36、OMMISSION _ ENVIRONMENTAL TESTING Part 2-52: Tests Test Kb: Salt mist, cyclic (sodium chloride solution) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The
37、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 Specifications, Technical Reports, Publicly Available Specific
38、ations (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. International, governmental and non-governmental organizations li
39、aising 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 decisions or agreements of IEC on technical matters expr
40、ess, 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 international use and are accepted by IEC National Commit
41、tees 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 order to promote international uniformity, IEC Nationa
42、l 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 clearly indicated in the latter. 5) IEC itself does no
43、t 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 certification bodies. 6) All users should ensure that they have t
44、he 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, property damage or other damage of any nature whatsoeve
45、r, 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 in this publication. Use of the referenced publication
46、s 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 any or all such patent rights. International Standard
47、IEC 60068-2-52 has been prepared by IEC technical committee 104: Environmental conditions, classification and methods of test. This third edition cancels and replaces the second edition published in 1996. This edition constitutes a technical revision. This edition includes the following significant
48、technical changes with respect to the previous edition: a) the entire content has been harmonized with ISO 9227 as far as possible; b) an introduction has been added; c) the scope has been simplified; d) normative references have been updated; e) the general description of the test has been changed;
49、 BS EN IEC 60068252:2018IEC 60068-2-52:2017 IEC 2017 5 f) a dry chamber has been added to the test apparatus; g) severities have been changed to test methods; h) test methods 7 and 8 have been added; i) information on the test report has been added; j) Figure 1 has been changed to Table 1; k) a typical test apparatus example has been added in a new Annex A; l) a description of each test method has been added in a new Annex B; m) bibliographical references have been added.
