25、dardization comprising all national 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 In
26、ternational Standards, Technical 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 particip
27、ate in this preparatory work. 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 betwe
28、en the two organizations. 2) The 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 Publication
29、s 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 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
30、 misinterpretation by any end user. 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
31、national or regional publication 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 servi
32、ces carried out by independent 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 Nati
33、onal Committees for any personal 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 i
34、s drawn to the Normative references 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 shal

The text of this standard is based on the following documents: FDIS Report on voting 89/1328/FDIS 89/1337/RVD Full info
36、rmation 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. 4 IEC 60695-10-3:2016 IEC 2016 It has the status of a basic safety publication in accordance
37、 with IEC Guide 104 and ISO/IEC Guide 51. This second edition of IEC 60695-10-3 cancels and replaces the first edition issued in 2002. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Updated references; b
38、) Updated equipment; c) Added terms and definitions; and d) Added Bibliography. 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. The IEC 60695-10 series, under the general title Fire hazard testing, consists of the followi
39、ng parts: Part 10-2: Abnormal heat Ball pressure test Part 10-3: Abnormal heat Mould stress relief distortion test The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data rel
40、ated to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 60695-10-3:2016 IEC 2016 5 INTRODUCTION In the design of any electrotechnical product, the risk of abnormal heat and the potential hazards associated with ab
41、normal heat 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 during normal operating conditions, reasonable foreseeable abnormal use, malfunction and/or failure. T
42、he IEC has developed IEC 60695-1-10, together with its companion, IEC 60695-1-11, to provide guidance on how this is to be accomplished. The primary aims of IEC 60695-1-10 1 1and IEC 60695-1-11 2 are to provide guidance on how: a) to prevent ignition caused by an electrically energized component par
43、t, and b) to confine any resulting fire within the bounds of the enclosure of the electrotechnical product in the event of ignition. Secondary aims of IEC 60695-1-10 and IEC 60695-1-11 include the minimization of any flame spread beyond the products enclosure and the minimization of the harmful effe
44、cts of fire effluents such as heat, smoke, toxicity and/or corrosivity. Fires involving electrotechnical products can also be initiated from external non-electrical sources. Considerations of this nature should be dealt with in the overall fire hazard assessment. This part of IEC 60695 describes a t
45、est method that simulates the effects caused by relief of the residual process-induced stress, frozen in a moulded polymeric assembly of an end product, when the end product or a part of it is exposed to conditioning at the maximum allowable operating temperature. The test method is intended to be u
46、sed to evaluate whether the product after conditioning continues to meet the requirements of the relevant product specification. It is not be used to solely describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual abnormal conditions. However, results of t
47、his test may be used as elements of a fire hazard assessment which takes into account all of the factors pertinent to a particular end use. This part of IEC 60695 may involve hazardous materials, operations, and equipment. It does not purport to address all of the safety problems associated with its
48、 use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. _ 1Numbers in square brackets refer to the bibliography. 6 IEC 60695-10-3:2016 IEC 2016 FIRE HAZARD TESTING Part 10
