26、_ ELECTRIC CABLES HALOGEN-FREE, LOW SMOKE, THERMOPLASTIC INSULATED AND SHEATHED CABLES OF RATED VOLTAGES UP TO AND INCLUDING 450/750 V Part 3: Flexible cables (cords) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all nation
27、al 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 and in addition to other activities, IEC publishes International Standards, Technical
28、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 Committee interested in the subject dealt with may participate in this preparatory work. Int
29、ernational, 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 accordance with conditions determined by agreement between the two organizations. 2) The
30、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 interested IEC National Committees. 3) IEC Publications have the form of recommendation
31、s 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 responsible for the way in which they are used or for any misinterpretation by any end use
32、r. 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 divergence between any IEC Publication and the corresponding national or regional publication
33、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 marks of conformity. IEC is not responsible for any services carried out by independent ce
34、rtification 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 experts and members of its technical committees and IEC National Committees for any personal
35、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 Publication or any other IEC Publications. 8) Attention is drawn to the Normative referenc
36、es 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 Publication may be the subject of patent rights. IEC shall not be held responsible for ide
37、ntifying any or all such patent rights. International Standard IEC 62821-3 has been prepared by IEC technical committee 20: Electric cables. The text of this standard is based on the following documents: FDIS Report on voting 20/1552A/FDIS 20/1565/RVD Full information on the voting for the approval
38、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 part of IEC 62821 should be read in conjunction with IEC 62821-1, which specifies general requirements. 4 IEC 62821-3:2015 IEC
39、 2015 A list of all parts in the IEC 62821 series, published under the general title, Electric cables Halogen-free, low smoke, thermoplastic insulated and sheathed cables of rated voltages up to and including 450/750 V, can be found on the IEC website. The committee has decided that the contents of
40、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 revised edition, or amended. IEC 62821-3:2015 IEC 2
41、015 5 ELECTRIC CABLES HALOGEN-FREE, LOW SMOKE, THERMOPLASTIC INSULATED AND SHEATHED CABLES OF RATED VOLTAGES UP TO AND INCLUDING 450/750 V Part 3: Flexible cables (cords) 1 Scope This part of IEC 62821 applies to flexible cables for connection to appliances, insulated and sheathed with halogen-free
42、thermoplastic compound and having low emission of smoke and corrosive gases when exposed to fire. NOTE For some types of flexible cables, the term “cord“ is used. Low emission of smoke is checked in accordance with IEC 61034-2. Low emission of corrosive gases is checked as part of the check for abse
43、nce of halogens (see Annex B of IEC 62821-1:2015). The cables are of rated voltages U 0 /U up to and including 300/500 V. Circular cables and flat cables are included. The maximum conductor operating temperature for each of the cables in this standard is 70 C. IEC 62440 should be used as guidance on
44、 the safe use of cables in this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of th
