33、r without couplings attached, in the trade sizes of 1-1/2, 1-3/4, 2, 2-1/2, 3, 3-1/2, 4, 5, and 6 inch (38, 45, 51, 65, 76, 89, 102, 127, and 152 mm nominal ID). Single-jacketed hose is intended for service test pressures of 150, 200, or 250 psig (1035, 1380, or 1725 kPa). Multiple-jacketed hose or
34、covered hose judged equivalent to multiple-jacketed hose is intended for service test pressures of 200, 300, or 400 psig (1380, 2070, or 2760 kPa). 1.2 These products are intended for municipal and industrial re protection purposes. Single-jacketed hose is for use at re hydrants, standpipes, and sim
35、ilar places. They are not intended for hard usage nor where the hose will be subjected to chang on rough or sharp surfaces. Multiple-jacketed hose or covered hose judged equivalent to multiple-jacketed hose are for use on pumpers and in places where service conditions require the additional protecti
36、on against wear afforded by the extra woven jacket or cover. 1.3 The products covered by these requirements are intended to be periodically inspected and maintained while in service, as outlined in the Standard for the Care, Use, Inspection, Service Testing and Replacement of Fire Hose, Couplings, N
37、ozzles, and Fire Hose Appliances, NFPA 1962. 2 General 2.1 Units of measurement 2.1.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.2 Undated references 2.2.1 Any undated reference to a code or standard appearing in the req
38、uirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 3 Glossary 3.1 For the purpose of this standard, the following denitions apply. 3.2 EXPANSION RING A ring that expands against the hose lining, forcing the hose tightly against the coupling.
39、3.3 FILLER THREADS The threads or yarns of the jacket or reinforcement that are helically wound throughout the length of the hose at approximately right angles to the warp threads. 3.4 HOSE ASSEMBLY Hose furnished with couplings attached to each end. 3.5 MULTIPLE-JACKETED HOSE Hose having two or mor
40、e woven jackets or a covered hose that complies with all of the performance tests in this standard for multiple-jacketed hose. See 5.3. 3.6 PROOF PRESSURE A specied pressure applied to new hose to indicate its acceptability at intended maximum normal highest operating pressures. OCTOBER 25, 2013 LIN
41、ED FIRE HOSE AND HOSE ASSEMBLIES - UL 19 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 3.7 SERVICE TEST PRESSURE The pressure to which the hose is periodically tested to determine that it can remain in service. The service test pressure i
42、s at least 10 percent greater than the maximum normal highest operating pressure. 3.8 WARP THREADS The threads or yarns of the jacket or reinforcement that run lengthwise to the hose. CONSTRUCTION 4 Internal Diameter 4.1 Hose shall have an internal diameter of not less than the trade size of the hos
43、e. 4.2 A tapered plug gauge having a taper of 3/8 inch per foot (31.2 mm/m) marked to indicate variations of 1/64 inch (0.4 mm) in diameter, is to be used to measure the internal diameter. If the lining of the hose has a lap joint, the tapered plug gauge is to be provided with a slot to accommodate
44、the lap joint. 4.3 To determine the internal diameter, the end of the hose is to be cut square and the tapered plug gauge inserted in the hose sample until a close t is obtained without forcing. The diameter of the gauge at the end of the sample, to the nearest 1/64 inch (0.4 mm), is to be recorded
45、as the internal diameter of the hose. 5 Jacket and Inner Reinforcements 5.1 A jacket shall be evenly and rmly woven, and free from visible defects, thread knots, lumps, and irregularities of twist provided that they would not impair its intended use. The threads shall be continuous, and any knots in
46、 the ller threads shall be tucked under the warp threads. 5.2 A jacket shall be seamless and shall have the llers woven around the hose throughout its length and the warps interwoven with the llers. A jacket may be made with a cover over the woven jacket. 5.3 Hose having a woven jacket or hose havin
47、g an inner reinforcement and a protective cover may be considered equivalent to multiple-jacketed hose if it complies with the applicable performance requirements specied in this standard.
