34、014 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ FIRE HAZARD TESTING Part 1-11: Guidance for assessing the fire hazard of electrotechnical products Fire hazard assessment FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all nat

35、ional 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, Technic

36、al 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.

37、International, 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) Th

38、e 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 recommendati

39、ons 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 u

40、ser. 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 publicatio

41、n 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

42、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, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any persona

43、l 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 refere

44、nces 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 i

45、dentifying any or all such patent rights. International Standard IEC 60695-1-11 has been prepared by IEC technical committee 89: Fire hazard testing. This second edition cancels and replaces the first edition of IEC 60695-1-11 published in 2010, and constitutes a technical revision. The main changes

46、 with respect to the previous edition are: a) Updated references; b) Updated terms and definitions; and c) Added Figure 5 Description of range of products and circumstances of use; and d) Updated Bibliography. BS EN 60695-1-11:2015IEC 60695-1-11:2014 IEC 2014 5 The text of this standard is based on

47、the following documents: FDIS Report on voting 89/1220/FDIS 89/1239/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. It has the

48、status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51 101. This standard is to be used in conjunction with IEC 60695-1-10. 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. Part 1 consis
