    25、OMFORT HEATING AND PREVENTION OF ICE FORMATION 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

    26、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 (PAS) and Guides (hereafter referred to as “IEC Pub

    27、lication(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 with the IEC also participate in this preparation.

    28、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, as nearly as possible, an international consensus of

    29、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 in that sense. While all reasonable efforts are made

    30、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 Committees undertake to apply IEC Publications transpare

    31、ntly 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 provides no marking procedure to indicate its approval and cannot be ren

    32、dered responsible for any equipment declared to be in conformity with an IEC Publication. 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

    33、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 Publication or any o

    34、ther 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 Publication may be t

    35、he subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60800 has been prepared by IEC technical committee 20: Electric cables. This third edition cancels and replaces the second edition, published in 1992, and constitu

    36、tes a technical revision. The significant technical changes with respect to the previous edition are as follows: introduction of heating cable sets; testing of heating cable sets, including the integrated cold-lead, cold-lead splice and end-termination in twin and multicore cable sets, in addition t

    37、o the heating cable; introduction of requirements for installation instructions; reduction to two, instead of three, mechanical classes, one for cables intended for installation with a low risk of mechanical damage (M1) and one for cables intended for installation with a higher risk of mechanical da

    38、mage (M2); elimination of reference to specific materials to be used as insulation and sheath; introduction of routine and sample tests. 660800 IEC:2009 5 The text of this standard is based on the following documents: FDIS Report on voting 20/1057/FDIS 20/1066/RVD Full information on the voting for

    39、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. The committee has decided that the contents of this publication will remain unchanged until the maintenance result dat

    40、e 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. 6 60800 IEC:2009 INTRODUCTION This International Standard is intended to provide a c

    41、omprehensive overview of the essential requirements and testing appropriate to electrical resistance heating cables used for comfort heating and prevention of ice formation. While some of this work already exists in national standards or international standards, this standard has collated much of th

    42、is existing work. This standard provides a means to verify the electrical, thermal and mechanical durability of resistive heating cables, so that in normal use their performance is without danger to the user or surroundings. Compliance is checked by carrying out all the tests specified in this stand

    43、ard. 660800 IEC:2009 7 HEATING CABLES WITH A RATED VOLTAGE OF 300/500 V FOR COMFORT HEATING AND PREVENTION OF ICE FORMATION 1 Scope and object This International Standard is applicable to, and specifies requirements for, resistive heating cables for low temperature applications such as comfort heati

    44、ng and the prevention of ice formation. These cables and cable sets may comprise either factory fabricated or field (work-site) assembled units, and which are heating cables assembled in accordance with manufacturers instructions. Bare conductors and protected conductors to be supplied at voltages e

    45、qual to, or less than, 50 V are excluded from the scope of this standard. NOTE Terminations and gland fittings are outside the scope of this standard. Typical applications include, but are not limited to: surface heating installed in or under surfaces; direct and storage heating; snow melting and fr

    46、ost protection of roofs, gutters, pipes, etc. Heating cables for industrial and commercial applications are specified in the IEC 62395 series 11as are mineral insulated heating cables. Applications in which the operating sheath temperature exceeds 100 C are outside the scope of this standard. The ob

    47、ject of this standard is to ensure that electrical resistance heating cables operate safely under their normal defined conditions of use. This is achieved by: employing heating cables of the appropriate construction that meet the test criteria detailed in this standard; including, for cables with an

    48、 electrical protective component, a metallic braid, concentric wires or sheath, or other suitable electrically conductive material for protective purposes in case of fault; ensuring that the cables operate at safe temperatures with respect to the materials used in the construction of the cables and

    49、their installations according to national regulations. 2 Normative references The following referenced documents are indispensable for the application of this document.
