Is applicable for the determination of the power frequency
withstand characteristics of ceramic and glass insulators to be
used outdoors and exposed to polluted atmospheres, on a.c. systems
with the highest voltage of the system ranging from 1 000 V up to
765 kV.
These tests are not directly applicable to greased insulators or to
special types of insulators (insulators with conductive glaze or
covered with any organic insulating material).
