35、onal 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 Standards, Technica
36、l 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 preparatory work. I
37、nternational, 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
38、 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 form of recommendatio
39、ns 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 misinterpretation by any end us
40、er. 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 regional publication
41、 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 out by independent c
42、ertification 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
43、 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 the Normative referen
44、ces 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 responsible for id
45、entifying any or all such patent rights. International Standard IEC 60695-11-20 has been prepared by IEC technical committee 89: Fire hazard testing. The text of this standard is based on the following documents: FDIS Report on voting 89/1241/FDIS 89/1250/RVD Full information on the voting for the a
46、pproval of this standard can be found in the report on voting indicated in the above table. BS EN 60695-11-20:2015IEC 60695-11-20:2015 IEC 2015 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This second edition cancels and replaces the first edition of IEC 606
47、95-11-20 published in 1999. This edition constitutes a technical revision. The main changes with respect to the first edition are listed below: The Part title has been modified to the singular 500 W flame test method. Editorial changes have been made throughout the document for the purpose of aligni
48、ng IEC 60695-11-10 with IEC 60695-11-20. The Introduction has been modified to clarify the description of the test method. The Scope has been modified for clarification. All occurrences of the term “fixture” have been deleted from the document. Preferred thickness values have been added to 7.2 and 7
49、.3. 7.4.4: Thickness measurement is now numbered 7.5 to which a new Table 1 Thickness tolerances has been added. New Subclause 8.1.4 Conditioning of the cotton pad has been added. 8.2.3 clarifies the application of the test flame to distorted specimens Explanatory notes have been added to Figures 5 and 6. The Bibliography has been updated and references added. It has the status of a basic safety publication in accordance with IEC Guide 104 and
