Application Summary AI generated
This standard provides a test method for measuring the contact angle of water droplets on insulator surfaces to assess their hydrophobicity. It is applied in the electrical power industry for evaluating the surface condition of ceramic, glass, and composite insulators used in high-voltage transmission lines. The guidance helps determine whether insulator surfaces have degraded or lost their water-repellent properties, which is critical for predicting pollution flashover performance.
