FIRE ENDURANCE TEST ON PENETRATION SEAL SYSTEMS IN A CONCRETE FLOOR UTILIZING SILICONE ELASTOMERS FOR Brand Industrial Services, Inc.
(BISCO)
Elk Grove Village, Illinois 60007 E1ERPQl{
This report describes the fabrication and test procedures, and lists the results of a fire test conducted on 26 penetration A-seal systems (PSS) distributed in six areas of a 17-ft 9-in. x 13-ft 10 -in. flat plate floor 12-in. thick.
The penetration seal systems consisted of silicone elastomerics, BISCO SF-20 and SF-150L.
These materials surrounded cable trays, conduits and pipes with electrical conductors, or were contained in pipes or conduits with electrical conductors.
A nominal 9-in. thickness
]
of the foam material (SF-20) was used.
A nominal 12-in. thick-ness of the silicone / lead material, BISCO SF-150L was installed.
The systems were installed in rectangular or circular openings in the floor.
Si The test was conducted to evaluate the performance of the discrete penetration seal system and not the performance of the floor assembly.
The specimen was exposed to the Standard fire and hose-stream tests of ASTM Designation:
E119 (1) *.
No passage of flame was noted at any of the 26 penetration seal l
systems at 2 hr test time.
Also, limiting temeprature increases were not reached after 2 hr of exposure at the locations where unexposed surface temperature measurements were made on the foam.
Four areas containing a total of 15 penetration seal
~i systems did not have any flame passage after 3 hr of test.
Unexposed surface temperatures on the foam were measured in two of these four areas (Areas C and D).
Limiting unexposed surface temperatures were not reached after 3 hr of exposure in these two areas.
No water from the hose-stream penetrated the seal system in Areas D, E,
and F.

9 INTRODUCTION The use of silicone elastomerics as sealants for electrical and mechanical items which penetrate fire walls has M
El become common in fossile fueled and nuclear plants.
The first large-scale test to determine the fire resistance of foamed-in-place, medium-density silicone foams, and poured in place, high density silicone / lead matrices (for gamma shielding), occurred in March, 1975, on a wall assembly.
This test, which was performed for Brand Industrial Services, Inc. at the National Gypsum Research Laboratory, in Buffalo, New York, and was reported on by the Factory Research-Corporation, provided information on the behavior of penetration seal systems during a 5-hr fire exposure which followed the ASTM E-119-73 Time-Temperature Curve.
Encouraged by this test, the industry performed additional E-119 type tests during 1975.
The design of the large-scale fire / hose stream test reported here was based on recommendations made by insurance carriers and major architect / engineering firms engaged in the design of nuclear power plants.
As early
[
as November of 1974 the Nuclear Energy Liability Property l
Insurance Association (NEL-PIA) had issued basic guidelines for demonstrating the acceptability of penetration seal systems by means of an E-119 fire test.
In August of 1975, Nuclear Mutual Limited (NML) issued a test procedure for the demonstration of
=1 a
penetration seal system fire endurance, and in December of 1975, NEL-PIA provided a draft of their own test method for 2 --
a r
penetration seal systems.
The NEL-PIA draft was refined and issued in February, 1976 as a NEL-PIA /MAERP Standard Test Method.
Both the NML and the NEL-PIA methods utilized the ASTM E-119-73 Time-Temperature curve,-and are ess'entially in accordance with the Standard.
The test reported herein was A
developed specifically with the NEL-PIA Standard-Test Method in mind.
However, additional penetration seal systems were included to investigate conditions not addressed in the NEL-PIA Standard.
Throughout this report, Penetration Seal System refers
~
not only to the materials that were installed but also to the
))
installation and Quality Assurance procedures which are implemented to provide the high confidence level in the integrity of the finished seal.

Concrete was cured in the form under damp burlap for
]
7 days.
The specimen was then lifted from the casting frame, placed in the floor furnace, and exposed on the bottom surface 9
eg to temperatures of 200-450F for 9 days.
The relative humidity, after drying as determined by Monfore-type hudiidity wells and probe (6), was 55%.at 2-5/8 in. from the bottom surface of the slab and 98% at mid-depth.
Penetration Seal Systems - The test assembly contained six areas each consisting of one or more penetration seal systems (PSS) as shown in Fig. 2 (b).
Twenty-six individual systems were evaluated.
]
Damming materials were installed os the underside of the test assembly.
For conduits and pipes containing single or multiple electrical conductors, loose silica fiber material was tightly packed between the conductors and between the conductors and pipe or conduit.
In some instances where space permitted, an Ethafoam ring was fabricated to fit tightly around the conductors and inside the pipe.
Openings in the y
properly positioned ring were filled with loose silica fiber material.
Cable trays containing electrical conductors, Areas y,
+
A and C, and the 30-in. diameter sleeve containing pipes, Area B, were dammed using Ethafoam sheet material with openings to accommodate the cable trays, electrical conductors, and pipes.
Spaces not dammed by the Ethafoam were sealed with tightly packed loose alumina fiber material.

