Scope

Quality: The fire hose assembly supplied under this specification shall be constructed with superior quality materials. NFPA 1961 standards shall be observed in production of the assembly, in order to ensure its quality and durability.
Service Life:Hose furnished under these specifications will have a potential service life warranty of not less than ten years; barring mistreatment that would render it unfit for service. Upon delivery, the hose shall be free from defects in workmanship and materials.Any defective hose will be replaced at no charge whatsoever.

Jacket Construction

The jackets will be woven evenly and be free of defects, including knots, lumps, or unsightly disfigurations that could jeopardize the integrity of the hose assembly. The warp yarn shall consist of staple polyester yarn. The use of filament or entangled yarn is expressly forbidden due to the lack of inherent abrasion resistance. The filter yarns shall be constructed of high strength, low elongation, filament polyester to reduce weight and increase flexibility.

Abrasion Impregnation

Hose assemblies are available with polymer impregnation that provide additional abrasion resistance. Colors include: yellow, orange, red, tan, black, blue and green. Color shall be pure and even in each hose. Impregnated hose shall meet the requirements of Mill-H-24606B for abrasion resistance.

Lining

The rubber lining shall be a single-ply extruded tube of synthetic EPDM compounded to resist ozone. The finish form shall be free of pits or other imperfections and have a smooth finish. No reclaimed rubber shall be used. Plastic tubes that sacrifice durability of the hose life for the sake of weight are not acceptable.

Backing: The backing shall be of adequate thickness to create a smooth waterway but not greater than .020. The fire hose constructed under this specification shall be manufactured fully backed using a calendered EPDM. The use of adhesives of any kind are acceptable and expressly forbidden.

Tensile Strength & Ultimate Elongation: Shall meet the standards of Underwriters Laboratories, Inc.TM as well as all other properties of UL-19 for rubber lined hoses. A valid U.S. Underwriters inspection procedure shall be in force.
