Foreword
This document (EN 50288-1:2013) has been prepared by CLC/SC 46XC "Multicore, Multipair
and Quad Data communication cables," of CLC/TC 46X, "Communication cables".
The following dates are fixed:
• latest date by which this document has
(dop) 2014-03-18
to be implemented at national level by
publication of an identical national standard
or by endorsement
• latest date by which the national
(dow) 2016-03-18
standards conflicting with this document

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 and the sectional
specification standards in the EN 50288 series 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.
Unless otherwise specified, all cables covered by this European 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 as stipulated in Table
B.1 unless otherwise specified in the relevant sectional specification. IDCs are only designed
for copper or metal coated copper.
Cabling elements as defined in 4.3 of this European Standard may be incorporated in hybrid
construction cables together with coaxial or optical fibre cabling elements.

4 Requirements for cable construction
4.1 Conductors
Conductors are to be solid or stranded copper as specified in the relevant EN 50288 sectional
specification.
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 of a stranded copper inner conductor shall be cold pressure welded,
brazed or silver soldered using a non acid flux such that the strand diameter shall not be increased.
No joint in an individual strand shall be within 0,3 m of a joint in any other individual strand.
The nominal conductor diameter is given in the relevant sectional specification. Other
diameters or stranded conductors are to be agreed between manufacturer and purchaser and
specified in Annex B of the relevant sectional specification.
4.2 Insulation
The choice of the insulating material shall take into account electrical and environmental
requirements.
The insulation material(s) shall meet the requirements of the relevant part or parts of
EN 50290-2, or otherwise as detailed in the relevant 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 EN 60811-201.
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
EN 50289-3-17. When not used with IDC termination, it shall be possible to strip the
insulation from the conductor easily and without visible damage to the conductor, its coating,
or the insulation remaining on the conductor.
4.3 Cable elements
The cable element is
- a single insulated wire, or
- a pair consisting of two insulated conductors twisted together and designa
