Building valves - Manually operated copper alloy and stainless steel ball valves for potable water supply in buildings - Tests and requirements
This document applies primarily to copper alloy and stainless steel ball valves with dimensions DN 6 to DN 100, for installations in buildings for potable water supply up to PN16 and a maximum distribution temperature of 65 °C. Occasional excursions up to 90 °C are permitted for a period of 1 h maximum.
The ball valves are classified by their nominal pressure being either PN10 or PN16.
This document specifies:
- the requirements of the materials and the design of ball valves;
- the mechanical, hydraulic and acoustic requirements of ball valves;
- the test methods to verify the requirements of ball valves;
- the marking requirements of ball valves.
