FOREWORD
1) The International Electrotechnical Commission (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 in
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 interested 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
accordance 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 interested
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 responsible 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 between any
IEC Publication and the corresponding national or regional publication shall be clearly 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 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 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 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 responsible for identifying any or all such patent rights.

International Standard IEC 61156-5-1 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 second edition cancels and replaces the first edition published in 2002. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) new requirements for new cables Cat6 , Cat7 , for 10 GBase-T applications;
A A
b) revised requirements and tests for the cables.

46C/817/FDIS 46C/825/RVD
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.

This specification is to be used in conjunction with IEC 61156-1 and IEC 61156-5.
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.
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
related to the specific publication. At this date, the publication will be

MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES

FOR DIGITAL COMMUNICATIONS –
Part 5-1: Symmetrical pair/quad cables with transmission

characteristics up to 1 000 MHz – Horizontal floor wiring –

Blank detail specification
1 Scope
This part of IEC 61156 describes symmetrical pair/quad cables intended for horizontal floor cabling
in class D, E, E , F and F channels (Cat 5e, Cat 6, Cat 6 , Cat 7, Cat 7 ) as defined in ISO/IEC
A A A A
11801 and ISO/IEC 24702.
NOTE Cabling for various severities of industrial environments is specified in ISO/IEC 24702. Environmental
classifications are presented in ISO/IEC 24702 with three levels of severity in four areas: mechanical, ingress, climatic,
and electromagnetic; thus, in tabular form, they are referred to as the “MICE table”.
This blank detail specification includes additional recommended environmental characteristics and
severities, which are derived from the environmental classifications that are specified for cabling
for industrial environments.
The blank detail specification determines the layout and style for detail specifications describing
symmetrical pair
