Test Report eTR-109 Page 1 of 27 A) Synopsis: This report describes a three hour fire and subsequent hpse ~ ~ ~ stream floor test of Transco #TCO-001/U.S. Gypsum Firecode CT Gypsum Cement used in a large electrical opening. The fire test was performed in accordance with the ASTM E-119 time / tem-perature curve for three hours and provisions for testing penetration seals set forth in the IEEE 634-78, ANI, NML, and ASTM E-814 (for a "F" rating) test standards. This penetration seal was tested along with 26 other openings in a large 17'-9" x 13'-10-1/2" concrete slab on March 9, 1983, at Portland Cement Association's Fire Research Laboratory (Skokie, Illinois). The opening measured 109-1/2" x 32" x 12" deep and had two sub-strate surfaces which consisted of 1/4" thick steel plate while the remaining two substrate surfaces were cast concrete. Three cable trays and two conduits penetrated the opening. Two of the trays (one ladder and one solid back) and one conduit were filled with PVC jacketed cable. The third tray and other conduit were filled with Hypalon jacketed cable. The two trays with PVC jacketed material were located 1/16"-1/8" from the substtates at each end of the penetration in order to show the sealing material's ability to seal narrow spaces. The third tray was located 17-3/8" from one end of the penetration.

Test Report #TR-109 Page 2 of 27 The opening was filled with 5" of Transco #TCO-001/U.S. Cypsum Firecode CT Gypsum Cement. Fou,r inches of #TCO-009/U.S._ Gypsum Thermafiber damning material was used to dam inside of the cable trays and conduits (only). No damming material was used for the areas outside of the trays and conduits. Transco #TCO-001 cement is a water based, 20-35 lbs./cu.f t. material. It is normally mixed with an accelerator to produce a rigid material which can be easily altered. The materials, used for this test were mixed with varying amounts of water and accelerator (and in some batches no accelerator was used) in order to demonstrate the material's installtion versatility. During installation, the material's consistency ranged from a stiff material which had to be troweled in place to a soupy liquid which flowed and self-leveled. It should be noted that a small hairline crack developed at the center of the seal's surface (this crack was not visible from beneath the slab). The single surface crack was the result of a slight amount of linear shrinkage of the material (this is a normally occurring characteristic of this material). It should also be noted that the seal had been walked upon on several occasions prior to the actual fire test. Although no damage was visible, standing on ~ the seal is not recommended since it is a very thin, unsup-ported material. f

Test Report #TR-109 Page 3 of 27 Besides qualifying the seal to the test standards mentioned, severalotherobjectiveswereestablishedinthistest.f[ These are: I 1. The materials ability to seal both narrow and wide areas without support; 2. The material's ability to provide the desired fire protective qualities even if surf ace cracks occur and when the material is-installed using a variety of water and accelerator to dry material ratios; 3. The use of material to seal both solid and ladder back cable trays; 4. The use of the material when installed next to either steel or concrete substrates; 5. The use of a damming board divider (used in several sections) to separata larger field openings into sections which are equal to or smaller than the penetration tested; ,6. The ability of the sealing material to be removed for additional cable installation; and, 7. That a symmetrical 5" thick seal can withstand the 3 hour fire and 2 hose separate stream tests. B.) Test Slab: The test slab measured 17'-9" x 13'-10-1/2" x 12" thick. Twenty-seven openings which ranged from 1-1/2" diameter to 7 109-1/2" x 32" in size penetrated the test slab. The penetra-

Test Report fTP.-109 Page 4 of 27 tions were arranged in the slab so that 18" wide (min.h concrete columns separated eac'h row of penetrations. khese columns were placed in the direction which would allow for the least amount of deflection from heat during 'the fire test. The slab's steel reinforcement design and actual slab fabrication wert completed by Portland Cement Association's personnel. After the slab was cast, the concrete was allowed to cure for several days af ter which the slab was subjected to additional heat curing on a furnace. The slab's superstructure and specimen fabrication and seal installation was performed by Transco employees. The slab's ~ superstructure consisted of steel angle braces mounted to the slab which supported the pipes, cable trays, cables, etc., for the test. C.) Specimen Configuration: The test penetration measured 109-1/2" x 32" x 12" deep. Two sides of the penetration were lined with 1/4" thick steel plate (set at a right angle in the plan view of the penetration). The remaining two substrate surfaces were cast concrete. a e The opening was penetrated by three cable trays and two conduits. Each cable tray was mounted so that it extended 36" above the slab's unexposed surface and 12" below its exposed ~

T2ct Rsport #TR-109 P gs 5 of 27 ) surface. The conduit sleeves were 12" long and mounted flush inside of the penetration. The cable trays and conduits were filled with cable based on loadings which exceeded 1 0% fills. The loadings were calcu-lated so that a 100% fill was equivalent to 40% of the actual sectional areas of the cable trays or conduits. Some of the loadings were increased so that 100% visual loadings were also chieved. Cable loadings were as follows: 1 1.) 24" x 6" solid back cable tray filled with Hypalon i i jacketed cable: 7 4 pr. #20..................... 0.4185...... 2.9295 5 1 pr.

