28、9-2:2014 IEC:2014 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ FIRE HAZARD TESTING Part 9-2: Surface spread of flame Summary and relevance of test methods FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrot
29、echnical 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, Technical Specificati
30、ons, 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. International,
31、 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 formal deci
32、sions 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 recommendations for inter
33、national 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 user. 4) In or
34、der 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 shall be cl
35、early 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 certification
36、 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 injury, pro
37、perty 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 references cited in
38、 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 identifying an
39、y or all such patent rights. International Standard IEC 60695-9-2 has been prepared by IEC technical committee 89: Fire hazard testing. It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51. This first edition cancels and replaces the second edition of
40、 IEC TS 60695-9-2 published in 2005. This edition constitutes a technical revision. The text of this standard is based on the following documents: FDIS Report on voting 89/1202/FDIS 89/1209/RVD Full information on the voting for the approval of this standard can be found in the report on voting indi
41、cated in the above table. 4 IEC 60695-9-2:2014 IEC:2014 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the 60695 series, under the general title Fire hazard testing, can be found on the IEC web site. This International standard is to b
42、e used in conjunction with IEC 60695-9-1. 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.iec.ch“ in the data related to the specific publication. At this date, the publication will be
43、reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 60695-9-2:2014 IEC:2014 5 INTRODUCTION The risk of fire needs to be considered in any electrical circuit. The objective of component, circuit and equipment design, as well as the choice of materials, is to reduce the likelihood o
44、f fire, even in the event of foreseeable abnormal use, malfunction or failure. Electrotechnical products, primarily as victims of fire, may nevertheless contribute to the fire. Fire hazard increases as the burning area increases, leading in some cases to flashover and a fully developed fire. This is
45、 a typical fire scenario in buildings. It is therefore useful to measure the rate and extent of the surface spread of flame. This part of IEC 60695-9 describes surface spread of flame test methods in common use to assess electrotechnical products or materials used in electrotechnical products. It fo
46、rms part of the IEC 60695-9 series which gives guidance to product committees wishing to incorporate test methods for surface spread of flame in product standards. IEC 60695-9 consists of the following parts: Part 9-1: Surface spread of flame General guidance Part 9-2: Surface spread of flame Summar
47、y and relevance of test methods. 6 IEC 60695-9-2:2014 IEC:2014 FIRE HAZARD TESTING Part 9-2: Surface spread of flame Summary and relevance of test methods 1 Scope This part of IEC 60695 presents a summary of published test methods that are used to determine the surface spread of flame of electrotech
48、nical products or materials from which they are formed. It represents the current state of the art of the test methods and, where available, includes special observations on their relevance and use. The list of test methods is not to be considered exhaustive, and test methods that were not developed
49、 by IEC TC89 are not to be considered as endorsed by IEC TC89 unless this is specifically stated. This summary cannot be used in place of published standards which are the only valid reference documents. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC G
