European foreword
This document (EN 50288-12-1:2017) has been prepared by WG 2 of 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) 2018-05-30
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2020-05-30
standards conflicting with this document
have to be withdrawn
This document has been prepared under a mandate given to CENELEC by the European Commission and
the European Free Trade Association.
EN 50288-12-1 is meant to be read in conjunction with EN 50288-1:2013.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
1 Scope
EN 50288-12-1 is a sectional specification for screened cables, characterised up to 2 000 MHz, to be used in
horizontal and building backbone wiring for information technology, generic-cabling systems.
This sectional specification contains the electrical, mechanical, transmission and environmental performance
characteristics and requirements of the cables when tested in accordance with the referenced test methods.
This sectional specification is to be read in conjunction with EN 50288-1, which contains the essential
provisions for its application.
The cables covered in this sectional specification are intended to operate with voltages and currents normally
encountered in communications systems. These cables are not intended to be used in conjunction with low
impedance sources, for example the electrical power supplies of public utility mains.

appropriate. The colours shall meet the requirements of 4.4 of EN 50288-1:2013.
4.5 Screening of cabling elements
Where appropriate, screening of the cabling elements shall be applied in accordance with 4.5 of
EN 50288-1:2013. When a braid is used the minimum braid coverage (for mechanical purposes) shall be
60 %. When a foil and braid are used the minimum braid coverage (for mechanical purposes) shall be 30 %.
Coverage is defined in EN 50290-2-1.
4.6 Cable make-up
The cable elements shall be laid up in concentric layer(s) or units to form the cable core.
4.7 Filling compound
Not applicable.
4.8 Interstitial fillers
Where fillers are used they shall meet the requirements of 4.8 of EN 50288-1:2013.
4.9 Screening of the cable core
The screening of the cable core shall be applied in accordance with 4.9 of EN 50288-1:2013. When a braid is
used the minimum braid coverage (for mechanical purposes) shall be 60 %. When a foil and braid are used,
and/or where a foil is used over elements / the core, the minimum braid coverage (for mechanical purposes)
shall be 30 %. Coverage is defined in EN 50290-2-1.
4.10 Moisture barriers
Not applicable.
4.11 Wrapping layers
Where wrapping layers are used they shall be in accordance with 4.11 of EN 50288-1:2013.
4.12 Sheath
The sheath shall be of a suitable material according to the appropriate part of EN 50290-2.
