1 Scope
When used together with EN 50290 and EN 50289, this European Standard covers
cables for instrumentation, inter-connection of equipment and information technology
cabling applications.
Cables for information technology cabling systems, covered by this standard are
suitable for use in digital and analogue data systems meeting the requirements, for
example, of EN 50090-2-1, EN 50090-3-1, EN 50098-1, EN 50098-2 and EN 50173.
Instrumentation cables covered by this standard are suitable for connecting
instruments and control systems for analogue or digital signal transmission.
Unless otherwise specified, all cables covered by this standard may be subjected to
voltages greater than 50 V a.c or 75 V d.c. but not more than 300 V a.c. or 450 V d.c.
and shall meet the essential requirements of the low voltage directive. Due to current
limitation related to the conductor cross sectional area, they are not intended for direct
connection to mains electricity supply. The maximum current rating per conductor is
less than or equal to 175 mA unless otherwise specified in the relevant sectional
specification.
Cabling elements as defined in 4.3 of this standard may be incorporated in hybrid
construction cables together with coaxial or optical fibre cabling elements.
2 Normative references
This European Standard incorporates, by dated or undated reference, provisions from
other publications. These normative references are cited at the appropriate places in
the text and the cited publications are listed hereafter. For dated references,
subsequent amendments to or revisions of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated
references, the latest edition of the cited publication applies, together with any
amendments.

3 Definitions
For the purposes of this European Standard, the definitions given in EN 50290-1-2
and EN 50173 apply in addition to the following:
3.1
horizontal cable
cable suitable for connecting a floor distributor to a telecommunications outlet. It is
suitable for horizontal installation in ducts, trunking, suspended floors and ceiling
cavities
3.2
building backbone cable
cable suitable for connecting a building distributor to a floor distributor and may also
connect floor distributors in the same building. It is suitable for horizontal installation
or vertical installation between floors provided the cable has adequate mechanical
strength
NOTE Horizontal cable as defined in 3.1 may also be used as building backbone cable provided that it
has adequate mechanical strength and fire performance characteristics.
3.3
work area cable
a cable connecting the telecommunications outlet to the terminal equipment
3.4
patch cord cable
flexible cable unit or element with connector(s) used to establish connections on a
patch panel
NOTE Work area cables, as defined in 3.3, may be used as patch cord cable in any distributor of a
generic building wiring system to interconnect with equipment or to cross-connect between cabling
systems.

3.5
campus backbone cable
cable suitable for connecting a campus distributor to a building distributor(s). If used
outdoors or for direct burial, it shall have adequate protection for its operational
environment
3.6
equipment cable
a cable connecting equipment to a distributor
3.7
instrumentation cable
a multi-element cable suitable for connecting instruments and control systems. It may
incorporate screening, armouring and/or moisture barriers or environmental protection
layers
4 Requirements for cable construction
4.1 Conductors
Conductors may be solid or stranded.
The conductivity of copper conductors shall be in accordance with IEC 60028.
Stranded conductors shall consist of wires circular in section and assembled, without
insulation between them, by concentric stranding or bunching. As most of these
cables are used together with insulation displacement connecting devices (IDC), a
maximum of seven strands should be used.
The solid conductors or the individual wires of stranded conductor may be plain or
metal-coated.
There shall be no joint in the wire made subsequent to the last wire drawing operation.
Joints in individual strands
