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 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 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.
