ASTM F1546 Standard Specification for Fire Hose Nozzles
ASTM F1546 消防水龙头连接头标准规范

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.
