scope:

Automatic water control valves are most commonly used to control the flow of water to various fire protection sprinkler systems. They are used in sprinkler systems such as deluge, preaction, refrigerated area, and on-off multicycle sprinkler systems. Therefore, valves used for these applications must meet the requirements of this standard, as well as, at minimum.

Although not addressed in this standard, automatic water control valves may be configured to control the flow to water spray systems, open and closed head foam water sprinkler systems and other special purpose systems. Certain designs of automatic water control valves are also utilized on the discharge of fire pumps for pressure relief, pressure reducing, and pump suction pressure regulating purposes.

Purpose

This standard states testing and certification requirements for automatic water control valves.

Testing and certification criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a surveillance program.
