Information technology - Cabling installation - Part 1: Installation specification and quality assurance
This European Standard specifies requirements for the following aspects of information technology cabling: a) installation specification, quality assurance documentation and procedures; b) documentation and administration; c) operation and maintenance. This European Standard is applicable to all types of information technology cabling including generic cabling systems designed in accordance with the EN 50173 series of standards. 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.
Informationstechnik - Installation von Kommunikationsverkabelung - Teil 1: Installationsspezifikation und Qualitätssicherung
Diese Europäische Norm spezifiziert Anforderungen für folgende Aspekte der informationstechnischen Verkabelung: a) Spezifikation der Installation sowie Dokumentation und Verfahren der Qualitätssicherung; b) Dokumentation und Verwaltung; c) Betrieb und Instandhaltung. Diese Europäische Norm ist für alle Arten von informationstechnischer Verkabelung anwendbar, einschließlich anwendungsneutraler Verkabelung, die in Übereinstimmung mit den Normen der Reihe EN 50173 entworfen wurde. Die Sicherheit (elektrische Sicherheit und Schutz, optische Leistung, Feuer, usw.) und die Anforderungen an die elektromagnetische Verträglichkeit (EMV) sind nicht Bestandteil dieser europäischen Norm und werden durch andere Normen und Vorschriften geregelt. Jedoch können Informationen in dieser europäischen Norm enthalten sein, welche die Einhaltung der Anforderungen dieser Normen und Vorschriften unterstützen.

This European Standard was approved by CENELEC on 2009-05-01. 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,
Sweden, Switzerland and the United Kingdom.

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 50174-1 on
2009-05-01.
This European Standard supersedes EN 50174-1:2000.
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) 2010-05-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-05-01
EN 50174 comprises three parts. All three parts support the specification, implementation and operation of
information technology cabling. There are specific requirements for cabling systems that are in accordance
with the design requirements of the EN 50173 series. However, the three parts also apply to cabling systems
of any design including those in accordance with standards such as EN 50098-1 or EN 50098-2.
This part, EN 50174-1, is concerned with specification, quality assurance, documentation and administration
of information technology cabling to be installed, together with its subsequent operation and maintenance. It
sets out the responsibilities of information technology cabling installers and premises owners or appointed
representatives separately, and is intended to be referenced in relevant contracts.
It does not cover those aspects of installation associated with the transmission of signals in free space
between transmitters, receivers or their associated antenna systems (e.g. wireless, radio, microwave or
satellite).
