11、ssion (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 standardization in the electrical and electronic fields. To this end and i
12、n 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 entrusted to technical committees; any IEC National Committee i
13、nterested 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 International Organization for Standardization (ISO) in accordan
14、ce 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 each technical committee has representation from all intere
15、sted 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 IEC Publications is accurate, IEC cannot be held responsib
16、le 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 their national and regional publications. Any divergence be
17、tween 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 assessment services and, in some areas, access to IEC marks of
18、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, employees, servants or agents including individual experts and
19、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 the publication, use of, or reliance upon, this IEC Publicati
20、on 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 possibility that some of the elements of this IEC Publicati
21、on may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has colle
22、cted data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC TR 61156-1-6, which is a technical report, has been prepared by subcommittee 46C: Wires and symmetric cables, of IEC technical committee 46: Cables, wires, waveguides
23、, RF connectors, RF and microwave passive components and accessories. PD IEC/TR 61156-1-6:2016 4 IEC TR 61156-1-6:2016 IEC 2016 The text of this technical report is based on the following documents: Enquiry draft Report on voting 46C/1044/DTR 46C/1051/RVC Full information on the voting for the appro
24、val of this technical report can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 61156 series, published under the general title Multicore and symmetrical pair/quad cables
25、for digital communications, can be found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document
26、 will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date.

34、available at http:/www.iso.org/obp 4 Overview Measurement of thermal heating /1/ or other analysis of applications such as POE /2/ or other remote powering application requires DC-resistance values reflecting the higher performance of higher categories not explicitly specified in IEC 61156-5, IEC 61
35、156-6, IEC 61156-9 and PD IEC/TR 61156-1-6:2016 6 IEC TR 61156-1-6:2016 IEC 2016 IEC 61156-10. This document therefore informatively provides such values for horizontal floor wiring and work area wiring taking into account different possible basic designs. 5 DC-resistance values 5.1 General IEC 6115
36、6-5, IEC 61156-6, IEC 61156-9 and IEC 61156-10 only have a basic DC-resistance requirement each, possible to be fulfilled by cables of the lowest category. As higher categories provide a better attenuation, also the DC-resistance of such a cable is lower, even though not required, as cabling standar
37、ds also do not require more severe values for higher Classes /3/. The DC-resistance of a balanced pair is basically dependent on conductivity and diameter of the wires. During the stranding process, the wires are forced on certain trajectories that are defined by lay-lengths, diameter of insulation
38、and the dimensions of possible fillers and foils being applied during stranding. Due to the inevitable forces needed to form the insulated wires, the diameter of the conductors is slightly reduced while being stranded. As the measurement of the resulting conductor diameter is a measurement at a disc
39、rete point and thus less representative of the entire length of the cable and, furthermore, achieving a low measurement uncertainty requires a significant technical effort, the following tables only roughly indicate the conductor diameter. The nominal DC-resistance values given in Tables 1, 2 and 3
40、below are to be understood as typical values. No requirements therefore can be derived from these values. Continuous progress of technical development might result in cable designs fulfilling all current requirements of IEC 61156-5, IEC 61156-6, IEC 61156-9 or IEC 61156-10 respectively (including th
41、e request for copper conductors), but having higher DC-resistance than indicated in Tables1, 2 and 3 below. The use of cables with a lower DC-resistance than indicated is possible and might provide benefit with respect to thermal heating and possibly further performance parameters. 5.2 Values for ho
42、rizontal floor wiring cables Cables for horizontal floor wiring according to IEC 61156-5 and IEC 61156-9 have a design based on solid copper wires. Shorter lay-lengths are necessary to obtain a better crosstalk performance. As shorter lay-lengths lead to increased attenuation, such designs need a la
43、rger conductor diameter to achieve attenuation requirements. Also foils e.g. applied as pair shielding add to attenuation and accordingly high category pair-shielded cables need higher conductor diameters, too. Table 1 provides nominal values for the conductor diameter and resistance for horizontal
44、floor wiring cables.

Therefore, both cases are reflected in Table 2. The explanations with respect to the relation between cable
