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