30、NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover single- and multiple-jacketed lined re hose with or 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, 6

31、5, 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 covered hose judged equivalent to multiple-jacketed hose is intended for service test pressures of 200, 300, or 400 p

32、sig (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 similar places. They are not intended for hard usage nor where the hose will be subjected to chang on rough or sharp sur

33、faces. 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 protection against wear afforded by the extra woven jacket or cover. 1.3 The products covered by these requirements are inten

34、ded 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, Nozzles, and Fire Hose Appliances, NFPA 1962. 2 Units of Measurement 2.1 Values stated without parentheses are the req

35、uirement. Values in parentheses are explanatory or approximate information. 3 Undated References 3.1 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. 4 Glossary 4.1 For the pur

36、pose of this standard, the following denitions apply. 4.2 EXPANSION RING A ring that expands against the hose lining, forcing the hose tightly against the coupling. 4.3 FILLER THREADS The threads or yarns of the jacket or reinforcement that are helically wound throughout the length of the hose at ap

37、proximately right angles to the warp threads. 4.4 HOSE ASSEMBLY Hose furnished with couplings attached to each end. 4.5 MULTIPLE-JACKETED HOSE Hose having two or more woven jackets or a covered hose that complies with all of the performance tests in this standard for multiple-jacketed hose. See 6.3.

38、 AUGUST 13, 2018 LINED FIRE HOSE AND HOSE ASSEMBLIES - UL 19 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4.6 PROOF PRESSURE A specied pressure applied to new hose to indicate its acceptability at intended maximum normal highest operatin

39、g pressures. 4.7 SERVICE TEST PRESSURE The pressure to which the hose is periodically tested to determine that it can remain in service. The service test pressure is at least 10 percent greater than the maximum normal highest operating pressure. 4.8 WARP THREADS The threads or yarns of the jacket or

40、 reinforcement that run lengthwise to the hose. CONSTRUCTION 5 Internal Diameter 5.1 Hose shall have an internal diameter of not less than the trade size of the hose. 5.2 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 diame

41、ter, 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 the lap joint. 5.3 To determine the internal diameter, the end of the hose is to be cut square and the tapered plug gauge inserted in th

42、e 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 as the internal diameter of the hose. 6 Jacket and Inner Reinforcements 6.1 A jacket shall be evenly and rmly woven, and free from visib

43、le 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 the ller threads shall be tucked under the warp threads. 6.2 A jacket shall be seamless and shall have the llers woven around the hose

44、throughout its length and the warps interwoven with the llers. A jacket may be made with a cover over the woven jacket. 6.3 Hose having a woven jacket or hose having an inner reinforcement and a protective cover may be considered equivalent to multiple-jacketed hose if it complies with the applicabl

45、e performance requirements specied in this standard. AUGUST 13, 2018 LINED FIRE HOSE AND HOSE ASSEMBLIES - UL 19 8UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 7 Lining 7.1 A lining shall be of uniform thickness and free from pitting or ot

46、her irregularities or imperfections and shall comply with the applicable test requirements specied in Sections 24 27. 8 Cover 8.1 A cover shall be of uniform thickness and free from pitting, blisters, or other imperfections that would impair its intended use, and shall comply with the applicable tes

47、t requirements in Sections 24 26. 8.2 A cover may have intentional pricking, ribs, corrugations, or a wrapped nish. 9 Coatings and Treatments 9.1 Hose may have jackets with treatments or coatings if the hose complies with the applicable performance requirements in this standard. 10 Couplings 10.1 Th

48、e couplings of hose assemblies shall be made from metals having the strength and other characteristics necessary to comply with the applicable performance requirements in this standard. 10.2 A metal used in the construction of any part shall have corrosion-resistant properties equivalent to those of

49、 high-strength yellow brass, UNS No. C86500 in the Standard Specication for Copper Alloys in Ingot form, ASTM B30 and in the Standard Specication for Copper Alloy Sand Castings for General Applications, ASTM B584. 10.3 To determine if a metal has the properties mentioned in 10.2, it shall comply with the requirements of the Salt-Spray Corrosion Test, Section 32. 10.4 A copper-alloy part containing more than 15 percent zinc shall comply with the requirements of
