29、r standardization comprising all national 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 publis
30、hes International Standards, Technical 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 pa
31、rticipate in this preparatory work. International, 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
32、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 each technical committee has representation from all interested IEC National Committees. 3) IEC Public
33、ations 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 IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or fo
34、r 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 their national and regional publications. Any divergence between any IEC Publication and the correspon
35、ding 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 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
36、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, employees, servants or agents including individual experts and members of its technical committees and IEC
37、 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 other IEC Publications. 8) Attent
38、ion 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 the subject of patent rights. IEC
39、 shall not be held responsible for identifying any or all such patent rights. International standard IEC 60096-0-1 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.
40、This third edition cancels and replaces the second edition published in 1990 and its Amendment 1 (2000). It constitutes a technical revision. The significant changes with respect to the previous edition are as follows: tables of material constants and factors and have been updated, different equatio
41、ns have been updated and corrected; a subclause dealing with the calculation of “Current carrying capacity of coaxial cables” has been added as Subclause 7.7. 60096-0-1 IEC:2012 5 The text of this standard is based on the following documents: FDIS Report on voting 46A/1043/FDIS 46A/1064/RVD Full inf
42、ormation on the voting for the approval of this standard can be found in the report on voting indicated in the above table. A list of all the parts in the IEC 60096 series, published under the general title Radio frequency cables, can be found on the IEC website. This publication has been drafted in
43、 accordance with the ISO/IEC Directives, Part 2. 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 w
44、ill be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 60096-0-1 IEC:2012 RADIO FREQUENCY CABLES Part 0-1: Guidelines to the design of detail specifications Coaxial cables 1 Scope This part of IEC 60096 provides guidance for the design of radio frequency coaxial cables with brai
