"FX-100®
FIRE PROTECTIVE COATING" on plywood panels
The March 24, 1994 test was performed to show the fire
performance
of FX-100®
COATING when applied to standard decking material
(1/2"
CDX PINE PLYWOOD) with a worst case scenario included which involved
the
primary flame impingement being a "joint" in the system. You will
notice
that there were six panels used, each 24 inches in length. This placed
a joint at the point of contact of the test flame in the furnace.
Note that the test did prove similar performance as the U.L.
E-84
performed on Douglas Fir where the flame impingement was not at a
joint.
The intumescent expansion performed well in that it covered over the
small
gap at the joints. The flame spread was almost identical to the
U.L.
test with the only difference being that slightly more smoke was
evolved
from the test sample when the joint was first exposed to the flame as
the
heat affected the ends of the test pieces until sufficient intumescent
expansion insulated the material.

I. INTRODUCTION
This report describes the results of the ASTM E84-91a Standard
Test
Method for SURFACE BURNING CHARACTERISTICS OF BUILDING MATERIALS
(1),
a method for determining the comparative surface burning behavior of
building
materials. The test is applicable to exposed surfaces, such as ceilings
or walls, provided that the material or assembly of materials, by its
own
structural quality or the manner in which it is tested and intended for
use, is capable of supporting itself in position or being supported
during
the test period.
The purpose of the method is to determine the relative burning
behavior
of the material by observing the flame spread along the specimen. Flame
spread and smoke density developed are reported, however, there is not
necessarily a relationship between these two measurements.
"The use of supporting materials on the underside of the test
specimen
may lower the flame spread index from that which might be obtained if
the
specimen could be tested without such support... This method may not be
appropriate for obtaining comparative surface burning behavior of some
cellular plastic materials... Testing of materials that melt, drip, or
delaminate to such a degree that the continuity of the flame front is
destroyed,
results in low flame spread indices that do not relate directly to
indices
obtained by testing materials that remain in place."
This test method is also published under the following
designations:
ANSI 2.5
NFPA 255
UBC 42-1
UL 723
This standard should be used to measure and describe the
properties
of materials, products, or assemblies in response to heat and flame
under
controlled laboratory conditions and should not be used to describe or
appraise the fire hazard or fire risk of materials, products, or
assemblies
under actual fire conditions. However, results of this test may be used
as elements of a fire risk assessment which takes into account all of
the
factors which are pertinent to an assessment of the fire hazard of a
particular
end use.

II. PURPOSE
The ASTM E84-91a (25 foot tunnel) test method is intended
to compare the surface flame spread and smoke developed measurements to
those obtained from tests of mineral fiber cement board and select
grade
red oak flooring. The test specimen surface (18 inches wide and 24 feet
long) is exposed to a flaming fire exposure during the 10 minute test
duration,
while flame spread over its surface and density of the resulting smoke
are measured and recorded. Test results are presented as the computed
comparisons
to the standard calibration materials.
The furnace is considered under calibration when a 10 minute test
of
red oak decking will pass flame out the end of the tunnel in five
minutes,
30 seconds, plus or minus 15 seconds. Mineral fiber cement board forms
the zero point, while the red oak flooring flame spread and smoke
developed
ratings are set as 100.
III. DESCRIPTION OF TEST SPECIMENS

Date Received: 3/23/94
Date Prepared: March 23, 1994
Conditioning (73°F & 50% R.H.): 0 days
Specimen Width (in): 24
Specimen Length (ft): 24
Specimen Thickness: 1/2"
Material weight: N/A oz./sq. yd.
Total Specimen Weight: 117.28 lbs.
Adhesive or coating application rate: N/A
Mounting Method:
The self-supporting sample was placed directly on the tunnel
ledges,
with the coated surface toward the flame.
Specimen Description:
The test sample consisted of six plywood panels, coated by Flame
Seal Products with "FX-100" at a spread rate of 150 sq.ft./ gal.
The panels each measured 24" x 48" x 1/2". The sample was
delivered
to the test laboratory on the test day, per client request.

IV. TEST RESULTS
The test results, computed on the basis of observed flame front
advance and electronic smoke density measurements are presented in the
following table. In recognition of possible variations and
limitations of the test method, the results are computed to the nearest
number divisible by five, as outlined in the test method.
While no longer a part of this standard test method, the Fuel
Contributed
Value has been computed, and may be found on the computer printout
sheet
in the Appendix.

apparatus, and contain all calibration and specimen data needed to
calculate
the test results.
V. OBSERVATIONS
The coating became intumescent at 0:08 (min:sec). Sample
ignition
was observed through the tunnel windows, and occurred at approximately
0:30 (min:sec). Char formed a thickness of 1" at 1:00(min:sec), 1.5" at
1:15(min:sec), 2" at 2:05(min:sec), 3" at 3:25(min:sec), and 4" at
4:15(min:sec).
Maximum flame spread of 2.0' occurred at 9:46(min:sec).
After cooling and removal from the tunnel, the specimen was
observed
as follows: The coating was intumescent to 24', and was approximately
3"
thick. Channels had formed in the intumescent coating at 2', 4', 6',
8',
10', 12', 16' and 20', thus exposing the substrate (plywood) and
allowing
char to form on the plywood. Partial consumption of the plywood
was
noticed between 4'and 5'.
