What is this standard about?
This document specifies a method to assess the thermal behaviour of cables arranged in bundles, for digital communications. A method is described to determine the temperature increase in cable bundles for certain remote powering currents as a basis to analyse the expected performance under several test arrangements described in standards dealing with the installation of cabling systems (e.g. [1] 1, [2]).
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.
The following test arrangements are considered:
c) free air;
d) cable tray;
e) conduits;
f) conduit with sealed ends.
Even though this document covers four-pair data grade cables, the same principles can be applied to other cable types.
