11、2010(E) 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 2-1: Horizontal floor wiring Blank detail specification FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization com
12、prising 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 publishes International Sta
13、ndards, 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 participate in this pre
14、paratory 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 between the two orga
15、nizations. 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 Publications have the form
16、 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 for any misinterpretat
17、ion 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 corresponding national or reg
18、ional 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 services carried out
19、 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 National Committees
20、 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) Attention is drawn to the
21、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 shall not be held r
22、esponsible for identifying any or all such patent rights. International Standard IEC 61156-2-1 has been prepared by subcommittee 46C: Wires and symmetric cables, of IEC technical committee 46: Cables, wires, waveguides, r.f. connectors, r.f. and microwave passive components and accessories. This thi
23、rd edition cancels and replaces the second edition published in 2003. This edition constitutes a technical revision and takes into account the technical changes made in the IEC 61156-2, Edition 3 (2010). This sectional specification relates to IEC 61156-2:2010. The cables are specifically intended f
24、or horizontal floor wiring as defined in ISO/IEC 11801:1995. 4 61156-2-1 IEC:2010(E) The text of this technical report is based on the following documents: CDV Report on voting 46C/900/CDV 46C/913/RVC Full information on the voting for the approval of this technical report can be found in the report
25、 on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 61156 series, under the general title: Multicore and symmetrical pair/quad cables for digital communications, can be found on the IEC website.
26、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 will be reconfirmed, withdrawn, replaced by a revi
27、sed edition, or amended. A bilingual version of this publication may be issued at a later date. 61156-2-1 IEC:2010(E) 5 MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 2-1: Horizontal floor wiring Blank detail specification 1 Scope This blank detail specification relates t
28、o multicore and symmetrical pair/quad cables for digital communications in horizontal floor wiring. This blank detail specification determines the layout and style for detail specifications describing multicore and symmetrical pair/quad cables for digital communication in horizontal floor wiring. De
29、tail specifications based on the blank detail specification may be prepared by a national standards organization, a manufacturer or a user. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited a
30、pplies. For undated references, the latest edition of the referenced document (including any amendments) applies.

31、 digital communications Part 2: Symmetrical pair/quad cables with transmission characteristics up to 100 MHz Horizontal floor wiring Sectional specification 3 Guidance for preparation of detail specifications It is necessary to keep the transmission characteristics indicated in the relevant sectiona
32、l specification for the category number (3 or 5) and the characteristic impedance. NOTE When a characteristic does not apply, then NA (for Not Applicable) may be entered in the appropriate space. When a characteristic applies but a specific value is not considered necessary, then NS (for Not Specifi
33、ed) should be entered in the appropriate space. _ 1)A more recent version of this standard exists (2007), but as not all of the tests cited herein are addressed by the newer edition, it has been decided that the 2002 edition is to be used. 6 61156-2-1 IEC:2010(E) The numbers shown in brackets in thi
34、s and the following pages correspond to the following items of required information which shall be entered in the spaces provided. 1 Name and address of the organization that has prepared the document. 2 IEC document number, issue number and date of issue. 3 Address of the organization from which th
