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
Specimen Identification: "FX-100®"
Intumescent Fire Retardant Coating
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.

are included in the Appendix. These sheets are
actual
print-outs of the computerized data system which monitors the ASTM E84
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'.
