PD IEC TS 60815 4 is a Technical Specification, that is applicable as first approach for the determination of the required d. c. Unified Specific Creepage Distance for insulators with respect to pollution. To avoid excessive over or under design, existing operation experience should be compared and eventually additional appropriate tests may be performed by agreement between supplier and
