28、CHNICAL COMMISSION _ FIRE HAZARD TESTING Part 2-12: Glowing/hot-wire based test methods Glow-wire flammability index (GWFI) test method for materials FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnic

29、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

30、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

31、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 o

32、r 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 internationa

33、l 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

34、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 i

35、ndicated 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 bodies

36、. 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 d

37、amage 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 p

38、ublication. 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 al

39、l such patent rights. This Consolidated version of IEC 60695-2-12 bears the edition number 2.1. It consists of the second edition (2010-10) documents 89/1017/FDIS and 89/1034/RVD and its amendment 1 (2014-02) documents 89/1198/FDIS and 89/1207/RVD. The technical content is identical to the base edit

40、ion and its amendment. In this Redline version, a vertical line in the margin shows where the technical content is modified by amendment 1. Additions and deletions are displayed in red, with deletions being struck through. A separate Final version with all changes accepted is available in this publi

This publication has been prepared for user convenience. 4 IEC 60695-2-12:2010 +AMD1:2014 CSV IEC 2014 International Standard IEC 60695-2-12 has been prepared by technical committee 89: Fire hazard testing. It has the status of a basic safety publication in accordance with IEC Guide 104 and

42、ISO/IEC Guide 51. This standard is to be used in conjunction with IEC 60695-2-10 and IEC 60695-2-13. The main changes with respect to the previous edition are listed below: modified title; addition of an Introduction; clarification of Scope; expansion of Clause 2: Normative references; definitions a

43、dded to Clause 3; revision of Clause 4 to alignment with the IEC 60695-11 series to introduce guidance on test programs for material variations; clarification of Clause 8: Conditioning (now Clause 7); deletion of Clause 9 “Initial measurements”; expansion of Clause 10: Test procedures (now Clause 8)

44、; expansion of Clause 11: Observation and measurement (now Clause 9); clarification of Clause 12: Evaluation of test results (now Clause 10); expansion of Clause 13: Test report (now Clause 11).

49、V IEC 2014 INTRODUCTION In the design of any electrotechnical product, the risk of fire and the potential hazards associated with fire need to be considered. In this respect the objective of component, circuit, and product design, as well as the choice of materials, is to reduce to acceptable levels the potential risks of fire during normal operating conditions, reason
