    Abstract - (Show below) - (Hide below)

    Indicates relative resistance of solid electrical insulating materials to tracking for voltages up to 600 V when the surface is exposed under electric stress to water with the addition of contaminants. Also considers erosion of materials which do not track at the highest test voltage.
