D8 FIRE HOSE SPECIFICATIONS
These specifications apply to 1 1/2″, 1 3/4″, 2″, 2 1/2″ and 3″ size 800 pound test double jacket 100% mildew proof rubber-lined fire hose. The hose produced under these specifications shall conform to the NFPA 1962 standards during the entire production and assembly process of manufacture. Upon delivery, the hose shall be guaranteed for a period of ten (10) years against defects in material and workmanship. Defective hose will be replaced free
Under these specifications, the manufacture of the hose shall have all necessary test facilities to perform all the required performance tests. The method of testing shall be in accordance with the specific test requirements.
The jacket shall be evenly and firmly woven and free from visible defects, thread knots, lumps and irregularities of twist.
The threads shall be continuous. The warp will consist of high strength staple polyester yarns. The weft or filler polyester yarn will be high strength, low elongation filament polyester.
Impregnation Against Abrasion:
The woven jacket’s abrasion resistance is enhanced by polymer colored impregnation available in red, green, orange, yellow, blue, black and tan. Color will be uniform throughout the length of each hose. Cost for color impregnation is additional.
The rubber liner shall EPDM and a single ply extrusion. The liner shall be free of imperfections. Urethane liners are not acceptable.
The adhesion between the lining and the woven jacket shall be such that the rate of separation of a
1 1/2 inch strip of the lining from the jacket shall not be greater that 1 inch per minute when a weight of 12 pounds is
Under prescribed test procedures, the ultimate elongation, when a break occurs, shall not be less than 500%.
Liner Tensile Strength:
Under prescribed test procedures, the ultimate tensile strength of the rubber liner shall not be less than 1600 PSI.
The internal diameter of the unpressurized hose shall not be less than the trade size of the hose.
When under a hydrostatic pressure of 10 PSI, each hose length shall measure not less than 50 feet when measured from the back of the coupling at one end of the hose length to the back of the coupling at the end of the other hose length.
The hose under hydrostatic pressure testing shall not twist more than 12.5 degrees per foot for the
2 1/2 inch and 3 inch sizes. The amount of twist for the 1 1/2 inch, 1 3/4 inch, and 2 inch sizes shall not exceed 29
degrees per foot. All these must be to the right. No twist to the left is permitted.
Under the hydrostatic test, no rise if allowed.
A straight line shall be drawn from the center of the male coupling to the center of the female coupling at the other end
of the hose assembly. The hose shall not warp more than 10 inches from either side of the straight line.
When under hydrostatic pressure testing, the elongation of the hose shall not exceed 8%.
A three foot sample of hose, whie lying straight or curved around a surface having a radius of 27 inches, shall withstand a hydrostatic test pressure of 1200 PSI without rupturing or breaking any of the thread in the jacket or reinforcement. Hose assemblies, while lying straight or curved around a surface having a radius of 27 inches, shall withstand a hydrostatic pressure of 1200 PSI without leakage, rupturing or breaking of any thread in the jacket or reiforcement, and without
slippage, leakage, or damage of the couplings.
A three foot length of hose lying straight from each lot of 5,000 feet shall withstand a hydrostatic pressure of 1200 PSI without rupturing the hose or breaking of any thread in the jacket or reinforcement.
A three foot length of hose, while kinked, shall withstand a hydrostatic pressure of 800 PSI without leakage, rupturing or breaking of any thread in the jacket or reinforcement.
Coupling Retention Test:
Couplings of lightweight aluminum will be installed. Hose assemblies shall withstand a hydrostatic proof-pressure of 800 PSI for 10 minutes without slippage or leakage of the couplings or damage to the hose at the coupling.
Each length of hose shall be indelibly marked with letters and figures at least one inch high with the following:
a) Manufacturer’s name or coded designation.
b) Trade name or hose designation.
c) Month or quarter and year of manufacture.
d) The words “Service Test to 400 PSI”.
Additional marking may be added based on specific requests.
No hose from stock shall be delivered under these specifications. Hose will be manufactured after the order is received.
