Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 215, Electrotechnical
aspects of telecommunication equipment.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50173-3 on
2007-09-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-09-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-09-01
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 premises
EN 50173-4 Information technology – Generic cabling systems – Part 4: Homes
EN 50173-5 Information technology – Generic cabling systems – Part 5: Data centres
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 50173-1:2007. It is based upon
but is not identical to ISO/IEC 24702:2006, Information technology - Generic cabling - Industrial premises.

Introduction
The importance of the information technology cabling infrastructure is similar to that of other utilities such as
heating, lighting and electricity supplies. As with other utilities, interruptions to service can have serious impact.
Poor quality of service due to lack of planning, use of inappropriate components, incorrect installation, poor
administration or inadequate support can threaten an organisation's effectiveness.
Historically, the cabling within premises comprised both application-specific and multipurpose networks.
Standards within the EN 50173 series have enabled a controlled migration to generic cabling (with an
associated reduction in the use of application-specific cabling) and supported the development of high data
rate applications based upon defined cabling models.
This European Standard, EN 50173-3, recognizes the benefit of generic cabling to interconnect several pieces
of apparatus within industrial premises (within and between structures and buildings) and is to be read in
conjunction with EN 50173-1.
This European Standard provides, for industrial premises:
a) users with an application independent generic cabling system and an open market for cabling components;
b) requirements for infrastructures that support critical automation, process control and monitoring applications
in a range of industrial environments;
c) users with a flexible cabling scheme such that modifications are both easy and economical;
d) building professionals (for example, architects), production and control engineers with guidance allowing the
accommodation of cabling both before specific requirements are known, i.e. in the initial planning either for
construction or refurbishment, and for further deployment as the requirements of specific industrial areas
are defined;
e) industry and standardisation bodies with a cabling system which supports current products and provides a
basis for future product development and applications standardisation.
This European Standard specifies multi-vendor cabling, and is related to:
- the associated standard covering general requirements for generic cabling within premises (EN 50173-1);
- standards for cabling components developed by Technical Committees of CENELEC and/or IEC;
- standards for the quality assurance and installation of information technology cabling (series EN 50174)
and testing of installed cabling (EN 50346);
- applications developed by the technical bodies of IEC (including the subcommittees of ISO/IEC JTC 1),
study groups of ITU-T and CENELEC TC 65CX “Fieldbus”.
Within this European Standard the cabling, defined between the interfaces shown in Figure 1, contains
passive components only.
The applications listed in EN 50173-1:2007, Annex F, have been analysed to determine the requirements for a
generic cabling system. These requirements, together with statistics concerning premises geography from
different countries and the models described in Clause 6, have been used to develop the requirements for
cabling components and to stipulate their arrangement into cabling systems. As a result, generic cabling
defined within this European Standard is targeted at, but not limited to, industrial premises.
It is anticipated that the generic cabling system meeting the minimum requirements of this European Standard
will have a life expectancy consistent with other infrastructures within industrial premises.

1 Scope and conformance
1.1 Scope
This European Standard specifies generic cabling that supports a wide range of communications services
including automation, process control and monitoring applications for use within industrial premises comprising
single or multiple buildings on a campus. It covers balanced cabling and optical fibre cabling.
This European Standard is based upon and references the requirements of EN 50173-1. This European
Standard contains additional requirements that are appropriate to industrial premises in which the maximum
distance over which communications services have to be distributed is 10 000 m. The principles of this
European Standard may also be applied to installations that do not fall within this range.
In addition to the requirements of EN 50173-1, this European Standard specifies:
a) a modified structure and configuration for generic cabling within industrial premises in which information
technology applications are used to support process monitoring and control functions;
b) implementation options;
c) additional requirements that reflect the range of operating environments within industrial premises.
Safety (electrical safety and protection, optical power, fire, etc.) and electromagnetic compatibility (EMC)
requirements are outside the scope of this European Standard and are covered by other Standards and
regulations. However, information given in this European Standard may be of assistance in meeting these
Standards and regulations.
1.2 Conformance
For a cabling system to conform to this European Standard:
a) the structure and configuration shall conform to the requirements of Clause 4;
b) the interfaces to the cabling at the telecommunications outlet shall conform to the requirements of
Clause 8 with respect to mating interfaces and performance;
c) connecting hardware at other places in the cabling structure shall conform to the requirements of
Clause 8;
1)
d) the performance of channels shall conform to the applicable transmission performance requirements of
Clause 5. This shall be achieved by one of the following:
- a channel design and implementation ensuring that the prescribed channel performance Class of
Clause 5 is met;
- attachment of appropriate components to a permanent link design meeting the prescribed perfor-
mance Class of Annex A. Channel performance shall be assured where a channel is created by
adding more than one cord to either end of a permanent link meeting the requirements of Annex A;
- using the reference implementations of Clause 6 and compatible cabling components conforming to
the requirements of Clauses 7, 8 and 9, based upon a statistical approach of performance modelling.
e) local regulations concerning safety and electromagnetic emissions shall be met.
———————
1)
This term, as defined in EN 50173-1, refers to the passive cabling between the interfaces described in Clauses 4 and 5. Different
definitions of the term “channel” as given in other standards are not applicable in this European Standard.
---------------------- Page: 10 ----------------------
EN 50173-3:2007 - 10 -
In addition the following requirements of the EN 50174 series of Standards shall be met:
f) installation specification and quality planning to address:
- the test parameters to be measured;
- the sampling levels to be applied;
- the treatment of channels or links which fail to meet requirements or for which test results lie within the
relevant measurement accuracy;
g) administration;
h) installation.
Test methods to verify conformance with the channel and link requirements of Clause 5 and Annex A
respectively are specified in EN 50346. Neither this Standard nor EN 50174-1 specify the test and sampling
levels to be adopted.
Specifications marked "ffs" (for further study) in EN 50173-1 are preliminary and are not required for
conformance to this European Standard.
