18、nical 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 thi
19、s 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)”). Their preparation is entrusted to technical committees; any IEC National
20、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 collaborates closely with the International Organization for Standardization (ISO)
21、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 on the relevant subjects since each technical committee has representation from
22、 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 that the technical content of IEC Publications is accurate, IEC cannot be hel
23、d 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 the maximum extent possible in their national and regional publications. Any di
24、vergence 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 IE
25、C 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 to IEC or its directors, employees, servants or agents including individual e
26、xperts 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 IE
27、C 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. 9) Attention is drawn to the possibility that some of the elements of this IE

40、rds associated with fire need to be considered. In this respect the objective of component, circuit and product equipment design, as well as the choice of materials, is to reduce to acceptable levels the potential risks of fire to a tolerable level even in the event of reasonably foreseeable abnorma
41、l (mis)use, malfunction or failure. This standard, together with its companions, IEC 60695-1-11 and IEC 60695-1-12, provides guidance on how this is to be accomplished. The use of compartments with fire-resistant boundaries, and the use of detection and suppression systems are important methods for
42、the mitigation of fire risk, but are not dealt with in this standard. Fires involving electrotechnical products can be initiated from external non-electrical sources. Considerations of this nature are dealt with in an overall fire hazard assessment. The aim of the IEC 60695 series of standards is to
43、 save lives and property by reducing the number of fires or reducing the consequences of the fire. This can be accomplished by: the primary aims are trying to prevent ignition caused by an electrically energised component part and, in the event of ignition, to confine any resulting fire within the b
44、ounds of the enclosure of the electrotechnical product; secondary aims include trying to minimise any flame spread beyond the products enclosure and to minimise the harmful effects of fire effluents including heat, smoke, and toxic or corrosive combustion products. Fires involving electrotechnical p
45、roducts can also be initiated from external non-electrical sources. Considerations of this nature are dealt with in the overall risk assessment. Assessing the fire hazard of electrotechnical products is accomplished by performing fire hazard tests. These tests are divided into two fundamental groups
46、: qualitative fire tests and quantitative fire tests. Fire testing of electrotechnical products should, whenever possible, be carried out using quantitative fire tests having the following characteristics. a) The test should take into account the circumstances of product use, i.e. contemplated end-u
47、se conditions as well as foreseeable abnormal use. This is because fire conditions that may be hazardous under one set of circumstances will not necessarily pose the same threat under a different set. b) It should be possible to correlate the test results with the harmful effects of fire effluents r
48、eferred to above, i.e. the thermal and airborne threats to people and/or property in the relevant end-use situation. This avoids the creation of artificial, and sometimes distorted, performance scales with no clear relationship to fire safety. c) Recognizing that there are usually multiple contribut
49、ions to the effects of real fires, the test results should be expressed in well-defined terms and using rational scientific units, so that the products contribution to the overall fire effects can be quantitatively assessed and compared with that of other products contributions. Although quantitative tests are preferred, the characteristics of qualitative fire tests are that they provide pass/fail and classification results. Under certain circumstances it will be appropriate to
