This European Standard was approved by CENELEC on 2011-04-01. 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, Croatia,
Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,

Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 215, Electrotechnical
rd
aspects of telecommunication equipment. This 3 edition of EN 50173-1 replaces the text of
EN 50173-1:2007, EN 50173-1:2007/A1:2009 and consolidates these two standards with the text of
EN 50173-1:2007/FprAB:2010 for the convenience of the user of the standard.
The text of draft amendment EN 50173-1:2007/FprAB was submitted to the Formal Vote and was approved
by CENELEC to amend EN 50173-1:2007 on 2011-04-01.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent rights.
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) 2012-04-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-04-01
The previous editions of 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 ENs are
published as individual parts of the series EN 50173, thus also acknowledging that standards users recog-
nize 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 edition of EN 50173-1:
a) contains a change of electromagnetic parameters in the MICE classification (Table 3);
b) introduces new component Categories 6 and 7 in accordance with the channel Classes E and F
A A A A
defined in EN 50173-1:2007/A1:2009;
c) modifies insertion loss requirements for coaxial channels;
d) modifies optical fibre Class OF-100 media and defines a new cabled optical fibre Category OM4;
e) amends and modifies connecting hardware requirements, defines both a new interface for 2 optical fibres
and for 12 and 24 fibres;
f) introduces limits for additional parameters in Annexes A, B and D.2;
g) revises D.3 regarding test requirements for mechanical and environmental performance of connecting
hardware;
h) updates Annex F “Supported applications”;

i) introduces a new normative Annex I “Test procedures to assess conformance with EN 50173 standards”;
j) amends various other subclauses, tables and figures.
