適用范圍：This standard specifies a method for appraising the behaviour of cable insulation subjected to an electric arcinitiated and maintained 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, continuous failure effects which are representative of those which mayoccur in service when a typical cable bundle is damaged and subjected to aqueous fluid contaminationsuch that electrical arcing occurs, between cables; and? to examine the aptitude of the insulation to track, to propagate electric arc to the electrical origin.Originally defined for 115 Vac network, this test also proposes conditions for 230 Vac network. Unlessotherwise specified in product standard, only 115 Vac conditions shall be satisfied.Six levels of prospective fault current have been specified for concerned cable sizes (see Clause 7). It isgenerally agreed that larger sizes need not be assessed since the short-circuit phenomenon becomesdominant at low line impedances.Unless otherwise specified in the technical/product standard sizes 002, 006 and 020 cable shall be assessed.
