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 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.
