingual version of this standard may
36、 be issued at a later date. 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 TR 62131-2 IEC:2
37、011(E) ENVIRONMENTAL CONDITIONS VIBRATION AND SHOCK OF ELECTROTECHNICAL EQUIPMENT Part 2: Equipment transported in fixed wing jet aircraft 1 Scope IEC/TR 62131-2, which is a technical report, reviews the available dynamic data relating to electrotechnical equipment transported in fixed wing jet tran
38、sport aircraft. The intent is that from all the available data an environmental description will be generated and compared to that set out in IEC 60721. For each of the sources identified the quality of the data is reviewed and checked for self consistency. The process used to undertake this check o
39、f data quality and that used to intrinsically categorize the various data sources is set out in IEC/TR 62131-1. This technical report primarily addresses data extracted from a number of different sources for which reasonable confidence exist as to their quality and validity. The report also presents
40、 data for which the quality and validity cannot realistically be reviewed. These data are included to facilitate validation of information from other sources. The report clearly indicates when it utilizes information in this latter category. This technical report addresses data from several differen
41、t transport aircraft 1 . Although one of these aircraft is no longer used commercially, data from it are included to facilitate validation of information from other sources. Relatively little of the data reviewed has been made available in electronic form. To permit comparison, a quantity of the ori
42、ginal (non-electronic) data have been manually digitized in this technical report. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the
43、 referenced document (including any amendments) applies.
