THE HOSE SHALL BE SINGLE JACKET WITH A SERVICE TEST PRESSURE OF 300 psi/2070 KPA. JACKETS- The jacket shall be made with high tenacity filament polyester yarn in both the warp and weft directions, to provide maximum strength to weight ratio and shall have a minimum filler (weft) yarns of 10.8 per inch (425 per Meter) When requested, the jacket shall be impregnated in one of the standard NFPA colors with high performance dispersion. LINING- The lining (waterway) must be made from polyurethane and must be applied using a fused process that welds the polyurethane directly to the textile while the hose is being woven, without the use of adhesives or hot melt. The fused lining process must create a virtually inseparable unit without the use of adhesives, yielding an extremely low friction (pressure) loss by filling the corrugations of the weave, creating an ultra thin and smooth waterway. Fire hose made using adhesives of any type do not meet this specification. The lining shall be approved for use with potable water. ADHESION- The adhesion shall be such that the rate of separation of a 1 ½”/ 38mm strip of polyurethane, transversely cut, shall not be greater than ¼”/ 6mm per minute under weight of 12 lbs/ 5.5kg. SERVICE, TEST, BURST PRESSURESMinimum service pressure- 300psi/ 2070kPa, minimum test pressure- 600psi/ 4140 kPa, minimum burst pressure 1000psi/ 6900kPa. FLOW AND FRICTION LOSS- The 1 ½” (38mm) hose shall be capable of flowing 70 US GPM (264 LPM) with a maximum pressure loss of 10 PSIG (69 kPa) per 100’ (30.5M). KINK TEST- A full length will withstand a hydrostatic pressure of 600 psi/ 4140 kPa while kinked. WEIGHT- Each length of fire hose shall not weigh more than 11.8 lbs/5.4 Kg uncoupled (30.5M). COUPLING SPECIFICATIONS- Couplings shall be in conformance with the current NFPA standards and made of extruded aluminum, hard coated a minimum of .002” thick. They shall be manufactured in North American and permanently labeled with country of origin. 1 ½” Aluminum forestry couplings NH thread, rocker lug on female only, lugless male. 1 ½” NH thread MANUFACTURE- Both hose and couplings must be manufactured in North America and be NAFTA compliant. STANDARDS- Fire hose manufactured to this specification shall meet or exceed all performance requirements of U.S.D.A spec 5100-187C Type I for 1 ½” (38mm), NFPA 1961, UL & Factory Mutual.
