24、 apparatus and common test procedure FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questi
25、ons concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s
26、)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC colla
27、borates closely with the International Organization for Standardization (ISO) in accordance with conditions determined 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 o
28、n the relevant subjects since each technical committee has representation from all interested IEC National Committees. 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
29、 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 promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to t
30、he 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 indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification
31、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. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach
32、 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 damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees)
33、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 publication. Use of the referenced publications is indispensable for the correct application of this publication.
34、 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 all such patent rights. International Standard IEC 60695-2-10 has been prepared by IEC technical committee 89: Fir
35、e hazard testing. This second edition of IEC 60695-2-10 cancels and replaces the first edition of IEC 60695-2-10 published in 2000. This edition constitutes a technical revision. It has the status of a basic safety publication in accordance with IEC Guide 104:2010 and ISO/IEC Guide 51:1999. This sta
36、ndard is to be used in conjunction with IEC 60695-2-11, IEC 60695-2-12, and IEC 60695-2-13. The main changes with respect to the previous edition are listed below. The rationale can be found in 89/960A/CC, 89/944A/CC, and 89/1030/CC. 4 60695-2-10 IEC:2013 A table of contents has been added. The intr
37、oduction has been updated to align with other TC89 documents. The scope has been clarified to align with other documents in the IEC 60695-2 Glow-wire series. Terms and definitions relevant to this document have been added. Clause 4 has been deleted and the remaining clauses renumbered. The descripti
38、on of the power supply has been updated with additional details (see 4.1). The temperature measuring system (see 4.3) and the description of the specified layer has been updated (see 4.4). New guidance has been introduced to assist in the verification of the temperature measuring system (see 5.2 and
39、 Annex C). The common test produced has been clarified (see Clause 7). The tolerances have been changed for the dimensions of the glow-wire (see Figure 1). New guidance on flaming observations has been added (see Annex B). The text of this standard is based on the following documents: FDIS Report on
40、 voting 89/1154/FDIS 89/1163/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. A list of all parts in the IEC 60695 series, publi
41、shed under the general title Fire hazard testing, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publicatio
42、n. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users
43、 should therefore print this document using a colour printer. 60695-2-10 IEC:2013 5 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 desi
44、gn, as well as the choice of materials, is to reduce to acceptable levels the potential risks of fire during normal operating conditions, reasonable foreseeable abnormal use, malfunction, and/or failure. IEC 60695-1-10 was developed, together with its companion, IEC 60695-1-11, to provide guidance o
45、n 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 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 i
46、n the event of ignition. Secondary aims of these documents include the minimization of any flame spread beyond the products enclosure and the minimization of harmful effects of fire effluents such as heat, smoke, toxicity and/or corrosivity. Fires involving electrotechnical products can also be init
47、iated from external non-electrical sources. Considerations of this nature should be dealt with in the overall fire risk assessment. In electrotechnical equipment, overheated metal parts can act as ignition sources. In glow- wire tests, a glowing wire is used to simulate such an ignition source. This
48、 part of IEC 60695 gives recommendations with regard to the glow-wire test apparatus and describes a common test procedure for tests applicable to end products and materials to be used with IEC 60695-2-11 which describes a glow-wire flammability test for end products (GWEPT), IEC 60695-2-12 which de
49、scribes a glow-wire flammability index test for materials (GWFI), and IEC 60695-2-13 which describes a glow-wire ignition temperature test method for materials (GWIT). 6 60695-2-10 IEC:2013 FIRE HAZARD TESTING Part 2-10: Glowing/hot-wire based test methods Glow-wire apparatus and common test procedure 1 Scope This part of IEC 60695 specifies the glow-wire apparatus and common test procedure to
