Scope
Quality:
The fire hose assembly supplied under this speci-
fication 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
two 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.
a
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 inher-
ent abrasion resistance. The filler yarns shall be constructed
of high strength, low elongation, filament polyester to reduce
weight and increase flexibility.
a
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 Mil-H-24606B for abrasion resistance.
a
Lining
The lining shall be a single-ply extruded tube of synthetic
polyurethane to resist ozone. The polyurethane tube shall
adhere to the jacket to prevent delamination. The finished
product will meet and exceed all potable water Mil-H-24606B
standards for the manufacturing of lightweight fire hose. The
use of the polyurethane lined fire hose is designed to
increase packing ability and applications where lightweight
fire hose is desired.
