30、CTROTECHNICAL COMMISSION _ FIRE HAZARD TESTING Part 1-12: Guidance for assessing the fire hazard of electrotechnical products Fire safety engineering FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnic
31、al 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 Specifications, T
32、echnical 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, gover
33、nmental 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 decisions
34、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 internation
35、al 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 order to
36、 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 clearly
37、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 bodie
38、s. 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, property
39、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 this
40、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 any or a
41、ll such patent rights. International Standard IEC 60695-1-12 Ed 1.0 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. The text of this standard is based on the following documen
42、ts: FDIS Report on voting 89/1237A/FDIS 89/1242/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. IEC 60695-1-12:2015 IEC 2015 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
43、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. IEC 60695-1 consists of the following parts: Part 1-10: Guidance for assessing the fire hazard of electrotechnical products General guidelines Part 1-11: Guidance for assessing
44、 the fire hazard of electrotechnical products Fire hazard assessment Part 1-12: Guidance for assessing the fire hazard of electrotechnical products Fire safety engineering Part 1-30: Guidance for assessing the fire hazard of electrotechnical products Preselection testing process General guidelines P
45、art 1-40: Guidance for assessing the fire hazard of electrotechnical products Insulating liquids. This standard is to be used in conjunction with IEC 60695-1-10 and IEC 60695-1-11. The committee has decided that the contents of this publication will remain unchanged until the stability date indicate
46、d 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 reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 IEC 60695-1-12:2015 IEC 2015 INTRODUCTION Fire safety engineering Fire safety engineering co
47、ncerns the application of engineering methods based on scientific principles to the development or assessment of designs in the built environment through the analysis of specific fire scenarios or through the quantification of risk for a group of fire scenarios. This is in order to achieve fire safe
48、ty engineering objectives, which typically are: a) to protect life safety, b) to protect property, c) to maintain the continuity of operations, d) to protect the natural environment, and e) to preserve heritage. The analysis is based on calculations that use input data obtained principally from quan
49、titative fire tests. Fire safety engineering (FSE) is a discipline increasingly being used in support of performance-based national fire safety regulations in many countries and regional jurisdictions throughout the world. The eight parts of ISO/TR 13387 (see Clause 2 and 1 to 6) and ISO 23932 outline the fundamental methodologies and uses of FSE. Further detailed aspects of FSE are covered
