21、 cables 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
22、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
23、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
24、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
25、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
26、 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
27、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
28、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
29、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
30、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
31、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. This consolidated version of IEC 61156-7 consists of the first edition (2003) documents 46C/573/FDIS and 46C/591/RVD and
32、 its amendment 1 (2012) documents 46C/956/CDV and 46C/965/RVC. It bears the edition number 1.1. The technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. A vertical line in the margin shows where the base publication has been modif
33、ied by amendment 1. Additions and deletions are displayed in red, with deletions being struck through. 61156-7 IEC:2003+A1:2012 3 International Standard IEC 61156-7 has been prepared by subcommittee 46C: Wires and symmetric cables, of IEC technical committee 46: Cables, wires, waveguides, r.f. conne
34、ctors, r.f. and microwave passive components and accessories. The bilingual version (2003-11) replaces the English version including its Corrigendum 1 (2003-09). The French version has not been voted upon. This standard is to be read in conjunction with IEC 61156-1. This publication has been drafted
35、 in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of the base publication and its amendments 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 th
36、is date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The “colour inside” logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users shoul

38、ables 1 General 1.1 Scope This sectional specification relates to IEC 61156-1. The cables described herein may be used for various communication systems as well as for analog systems, such as video, that exist or are under development and which may use as many as four pairs simultaneously. In this s
39、ense, this sectional specification provides the cable characteristics required by system developers to evaluate new systems as well as to enhance present systems. It covers a cable having four individually screened (STP) pairs. The cable may be provided with a common screen over the cable core. The
40、transmission characteristics are specified up to a frequency of 1 200 MHz and at a temperature of 20 C. The cables covered by this sectional specification are intended to operate with voltages and currents normally encountered in communication systems. These cables are not intended to be used in con
41、junction with low impedance sources, for example, the electric power supply of public utility mains. 1.2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the l
42、atest edition of the referenced document (including any amendments) applies.

45、nditions Under static conditions, the cables shall operate in the temperature range from 20 C to +60 C. The temperature dependence of the cables is specified for screened cables and should be taken into account for the design of actual cabling systems. The recommended temperature range during instal
46、lation should be indicated in the relevant detail specification. 2 Definitions, materials and cable construction 2.1 Definitions See 2.1 of IEC 61156-1. 2.2 Materials and cable construction 2.2.1 General remarks The choice of materials and cable construction shall be suitable for the intended applic
47、ation and installation of the cable. Particular care shall be taken to meet any special requirements for fire performance (such as burning properties, smoke generation, evolution of halogen gas, etc.). A detail specification may be prepared. 2.2.2 Cable construction The cable construction shall be i
48、n accordance with the materials, dimensions and assembly details given in the relevant detail specification. 2.2.3 Conductor The conductor shall be a solid annealed copper conductor, in accordance with 2.2.3 of IEC 61156-1, and shall have a diameter between 0,5 mm and 0,8 mm. 2.2.4 Insulation The co
49、nductor shall be insulated with a suitable thermoplastic material. Examples of suitable materials are: polyolefin; fluoropolymer; low-smoke zero-halogen thermoplastic material. The insulation may be solid or cellular with or without a solid dielectric skin. The insulation shall be continuous and shall have a thickness such that the completed cable meets the specified requirements. The nominal
