Standard Specification for Fire Hose Nozzles
ABSTRACT
This specification covers the design, manufacture, and testing of fire hose nozzles intended for use with sea water or fresh water either in straight stream or adjustable spray patterns. Marine fire hose nozzles may be classified into four general construction types, as follows: Type I; Type II; Type III; and Type IV. Nozzle types may be subdivided into three general classes, as follows: Class I; Class II; and Class III. Classes may be subdivided into two general sizes. Tensile strength, ultimate elongation, tensile set test, compression set test, accelerated aging test, aging exposure, ultraviolet light-water exposure, discharge calibration test, flow pattern test, flushing test, control tests, corrosion exposure, high temperature test, low temperature test, rough usage test, leakage test, hydrostatic pressure test, operator protection test, and horizontal distance shall be performed to conform with specified requirements.
SCOPE
1.1 This specification covers the design, manufacture, and testing of fire hose nozzles intended for use with sea water or fresh water either in straight stream or adjustable spray patterns.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3.1.3 constant flow rate spray nozzle, n—an adjustable pattern nozzle in which the flow is delivered at a designed nozzle pressure.
At the rated pressure, the nozzle will deliver a constant flow rate from straight stream through a wide angle pattern. This is
accomplished by maintaining a constant orifice size during flow pattern adjustment.
3.1.4 constant pressure (automatic) spray nozzle, n—an adjustable pattern nozzle in which the pressure remains constant through
a range of flows rates. The constant pressure provides the velocity for an effective stream reach at various flow rates. This is
accomplished by means of a pressure-activated, self-adjusting orifice baffle.
3.1.5 constant/select flow rate feature, n—a nozzle feature that allows on-site adjustment of the orifice to change the flow rate to
a predetermined value. The flow rate remains constant throughout the range of pattern selection from straight stream to wide angle
spray.
3.1.6 free swivel coupling, n—a coupling between the nozzle and hose or between halves of a break-apart nozzle that is capable
of being turned readily by hand; that is, a spanner wrench is not required to tighten the coupling to prevent leakage.
3.1.7 flush, n—a feature in a nozzle that allows the orifice to be opened so that small debris that might otherwise be trapped in
