28、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
29、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
30、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 or
31、ganizations. 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 fo
32、rm 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 misinterpret
33、ation 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 r
34、egional 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 o
35、ut 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 Committe
36、es 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 th
37、e 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
38、 responsible for identifying any or all such patent rights. International Standard IEC 60068-2-60 has been prepared by IEC technical committee 104: Environmental conditions, classif ication and methods of test. This third edition cancels and replaces the second edition, published in 1995, and consti
39、tutes a technical revision. This edition includes the f ollowing signif icant technical changes with respect to the previous edition: updated IEC f ormat; updated normative ref erences list; addition of inf ormation of the working volume; revision of the test procedure; revision of the f igures in A
40、nnex B. International Electrotechnical Commission 4 IEC 60068-2-60:2015 IEC 2015 The text of this standard is based on the f ollowing documents: FDIS Report on voting 104/655/FDIS 104/656/RVD Full inf ormation on the voting f or the approval of this standard can be f ound in the report on voting ind
41、icated in the above table. This publication has been draf ted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 60068 series, published under the general title Environmental testing, can be f ound on the IEC website. The committee has decided that the contents of this
42、 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 specif ic publication. At this date, the publication will be reconf irmed, withdrawn, replaced by a revised edition, or amended. International Electrotechn

44、erials, particularly contacts and connections, considered separately, integrated into a subassembly or assembled as a complete equipment. It provides test methods giving inf ormation, on a comparative basis, to aid the selection of materials, choice of production processes and component design, with
45、 regard to corrosion resistance. A guide to the selection of methods and test duration is provided in Annex C. 2 Normative ref erences The f ollowing documents, in whole or in part, are normatively ref erenced in this document and are indispensable f or its application. For dated ref erences, only t
46、he edition cited applies. For undated ref erences, the latest edition of the ref erenced document (including any amendments) applies.
