22、AL ELECTROTECHNICAL COMMISSION _ COAXIAL COMMUNICATION CABLES Part 4: Sectional specification for radiating cables FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committ

23、ees). 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 Specifications, Technical Reports, Publicly Availabl

24、e 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. International, governmental and non- governmental organ

25、izations 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 formal decisions or agreements of IEC on technical m

26、atters 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 recommendations for international use and are accepted by IEC Nati

27、onal 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 user. 4) In order to promote international uniformity,

28、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 shall be clearly indicated in the latter. 5) IEC its

29、elf 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 certification bodies. 6) All users should ensure that

30、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 injury, property damage or other damage of any natur

31、e 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 references cited in this publication. Use of the referenced

32、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 identifying any or all such patent rights. Internationa

33、l Standard IEC 61196-4 has been prepared by subcommittee 46A: Coaxial cables, of IEC technical committee 46: Cables, wires, waveguides, R.F. connectors, R.F. and microwave passive components and accessories. This third edition cancels and replaces the second edition published in 2004. This edition c

34、onstitutes a technical revision. The main changes with respect to the previous edition are as follows: a definition for coupling loss was added, Clause 4 “Materials and cable construction“ was added, rated temperature range, operating frequency and radiating characteristics as standard rating and ch

35、aracteristics were added, identification, marking and labeling was added, IEC 61196-4:2015 IEC 2015 5 the tables of test procedures were revised, quality assessment and packaging was added, Annex C, “Coupling loss around circumferential orientation of radiating cable” was added Annex D “Radiating in

36、tensity around circumferential orientation of radiating cable” was added. The text of this standard is based on the following documents: FDIS Report on voting 46A/1256/FDIS 46A/1273/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in

37、 the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This publication is to be read in conjunction with IEC 61196-1:2005. A list of all the parts in the IEC 61196 series published under the general title Coaxial communication cables can be found on t

38、he IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, rep

39、laced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 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. Us

40、ers should therefore print this document using a colour printer. 6 IEC 61196-4:2015 IEC 2015 COAXIAL COMMUNICATION CABLES Part 4: Sectional specification for radiating cables 1 Scope This part of IEC 61196 applies to radiating coaxial communication cables. These cables are intended for use in wirele

41、ss communication systems, such as tunnels, railways, highways, subways, elevators and other installations in which conventional antenna transmission is not satisfactory or even impossible. It is to be read in conjunction with IEC 61196-1:2005. 2 Normative references The following documents, in whole

42、 or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.
