Foreword
This document EN 50288-6-2:2013 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 standards
(dow) 2016-03-18
conflicting with this document have to
be withdrawn
This document supersedes EN 50288-6-2:2003.
2:2003:
- the addition of the Blank Detail Specification Annex;
- a number minor corrections and updating of references;
- the re-classification of ‘ELFEXT’ to ‘ACR-F’.
This Part 6-2 is to be read in conjunction to EN 50288-1.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.
This standard covers the Principle Elements of the Safety Objectives for Electrical Equipment
Designed for Use within Certain Voltage Limits (LVD - 2006/95/EC)

1 Scope
EN 50288-6-2 is a sectional specification for unscreened cables, characterised from 1 MHz up to
250 MHz, to be used as work area cables to connect a telecommunications outlet to the terminal
equipment and for patch cord cables to establish connections on a patch panel as defined in
EN 50173.
Work area and data centres cables may also be used as patch cord cables in any distributor of a
generic building wiring system to interconnect with equipment or to cross-connect between cabling
systems.
This sectional specification contains the electrical, mechanical, transmission and environmental
performance characteristics 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 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.
