Anotácia textu normy IEC 61156-5-ed.3.0-RLV :
IEC 61156-5:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61156-5:2020 describes the cables intended primarily for horizontal floor wiring as defined in ISO/IEC 11801. It covers cable designs comprising individually screened, common screened and unscreened pairs or quads. The transmission characteristics and the frequency range of the cables are specified at 20 °C. The cables covered by this document are intended to operate with voltages and currents normally encountered in communication systems Those cables are intended to be used to support the delivery of low voltage remote powering applications such as IEEE 802.3af (Power over Ethernet) or further developments for example according to IEEE 802.3at or IEEE 802.3bt. This third edition cancels and replaces the second edition published in 2009 and Amendment 1:2012. This edition includes the following significant technical changes with respect to the previous edition - additional balance levels with respect to MICE implementation by certain cabling specifications; - reference to current standards and technical reports with respect to measurement techniques and remote powering.
