FIRE
TEST REPORT ON THE FBS®
SYSTEM
INTRODUCTION:
On September 28, 1995, Flame Seal
Products
Inc.
performed a fire test of the FBS® System. This patented
System
is revolutionary in both design and function. It incorporates the
technologies
of intumescence for insulation from the extreme temperatures
experienced
in a hydrocarbon fire as well as endothermic properties for cooling.
This
thin lightweight system with it's "endothermic / intumescent"
properties
is the next generation in passive fire protection products for conduits
and cable trays.
TEST FACILITY:
The test was conducted at the testing facilities of Flame
Seal
Products, Inc. located at 4025 Willowbend # 310, Houston, Texas,
USA.
Prior to the test, the furnace, facility and test methods were reviewed
bv Exxon Corporation and the facility was accepted as an
official
test site.
ATTENDEES:
The Following
companies were in attendance to witness the test
and
verify the results:
ABB
Lummus Crest Inc.
Bechtel Corporation
Exxon Corporation
Fluor-Daniel Corporation
Liondel-Citgo
Peak Seals, Inc.
TEST
STANDARDS:
The
fire test was conducted in accordance with the
time/temperature
curve required by UL 1709. The test was performed on a one
inch
conduit for a period of thirty minutes Circuit integrity was
established
as the pass/fail criteria.
TEST CONFIGURATION:
The one inch conduit was wrapped with the FBS® System
as supplied by Flame Seal Products Inc. The assembly was
placed
in the furnace and a 10 gauge PVC coated cable was pulled through the
conduit.
The cable was connected to a power supply on one end and to a 20" box
fan
on the other. The conduit was filled with ceramic fiber a depth
of
approximately 1" at each end to simulate a continuous conduit run.
Thermocouples attached to individual readers
were used to
monitor
temperatures throughout the testing period. Two thermocouples
were
installed in the furnace(T/C 1 & T/C 2) for the purpose of
monitoring
the temperature rise was in accordance with the requirements of
UL-1709.
The following time/temperature curve was applicable:
1 Minute - 1000 degrees F
2 Minutes - 1200 degrees F
3 Minutes - 1400 degrees F
4 Minutes - 1600 degrees F
5 Minutes - 1800 degrees F
6 Minutes - 1900 degrees F
7 thru
30 Minutes -
2000 degrees F
A tolerance of +/- 10% from the above
time/temperature is allowed
by UL 1709.For engineering purposes, prior to installing
the FBS®
System on the conduit, two thermocouples ( T/C 3
&
T/C 4 ) were installed on the conduit to monitor the temperature rise
on
the cold face side of the System.
TEST RESULTS:
The furnace was ignited at 10:18 AM.
Immediately prior
to
lighting the furnace, the 20" box fan was started for visual evidence
of
circuit integrity. Thermocouple readings were recorded on one
minute
intervals ( see Attachment 1 ). The time/temperature curve
shown above was followed for the thirty minute test period. At
the
end of the test period, the furnace was extinguished. The box fan
was still operational indicating circuit integrity was maintained
throughout
the test. Attachment 2 shows graphically the extreme furnace
temperatures
( T/C's 1 & 2 ) relative to the controlled temperature rise
experienced
on the surface of the conduit ( T/C's 3 & 4 ).
CONCLUSION:
Previous testing on an unprotected one inch
conduit with the
same
type of electrical cable used in this test showed that circuit
integrity
was lost at approximately 500 degrees F. The average temperature
of thermocouples 3 & 4 at the end of the test period was 226.1
degrees
F. The FBS System protected the conduit with a large safety
margin.
Attachment 2 shows clearly how the combination of intumescent
(insulation)
and endothermic (cooling) reaction work together to create plateaus in
the temperature rise during a fire. The thin, lightweight, and
easily
installed FBS® System is the answer to the passive fire
protection
needs of the petrochemical industry.
