Artificial pollution tests on high-voltage ceramic and glass insulators to be used on d.c. systems Ingestion-build-224916 The methods specified by the1 Scope This technical specification is applicable for the determination of the d. c. withstand characteristics of ceramic and glass insulators to be used outdoors and exposed to polluted atmospheres, on d. c. systems with the highest voltage of the system greater than 1 000 V. These tests are not applicable to polymeric insulators, to greased insulators or to special types of insulators (e. g. insulators with semiconducting glaze or covered with any
