17、2: Test flames 1 kW nominal pre-mixed flame Apparatus, confirmatory test arrangement and guidance FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object
18、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 Specifications, Technical Reports, Publicly Available Specifications
19、(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, governmental and non- governmental organizations liaising
20、 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 decisions or agreements of IEC on technical matters express, a
21、s 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 international use and are accepted by IEC National Committees i
22、n 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 order to promote international uniformity, IEC National Comm
23、ittees 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 clearly indicated in the latter. 5) IEC itself does not prov
24、ide 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 bodies. 6) All users should ensure that they have the lat
25、est 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, property damage or other damage of any nature whatsoever, whe
26、ther 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 this publication. Use of the referenced publications is i
27、ndispensable 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 or all such patent rights. DISCLAIMER This Redline versi

In this respect the objective of component, circuit, and product design, as well as the choice of materi
39、als, is to reduce to acceptable levels the potential risks of fire during normal operating conditions, reasonable foreseeable abnormal use, malfunction, and/or failure. The IEC has developed IEC 60695-1-10 1 1 , together with its companion, IEC 60695-1-11 2, to provide guidance on how this is to be
40、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 in the event of ignit
41、ion. 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 initiated from external
42、non-electrical sources. Considerations of this nature should be dealt with in the overall fire risk assessment. IEC 60695-11-2 provides a description of the apparatus required to produce a 1 kW test flame, and provides a description of the principle of a confirmation procedure to check that the effe
43、ctive power output of the flame is as intended. Guidance on confirmatory tests for test flames is given in IEC TS 60695-11-40 3. This part of IEC 60695 may involve hazardous materials, operations, and equipment. It does not purport to address all of the safety problems associated with its use. It is
44、 the responsibility of the user of this international 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.

45、Part 11-2: Test flames 1 kW nominal pre-mixed flame Apparatus, confirmatory test arrangement and guidance 1 Scope This part of IEC 60695 gives the requirements for the production and confirmation of a nominal 1 kW propane/air pre-mixed test flame for use in fire hazard testing. This basic safety pub
46、lication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 4 and ISO/IEC Guide 51 5. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the pr
47、eparation 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 are referred to in the text in such a way that som
