23、ganization for standardization 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 activitie
24、s, IEC publishes International 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 deal
25、t with may participate 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
26、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 opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
27、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 ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they a
28、re used or for any 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
29、the corresponding 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 respons
30、ible 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 attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical commi
31、ttees 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 fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publicatio
32、ns. 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 publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of paten
33、t rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60695-10-3 has been prepared by IEC technical committee 89: Fire hazard testing. The text of this standard is based on the following documents: FDIS Report on voting 89/1328/FDIS 89/
34、1337/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. BS EN 60695-10-3:2016 4 IEC 60695-10-3:2016 IEC 2016 It has the status of
35、a basic safety publication in accordance 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 pr
36、evious edition: a) Updated references; b) 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
37、 hazard testing, consists of the following 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
38、 “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. BS EN 60695-10-3:2016IEC 60695-10-3:2016 IEC 2016 5 INTRODUCTION In the design of any electrotechnical product, the risk
39、of abnormal heat and the potential hazards associated with abnormal 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, reaso
40、nable foreseeable abnormal use, malfunction and/or failure. The 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 11and IEC 60695-1-11 2 are to provide guidance on how: a) to preven
41、t ignition caused by an electrically energized component part, 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
42、 products enclosure and the minimization of the harmful effects 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
43、fire hazard assessment. This part of IEC 60695 describes a test 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 allowabl
44、e operating temperature. The test method is intended to be used 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 assemb
45、lies under actual abnormal conditions. However, results of this 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 purpo
46、rt to address all of the safety problems associated with its 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

BS EN 60695-10-3:2016 6 IEC 60695-10-3:2016 IEC 2016 FIRE HAZARD TESTING Part 10-3: Abnormal heat Mould stress relief distortion test 1 Scope This part of IEC 60695 specifies a mould stress relief distortion test. It is applicable to electrotechnical equipment including parts made from polymeric m
48、aterials. This test method is intended to evaluate the effects caused by relief of the residual process-induced stress, set in a moulded polymeric assembly of an end product. This stress relief occurs when the sample (energized or not), is exposed to conditioning at a defined temperature for a defin
49、ed period of time. The test specimen is considered to have satisfactorily withstood the test if, after conditioning to room temperature, it meets defined test criteria. This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. It is not intended for use by manufacturers or certification bodies. One of the responsibilities of a tec
