scope:

This standard encompasses the design and performance requirements for right angle and straightaway hose valves for use in aboveground standpipe systems.

This standard has been based on NPS (Nominal Pipe Size) 1-1/2 and 2-1/2 in (DN 40 and DN 65 mm) common sizes. Other sizes may be considered for certification on case-by-case basis.

Hose valves considered under this standard may be designed with horizontal, bib-nosed, oblique, or right angle body patterns.

This standard encompasses traditional hose valves, pressure restricting hose valves, and pressure reducing hose valves. Definitions of the valves can be found in section 1.9.

Note: Hose valves with pressure reducing features are not intended to replace the pressure reducing valve that sets the water supply pressure for combined systems that supply water to the sprinkler system and the standpipe system.

The minimum rated working pressure for hose valves evaluated using this standard is 175 psi (1205 kPa).

Purpose

This standard states testing and certification requirements for angle and straightaway hose valves for use in aboveground standpipe systems, hose cabinets, and in fire pump discharge lines with playpipes.

Testing and certification criteria may include performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a surveillance audit program.