Description of PCA Furnace ( }
The burner system, hydraulic systems, and other systems of the PCA furnace are uniquely different than other floor
,g furnaces in this country and Canada.
Simply described, the floor furnace is a rectangular shaped, refractory lined steel 4
H box heated by six high-capacity gas burners.
Test specimens wy are nominally 14x18 ft and serve as the top closure of the box.
Two or four restraining elements are employed to support a specimen.
In addition to supporting vertical loads, the
~"
restraining elements transmit the hydraulic force to control A
thermal expansion of the specimen in the horizontal plane as
]
well as rotation due to the dead and live loads and thermal effects.
,n Seven independent hydraulic systems are available for
'F controlling movement of the live load and restraining element ram systems.
The capacity of the restraining systems in the x
ab N1 ---
3 14-ft direction is 1.1 million lb; in the 18-ft direction,
]
1.5 million lb.
The capacity of the live load system is 500 psf.
Six large capacity natural gas burners are mounted on the opposing long walls of the furnace, three per wall.
Each burner has a maximum heat output capacity of about 5 million BTU /hr and project flame across the 12-ft width of the combustion space.
The burners operated in unison lay down a uniform blanket of flame that covers the plan area of the furnace space at the burner level.
Flame turbulence results in further filling the furnace volume with flame to a level just below the tips of the furnace thermocouples.
W.
TEST RECORD Fire Endurance and Hose Stream Tests - The fire and hose-stream tests were conducted in accordance with the provisions of ASTM Designation:
E-119-73 l
Test Soecimen - Penetration seal systems in the flat slab floor assembly was constructed by BISCO personnel.
The assembly was fabricated at the Portland Cement Association Fire Research Laboratory as described under the Fabrication of Test Assembly Section of the Report.
l Fire Test Method - The test assembly was supported on all four edges and tested as a simply supported span.
No service loads were applied.
The underside of the assembly was exposed 1 1
to the Standard Fire ( } in the test furnace for floor II
]
assemblies of the Portland Cement Association.
Furnace atmosphere temperatures were measured with 15 thermocouples that were placed 12 in. below the underside of the concrete slab and iocated a's shown in Fig. 12.
Also shown in Fig. 12 are the variations of the average furnace atmosphere temperature from the Standard Time-Temperature Curve.
The individual furnace atmosphere thermocouple temperatures are shown in Fig. Al and listed in Table Al of Appendix A.
The unexposed surface temperature of the silicone foam materials were measured with 9 thermocouples, each covered with a standard asbestos pad, and located as shown in Fig. 5.
Also shown in the figure are the locations of 27 thermocouples used to obtain temperature information within the foam and on the cables, trays, pipes, and conduits.
Locations of the 5 thermo-couples for measuring the unexposed surface temperature of the l9 concrete floor are shown in Fig.
5.
Complete temperature
.d information is given in Tables A2-A4 and Figs. A2-A43 of Appendix A.
Observations were made throughout the fire test to note the character of the fire, the condition of the exposed and 9
unexposed surfaces, and the performance of the penetration A5 seal systems.
Hose-Stream Test Method - Immediately after the fire tast, the Cloor assembly was removed from the furnace, Fig. 13, 3- _ _ - - ----
1 placed on supports, and exposed to the hose stream, as shown 1.
w in Fig. 14 for 2 min 7 sec.
The exposure time was based on 2
the 117.23 ft area containing the six penetration seal areas 2
less the 32.4 ft area of penetration seal areas A and B.
These two areas had penetration seal systems that flamed through prior to the end of the 3-hr fire test period.
TEST RESULTS Character and Distribution of Fire - The fire was luminous, highly turbulent and well distributed throughout the test.
There were variations in the temperatures recorded by the furnace atmosphere thermocouples, particularly during the first 30 min of test.
However, the average furnace atmosphere vr temperature was well within the 5% variation from the Standard Time-Temperature Curve throughout the 3-hr test period after the first 5 min of the test.

