Hydro Flow Small Diameter
Nitrile Rubber Light Weight Attack Hose

Detailed Specifications


1.  Hose Construction

1.1 Hose meeting this specification shall consist of 100% synthetic high tensile yarn reinforcements circular plain woven so as to eliminate any left hand twist.

1.2 The woven reinforcement of the inner hose shall be totally encased in a matrix of ozone   resistant  nitrile rubber utilizing a single, THROUGH THE WEAVE EXTRUSION PROCESS, thereby eliminating the possibility of delamination.

The unitized finished product shall thereby optimize hydrostatic properties, abrasion resistance, and rubber to yarn adhesion.

2.  Lining and Cover Properties

When tested in accordance with the procedures listed in NFPA 1962-02 and other related standards, liner and cover shall have the following properties.

2.1 Ultimate Tensile Strength: Tensile strength of inner lining and cover rubber compound shall not be less than 1750 psi.

2.2 Ultimate Elongation: Ultimate elongation of inner hose liner and cover shall not be less than 500%

2.3 Permanent Elongation: Permanent elongation of liner shall not be greater than 25%

2.4 Accelerated Aging Test: When using conditions as listed in ASTM  D1349-87, samples of the vulcanized rubber compound subjected to air oven aging at 100 degrees C for 70+/- ½ hour and then tested in accordance with ASTM D573-88 will exhibit a tensile strength of not less than 80% of the unaged sample.  The ultimate elongation shall be not less than 50% of the original value.

2.5 Adhesion: Adhesion between liner reinforcement and liner shall be a minimum of 22-½ lbs. When tested using NFPA 1961-02 procedure.

2.6 Ozone Resistance: Hose liner shall show no visible signs of cracking of liner or cover when tested in accordance with ASTM D1149-91 and ASTM D518-86, Procedure B 100 pphm/118 degrees F/70 hours.

2.7 Chalking: Hose finished to this specification shall not react adversely to environmental changes (chalking caused by exposure to sunlight).

2.8 Chemical Resistance: Exposure to seawater and contamination by most chemicals substances, hydrocarbons, oils, alkalis, acids and grease must have no effect on the short or long term performance of hose. 
Manufacturer shall provide standard Chemical resistance charts.

3.  Safety Factors

3.1  Abrasion Resistance Safety Factors: Abrasion resistance bears a direct relationship to the safe performance of the hose on the fire ground and as such will not be compromised.  The Reciprocating Test – listed first – is felt to most closely reproduce the fire departments actual fire ground conditions and is therefore considered of prime importance to the purchasing authority.  Hose meeting all the abrasion resistance safety factors listed below shall do so without exceeding the average weights listed in paragraph 5.3 of this specification.

3.1a   Safety Factor to Damage – U.L. Reciprocating Test. Safety factor to damage hose outer jacket shall withstand 7,000 cycles on a reciprocating abrasion tester – as specified in U.L. Std. 219 – resulting in no delaminating or damage to the reinforcing yarns. Hose so abraded shall comply with section 4.1 of this specification.

3.1b Safety factor to Exposure – Tabor Test. Hose shall withstand 16,000 cycles on the Tabor abrasion machine cH22 wheels, 1000-gram total load per wheel without any exposure of the synthetic reinforcement fibers.  Test to be preformed in accordance with ASTM D3389-85. Wheels must be re-faced       prior to commencement of test.

3.1c   Safety factor to Damage – Tabor Test.  Hose shall withstand 24,000 cycles on the Tabor abrasion machine H22 wheel, 1000 gram total load per wheel without damage to the synthetic reinforcement fibers.  Test to be preformed in accordance with ASTM D3389-85.  Wheels must be re-faced prior to commencement of test.

3.2    Cold Resistance Factor:  Cold resistance bears a direct relationship to the safe performance of the hose on the fire ground and as such will not be compromised. Hose meeting the cold resistance listed below shall do so without exceeding the average weights listed in paragraph 5.3

3.2a Hose shall have a capability of safe use down to –36 degrees F. Hose shall have no apparent damage to cover, or liner when subjected to the following cold bending test:  A 50-foot length of dry hose as to be firmly coiled and placed in a cold box at -36 degrees F. for a duration of 24 hours.  Immediately after removal of hose from box, hose should be uncoiled and laid out by one operator.  Following this procedure the hose shall not leak or show any damage to the reinforcement when subjected to hydrostatic acceptance test pressure as listed in item 4.1

3.3    Heat Resistance Safety Factor: Heat resistance bears a direct relationship to the safe Performance of the hose on the fire ground and as such will not be compromised.  Hose meeting the heat resistance safety factors listed below shall do so without exceeding the average weights listed in paragraph 5.3 of this specification.

3.3a The hose when subjected to a static pressure of 100 psi shall be capable of safely withstanding a surface temperature of 1200 degrees F. for a minimum of 2 minutes without bursting.  Heat resistance to be demonstrated on request of the purchasing
authority.
