Work area 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. The electrical, mechanical, transmission and environmental performance characteristics of he screened cables, related to their reference test methods, are detailed. This sectional specification is to be read in conjunction with EN 50288-1 which contains the essential provisions for its application. 2Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications.
