1 Scope
When used together with EN 50290 and EN 50289 this European standard covers cables for
instrumentation, 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,
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.
When subjected to voltages greater than 50 V a.c or 75 V d.c. but less than 500 V a.c. or
750 V d.c., cables covered by this standard shall meet the essential requirements of the LVD.
Due to current limitation related to the conductor cross sectional area, they are not intended for
direct connection to mains electricity supply or other low impedance sources.
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.

3 Definitions
For the purposes of this European Standard, the definitions given in EN 50290-1-2 and the
following apply:
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 cables as defined in 3.1 may also be used as building backbone cables provided that they have
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
multi-element copper cable suitable for connecting instruments and control systems. It may
incorporate screening, armouring and/or moisture or environmental protection layers
4 Requirements for cable construction
4.1 Conductor
The conductor shall be either solid or stranded annealed copper. The conductivity of the copper
shall be in accordance with IEC 60028.
Joints in the drawn conductors of finished cables are not permitted.
The stranded conductor shall consist of wires circular in section and assembled without
insulation between them by concentric stranding or bunching.
The individual wires of the solid or stranded conductor may be plain or metal-coated.
4.2 Insulation
The insulation material(s) shall meet the requirements of the relevant part or parts of
EN 50290-2 or otherwise as detailed in the appropriate sectional specification. Conductor
insulation shall be composed of one or more suitable dielectric materials. The insulation may be
solid, cellular or composite (e.g. foam skin).
The insulation shall be continuous, having a thickness as uniform as possible. When required,
the thickness of the insulation shall be measured in accordance with the method specified in 8.1
of EN 60811-1-1:1995.
The insulation shall be applied to fit closely to the conductor. When required, the stripping
properties of the insulation shall be checked in accordance with the method specified in 3.4 of
IEC 60189-1:1986.
- 7 - EN 50288-1:2001
4.3 Cable elements
The cable element is:
− a single insulated wire, or
− a pair consisting of two insulated conductors twisted together and designated wire “a” and
wire “b”, or
− a triple consisting of three insulated conductors twisted together and designated wire “a”,
wire “b” and wire “c” in order of rotation, or
− a quad consisting of four insulated conductors twisted together and designated wire “a”,
wire “c”, wire “b” and wire “d” in order of rotation. Wires “a” and “b” form pair 1 and wires
“c” and “d” form pair 2.
The choice of the maximum average lay length of the cable elements in the finished cable shall
take into account the transmission requirements, handling performance and identification.
