Manufacturer-provided features and specifications as follows
The hose jacket shall be made with high tenacity fi lament
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 per inch (394 per Meter).
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 in 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.
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 1/4” / 6mm per minute under a weight
of 12 lbs / 5.5 kg.
COLD TEMPERATURE FLEXIBILITY
The hose must remain flexible to -65°F (-55°C).
SERVICE, TEST, BURST PRESSURES
Minimum service, test and burst pressures shall be as detailed
in the specification table on the previous page.
A full length will withstand a hydrostatic pressure of
600 psi / 4140 kPa while kinked.
Each length of fi re hose shall not weigh more than indicated
in the specification table.
Couplings shall be in conformance with the current NFPA
standard and made of extruded aluminum, hard coated a
minimum of .002” thick.
They shall be manufactured in North America and permanently
labeled with country of origin. They shall be expansion ring type.
Both hose and couplings must be manufactured in North
America and be NAFTA compliant.
Must be Factory Mutual and UL approved and can be FM and
/ or UL labeled in the sizes specified*
