19、 for use with re hose mounted on standpipe systems. 1.2 Requirements for the installation and use of spray nozzles used in standpipe systems are intended to be in accordance with the Standard for Standpipe, and Hose Systems, NFPA 14. 1.3 Nozzles covered by this Standard are intended to be inspected
20、and maintained in accordance with Standard for the Inspection, Care and Use of Fire Hose, Couplings and Nozzles and the Service Testing of Fire Hose, NFPA 1962, and the Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems, NFPA 25, when used in standpipe system
21、s. 1.4 Nozzles covered by this Standard are intended for use on: a) Class A common combustibles such as wood and paper, and B ammable liquid res; or b) Class A, B, and C, if suitable for use on electrically energized res. 2 Components 2.1 Except as indicated in 2.2, a component of a product covered
22、by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components generally used in the products covered by this standard. 2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristi
23、c not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic components are incomplete in const
24、ruction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions.

26、4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 5 Glossary 5.1 For the purpose of these requirements, the following denitions apply. 5.2 BASIC SPRAY NOZZLE An adjustable p
27、attern spray nozzle in which the rated ow is delivered at a designated nozzle pressure and pattern setting. Due to its basic design, as the pattern is changed from straight stream through a wide spray pattern, the ow rate will vary as well as the nozzle pressure due to variations in area of the ow p
28、ath. 5.3 CONSTANT FLOW (GALLONAGE) SPRAY NOZZLE An adjustable pattern nozzle in which the ow is delivered at a designed nozzle pressure. At the rated pressure the nozzle will deliver a constant gallonage from straight stream through a wide spray pattern. This is accomplished by maintaining a constan
29、t orice size during ow pattern adjustment. 5.4 CONSTANT PRESSURE (AUTOMATIC) SPRAY NOZZLE An adjustable pattern nozzle in which the pressure remains constant through a range of ows. The constant pressure provides the velocity for an effective stream reach at various ow rates. This is accomplished by
30、 means of a pressure-activated, self-adjusting orice. 5.5 CONSTANT/SELECT FLOW (GALLONAGE) SPRAY NOZZLE A nozzle with a feature that allows the operator to manually adjust the orice to change the ow rate to a predetermined ow. The ow remains constant throughout the range of pattern selection from st
31、raight stream to wide spray. 5.6 FLUSH/CLOGGING FEATURE A feature in a nozzle that allows the orice to be opened so that small debris (that might otherwise be trapped in the nozzle causing pattern disruptions and ow variation) can pass through. When the ush feature is engaged, the nozzle pressure ma

33、ive October 16, 2017 5.9 RATED OPERATING PRESSURE The pressure specied by the manufacturer at which a nozzle is designed to discharge the rated ow. 5.9 effective October 16, 2017 5.10 SPRAY NOZZLE/SPRAY NOZZLE ASSEMBLY A nozzle that has a water ow control feature that will provide both full discharg
34、e and ow shutoff. This control device may be a permanently mounted valve or a break-apart shutoff butt assembly.

36、wise specically ordered to t existing equipment. If the female ends are provided with threads other than those specied in NFPA 1963, there shall be a minimum of 2-1/2 threads. 6.2 The outer ends of all internal threads dened as American National Fire Hose Connection Screw Threads (also known as NST
37、and NS) shall be terminated by the blunt start or Higbee Cut on the full thread to facilitate coupling and to avoid crossing and mutilation of thread. 6.3 Each nozzle shall be provided with a resilient gasket tted in the recess in the nozzle. The gasket shall have dimensions in accordance with the S
38、tandard for Screw Threads and Gaskets for Fire Hose Connections, ANSI/NFPA 1963. Gaskets and washers shall not project into the waterway. 6.4 A nozzle shall have a nominal inlet size of 3/4 inch (19.1 mm) or larger with a rated ow of less than 350 gpm (1325 l/min) while discharging water at 100 psig
