Description
Determines the ability of insulating materials to produce electrolytic corrosion on metals being in contact with them under the influence of electric stress, high humidity and elevated temperature. The effect of electrolytic corrosion is assessed in one test by using consecutively two methods: - visual semi-quantitative method consisting in comparing visually the corrosion appearing on 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 two copper strips, acting as anode and cathode respectively, placed in contact with the tested insulating material under a d.c. potential difference at specified environmental conditions. The degree of corrosion is assessed by visually comparing the corrosion marks on the anode and cathode metal strips with those shown in the reference figures; - quantitative method, which involves the tensile strength measurement, carried out on the same anode and cathode metal strips after visual inspection.

ATTENTION: Belgian registered standards (NBN EN or NBN HD) are generally only available in English or French. Only the cover page is translated and the document itself is in English or in French.

Very important notice: 98% of the text of the NBN EN 55XXX, NBN EN 6XXXX comes from the IEC text which is NOT included. This text can be ordered here: IEC 60426:2007. For the series NBN EN 50XXX, the standards are however complete.
