International cable fire test

To achieve typical flame retardancy for cables required by the most important international cable fire test (lEC 60332-3-24, Tests on electrical cables imder fire conditions - Part 3-24 Test for vertical flame spread of vertically-mounted bunched wires or cables) demands a high loading of a mineral FR filler such as ATH. 65wt% of ATH with 35% of a suitable polymer like EVA must often be used for cable jackets. A similar compound of EVA (with 28% VA content) with ATH and 5% of a nanocomposite can pass the same test. It was found that the ATH could be reduced to only 45% of the composition. The reduction in the total amount of the fillers results in improved mechanical and rheological properties of typical EVA-based cable compoimds. The char formed is... 

Cable compounds must be flame retardant to achieve a low flame spread, defined by the widely used international cable fire test (DEC 60332-3-24) [42]. A compound containing...

Another recent development focuses on fire induced cable failures and circuit faults, which are broadly discussed on an international level (USNRC 2005). In this context, a cable failure mode and effect analysis (FMEA) for all the PSA related cables has been developed (Herb Piljugin 2008) and tested for...
