20、 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 questions concerning standardization in the electrical and electronic fields. To this end
21、 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)”). Their preparation is entrusted to technical committees; any IEC National Commi
22、ttee 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 collaborates closely with the International Organization for Standardization (ISO) in ac
23、cordance 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 on the relevant subjects since each technical committee has representation from all
24、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 that the technical content of IEC Publications is accurate, IEC cannot be held res
25、ponsible 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 the maximum extent possible in their national and regional publications. Any diverge
26、nce 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 bodies provide conformity assessment services and, in some areas, access to IEC mar
27、ks 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 to IEC or its directors, employees, servants or agents including individual expert
28、s 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) and expenses arising out of the publication, use of, or reliance upon, this IEC Pub
29、lication 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. 9) Attention is drawn to the possibility that some of the elements of this IEC Pub
30、lication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60695-4 has been prepared by IEC technical committee 89: Fire hazard testing. The text of this standard is based on the following documents: FDIS
31、Report on voting 89/1098/FDIS 89/1112/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. This fourth edition of IEC 60695-4 cancel
32、s and replaces the third edition issued in 2005. It constitutes a technical revision. 4 60695-4 IEC:2012 This standard has the status of a basic safety 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 terms
33、 and definitions that are not specifically electrotechnical and that are either identical or equivalent to those in ISO 13943:2008 have been deleted. The terms and definitions that are specifically electrotechnical and that are in ISO 13943:2008 have been included for the convenience of the user. So
34、me new terms have been included. 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 following introductory elements represent a series of publications: Part 1: Guidance for assessing the fire hazard of electrotechnical p
35、roducts Part 2: Glowing/hot-wire based test methods Part 4: Terminology concerning fire tests for electrotechnical products Part 5: Corrosion damage effects of fire effluent Part 6: Smoke obscuration Part 7: Toxicity of fire effluent Part 8: Heat release Part 9: Surface spread of flame Part 10: Abno
36、rmal heat Part 11: Test flames 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 publication. At this date, the publication will be reconfirmed
37、, withdrawn, replaced by a revised edition, or amended. 60695-4 IEC:2012 5 FIRE HAZARD TESTING Part 4: Terminology concerning fire tests for electrotechnical products 1 Scope The terms and definitions in this standard are applicable to fire tests for electrotechnical products. This basic safety publ
38、ication is 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. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the prepara
39、tion of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications. 2 Normative references The following documents, in whole or in part, are normatively referenced in thi
40、s document and are indispensable for its application. For dated references, only the edition cited applies.
