1 Scope
This sectional specification covers screened cables, characterised from 1 MHz up to 1 000 MHz, to be used
to construct cords for use in cabling specified in the EN 50173 series of standards.
The premises-specific cabling standards of the EN 50173 series reference the D1 requirements of this
specification for the cable used within cords of the “reference implementations” of those standards. The
alternative D2 requirements of this specification may be used to produce cords for other implementations and
applications including the direct connection of equipment in data centres.
This sectional specification contains the electrical, mechanical, transmission and environmental performance
characteristics and requirement of the cables when tested in accordance with the referenced test methods.
This sectional specification should 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 communication systems. These cables are not intended to be used in conjunction with low
impedance sources, for example, the electric power supplies of public utility mains.

For the purposes of this document, the terms and definitions given in EN 50288-1 and the following apply.
3.1.1
screening of cable
a cable is considered screened when the cable core is covered by a continuous conductive layer forming part
of the shielding and bonding system of the cabling system
Note 1 to entry: DC continuity has to be given and minimum shielding requirements have to be met.
3.2 Symbols and abbreviations
For the purposes of this document, the following abbreviations apply.
