Summary: This standard applies to insulating materials in electrical stress, high humidity, high temperature metal contact under the influence of electrolytic corrosion under the conditions set side. An electrolytic corrosion assessment tests are two methods by continuous trials were evaluated. a) full mesh side semi-definite method by comparing the positive and negative metal boxes metal boxes corrosion appearance (given by reference to FIG) for judgment. Test is two boxes with copper as the anode and cathode, respectively, put them in contact with the material being tested, the required environmental conditions plus DC potentiometer, a direct head -side comparison of the positive signs of corrosion and metal case with a given the reference diagram to evaluate the degree of corrosion. b) quantitative method is to use the same visual method after the positive and negative metal boxes metal boxes for tensile strength tests. Electrolytic corrosion assessment Another test is a quantitative measurement of the tensile strength of Tong line, see Appendix C.

Foreword

This standard is identical with IEC 60426.2007 (2nd edition) "Determination of electrically insulating material with insulating materials caused by electrolytic corrosion test Test method "(in English). This standard is technically and IEC 60426.2007 (2nd edition) agreement, only made the following editorial changes. --- Remove IEC 60426.2007 Foreword and Introduction, increasing the national standards foreword; "." --- With a decimal point instead of a comma as the decimal point, ""; --- With "℃" instead of "K"; --- In the second chapter of normative references, the IEC 60454-2 rewritten as GB/T 20631.2-2006. This standard replaces GB/T 10582-1989 "Standard Test Method for Determination of electrolytic corrosion caused by insulating materials." This standard compared with GB/T 10582-1989 main changes are as follows. --- Increasing the normative references; --- Increasing the terms and definitions; --- Remove the original meaning of the standard (GB/T 10582-1989 Chapter 2); --- The visual semi-quantitative and quantitative methods (tensile strength test) to replace the original combination of the standard visual method, and to increase the corrosion level judgment Plus the tensile strength; --- Remove the insulation resistance of the original standard method (GB/T 10582-1989 Chapter 5); --- Pickling solution instead of the original standard requirements; --- With (120 ± 5) V DC power supply instead of the original standard of (100 ± 5) V DC power supply; --- Corrosion level representation has changed.

1 Scope

This standard applies to insulating materials in electrical stress, high humidity, high temperatures and affect the determination of the lower metal contact conditions of electrolytic corrosion. An experimental evaluation of the degree of electrolytic corrosion is assessed by two methods of continuous tests. a) visual semiquantitative method by comparing the positive electrode and the negative electrode metallic foil metal foil corrosion appearance (given with reference to FIG) judgment of. Test is two copper foil tape were used as positive and negative electrodes, put them in contact with the material being tested, at a predetermined ring Under ambient conditions plus DC potentiometer, direct visual comparison of the positive signs of corrosion and metal foil tape given with reference to FIG been evaluated The degree of corrosion. b) quantitative method is to use the same visual method after the positive electrode and the negative electrode metallic foil metal foil tensile strength test. Another test is to assess the degree of electrolytic corrosion of copper quantitative measurement of tensile strength, see Appendix C.
