Combat Ready Specifications 1 3/4" and 2 1/2" Factory Mutual Abrasion A sample of coupled hose is H ose Construction submitted to the procedure listed in FM Standard 2111 This hose is designed specifically for aggressive interior or MIL-H-24606B, there shall be no signs of leakage fire attack operations. The outer jacket is woven from staple polyester yarns over an inner liner consisting after 20,000 cycles of abrasion. of a one-piece extruded through-the-weave tube. Cold Resistance Safety Factor Hose shall be capable Combat-Ready is manufactured in a high-visibility white of safe use down to 50 degrees F. The hose shall have with one red and one blue stripe running the length of the no apparent damage to cover reinforcement or lining hose. This heat resistant, drag resistant and kink resistant when subjected to the following cold bending test: A hose shall have superior friction loss characteristics. 50 ft. length of dry hose is coiled and placed in a cold Warranty: Hose shall carry a 10 year written warranty. box at 50 degrees for 24 hours. The hose shall not I show any damage to the reinforcement when subjected nner Hose Properties to hydrostatic acceptance test pressure. When the hose is tested in accordance with NFPA 1961, the liner or cover shall have the following properties: Flashover Resistance Safety Factor Heat resistance is Ultimate Tensile Strength shall not be less than 1500 PSI of the utmost importance when evaluating interior Ultimate Elongation shall not be less than 400% attack hose. This hose shall meet the safety factors for Permanent Set shall not exceed 20% heat resistance without exceeding the normal fire hose Accelerated Aging Test shall meet requirements of UL weight. The hose shall be subjected to a static pressure 19 for accelerated aging of 100 PSI and be capable of withstanding a surface Adhesion between reinforcement and liner shall be a minimum of 20 pounds temperature of 1200 degrees F for a minimum of 45 Ozone Resistance shall show no signs of visible seconds without bursting. cracking of the cover of liner when tested in accordance Water Pick-up Weight The tendency for a hose to with ASTM D1149-91 and ASTM D518-86 (R91), absorb water while in a wet environment can create Procedure B. significant handling difficulties. When tested against Chemical Resistance Exposure to seawater and contamination by most chemicals will have no effect on the procedure listed in MIL-H-24606B, the maximum the short or long term performance of the hose. weight gain shall not exceed 3 lbs. per 50 foot length. Burst Resistance Safety Factor Hose failure due to S afety Factors bursting is the single most important safety concern. Abrasion Resistance bears a direct relationship to the Hose shall have the capability of passing a 500 PSI safe performance of the fire hose. The UL abrasion test service test with a 1/4" diameter hole through both most closely resembles the fire ground use of fire hose and jacket and liner. Only a through-the-weave design liner as such, is considered of prime importance. Hose meeting will be acceptable. Hose shall have a minimum burst all of the abrasion resistance safety factors below shall do pressure of 1500 PSI. so without exceeding average weights. UL Abrasion The hose shall pass a burst test after 5000 Hydrostatic Pressure Tests The hose shall comply cycles on a reciprocating abrasion tester as specified in with the National Fire Protection Association Standard UL Standard 19.
