The purpose of this standard is to define the minimum requirements for water supply service plastic ball valves, including materials, design, testing, and shipping.

This standard describes plastic ball valves for water supply service. This standard covers threaded, union, fusion, or compression ended double- and single-seated nonmetallic ball valves for pressures 100 psi (689 kPa) and higher in sizes from ½-in. through 2-in. (13-mm through 50-mm) diameter for use in potable water systems with temperatures greater than 32°F (0°C) and less than 125°F (52°C).
