Information technology - Cabling installation - Part 2: Installation planning and practices inside buildings

This European Standard specifies requirements for the following aspects of information technology cabling: a) planning; b) installation practice. This European Standard is applicable to all types of information technology cabling inside buildings (and may be applied to cabling that is defined as part of the building) including generic cabling systems designed in accordance with the EN 50173 series of standards. The requirements of Clauses 4, 5 and 6 of this standard are premises-independent unless amended by the requirements of premises-specific clauses. This European Standard: 1) details the considerations for satisfactory installation and operation of information technology cabling; 2) excludes specific requirements applicable to other cabling systems (e.g. mains power cabling); however, it takes account of the effects other cabling systems may have on the installation of information technology cabling (and vice versa) and gives general advice; 3) excludes 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). This European Standard is intended for application within commercial and residential premises. This standard is applicable to certain hazardous environments but does not exclude additional requirements which are applicable in particular circumstances, defined by e.g. electricity supply and electrified railways.

Informationstechnik - Installation von Kommunikationsverkabelung - Teil 2: Installationsplanung und Installationspraktiken in Gebäuden

Diese Europäische Norm legt die Anforderungen an die folgenden Aspekte informationstechnischer Verkabelung fest: a) Planung; b) Installationspraktiken. Diese Europäische Norm gilt für alle Arten informationstechnischer Verkabelung innerhalb von Gebäuden (und kann auf Verkabelung angewendet werden, die als Teil des Gebäudes definiert ist), einschließlich anwendungsneutraler Verkabelungsanlagen, die nach der Normenreihe EN 50173 ausgelegt sind. Die in den Abschnitten 4, 5 und 6 dieser Norm gestellten Anforderungen sind, sofern sie nicht von den Anforderungen in den „gebäudespezifischen“ Abschnitten aufgehoben werden, gebäudeunabhängig. Diese Europäische Norm: 1) geht ausführlich auf Überlegungen bezüglich einer zufriedenstellenden Installation und eines zufrieden¬stellenden Betriebs von informationstechnischer Verkabelung ein; 2) schließt besondere Anforderungen aus, die bei anderen Verkabelungssystemen gelten (z. B. bei Stromversorgungsleitungen), berücksichtigt allerdings die Auswirkungen, die andere Verkabelung auf die Installation informationstechnischer Verkabelung (und umgekehrt) haben kann und gibt allgemeine Ratschläge; 3) schließt diejenigen Aspekte der Installation aus, die mit der Freiraumübertragung von Signalen zwischen Sendern, Empfängern oder deren zugehörigen Antennensystemen (z. B. drahtlos (Mobilfunk), Funk, Mikrowellen oder Satellit) im Zusammenhang stehen. Diese Europäische Norm ist zur Anwendung in gewerblichen Gebäuden und in Wohngebäuden vorgesehen. Diese Norm ist in bestimmten gefährlichen Umgebungen anwendbar, schließt jedoch keine zusätzlichen Anforderungen aus, die unter bestimmten Umständen gelten, z. B. bei Elektrizitätsversorgungsunternehmen und elektrifizierten Eisenbahnen.

Technologies de l'information - Installation de câblages - Partie 2: Planification et pratiques d'installation à l'intérieur des bâtiments

La présente Norme Européenne spécifie les exigences relatives aux aspects du câblage des technologies de l’information suivants: a) la planification; b) les pratiques en matière d’installation. La présente Norme Européenne s’applique à tous les types de câblage des technologies de l’information à l’intérieur des bâtiments (et il est admis qu’elle s’applique au câblage qui est défini comme partie du bâtiment), y compris les systèmes génériques de câblage conçus conformément à la série de normes EN 50173. Les exigences des Articles 4, 5 et 6 de la présente norme sont indépendantes des locaux, sauf si elles sont modifiées par les exigences contenues dans des articles spécifiques à ces locaux particuliers. La présente Norme Européenne: 1) analyse les points à observer pour une installation et une exploitation satisfaisante d’un câblage des technologies de l’information; 2) exclut les exigences particulières applicables à d’autres systèmes de câblage (par exemple, le câblage d’alimentation en énergie); cependant elle tient compte des effets que d’autres systèmes de câblage peuvent avoir sur l’installation du câblage dédié aux technologies de l’information (et vice versa) et donne des conseils appropriés; 3) exclut des aspects de l’installation liés à la transmission de signaux en espace libre entre émetteurs-récepteurs ou leurs systèmes d’antennes correspondants (par exemple les liaisons sans fil, radio, hyperfréquences ou satellite). La présente Norme Européenne est destinée à être mise en œuvre dans les locaux commerciaux et résidentiels. La présente norme s’applique à certains environnements à risque, mais n’exclut pas des exigences additionnelles applicables dans des circonstances particulières, définies par exemple par les autorités en charge de la distribution électrique et des chemins de fer électrifiés.

Informacijska tehnologija - Polaganje kablov - 2. del: Načrtovanje inštalacij in tehnike dela v stavbah

Ta evropski standard določa zahteve za naslednje vidike kablov za informacijsko tehnologijo: a) načrtovanje; b) tehnike dela pri polaganju. Ta evropski standard velja za vse vrste kablov za informacijsko tehnologijo v stavbah (in lahko velja za kable, ki so opredeljeni kot del stavbe), vključno z rodovnimi kabelskimi sistemi, narejenimi v skladu s serijo EN 50173. Zahteve klavzul 4, 5 in 6 tega standarda niso odvisne od prostorov, razen če jih spreminjajo zahteve klavzul, specifičnih za prostore.

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 50174-2 on
2009-05-01.
This European Standard supersedes EN 50174-2:2000.
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 50174-2, is concerned with the planning and installation of information technology cabling
using metallic cabling and optical fibre cabling inside buildings. It provides guidance as to the responsibilities
of those involved and is intended to be referenced in relevant contracts.
Additional clauses containing normative requirements for specific types of premises will be added as
amendments, or as revisions, to this standard. At the time of publication of this European Standard, the
following clauses are planned:
– homes;
– data centres;
– operator buildings.
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).
This document contains two informative annexes:
– Annex A, providing information on EMC and protection;
– Annex B, containing a minimum set of responsibilities applicable to installers and enabling national-
specific amendment to define other responsibilities.
