本欧洲标准规定了评估受污染流体引发和维护的电弧的电缆绝缘行为的方法。 本欧洲标准应与EN 3475-100一起使用。 这个测试的主要目的是: - 以受控的方式产生连续的故障影响，这些故障影响代表典型的电缆束受损并受到含水流体污染时在使用中可能出现的影响，从而在电缆之间发生电弧; - 检查绝缘的能力以跟踪将电弧传播到电源。 该测试最初为115 Vac网络定义，也为230 Vac网络提供条件。除非产品标准中另有规定，否则只能满足115 Vac的条件。 针对相关电缆尺寸已经规定了六（6）级预期故障电流（见第7章）。普遍认为，较大的尺寸不需要评估，因为在低线路阻抗时短路现象占主导地位。 除非技术/产品标准尺寸002,006和020电缆中另有规定，否则应评估电缆。

This European Standard specifies a method for appraising the behaviour of cable insulation subjected to an electric arc initiated and maintained by a contaminating fluid. This European 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 may occur in service when a typical cable bundle is damaged and subjected to aqueous fluid contamination such that electrical arcing occurs between cables; - 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. Unless otherwise specified in product standard, only 115 Vac conditions shall be satisfied. Six (6) levels of prospective fault current have been specified for concerned cable sizes (see Clause 7). It is generally agreed that larger sizes need not be assessed since the short-circuit phenomenon becomes dominant at low line impedances. Unless otherwise specified in the technical/product standard sizes 002, 006 and 020 cable shall be assessed.
