23、CTROTECHNICAL COMMISSION _ ENVIRONMENTAL TESTING Part 2-60: Tests Test Ke: Flowing mixed gas corrosion test FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). T

24、he 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 Speci

25、fications (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

26、 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 decisions or agreements of IEC on technical matters e

27、xpress, 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 Com

28、mittees 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 Nati

29、onal 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

30、 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 certification bodies. 6) All users should ensure that they hav

31、e 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, property damage or other damage of any nature whatso

32、ever, 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 publicat

33、ions 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 Standa

34、rd IEC 60068-2-60 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 1995, and constitutes a technical revision. This edition includes the following significant techn

35、ical changes with respect to the previous edition: updated IEC format; updated normative references list; addition of information of the working volume; revision of the test procedure; revision of the figures in Annex B. BS EN 60068-2-60:2015 4 IEC 60068-2-60:2015 IEC 2015 The text of this standard

36、is based on the following documents: FDIS Report on voting 104/655/FDIS 104/656/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. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

37、 A list of all parts in the IEC 60068 series, published under the general title Environmental testing, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.i

38、ec.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.

39、e This part of IEC 60068-2 determines the corrosive influence of operating and storage indoor environments on electrotechnical products components, equipment and materials, particularly contacts and connections, considered separately, integrated into a subassembly or assembled as a complete equipmen

40、t. It provides test methods giving information, on a comparative basis, to aid the selection of materials, choice of production processes and component design, with regard to corrosion resistance. A guide to the selection of methods and test duration is provided in Annex C. 2 Normative references Th

41、e following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

43、sulation resistance ISO 431, Copper refinery shapes 3 Test apparatus The test apparatus consists of a climatic system, test enclosure, gas delivery system and means for measuring gas concentration. Details of design and construction are optional but shall be such that the conditions specified for ea

44、ch method are fulfilled throughout the working volume and shall comply with the following requirements: water droplets or aerosols shall not be injected into the test enclosure; air and water used shall be sufficiently clean in order not to affect performance of the test; the test atmosphere shall f

45、low through the enclosure in such a manner as to ensure uniform test conditions within the working volume; the sampling point for gas analysis shall be in the working volume of the test enclosure; the exhaust gases shall be treated in accordance with the relevant regulatory stipulations; the wet bul

46、b pod shall be placed in the test chamber in such a manner not to exceed 0,1 % of the cross-section of the test chamber. BS EN 60068-2-60:2015 6 IEC 60068-2-60:2015 IEC 2015 Because of the strong synergistic effect and the so called “memory effect” (i.e., it is difficult to fully remove the chlorine

47、 compounds from the chamber, tubes, etc.), it is recommended that enclosures and tubing used for tests that incorporate chlorine only be used for chlorine tests. The working volume is the volume within which the individual corrosion (mass increase of copper coupons expressed in mg/( dm2 day) accordi

48、ng to Annex A) at each location differs by a maximum of 15 % from the average corrosion of all coupons within the working volume. 4 Severities The test severity shall be given in the relevant specification. It is defined by the test method, chosen from Table 1, the test duration. Preferred durations

49、, in days, are 4, 7, 10, 14 and 21. Four methods are defined. The different parameters for each method are summarized in the following Table 1. A guidance for the use of each method is given in Clause C.3.
