Information technology - Generic cabling systems - Part 3: Industrial premises
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.

Informacijska tehnologija - Univerzalni sistemi polaganja kablov - 3. del: Industrijska okolja
Ta evropski standard določa univerzalno polaganje kablov, ki podpira širok razpon komunikacijskih storitev, vključno z avtomatizacijo, kontrolo procesov in nadzorom aplikacij za uporabo v industrijskih okoljih, ki so sestavljena iz ene ali več stavb na kampusu. Zajema uravnoteženo polaganje kablov in polaganje optičnih kablov. Ta evropski standard temelji na sklicih in zahtevah EN 50173-1. Ta evropski standard vsebuje dodatne zahteve, ki so primerne za industrijska okolja, kjer je največja razdalja, na kateri je treba distribuirati komunikacijske storitve, 10.000 m. Načela tega mednarodnega standarda prav tako lahko veljajo za postavitve, ki niso v tem razponu.

This European Standard was approved by CENELEC on 2007-09-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,

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 net
