This standard covers valves of nominal pressure (PN) designations 15 bar and 20 bar and nominal inlet sizes DN 40 to DN 65 for flanged ends and 1½ and 2½ for screwed ends

Selection and dimensioning of high-voltage insulators intended for use in polluted conditions - Insulators for d.c. systems Ingestion-build-133579 Manufacturers of cladding panels1 Scope This part of IEC 60815, which is a Technical Specification, 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 customer. It is applicable to: Glass and