(117.4% fill of conduit) All cables used in the test extended 36" above the slab's unexposed surface and 12" below its exposed surface. Cables were held to the trays with both compression clamps and cetal plates located approximately 12" from the top of each tray. In addition, a threaded rod was used across the bottom of each tray to prevent the cables from being pulled forward during the seal installation. This was done to simulate field conditions where continuous cables make it impossible in some cases to move the cables apart for seal installation. The conduits were welded directly to the steel substrate. This was performed to show the sealing material's ability to fill a space which gets increasingly smaller (following the curvature of the conduit to where it is welded to the substrate). The cables used in these conduits were held to a bar which was located approximately 30" above the slab. The top ends of all cables used inside of cable trays were covered ~ with silicone adhesive while conduit cable ends were taped. This was completed in accordance with IEEE-634-78 requirements.

Tast Rtp3rt #TR-109 Page 8 of 27 D.) Seal Installation: The opening around the cable trays and conduits was firbt formed with plywood and supported from the floor below (any other smooth, removable form can be used in field installations or an approved noncombustible material can be used if damming is to remain as a permanent part of the installation). Four inches of #TCO-009 damming material was then installed between the cables to hold the liquid #TCO-001 cement material in place until set (and remained in place as part of the permanent seal between the cables only). The #TCO-001 cement was then installed 5" deep cve c the forming materials. The cement material was mixed both in a dispensing machine and by hand in plastic buckets to demonstrate both conditions. Varying amounts of water were used in both cases to produce a material consistency which ranged from a flowable, soupy liquid to a thick material which had to be placed by trowel. Varying amounts of liquid and dry accelerator were also used from batch to batch (and in some cases, no accelerator was used). This wide rar.ge of installation techniques was used to demonstrate the ~ material's fire protective properties when batches as described are installed and when set percentages of water and accelerator to dry ~ material might be altered by the installer to suit field conditions. m T-

Tzst Rtport #TR-109 Page 9 of 27 Af ter the cement had been placed, its surface was trowelled smooth. An additional light coating of #TCO-001 cement (approximately 1/4" thick) was sprayed onto all PVC jacketed cable to a hefght of 12" above the already installed 5" thick seal. The Hypalon1 jacketed cables were not sprayed with any additional material. Af ter the materials had hardened, a wooden rod was used to bore a small hole through the cement in front of the cable tray holding the Hypalon jacketed cables while a second hole was made in front of the ladder back tray filled with PVC jacketed cable. One 12/C #14 Hypalon cable was then added to the Hypalon cable tray and three 12/C #14 PVC cables were added to the ladder back tray through the holes. The spaces around the cables were then filled with additional cement and da= ming material to simulate field conditions where a finished seal might be altered for the addition of cables. It should be noted that prior to the installation for the cement material, a section of 1" thick Johns-Manville Ceraboard (81b. density) was set perpendicularly in front of the solid back cable tray filled with PVC jacketed cable. This section of board material consisted of three separate sections of the board which were butted up against each other across the width of the penetration. The section of board was as high as the cement seal surrounding it. This board was installed to demonstrate field conditions where pene- ~ trations larger than the penetration qualified in this test can be divided using the board material into sections the same size or smaller to meet the size limitations of this test. l l

Test Report #TR-109 Page 10 of 27 E.) Thermocouples: Thermocouples were mounted to the test specimen to gather te=perature data throughout the test at five minute in{e}rvals for 1 the first two hours and at ten minute intervals for the remaining f hour (in accordance with IEEE 634-78). Temperatures were recorded for the seal surface (in eight different locations), concrete and steel substrate / seal interfaces, at tray / seal and conduit / seal interfaces, on seal surfaces of conduits, and at cable / seal interfaces. In each cable tray and conduit, thermocoupes were mounted to typical instrument, control, and power type cables. Where the cables were covered with a sprayed coating (in the cable trays and conduit which were filled with PVC jacketed cable), the ,thermo couples were attached directly to the cables at the surrounding seal surface (beneath the coating). All seal surface thermocouples were embedded approximately 1/4-1/2" deep into the seal's surf ace. Where thermocouples were used to measure cable, substrate, tray, or conduit temperatures, the thermocouples were also embedded 1/4-1/2" deep into the interface surfaces. The thermocouples used in'this test along with final temperature readings at the conclusion of the test are as follows (temperature data for the entire test can be found in Section H of this report): o l r

