Standard On Fire Hose
1961-1 Copyright © 2007 National Fire Protection Association. All Rights Reserved. NFPA 1961 Standard on Fire Hose 2007 Edition This edition of NFPA 1961, Standard vnFire Hose, was prepared by the Technical Committee on Fire Hose. It -was issued by the Scmdards Council on December 1, 2006, with an effective date of December 20, 2006, and supersedes all previous editions. This edition of NFPA 1961 was approved as an American National Standard on December 20, 2006. Origin and Development of NFPA 1961 Standards on fire hose for both industrial use and fire department use were among the earliest standards issued by NFPA, with the first standard issued in 1898. NFPA 196 was issued in 1934 as Standard Specification for Cotton Rubber -Lined Fire Hose for Public and Private Fire Department Use. That standard remained in existence until 1958, when the Fire Hose Committee was again constituted to update the requirements. A tentative standard was issued in 1958 and the official standard was issued in 1960 recognizingthe newer synthetic rrtaterials-that_were_being used-in-the-manufacnn c Yn of fire hose. Thf1 960 standard covered fire hose in the 1 in., in., 2 in., and 21/2 in. sizes for single or multiple jacket hose -and in,anckerfrose In the 1972 edition, the concept of singk jacket relay supply_hose-in-the ade sizes-ef-8-hs., 4 in., 41/2 in., 5 in., and 6 in. was introduced. In 1979 the standard was renumbered from NFPA 196 to NFPA 1961 to coincide with a general renumbering of the fire service standards. In the 1992 edition, the term "rack and reel hose" was changed to "occupant use hose;" the require- ments for forestry hose were updated, and the requirements for suction hose were added. The 1997 edition was a reconfirmation of the 1992 edition. The 2002 edition was completely revised'to'conform to the Manual ofStyle for ArPPA Techni- cal Committee Documents, to clean up ambiguous language, and to clarify the requirements. Procurement -related issues-wc,t, detetezf from -the requirements of the document, and an equivalency statement and a formal retroactivity statement were. added. The minimum trade size requirement was dropped for all but supply hose. The requirements for specific lengths were changed to only require a tolerance on the stated nominal length. Positive pressure requirements for hard suction hose were deleted. A cold resistance test was added for all hose. Specific requirements were added to test the hose for abrasion resistance, heat resistance, water resistance, degradation from repeated bending, and degradation from alternating pressures. The flexibility and compressibility test method for forestry hose previously referenced to USDA Forest Service specifications was stated in the standard. The chapter on inspection and tests was reorganized around four subject areas; quality control, inspection, testing, and certification. The 2007 edition• , a general update of the 2002 edition, and clarifies ambiguous recp.:. _- meets. The section for testing elongation, twist, warp, and rise has been revised to clarify the four distinct tests. This edition also requires all new fire hose to be marked with the country of origin so that purchasers are informed where the product is manufactured. 1961-2 FIRE HOSE Technic• al Committee on Fire Hose Stephen Gilbert, Chair Los Angeles, CA [SE] Ray R.

Annex A Explanatory Material Annex A is not a part of the requirements of this NFPA document but is included for informational purposes only. This annex contains explanatory material, numbered to correspond with the applicable text paragraphs. A.1.1 All fire hose has an expected service life. That life will depend on a number of factors, such as the initial quality of the hose, the type of service to which subject_d, and the care it receives during its Life. Users shc:lld dev6op. a fire hose inspection and care-yrogram based on NFPA 1962, Standard for the Inspection; Cave, and Use of Fire Hose, Couplings, and Nozzles and the Service Testing ,of Fire Hose. That program should also address the retirement of fire hose. One of the reasons for keeping good records of fire hose as required by NFPA 1962 is to evaluate how different fire hoses perform over time. This will provide the experience the users need to help them determine what a useful, life is for 1961-13 different types of hose and make decisions on when fire hose should be retired. Limited testing of in-service fire hose by the Fire Equip- ment Manu£acturersAssociation indicated an increased risk of failure after a 10-year time period. The testing looked at the reduction in burst pressure, ozone degradation; liner adhe- --lion-and -degradation, -hose--strength; -normal -wear--patterns, and UV degradation of fibers. While all users should establish their own retirement schedule, fire departments should give careful consideration to a 10-year maximum service life under normal operating conditions. A.f2 This standard is not a decai e manufacturing or pur- chasing specification but can be referenced in purchase speci- fications as minimum requirements. A.1.6 Table A.1.6 provides conversion factors if more preci- sion is required. Table A.1.6 Conversion Factors 1 psi = 6.895 kPa 1 kPa = 0.145 psi 1 psi = 0.0690 bar 1 bar = 14.492 psi 1 in.

