Building valves. Manually operated copper alloy and stainless steel ball valves for potable water supply in buildings. Tests and requirements Ingestion-build-223009 who have taken into consideration1 Scope This European standard applies primarily to copper alloy ball valves, dimensions DN 8 to DN 100, for potable water supply in buildings up to PN 10 and a distribution temperature of 65 C. Occasional excursions up to 90 C are permitted for a period of 1 h maximum. This standard applies also to ball valves in combination with other components in the same body. This standard specifies: the requirements of the materials and the design of ball
