30、uidance 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 questions concerning standardizatio
31、n 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)”). Their preparation is ent
32、rusted 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 collaborates closely with the Inter
33、national 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 on the relevant subjects since
34、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 that the technical content of
35、 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 the maximum extent possible in
36、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 bodies provide conformity asse
37、ssment 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 to IEC or its directors, empl
38、oyees, 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) and expenses arising out of th
39、e 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. 9) Attention is drawn to the
40、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 60695-7-1 has been prepared by IEC technical committee 89: Fire hazard testing. This third ed
41、ition cancels and replaces the second edition published in 2004. It constitutes a technical revision. The main changes with respect to the previous edition are listed below: minor editorial and technical changes throughout; Introduction text referring to IEC 60695-7-50 and ISO/TS 19700 has been upda
42、ted; references to the ISO 9122 series have been deleted (other than an historical reference to ISO 9122-1 in the Introduction) and the text throughout has been updated; definitions have been updated in accordance with ISO/IEC 13943:2008; BS EN 60695-7-1:2010 4 60695-7-1 IEC:2010 dispersal volume is
43、 stated to be an important parameter in the assessment of toxic hazard; Table 2 has been updated; Figures 1 and 2 have both been updated. It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC Guide 51. The text of this standard is based on the following documen
44、ts: FDIS Report on voting 89/990/FDIS 89/1003/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 standard is to be used in co
45、njunction with IEC 60695-7-2. A list of all the parts of IEC 60695 series, under the general title of Fire hazard testing, can be found on the IEC website. Part 7 consists of the following parts: Part 7-1: Toxicity of fire effluent General guidance Part 7-2: Toxicity of fire effluent Summary and rel
46、evance of test methods Part 7-3: Toxicity of fire effluent Use and interpretation of test results Part 7-50: Toxicity of fire effluent Estimation of toxic potency Apparatus and test method Part 7-51: Toxicity of fire effluent Estimation of toxic potency Calculation and interpretation of test results
47、 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; withdrawn; replaced by a rev
48、ised edition, or amended. BS EN 60695-7-1:201060695-7-1 IEC:2010 5 INTRODUCTION Electrotechnical products sometimes become involved in fires. However, except for certain specific cases (for example, power generating stations, mass transit tunnels, computer suites), electrotechnical products are not
49、normally present in sufficient quantities to form the major source of toxic hazard. For example, in domestic dwellings and places of public assembly, electrotechnical products are usually a very minor source of fire effluent compared with, for example, furnishings. The IEC 60695-7 series of publications is subject to the ongoing evolution of fire safety philosophy within ISO TC 92. The guidance in this International Standard is consistent with the principl
