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.

Introduction
The importance of services delivered by information technology cabling infrastructure is similar to that of
utilities such as heating, lighting and electricity supplies. As with those utilities, interruptions to service can
have a serious impact. Poor quality of service due to lack of planning, use of inappropriate components,
incorrect installation, poor administration or inadequate support can threaten an organisation’s effectiveness.
There are four phases in the successful implementation of information technology cabling. These are:
a) design;
b) specification – the detailed requirement for the cabling, including the planning of its accommodation and
associated building services addressing specific environments (e.g. electromagnetic) together with the
quality assurance requirements to be applied;
c) installation – in accordance with the requirements of the specification;
d) operation – the management of connectivity and the maintenance of transmission performance during
the life of the cabling.
This European Standard is in three parts and addresses the specification, installation and operational
aspects. The EN 50173 series and other application standards cover design issues.
EN 50174-1 is used during the specification phase. It addresses the:
– installation specification, quality assurance documentation and procedures;
– documentation and administration;
– operation and maintenance.
This part, EN 50174-2, and EN 50174-3 are intended to be used by the personnel directly involved in the
planning aspects (of the specification phase) and installation phase. EN 50174-2 is applicable inside
buildings and EN 50174-3 is applicable outside buildings.
This European Standard is also relevant to:
• architects, building designers and builders;
• main contractors;
• designers, suppliers, installers, inspectors (auditors), maintainers and owners of information technology
cabling;
• public network providers and local service providers;
• end users.
This part, EN 50174-2, contains requirements and recommendations relating to the installation planning and
practices by defining:
i) planning strategy (road map) and guidance depending on the application, electromagnetic environment,
building infrastructure and facilities, etc.;
ii) planning and installation requirements for metallic and optical fibre information technology cabling
depending on the application, electromagnetic environment, building infrastructure and facilities, etc.;
iii) the practices and procedures to be adopted to ensure that the cabling is installed in accordance with the
specification.

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) 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.
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 equipotential 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, including safety, shall be met.
The responsibilities for specific elements of conformance may be made by national-specific amendment of
Annex B.
