PROJECT 4835-02-1 DECEMBER 14, 1976 o

f.6STRACT A. concrete test assembly containing a cable tray with cables, four electrical conduits (two with cables), and a pipe and pipe sleeve assembly was subjected to a one hour fire exposure afterwhich the assembly was subjected to a water stream frcm a fire hose / nozzle, as described in ASTM Standard E 119, Section 8. The cable tray and area surrounding it, and two conduits containing electrical cables were sealed with BISCO SF-20 Silicone Foam. Two empty conduits were scaled with BISCO SF-150L High Density Silicone, and the pipe and sleeve assembly was sealed with a BISCO Flexible Boot seal. fio water was observed to have penetrated the seals during application of the hose stream.

TEST OBJECTIVE The objective of the testing was to demonstrate the ability of BISCO Penetration Seal Systems to withstand the hose strpam phase of the ASTM E 119 Standard Fire Test Method. Successful performance of the hose stream phase when applied to the data obtained in a large scale E 119 fire test conducted by Factory Mutual Research Corpt ation in March 1975 provide the basis for certifying that the SISCO Penetration

' Seal Systems will perform as three hcur fire barriers, as specified in Bechtel Company Specification 7749-M-255.

CONSTRUCTION OF TEST ASSEMSLY Testing was performed on a concrete slab fitted with penetrating items, as described in BISCO Procedure 4835-02. Attached drawing 4835-02-1 details the configuration of the test assembly. ,

A 6" by 24" solid bottom cable tray equipped with ladder type rungs approximately 18" on center was loaded with EPR Neoprene jacketed  !

cables to approximately 465 of the tray area. The cables viere tied .

into the tray and the assembly was anchored to the test slab. J i

PENETRATIO;l SEALS PROJECT 4835-02-1 DECEMBER 14, 1976 Two 3" diameter conduits were grouted into the concrete assembly, and were filled with BISCO SF-150L High Density Silicone cs describ-ed below.

A 3" diameter conduit containing EPR fieoprene jacketed cables (approx-imately 45% loaded) and a 4" diameter conduit containing EPR Hypalon jacketed cables )approximately 215 loaded) were grouted into the con-crete assembly and were filled with BISCO SF-20 Silicone Foam. The cabic tray and area surrounding the tray was also sealed with SF-20 Silicone Foam as described below. -

A 6" ID pipe sleeve was grouted into the concrete assembly. A 3" ID pipe was centered inside the 6" sleeve and the sleeve / pipe construction was sealed with a BISCO Flexible Boot Penetration Seal. The Boot Seal included Inconel wire mesh and ceramic fiber fill which were placed around the 3" pipe within the concrete slab to effect a fire barrier.

IftSTALLATIO!! 0F pet 1ETPATIO!! SEALS Damming materiais to contain the liquid SF-20 and SF-15CL components were placed flush with the bottom surface of the test assembly to provide a seal the full 12" thickness of the concrete slab. Major areas around the cable tray were dammed with Ethafcam. Voids between the cables in the tray were dammed with BISCO CFR-2300 ceramic fibers.

Ceramic fibers were also used to dan around cables in the two conduits and to provide the fire barrier within the sleeve / pipe construction.

Damming was performed in accordance with BISCO Procedure OMI-1.

BISCO SF-20 Silicone Foam was foamed-in-place in the two conduits con-taining cables and around the cable tray using automatic dispensing equipment. BISCO SF-150L High Density Silicone was poured-in-place into the remaining two conduits by hand. The formulation and blending cf the SF-20 was as described in BISCO Procedure 207-M, and the form-ulation and blending of the SF-150L was as described in BISCO Procedure 209-M.

I Installation of the penetration seals was performed in accordance with BISCO Procedures 207-IP, 209-IP, and 204-IP.

The SF-20 and SF-150L seals were allowed to cure for approximately 88 hours0.00102 days <br />0.0244 hours <br />1.455026e-4 weeks <br />3.3484e-5 months <br /> prior to fire testing.

