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).

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.
The requirements and recommendations of Clause 4 are primarily for owners of premises housing
information technology systems. The owners may delegate selected responsibilities to designers, specifiers,
operators and maintainers of installed information technology cabling.
The requirements and recommendations of Clause 5 are primarily for the installers of information technology
cabling.
Figure 1 and Table 1 show the schematic and contextual relationships between the standards produced by
CLC/TC 215 for information technology cabling, namely:
1) this and other parts of the EN 50174 series;
2) generic cabling design (EN 50173 series);
3) application dependent cabling design (e.g. EN 50098 series);
4) testing of installed cabling (EN 50346);
5) equipotential bonding requirements (EN 50310).

1 Foreword
2 This draft European Standard has been prepared by Technical Committee CENELEC/TC 215
3 „Electrotechnical aspects of telecommunication equipment". It is submitted to the CENELEC enquiry.
4 This European Standard will supersede EN 50174-1:2000.
5 EN 50174 comprises three parts. All three parts support the specification, implementation and operation of
6 information technology cabling. There are specific requirements for cabling systems that are in accordance
7 with the design requirements of the EN 50173 series of standards. However, the three parts also apply to
8 cabling systems of any design including those in accordance with standards such as EN 50098-1 or
9 EN 50098-2.
10 This part, EN 50174-1, is concerned with specification, quality assurance, documentation and administration
11 of information technology cabling to be installed, together with its subsequent operation and maintenance. It
12 sets out the responsibilities of information technology cabling installers and premises owners separately, and
13 is intended to be referenced in relevant contracts.
14 It does not cover those aspects of installation associated with the transmission of signals in free space
15 between transmitters, receivers or their associated antenna systems (e.g. wireless, radio, microwave or
16 satellite).
17 Annexes designated "informative" are given for information only. In this standard, Annexes A and B are
18 normative, Annexes C and D are informative.
19 To ease the commenting during the development of this draft line numbers have been included; they will be
20 suppressed in the final document.

75 Introduction
76 The importance of services delivered by information technology cabling infrastructure is similar to that of
77 utilities such as heating, lighting and electricity supplies. As with those utilities, interruptions to service can
78 have a serious impact. Poor quality of service due to lack of planning, use of inappropriate components,
79 incorrect installation, poor administration or inadequate support can threaten an organisation’s effectiveness.
80 There are four phases in the successful implementation of information technology cabling. These are
81 a) design;
82 b) specification – the detailed requirement for the cabling, including the planning of its accommodation and
83 associated building services addressing specific environments (e. g. electromagnetic) together with the
84 quality assurance requirements to be applied;
85 c) installation – in accordance with the requirements of the specification;
86 d) operation – the management of connectivity and the maintenance of transmission performance during
87 the life of the cabling.
88 This European Standard is in three parts and addresses the specification, installation and operational
89 aspects. The EN 50173 series of standards and other application standards cover design issues.
90 EN 50174-1 is used during the specification phase. It addresses the
91 – installation specification, quality assurance documentation and procedures;
92 – documentation and administration;
93 – operation and maintenance.
94 This part, EN 50174-2 and EN 50174-3 are intended to be used by the personnel directly involved in the
95 planning aspects (of the specification phase) and installation phase. EN 50174-2 is applicable inside
96 buildings and EN 50174-3 is applicable outside buildings.
97 This European Standard is also relevant to
98 • architects, building designers and builders;
99 • main contractors;
100 • designers, suppliers, installers, inspectors (auditors), maintainers and owners of information technology
101 cabling;
102 • public network providers and local service providers;
103 • end users.
104 The requirements and recommendations of Clause 4 are primarily for owners of premises housing
105 information technology systems. The owners may delegate selected responsibilities to designers, specifiers,
106 operators and maintainers of installed information technology cabling.
107 The requirements and recommendations of Clause 5 are primarily for the installers of information technology
108 cabling.
109 Figure 1 and Table 1 show the schematic and contextual relationships between the standards produced by
110 CLC/TC 215 for information technology cabling, namely:
111 1) this and other parts of the EN 50174 series;
112 2) generic cabling design (EN 50173 series);
113 3) application dependent cabling design (e. g. EN 50098 series);
