31、IMATIC TEST METHODS Part 31: Flammability of plastic-encapsulated devices(internally induced)FOREWORD1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the

32、IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committe

33、e interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accor

34、dance with conditions determined by agreement between thetwo organizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all int

35、erested National Committees.3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4) In order to promote internati

36、onal unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the l

37、atter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof pa

38、tent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60749-31 has been prepared by IEC technical committee 47:Semiconductor devices.The text of this test method is reproduced from IEC 60749 Ed.2, chapter 4, clause 1.1 withoutchan

39、ge. It has therefore not been submitted to vote a second time and is still based on thefollowing documents:FDIS Report on voting47/1394/FDIS 47/1402/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication h

40、as been drafted in accordance with the ISO/IEC Directives, Part 3.Each test method governed by IEC 60749-1 and which is part of the series is a stand-alonedocument, numbered IEC 60749-2, IEC 60749-3, etc. The numbering of these test methods issequential, and there is no relationship between the numb

41、er and the test method (i.e. nogrouping of test methods). The list of these tests will be available in the IEC Internet site andin the catalogue. 4 60749-31 CEI:2002La mise jour de toute mthode dessais individuelle est indpendante de toute autre partie.Le comit a dcid que le contenu de cette publica

43、 of any other part.The committee has decided that the contents of this publication will remain unchanged until2007. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended.The contents of the corrigendum of August 2003 have been included in this copy.
