Scope: This standard applies to the determination of power frequency withstand characteristics of porcelain and glass insulators used outdoors and exposed in polluted atmospheres for AC systems with the highest system voltage in the range of 1 kV to 765 kV. These tests cannot be directly applied to oil-coated insulators and special types of insulators (insulators with semi-conductive glaze or insulators covered with any organic insulating material).