Attack hose is designed to convey wa- ter to handline nozzles, distributor nozzles, master stream ap- pliances, portable hydrants, manifolds, standpipe and sprin- kler systems, and pumps used by the fire department. Attack hose is designed for use at operating pressures up to at least 275 psi (19 bar). - A.3.3.4.7 Supply Hose. Supply hose is designed to be used at operating pressures not exceeding 185 psi (12.8 bar). A.3.3.9 Reinforcement. The reinforcement is often referred to as the jacket when it is the exterior layer of the hose con- struction, and hose can have more than one layer of reinforce - men t. The reinforcement is sometimes coated or covered With protective materials. A.4.1.1 A minimum design service test pressure of 300 psi (20.7 bar) for attack hose provides a normal highest operating pressure of 275 psi (19 bar). If a higher operating pressure is needed, a hose having a service test pressure of at least 10 percent greater than the highest operating pressure should be used. A.4.2.2 Whenever supply hose is being used to supply attack lines, master stream appliances, portable hydrants, manifolds, and standpipe and sprinkler systems, a pressure relief device with.a maximum. setting-of-200.ps 13.8_bar)-should.be_used. A.3.2.I Approved. The National Fire Protection Association does not approve, inspect, or certify any installations, proce- dures, equipment, or materials; nor does it approve or evalu- ate testing laboratories. In determining the acceptability of installations, procedures, e ui meat or materials. the author- ity having jurisdiction may base acceptance on compliance with 'NFPA br other appropriate standards. -In the absence of such standards, said authority may require evidence of proper installation, procedure, or use. The authority havingjurisdic- tion may also refer to the listings or labeling practices of an A.4.4.1 This requirement is consistent with USDA Specifica- organization that is concerned with product evaluations and is tion 5100-186D, Forest Service Specification for Fire Hose, Cotton - thus in a position to determine compliance with appropriate Synthetic Lined, WoxsenJacket. 1 inrh• and Ph_ inch, A.4.4.2 This requirement is consistent with USDA Specifica- tion 5100-187D, Forest Service Specification. for Fire Hose, Light- weight Synthetic, Lined, Woven Jacket, 1 inch and P/ inch. A.4.4.3 A minimum design service test pressure of 300 psi (20.7 bar) for forestry hose provides %:monnal highest operating pressure of 275 psi (19 bar). If a '.:.':rer operating pressure is needed, a hose having a service test pressure of at least 10 percent greater than the highest operating pressure should be used. A.5.1 The friction loss characteristics of fire hoses are not included in this standard but are an important consideration in the selection of hose. Friction loss varies considerably de- Pendiit. on the construction and design of the hose, the rou:ir: s of the lining, and its internal diameter, which may be different for different grades of hose. The type of couplings can also affect the friction Toss. Where friction Loss is important, side -by -side :comparisons are recommended. The following test is recommended. All comparative tests should use 300 ft (90 m) of each type of hose to be tested laid side -by -side on a level surface. Commer- cially available line pressure gauges should be installed at the irlet.,r.d the outlet of the first 300 ft (90 m) of hose to be tested. A minimum design service test pressure of 200 psi (13.8 bar) for supply hose provides a normal highest operaung pressure of 185-psi-(4-2:8 bar). If a higher -operating -pressure -is -needed, a hose having a service test pressure of at least 10 percent greater than the highest operating pressure should be used.

A.3.2.2 Authority Having Jurisdiction (AHJ). The phrase "au- thority having jurisdiction," or its acronym AHJ, is used in NFPA documents in a broad manner, since jurisdictions and approval agencies vary, as do their responsibilities. Where pub- lic safety is primary; the authority Laving jurisdiction may be a federal, state, local, or other -._J1iona1 department or indi- vidual such as a fire chief; fire marshal; chief of a fire preven- tion bureau, labor department, or health department; build- ing official; electrical inspector; or others having statutory authority. For insurance purposes, an insurance inspection de- partment, rating bureau, or other insurance company repre- sentative may be the authority having jurisdiction. In many ciccu.iostances, the property owner or his or her designated ag.,o assumes the role of the authority having jurisdiction; at government installations, the commanding. officer or depart- mental official may be the authority havingjiirisdiction. A.3.2.4 Listed. The means for identifying listed equipment may vary for each organization concerned with product evalu- ation; some organizations do not recognize equipment as listed unless it is also labeled. The authority having jurisdic- tion should utilize the system employed by the listing organi- ,.Eatn to identify a listed product. pressureisiieeded,_a hose having.a servicelest_pressure _ofat least 10 percent greater than the highest operating pressure should be used. 2007 Edition 1961-14 FIRE HOSE A-smooth-bore-nozzle--of-At-size-shown- in Table A o.1 should be used for the tests. Pressurize the test hose while the nozzle is fully open until a pitot gauge reading of the dis- charge reads 50 psi (3.5 bar). Read the pressure shown on the inlet and outlet line gauges. Subtract the outlet pressure from the inlet pressure and divide by 3 to determine the friction loss per 100 ft (30 m) of hose. Repeat the test for the next type hose to be tested. The hose with the lowest friction loss will flow the most amount of water for a_given inlet pressure Table A.5.1 Recommended Smooth Bore Nozzle Size for Testing Friction Loss in Fire Hose Recommended Smooth Bore Hose Size Nozzle Size in. mm 1 25 1 r/2 1s/9 2 2r/ 3 38 44 51 65 76 3iF 9 4 4' 5 100 TT3 125- 150 9 2 2%._ 2'/ 13 22 22 22 29 29 the-maximum=warp,-oue-from-the-fitting on -one -end -to -a -point 50 ft (15 m) from that fitting and a second from the fitting on the other end to a point 50 ft (15 m) from that fitting. If the length of the hose is greater than 50 ft (15 m) but less than 100 ft (30 m), some of the hose near its longitudinal center will be included in each segment. A.6.5 CAUTION: Hose meeting the requirements of this standard can be supplied with a coupling that will not be ca- pable of complying with the burst test -requirements of the hose. The purchaser should request information on the fail- ure point of couplings supplied with the hose. A.6.5.3 The burst test is potentially hazardous as the hose can rupture catastrophically. A protecuve enclosure shouldbe used to prevent injury if there is a hose rupture or other failure. Annex B Informational References B.1 Referenced Publications.
