The purpose of this standard is to specify the various types and classes of wet-barrel fire hydrants that are suitable for use in fire-protection services in areas where the climate is mild and freezing temperatures do not occur. A wet-barrel hydrant is designed with one or more valve openings located above the ground line. Under normal operating conditions, the entire interior of the hydrant is subjected to water pressure at all times. Each outlet nozzle is equipped with an independent, compression-type valve that operates either with or against the pressure to control the discharge from that particular outlet.

This standard provides guidance for purchasing and receiving wet-barrel fire hydrants, as well as for inspecting and testing these hydrants. It is important to note that the stipulations of this standard only apply when this document has been referenced and only to wet-barrel fire hydrants used in water-supply services.

In conclusion, this standard is crucial for ensuring the safety and effectiveness of fire-protection services in areas where mild climates and freezing temperatures are prevalent. By specifying the appropriate types and classes of wet-barrel fire hydrants, it helps to ensure that fire fighters have access to reliable and efficient equipment when responding to emergencies.
