- Scope
- The method described in this standard is suitable for the measurement of the wettability of umbrella and umbrella cover materials for composite insulators used in overhead lines, substations and electrical equipment, and also for the measurement of wettability of porcelain insulators with or without coating. The measured value represents the wettability at the moment of its measurement. The purpose of this standard is to describe three methods that can be used to determine the wettability of insulators. The determination of the ability of water to wet the surface of an insulator may be used to evaluate the condition of the surface of an insulator in service, or as part of insulator testing in the laboratory.
