European foreword
This document (EN 50173-3:2018) has been prepared by the Technical Committee CENELEC TC 215
"Electrotechnical aspects of telecommunication equipment".
The following dates are fixed:
• latest date by which this document has (dop) 2019-03-19
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2021-03-19
standards conflicting with this document
have to be withdrawn
This document supersedes EN 50173-3:2007 + A1:2010 + AC:2011.
The European Standards EN 50173:1995 and EN 50173-1:2002 have been developed to enable the
application-independent cabling to support ICT applications in office premises. Their basic principles,
however, are applicable to other types of applications and in other types of premises.
TC 215 has decided to establish relevant European Standards which address the specific requirements of
these premises. In order to point out the commonalities of these cabling design standards, these EN are
published as individual parts of the series EN 50173, thus also acknowledging that standards users recognize
the designation “EN 50173” as a synonym for generic cabling design.
At the time of publication of this European Standard, series EN 50173 comprises the following standards:
EN 50173-1 Information technology – Generic cabling systems – Part 1: General requirements
EN 50173-2 Information technology – Generic cabling systems – Part 2: Office premises
EN 50173-3 Information technology – Generic cabling systems – Part 3: Industrial spaces
EN 50173-4 Information technology – Generic cabling systems – Part 4: Homes
EN 50173-5 Information technology – Generic cabling systems – Part 5: Data centres
EN 50173-6 Information technology – Generic cabling systems – Part 6: Distributed building services
This European Standard, EN 50173-3, contains specific requirements for generic cabling systems intended to
be operated in industrial premises, referencing the general requirements of EN 50173-1:2018
This edition of EN 50173-3:
a) introduces new balanced cabling component Categories 8.1 and 8.2 to support new channel Classes I
and II;
b) introduces a new cabled optical fibre Category OM5 and Category OS1a;
c) introduces a new Annex on the industrial cabling subsystem;
d) amends various other subclauses, tables and figures;
e) aligns the document structure across the EN 50173 series and updates the document both technically
and editorially.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
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 consequences for all types of users.
This standard specifies generic cabling to serve 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 EN 50173-2;
— data centre spaces for which generic cabling is specified in EN 50173-5.
Generic cabling for distributed building services in industrial spaces is specified in EN 50173-6 which
addresses all of the above premises and spaces within them.
Figure 1 and Table 1 show the schematic and contextual relationships between the standards produced by
TC 215 for information technology cabling, namely:
1) this and other parts of the EN 50173 series;
2) installation (EN 50174 series);
3) bonding (EN 50310).

In addition, a number of Technical Reports have been developed to support or extend the application of these
standards, including:
— CLC/TR 50173-99-1, Cabling guidelines in support of 10 GBASE-T;
— CLC/TR 50173-99-2, Information technology — Implementation of BCT applications using cabling in
accordance with EN 50173-4;
— CLC/TR 50173-99-3, Information technology — Generic cabling systems — Part 99-3: Home cabling
infrastructures up to 50 m in length to support simultaneous and non simultaneous provision of
applications.
In addition, a number of cabling design standards have been developed using components of EN 50173-1
(e.g. EN 50098 series and EN 50700).
The generic cabling specified by this standard provides users with:
— an application independent system capable of supporting a wide range of applications in a range of
installation and operating environments;
— a flexible scheme such that modifications are both easy and economical;
— a multi-vendor supply chain within an open market for cabling components.
In addition this standard provides:
a) 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;
b) 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 standard include those developed by the Technical Committees of IEC
(including the subcommittees of ISO/IEC JTC 1) a
