IEC TS 62073:2016.Guidance on the measurement of hydrophobicity of insulator surfaces. The wetting properties of a surface by water are commonly described by the terms hydrophobic(or hydrophobicity) and hydrophilic (or hydrophilicity). A hydrophobic surface is water-repellent, while a surface that is easily wetted by water is hydrophilic. The wetting phenomenon of a surface is complex and many different parameters can...
