GENERIC CABLING FOR CUSTOMER PREMISES
Part 3: Industrial premises
FOREWORD

1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)

form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC

participate in the development of International Standards through technical committees established by the

respective organization to deal with particular fields of technical activity. ISO and IEC technical committees

collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in

liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have

established a joint technical committee, ISO/IEC JTC 1.

2) The formal decisions or agreements of IEC and ISO 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 and ISO member bodies.

3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted

by IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to

ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO 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 and ISO member bodies undertake to

apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and

regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding

national or regional publication should be clearly indicated in the latter.

5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are 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 ISO or its directors, employees, servants or agents including individual experts

and members of their technical committees and IEC National Committees or ISO member bodies 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 of, use of, or reliance upon, this ISO/IEC

publication or any other IEC, ISO or ISO/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 ISO/IEC publication may be the subject of

patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

International Standard ISO/IEC 11801-3 was prepared by subcommittee 25: Interconnection

of information technology equipment, of ISO/IEC joint technical committee 1: Information

technology.

This first edition cancels and replaces ISO/IEC 24702:2006 and Amendment 1:2009. This

edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) standard re-structured to contain only those requirements that are specific for generic

cabling systems installed in industrial premises;

b) support of critical process control, monitoring and automation (PCMA) services between

automation islands by adding new Annex A (normative) “Industrial cabling system”;

c) support of specific requirements for industrial cabling the end-to-end link (E2E) has been

introduced and delivers additional channel configuration covered in Annex B (normative);

d) silica optical fibre cabling has been removed from this International Standard.

INTRODUCTION

The importance of cabling infrastructure is similar to that of other fundamental utilities such as

water and energy supply and interruptions to the services provided over that infrastructure

can have a serious impact. A lack of design foresight, the use of inappropriate components,

incorrect installation, poor administration or inadequate support can threaten quality of service

and have commercial consequence for all types of users.

This document specifies generic cabling, which is critical for providing robust services to the

automation islands in industrial premises, or industrial spaces within other types of building.

Additionally those premises can include
• office spaces for which generic cabling is specified in ISO/IEC 11801-2,
• data centre spaces for which generic cabling is specified in ISO/IEC 11801-5.

Generic cabling for distributed building services in industrial spaces is specified in

ISO/IEC 11801-6, which addresses all of the above premises and spaces within them.

This document has taken into account the correlation between all parts of the ISO/IEC 11801

series and the IEC 61918 and IEC 61784-5 series.

Figure 1 shows the schematic and contextual relationships between the standards relating to

information technology cabling produced by ISO/IEC JTC 1/SC 25, namely the ISO/IEC 11801

series of standards for generic cabling design, standards for the installation, operation and

administration of generic cabling and for testing of installed generic cabling.

The generic cabling specified by this document provides users with

a) an application independent system capable of supporting a wide range of applications in a

range of installation and operating environments,
b) a flexible scheme such that modifications are both easy and economical,
c) a multi-vendor supply chain within an open market for cabling components.
In addition, this document provides

d) relevant industry professionals with guidance allowing the accommodation of cabling

before specific requirements are known, i.e. in the initial planning either for construction or

refurbishment and for further deployment as the requirements of areas are defined,

e) industry and standardization bodies with a cabling system which supports current products

and provides a basis for future product development and applications standardization.

Applications addressed in this document include those developed by the technical committees

of IEC (including the subcommittees of ISO/IEC JTC 1), including critical industrial process

control and monitoring applications and study groups of ITU-T.
As a result, this document

1) specifies a structure for generic cabling supporting a wide variety of applications,

2) adopts balanced cabling channel and link Classes D, E, E , F and F , specified in

A A
ISO/IEC 11801-1,

3) adopts component requirements, specified in ISO/IEC 11801-1, and specifies cabling

implementations that ensure performance of permanent links and of channels that meet or

exceed the requirements of a specified group (e.g. Class) of applications.

Figure 2 shows the relationship between all the documents (the generic cabling standards

produced by ISO/IEC JTC 1/SC 25 and the application-specific standards produced by

IEC SC 65C) that apply to industrial premises.

It is anticipated that the generic cabling system meeting the minimum requirements of this

document will have a life expectancy consistent with other infrastructures within industrial

premises.

This document has taken into account requirements specified in application standards listed

in ISO/IEC 11801-1:2017, Annex E. It refers to International Standards for components and

test methods whenever appropriate International Standards are available.

GENERIC CABLING FOR CUSTOMER PREMISES
Part 3: Industrial premises
1 Scope

This part of ISO/IEC 11801 specifies generic cabling for use within industrial premises, or

industrial areas within other types of premises, which can comprise single or multiple

buildings on a campus. It covers balanced cabling and optical fibre cabling.
This document is optimized for premises in which the maximum distance over which

telecommunications services can be distributed is 10 000 m. The principles of this document

can be applied to larger installations.

Cabling defined by this document supports a wide range of services, including automation,

process control, and monitoring applications. That can also incorporate the supply of power.

This document specifies directly or via reference to ISO/IEC 11801-1

a) the structure and minimum configuration for generic cabling within industrial premises,

b) the interfaces at the telecommunications outlet (TO),
c) the performance requirements for cabling links and channels,
d) the implementation requirements and options,
e) the performance requirements for cabling components,
f) the conformance requirements and verification procedures.

The cabling providing critical automation, process control and monitoring applications within

the automation islands is not addressed by this document. Information for this application-

specific cabling is provided in the IEC 61784-5 series (design) and in IEC 61918 (installation).

Safety (electrical safety and protection, fire, etc.) and electromagnetic compatibility (EMC)

requirements are outside the scope of this document, and are covered by other standards and

by regulations. However, information given by this document can be of assistance.
