1.1 Scope
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. 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) describes the methodology for the assessment of spaces, pathways (and pathway systems) and cabling (either installed or planned) in support of remote powering objectives;
3) excludes specific requirements applicable to other cabling systems (e.g. power supply cabling); however, it takes account of the effects other cabling systems have on the installation of information technology cabling (and vice versa) and gives general advice;
4) 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. It does not exclude additional requirements which are applicable in particular circumstances, defined by e.g. electricity supply and electrified railways.
1.2 Conformance
For a cabling installation to conform to this European Standard:
a) the planning of the installation shall meet the requirements of Clause 4;
b) the installation practices shall meet the requirements of Clause 5;
c) the additional requirements of the applicable premises-specific clause shall be met;
d) the bonding system within the premises shall be in accordance with EN 50310;
e) where a lightning protection system is required, it shall conform to the “integrated lightning protection system" according to EN 62305-4;
f) other lightning protection systems, including the “isolated lightning protection system” according to EN 62305-3 are allowed provided that specific restrictions are applied both to the implementation of the information technology cabling and the requirements of EN 50310 as agreed between the planners of the lightning protection system and the information technology cabling;
g) local regulations shall be met.
The responsibilities for specific elements of conformance may be made by national-specific amendment of Annex B.
