Specifies requirements for metal bodied and plastic bodied ball valves for installation between the reticulation water main and the property water meter in nominal sizes DN 15, DN 20, DN 25, DN 32, DN 40, and DN 50.

This Standard specifies requirements for metal-bodied and plastic-bodied ball valves for installation between the reticulation water main and the property water meter in nominal sizes DN 15, DN 20, DN 25, DN 32, DN 40 and DN 50, with the valve operating at continuous working pressures not exceeding 1.6 Mpa, and continuous operating temperatures not exceeding 60°C.This Standard describes the service connection ball valve, service connection termination ball valve and its protection cover and the right angle meter assembly ball valve. It also covers the minimum requirements for health and safety and the protection of the environment.Means for demonstrating compliance with this Standard are given in Appendix A.
