FOREWORD
1 Scope
2 Normative references
3 Terms, definitions, symbols, units and abbreviated
terms
4 The testing of bundled cables
5 The temperature as a function of the current load
in conductors of bundled cables in hexagonal densest
packing structure
6 Assessing already deployed cable systems
7 The higher performing data grade cables
8 The heat dissipation on heated and bundled cables
9 The heat dissipation in a heated conductor, pair or
cable which has to be taken into account
10 Thermodynamic considerations for a combined
experimental and mathematical solution of the
heating problem
IEC/PAS 61156-1-4:2010(E) is covering exclusively four-pair data grade cables and is intended to provide a test method for the determination of the maximum attained conductor temperatures which occur due to the deployment of the IEEE protocol for PoE /PoEP. It gives as well the required background information about the thermodynamic behaviour of such bundled cables, if they are located in areas with restricted heat dissipation, a reality which occurs in every installation situation. However, only the basic principles are given, as the rigorous application and solution of these problems fall into the relevant cabling standards.
