11、CTROTECHNICAL COMMISSION _ MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 3-1: Work area wiring Blank detail specification FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechni
12、cal 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 Standards, Technical Specifications,
13、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 preparatory work. International, gove
14、rnmental 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 organizations. 2) The formal decisions
15、 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 of recommendations for internatio
16、nal 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 misinterpretation by any end user. 4) In order t
17、o 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 regional publication shall be clearly
18、 indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered 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 a
19、ttach 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 nature whatsoever, whether direct or indirect, or for costs (including legal f
20、ees) 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 publications is indispensable for the correct application of this publica
21、tion. 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. International Standard IEC 61156-3-1 has been prepared by subcommittee 46C: Wires and
22、 symmetric cables, of IEC technical committee 46: Cables, wires, waveguides, r.f. connectors, r.f. and microwave passive components and accessories. This standard is to be read in conjunction with IEC 61156-1: 2002 and IEC 61156-3: 2008. This third edition cancels and replaces the second edition pub
23、lished in 2003. This edition constitutes a technical revision. The significant global technical change is the alignment with IEC 61156-3: 2008. 4 61156-3-1 IEC:2009(E) The text of this standard is based on the first edition and on the following documents: FDIS Report on voting 46C/883/FDIS 46C/891/R
24、VD Full information on the voting for 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. A list of all parts of the IEC 61156 series, published under the general title M
25、ulticore and symmetrical pair/quad cables for digital communications, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data relat
26、ed to the specific publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 61156-3-1 IEC:2009(E) 5 MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATION
27、S Part 3-1: Work area wiring Blank detail specification 1 Scope The application of this blank detail specification relates to multicore and symmetrical pair(s)/ quad(s) cables for digital communications in work area wiring. This blank detail specification determines the layout and style for detail s
28、pecifications describing multicore and symmetrical pair(s)/quad(s) cables for digital communication in work area wiring. Detail 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
29、referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 61156-1:2002 1 , Multicore and symmetrical pair/quad cables
30、 for digital communications Part 1: Generic specification IEC 61156-3, Multicore and symmetrical pair/quad cables for digital communications Part 3: Work area wiring Sectional specification 3 Guidance for preparation of detail specifications It is necessary to keep the transmission characteristics i
31、ndicated in the relevant sectional specification for the category number (3 or 5) and the characteristic impedance. The detail specification shall be written in accordance with the layout of the blank detail specification which forms part of this standard. NOTE When a characteristic does not apply,
32、then NA (for Not Applicable) should be entered in the appropriate space. When a characteristic applies but a specific value is not considered necessary, then NS (for Not Specified) should be entered in the appropriate space. The numbers shown in brackets on this and the following pages correspond to
33、 the following items of required information, which should 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 the document is available. _ 1A more re
34、cent 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 61156-3-1 IEC:2009(E) 4 Related documents. 5 Any other references to the cable, national reference, trade name, etc. 6
35、A complete description of the cable which shall include a) type and number of elements; b) nominal impedance; c) screening; d) application; e) category; f) other distinguishing performance characteristics. Example: Detail specification for 4-pairs cable without common screen for digital communicatio
