35、uent Summary and relevance of test methods 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
36、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 Specifications (PAS) and Guides (hereafter referred to as “IEC Publica
37、tion(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 liaising with the IEC also participate in this preparation. IEC
38、 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 express, as nearly as possible, an international consensus of opi
39、nion 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 Committees in that sense. While all reasonable efforts are made to
40、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 National Committees undertake to apply IEC Publications transparentl
41、y 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 not provide any attestation of conformity. Independent certific
42、ation 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 have the latest edition of this publication. 7) No liability shall
43、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 whatsoever, whether direct or indirect, or for costs (including legal
44、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 publications is indispensable for the correct application of this public
45、ation. 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 Standard IEC 60695-7-2 has been prepared by IEC technical committee 89
46、: Fire hazard testing. This first edition of IEC 60695-7-2 cancels and replaces the first edition of Technical Report IEC/TR 60695-7-2 published in 2002. It constitutes a technical revision and now has the status of an International Standard. It has the status of a basic safety publication in accord
47、ance with IEC Guide 104 and ISO/IEC Guide 51. The main changes with respect to the previous edition are listed below: editorial changes throughout; expanded normative references; revised terms and definitions; 6 60695-7-2 IEC:2011 modifications to “Repeatability and reproducibility” data throughout;
48、 modifications to “Relevance of test data” throughout; modifications to Clause 5; new Table 1 and Figure 1; introduction of ISO test method in new Subclause 6.6; introduction of test method from EN 50305 in new Subclause 6.8; revised Annex A and new Table A.1; expanded Bibliography. The text of this
49、 standard is based on the following documents: FDIS Report on voting 89/1059/FDIS 89/1073/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. A list of all the parts in the 60695 series, under the general title Fire hazard te