after the hose-stream test.
Figures 19(a), 19 (b), and 19 (c) show the unexposed sides of conduit penetration seal systems (Areas D, E, and F).
Note that the insulation on all of the conductors in these areas is intact.
As viewed from the top, the penetration seal
]
systems of these areas were unchanged from the original condition.
Charred silicone foam material had fallen away from the underside of penetration seal areas prior to and during removal of the specimen from the furnace, Fig. 20.
The 3 l
g-
}
remainder of the charred material and unburned silicone foam material in Areas h, B, and C was dislodged by the hose stream.
Figure 21(a) and 21(b) show the exposed side of Areas B and C after the hGse-stream test.
Insulation on all of the electrical conductors on the underside of the test assembly was burned away during the fire test.
Figures 18(a) and 18 (b) show that some of the cable trays in Areas A and C became warped during the fire test.
The copper wire of many of the conductors that hung down in I
the fire was melted.
The flame impinged on the conductor apparently raising the temperature of the copper above the 1975F melting point.
Other conductors fell away from the cable trays in Areas A and C.
This occurred after the specimen was removed from the furnace and subjected to the hose stream.
Water from the hose stream did not penetrate any of the penetration seal systems of Areas D, E, and F.
Some charred silicone foam material remained in the conduits of the penetration seal systems of these areas.
The charred material was hard as compared to the resilient unburned silicone foam, which in some case was 6-in. thick.
Figure 22 shows the underside of PSS 16 in Area D with the gray charred and black unburned silicone foam materials.

lw Temperatures of the Unexposed Foam Surfaces - Nine thermo-couples were used to measure the temperatures that developed on the unexposed surfaces of the foam materials.
The thermo-4 couple numbers and locations are shown in Fig.
5.
Temperature g
i information from these thermocouples are listed in Table A2 El and shown in Figs. A2-A10 of Appendix A.
I1)
P According to the provisions of ASTM Designation:E119 A
limiting end-point temperatures are reached when the heat
."J transmission through the material is sufficient to raise 1
the average temperature of the unexposed surface of the material 250F above ambient temperature or when the temperatures
- C at any one point raises 325F.
A comparison of the unexposed
- 0 no foam surface temperatures with these end-point limits follows.
Thermocouples 32-36 were used in Area A.
The initial temperature of each thermocouple was 60F.
Therefore, the average limiting temperature was 310F, and the individual limiting temperatures were 385F.
Even though there was a 9
flame-through in this area at 2 hr 11 min test time, the average limiting temperature was not exceeded at 2 hr 30 min.
At this time, the average temperature was 108F.
Individual limiting temperatures of 385F were exceeded at the locations m
of T/C 36, at 2 hr 40 min and T/C's 32 and 33 at ? hr 50 min.
~4 The temperatures at the locations of T/C's 34 and 35 at the m
end of the test at 3 hr were 140F and 260F.
m 4 m 8
l bl 1Wd Unexposed foam surface temperatures were measured in Area C by T/C's 49 and 50.
The limiting average temperature of 320F or limiting individual temperatures of 395F, were f
di not reached at the end of test.
At this terminal test time of 3 hr, the temperatures at the locations of T/C's 49 and g
d 50 were 100F and 110F.
8 Thermocouple 55 measured the unexposed surface tempera-d i
ture in Area B.
Limiting end-point temperatures were not reached at end of test even though flame-through occurred 4c at 2 hr 8 min.
Finally, T/C 56 was used to measure the unexposed surface tsmperature of the 150 pcf density lead foam material in Area D.
At the end of test, the temperature at the location 9
of T/C 56 was 220F, well below the limiting temperature of ao 395F.
Temperatures of the Unexposed Concrete Surface - Five thermo-
- couples, 1-5, were used to measure the temperatures of the unexposed concrete surfaces.
Individual temperatures are m.
given in Table A3 and Figs. All-A15.
,g Temperatures of Conductors, Tray, Pipes and Foam - The
'I temperatures of these components were measured by 27 thermo-couples.
Individual thermocouple temperatures are listed in Table A4 and Figs. A16-A43.

SUMMARY
The test assembly consisted of six areas containing a 4
total of 26 penetration seal systems (PSS).
The assembly
- f J
was subjected to fire exposure for 3 hr followed by a hose-III stream test.
The provisions of ASTM Designation:E119-73 3
were followed in conducting the fire and hose-stream tests.
l I
Pertinent test results are listed.
1.
No passage of flame occurred at any of the penetration seal systems contained in the six test areas of the assembly at 2 hr test time.
2.
Flame-through occurred at PSS 11, Area B, at 2 hr 8 min and PSS 1, Area A, at 2 hr 11 min.
3.
Flame passage did not occur in Area C, containing PSS 12 and 13; Area D, containing PSS 14, 15, and 16; Area E, containing PSS 17 and IS; and Area F, containing PSS 19-26, for the 3-hr duration of the fire test.
]
4.
Liciting end-point temperatures, as defined in ASTM Designation:
E-119-73 III, on the m
unexposed surface of the foam were not 4
reached at 2 hr test time at the nine locations in Areas A, B,
C, and D where surface tempera-
]
ture measurements were made.
].
k h
5.
At the end of the 3-hr fire test period, limiting temperatures on the unexposed-surface of the foam were not reached in
)
Area C, containing PSS 12 and 13; and Area D, containing PSS 14, 15, and 16.
6.
All of the penetration seal systems of f
Areas D, E, and F withstood the hose-stream test.
LABORATORY RESPONSIBILITY The Portland Cement Association was not involved in procurement of materials and fabrication of the penetration seal systems, and makes no judgment of the suitability of materials or seal systems for particular end uses.
The acceptance of the test results for guidance for field
)
installations is the prerogative of the authority having jurisdiction.

