27、echnical 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 Specificati
28、ons, 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 participate in this preparatory work. International,
29、 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 between the two organizations. 2) The formal decis
30、ions 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 intern
31、ational 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 ord
32、er 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 national or regional publication shall be cle
33、arly 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
34、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 National Committees for any personal injury, prop
35、erty 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
36、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 shall not be held responsible for identifying any
37、 or all such patent rights. International Standard IEC 60695-10-2 has been prepared by IEC technical committee 89: Fire hazard testing. This third edition cancels and replaces the second edition of IEC 60695-10-2 published in 2003. It constitutes a technical revision. It has the status of a basic sa
38、fety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51. The main changes with respect to the previous edition are listed below: The addition of an introduction introduces the user to the basic guidance documents published by TC 89 Addition of a reference to IEC Guide 104 and ISO/IEC
39、Guide 51 in the Scope Additional relevant Terms and Definitions in new Clause 3 4 60695-10-2 IEC:2014 5.2: Additional requirements to the test specimen support at the suggestion of IECEE-CTL to improve reproducibility 5.3: Clarification of heating oven requirements at the suggestion of IECEE-CTL to
40、improve reproducibility 5.4: Specification of minimum resolution consistent with method requirements for optical measurement instrument New Test Procedure in in Clauses 6 and 8 which introduces separate methods for End Product proof testing (Method A) and material performance testing (Method B) Upda
41、ted Clause 11 Test Report to be consistent with other IEC 60695 documents. The text of this standard is based on the following documents: FDIS Report on voting 89/1203/FDIS 89/1210/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in
42、the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 60695 series, under the general title Fire hazard testing, can be found on the IEC web site. The committee has decided that the contents of this publication will r
43、emain unchanged until the stability date indicated 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. IMPORTANT The colour inside logo on the cover
44、 page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 60695-10-2 IEC:2014 5 INTRODUCTION In the design of any electrotechnical product, the risk
45、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
46、nable foreseeable abnormal use, malfunction and/or failure. IEC/TC 89 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 and IEC 60695-1-11 are to provide guidance on how: a) to prevent
47、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 p
48、roducts 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 fi
49、re hazard assessment. This part of IEC 60695 describes a test method where the softening and accelerated material flow under load of a polymeric material is evaluated using a weighted ball-bearing in a heating oven. It should be used to measure, describe, and rank a property of a material in response to elevated temperatures under controlled laboratory conditions. This may be useful for the evaluation of mat
