    29、ance FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization i

    30、n the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrus

    31、ted 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 liaising with the IEC also participate in this preparation. IEC collaborates closely with the Interna

    32、tional 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 express, as nearly as possible, an international consensus of opinion on the relevant subjects since ea

    33、ch 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 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of I

    34、EC 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 National Committees undertake to apply IEC Publications transparently to the maximum extent possible in th

    35、eir 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 not provide any attestation of conformity. Independent certification bodies provide conformity assess

    36、ment 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 the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employ

    37、ees, 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 whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the

    38、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 publications is indispensable for the correct application of this publication. 9) Attention is drawn to the po

    39、ssibility 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 IEC 60695-11-5 has been prepared by IEC technical committee 89: Fire hazard testing. This second ed

    40、ition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The scope has been broadened to allow this test method to also simulate the effect

    41、s of small flames from outside the equipment; b) Propane and butane gas are the specified fuel source with a minimum purity of 95 %; c) A new concept has been added which allows the burner to be moved during the test to avoid dripping material from falling onto the tip of the burner tube; d) The bur

    42、ner tube material is now a referenced source; IEC 60695-11-5:2016 IEC 2016 5 e) The reference for the copper block material has changed the ISO publication (ISO 1337) has been withdrawn with no replacement. A new callout is now used; f) Informative Annex C and a bibliography have been added. The tex

    43、t of this standard is based on the following documents: FDIS Report on voting 89/1346/FDIS 89/1351/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

    44、Directives, Part 2. It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51. A list of all the parts in the IEC 60695 series, under the general title Fire hazard testing, can be found on the IEC website. The committee has decided that the contents of thi

    45、s publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.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. 6 IEC 60695-11-5:2016 IEC

    46、2016 INTRODUCTION The best method for testing electrotechnical products with regard to fire hazard is to duplicate exactly the conditions occurring in practice. In most instances this is not possible. Accordingly, for practical reasons, the testing of electrotechnical products with regard to fire ha

    47、zard is best conducted by simulating as closely as possible the actual effects occurring in practice. Parts of electrotechnical equipment might be exposed to excessive thermal stress due to electric effects. This can result in deterioration that might impair the safety of the equipment. Such parts s

    48、hould not be unduly affected by heat or by fire generated within the equipment. Parts of insulating material or of other combustible material which are liable to propagate flames inside the equipment may be ignited by flames produced by a failing component. Under certain conditions, for example a fa

    49、ult current flowing over a tracking path, overloading of components or parts and bad connections, flames may also occur; such flames may impinge upon combustible parts in the vicinity. This part of IEC 60695 is intended to be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and is not intended
