The measuring method applied depends on the bearing metal layer thickness

Artificial pollution tests on high-voltage ceramic and glass insulators to be used on a.c. systems Ingestion-build-93833 on the one hand1 Scope This International Standard 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 greater than 1 000 V. These tests are not directly applicable to polymeric insulators, to greased insulators or to special types of insulators (insulators with semiconducting glaze or
