PRODUCT COVERED :
The product covered by this Report is a fire
retardant coating.
USE:
The
coatings covered
in
this Report are intended for use as interior coatings as permitted by
the
authorities having jurisdiction. The established Surface Burning
Characteristics of the coatings are applicable only when the coating
material
is applied in the indicated number of coats, coverage rates,
substrates,
and overcoats and undercoats as specified in the published advises of
Underwriters
Laboratories Inc. and when the coating is maintained.
COATING TYPE:
This Report covers a fire
retardant coating
which
was identified by the manufacturer as "FX-100®".

EXAMINATION OF MATERIAL:
The
material used in
this
investigation was produced in a ready-to-use form under the observation
of a representative of Underwriters Laboratories Inc. and was applied
to
the indicated test surfaces at the manufacturing location.
The
composition of
the coating
material is of a proprietary nature and the formula involved is on file
at the Laboratories for use in the Follow-Up Service Program.
Various
chemical and
physical
tests were conducted on the finished material. The results
developed
from these tests were employed in establishing specifications for use
in
the Follow-Up Service Program.
SURFACE BURNING CHARACTERISTICS TESTS:
SAMPLES
.
Substrate
Douglas
Fir - The test decks were a nominal 22 in. wide and 8
ft.
long, composed of 1 by 4 in. tongue-and-groove Douglas fir flooring
fastened
together on the unexposed surface with wood furring strips. Three
such decks were butted together end to end to form the 24 ft. long test
surface required to fill the Steiner Tunnel furnace.
Coatings
The coating material was
applied to the test
surfaces by a representative of the submitter under the observation of
a staff member of Underwriters Laboratories Inc. The coating
material
was brush applied in one coat. The amount of coating applied was
determined by weight.
One fire retardant coating
was evaluated
under
this investigation and was identified by the manufacturer as "FX-100".
The coating was applied at a rate of 210 sq. ft. per gallon.
The test samples were
conditioned for 28 days
at a temperature of 70 ± 5° and relative humidity of 45 to
55
percent before testing.

METHOD
The tests were conducted in
accordance with
Underwriters
Laboratories Inc.'s Standard "Test for Surface Burning
Characteristics
of Building Materials", UL 723.
.
RESULTS
Data on flame spread and smoke
developed,
results
appear in the following tabulations and as shown on Ills. 1
through 8:
Flame Spread:
The maximum distance the
flame spreads along
the length of the sample from the end of the igniting flame is
determined
by observation.
The Flame Spread
Classification of the
material
is derived by determining the area under the flame spreads distance
(ft.)
versus time (min.) curve, ignoring any flame front recession, and using
one of the calculation methods as described below:
1. If the total
area (At) is less than or equal to
97.5 min. -ft (meter-min. x 3.3), The Flame
Spread
Classification shall be 0.515 times the total area (FSC =
0.515
At).
2. If the total
area (At) is greater than 97.5 min
-ft (meter-min. x 3.3) The Flame Spread
Classification
is to be 4900 divided by 195 minus the total area (At).
(FSC = 4900/(195-At)).

Smoke Developed
The smoke developed during the
test is indicated
by the output of a photoelectric circuit operating across the furnace
flue
pipe. A curve is developed by plotting values of light
absorption
(decreased cell output) against time. The calculated value for
Smoke
Developed Classification is derived by expressing the net area under
the
curve for this material as a percentage of the net area under the curve
for untreated red oak.
