This standard determines the ability of insulating materials to produce electrolytic corrosionon metals being in contact with them under the influence of electric stress, high humidity andelevated temperature.The effect of electrolytic corrosion is assessed in one test by using consecutively twomethods:• visual semi-quantitative method consisting in comparing visually the corrosion appearingon the anode and cathode metal strips, with those given in the reference figures.This method consists of the direct visual assessment of the degree of corrosion of twocopper strips, acting as anode and cathode respectively, placed in contact with the testedinsulating mat
