DESCRIPTION
BS IEC 61156-1-4:2018
This standard BS IEC 61156-1-4:2018 Multicore and symmetrical pair/quad cables for digital communications is classified in these ICS categories:
- 33.120.20 Wires and symmetrical cables
It is only intended to provide guidance to assess the thermal behaviour of cables for digital communications in reference environmental conditions and arrangements. It is therefore not intended to become a type of test method.
This first edition cancels and replaces IEC PAS 61156-1-4, published in 2010. This edition includes the following significant technical changes with respect to the previous edition:
a) Several test arrangements are considered;
b) The mathematical approach was revised.