HOSE STREAM TESTING PROJECT 4835-02-1 DECEMBER 14, 1976 TEST METHOD and FACILITIES The concrete test assembly fitted with penetrating items and sealed as previously described was subjected to a controlled temperature fire. The portland Cament Association small scale floor furnace was used to provide the necessary ties temperature exposure defined by ASTM E 119. This furnace subjects a 48" by 43" assembly to a fire exposure unif:rmely distributed to a central area of the assembly 30" by 30", where all of the seals were located.

Standard Test Method ASTM E 119 describes the time-temperature relation-ship required for the fire exposure. The relationship is commonly know as the " time-temperature curve". The furnace is equipped with thermocouples which measure the furnace atmosphere temperature and transmit tnis information to a multipoint chart recorder, which dis-plays individual temperatures vs. time, and to an integrating recorder

  • which averages the temperature measurements and prints the average vs.

time on a circular chart. prior to the start of the test the time-temperature curve is hand drawn on the chart papers for ready visual reference. Figures 1 and 2 are reproductions of thase furnace atmos-phere temperature records.

Because the hose stream phase of the E 119 test does not require it, no information is presented which indicates the unexposed surface temperatures encountered during the test. This data was, however, accumulated.

As directed by the Standard, the test assembly is' removed frem the furnace after a one hour fire exposure, and subjected tc a stream of water from a fire hose equipped with a National Standard Playpipe having a 1-1/8" standard-taper, smooth-bore, sholderless orfice discharge tip.

The d.istance from the nozzle orfice to the center of the test assembly is to be 20'. f Table I o' fASTM E 119 provides the' requirements for water pressure and duration of application of the stream, which is dependent on the desired rating of the tested assembly. To obtain a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> rating, as required by the Specification, a p. essure of 30 psi and a duration of 150 seconds per 100 square feet of assembly is required. The overall size of the test assembly was four feet by four fe'et, or 16 square feet. A 24 second hose stream application at 30 psi was called for.

As defined by the E 119 Standard (copyright- ASTM) "The assembly shall be considered to have failed the hose stream test if an opening developes that permits a projection of water frca the stream beyond the unexposed surface during the time of the rose stream test".

.' DECEMBER 14,'197E PROGRESS of TEST ,

Testing was performed on December 14, 1975 at Portland Cement Assoc. , -

Skokie, IL. -

- The concrete assembly was subjected to a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> - 3 minute fire ex-posure consistant with the time-temperature curve defined in ASTM Standard E 119. , ,

Almost irrediately after the start of the fire test smoke was observed

~

coming from the area close to the cable tray. It is believed that the smoke was the result of the Neoprene jacketing on the cables celting within the silicone foam seal. Since the furnace operates at a negative pressure, smoke below the seal would be drawn dcwnward and exhauste J.

The presence of smoke above the test specimen indicates that a seai was present around the cables, and also that the temperature of the cables above the bottem of the seal was sufficient to cause the insulation to decompose. .

During the last half hour of the fire test water was ' observed arcund several of the grouted-in conduits. Grouting of this specific test

, asserably was performed in July 1976, and the water was due to the de-hydration of the grouted portions.

After I hr. 3 min. the test assembly was removed frcm it vertical position on the furnace and moved by crane to a mobile platform. The test assem-bly was moved to a horizcntal positica and transported tc an area adja-cent to the research laboratory to receive the Fese stream. The total time taken in removing the slab frcm the furnace and positioning it was 3 min. 4 sec. -

With the test assembly 20' from the discharge tip of the fire hose, and normal to the stream of water, the application of the water stream began.

The stream was directed first at the middle of the assembly and then at all parts of the specimen.

Observations were made during the hose stream application froa behind and slightly to the left of the assembly, as viewed frca the front. For

, added insurance the water strean was continued for a total duration of slightly over 30 seconds. No water was seen to penetrate the assembly.

Observations of the unexposed face of the assembly after test revealed that no openings had developed in any of the penetration seals.
