IEC 61156-3 Ed. 3.0 en:2008 ✓ Most Recent

IEC 61156-3:2008(E) defines individually screened, common overall core screen and unscreened pairs or quads in cables for work area wiring. These cables are suitable for the various communication systems for which the reference is given in the relevant detail specification. The cables covered by this sectional specification are intended to operate with voltages and currents normally adopted for communication systems. These cables should not be connected to low impedance sources, for example, the public mains electricity supply. The cables are specifically intended for work area wiring as defined in ISO/IEC 11801. This third edition cancels and replaces the second edition published in 2003. This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition:
a) new requirements for new cables Cat3, and Cat5 applications;
b) a better numbering in order to take into account the generic specification.