Dear Jim:
BISCO'S FIRE PENETRATION SEAL.ING SYSTEM Thank you for your letters of December 5,1978 and January 9,1979 enclosing BISCO's procedures for the installation of fire seals for is" gaps and for the extension of floor or wall seals where the thickness of the floor or wall is less than 9 inches. ' We have reviewed the material and in accordance with our phone conversation of January ll,1979, we have the followiag coru:ents to offer:
1.
BISCO PROCEDURE 1031-1, Rev. 2 " Construction of BISCO Penetration Seals by use of Silicone Caulk"; BISCO Test Report 1042-01, Feb.,
i 1978; and your letter of 12/5/78.
We have 1eviewed the above documents and find the procedure accept-able for use at nuclear power plants we insure. According to our discussions, it would also be acceptable to revise Section 4.4 to read:
" Application of the seals shall include packed ceramic refractory fiber, filled to the full thickness of the penetration opening, but not to exceed 9 inches. This would be followed by applying a layer of silicone caulk to the face of the wall or floor."
If other wording is desired, please advise.
In addition to the above, we would recommend that tests be run on several thickness of the ceramic fiber and silicone caulk, at some time in the future. Although considered acceptable for now, I
from an engineering standpoint, it would be worthwhile to " prove" your minimum thickness. We would also recommend that future tests use hose stream configurations that are listed in our Standard
' Test Method. On page 8 of the Test Report, the distance should have been 5 ft. for a 300 discharge angle (or,10 ft. for 150).

Your letter of January 9,1979 and attached Drawing 1064-11-1.
As we discussed, this concept is considered acceptable for use at nuclear power plants we insure. Although we prefer to see the system installed as shown, due to apparent structure stability, it would be acceptable to reverse the design and have the extensions on the underside of the floor.

During our phone conversation, a unique problem was brought-up concerning the depasition of a " future hole" in a 3" Q deck floor.
It would be acceptable to fill this opening with 3" of ceramic board, tightly fitted, with a diamond plate steel cover. We are aware of the fact that a similar design, but with only 2" of ceramic board, domonstrated an acceptable temperature rise in a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> test.
Jim. I believe that this summarizes our last phone conversation.
If you have any questions or comments, please do not hesitate to call.

Dear !!r. Zmed:
METROPOLITAN EDISON COMPANY THREE MILE ISLAllD - UNIT NO. 1 ANI FILE NO. N-155 We have received and reviewed your fir. Hoover's submittal of July.24,'1978 regarding the installation of "flane barriers" in the penetration fire stops balc,w tha itin Control Console.
The "M" Board strips will be seated in the silicone foam fire stop'and extend above the foam material to prevent the spread of flame along the' surface.
These fire breaks becane necessary since the original dividers within the' fire t
stop, were covered over with silicone foam during the installation.. :The details shown and described are Acceptable to American Nuclear Insurers for Insurance Purposes Only.
Our final acceptance will be based upon a random inspection by'.ouf Field Engineer.
Since ely, h 4 Jl R. G. Sawyer RGS/jms Senior Administrative. Engineer cc: Mr. John Mezaraups, Project Engineer - Metropolitan Edison' Company Mr. J. R. McVey, Vice President - Frank B. Hall & Company Mr. William Brannen - Gilbert Associates

ISCO Mr. Nick Miller BISCO 630 Bonnie Lanc Elk Grove, IL 60007 Nick:
For situations where four-part silicone foam (blend of 3-6531 foam and Sylgari 170) must be patched, such as repenetrations, DON CORNINGe 3,-6548 silicone RTV foam should work well.
3-6548 foam is compatible with the four-part silicone foam formulation and should provide a good seal,.when applied to a clean and dry surface.
In regards to your second question, different lot numbers of parts A and B of 3-6548 foam can usually be combined.
The criteria here is the resulting snap time.
If the snap time is between 1 and 3 minutes, the resulting foam will be within che specifications for 3-6548 foam.
