EN 3475-603:2002

Aerospace series - Cables, electrical, aircraft use - Test methods - Part 603: Resistance to wet arc tracking

Scope

This standard specifies a method for appraising the behaviour of cable insulation subjected to an electric arc initiated by a contaminating fluid.
This standard shall be used together with EN 3475-100.
The primary aim of this test is to produce, in a controlled fashion, failure effects which are representative of those which may occur in service when a typical cable bundle is damaged and subjected to aqueous fluid contamination such that electrical arcing occurs, both between cables and between cables and conductive structure.
Six levels of prospective fault current have been specified for cable sizes 26 to 10.
Individual product standards shall require at least sizes 24, 20, 14 cable to be assessed.