Furnace: I -lhe furnace used for this test measures approximately.14' x 18' at its support points. It is approximately 7' tall making it possible - to work on the specimen's exposed surface and view it prior to the fire test. The furnace atmosphere is controlled by six self-igniting burners which f burn natural gas and operate in unison. The burners are automatically controlled by a computer located inside of the control, room. As the furnace atmosphere temperatures are monitored in the control room, manual adjustments can be made to account for varying amounts of fuel contri-bution throughout the test.

Test Report #TR-109 Page 13 of 27 The furnace atmosphere temperatures are monitored by 15[thermocouples . located II" below the test slab. These temperatures are individually printed on a continuous chart and also averaged on a computer print-out. The furnace draf t is manually operated and averaged approximately .08" of water pressure throughout the test. Since manual adjustments are made to the burners in order to follow the ASTM E-119 time / temperature curve, brief periods of positive pressure are introduced inside of the This is evidenced by visible puffs of smoke generated through furnace. any openings in the test specimen (i.e.,' through a fire damper, unsealed ' pipe insulation, etc.). ~ G.) Test Record: The fire test was conducted for three hours in accordance with the ASTM E-119 time / temperature curve. Throughout the test, an even blanket of flame covered the plan area of the furnace. All combustible materials located on the exposed surf ace of the slab quickly ignited and continued to char throughout the test. During the first 2 hours of the test, very little smoke was generated from the cables used in this specimen. Water began to evaporate through the hairline crack (noted prior to the test) at the center of the seal. This was evidenced by moisture highlighting the crack. ~ i l

Test Report #TR-109 Page 14 of 27 During the test, the west side of the penetration's subitrate (concrete [ with the 1/4" thick steel plate liner) was level. This portion of the 1 ~~ slab was supported by the edge of the furnace and remained level. Although no deflection of the slab was noted here, slab expansion did occur as evidenced by 1/16"-1/8" wide cracks at the corners of the slab. The opposite side of the penetration (cast concrete with no steel liner) was not supported by the edge of the furnace and as a result was exposed to more heat than the concrete substrate with the steel liner. This lack of support and exposure to greater heat caused the concrete to expand and visibly deflect downward into the furnace. The downward deflection of the concrete resulted in a combined shear / twisting action on penetration seal during the fire test. The most severe downward deflection of the concrete occurred near the damming board divider. During the fire test it was observed that the seal twisted and sloped here to follow the slab's deflection. At this point of the severest slab deflection, several small cracks and a small bulge occurred on the seal surface. This was a result of strain release of the twisted seal. During the fire test, higher surface temperatuers were obtained in this area. After the fire test, it was noted that some of the seal's exposed surface had fallen from this area also. Outside of i the area of the seal affected by the deflection of the slab, seal surf ace temperatures remained relatively cool and no loss of material was observed after the conclusion of the test. l

Test Report #TR-109 i Page 15 of 27 Within the last hour of the test, the PVC jacketed cables began to swell 1 near the seal surf ace causing cracking in their coatings. This swelling was not observed on the Hypalon jacketed cables. A light density smoke generated from the PVC cables for the duration of the test. Two hose stream tests were conducted on the concrete slab and pene-t tration seal. Water did not penetrate any portion of the seal during either test. The first hose stream test consisted of spraying the exposed surface of the 17'-9" x 13'-10-1/2" slab with water delivered from a 1-1/2" hose equipped with a fog nozzle set at a discharge angle of 15* at 75 p.s.i. from 10' for 6 minutes and 18 seconds. The second hose stream test was identical to the first except that the nozzle was set at a discharge angle of 30*. i H.) Temperature Data: The following sheets identify both furnace atmosphere and unexposed surface temperatures obtained through the fire test. e d . l

Test Report #TR-109 ) Page 23 of 27 I.) Post Test Observations: Af ter the hose stream tests were concluded, the exposed surface of the seal was available for viewing. It was noted that most of the sealing material was intact. Several cracks appeared across the ' bottom of the f seal which were caused by the intense heat of the fire test. Pbterial had fallen jgom the seal's exposed surf ace near the damming board divider. Approximately 2 to 2-1/2" of material had fallen from the seal which was af,fected by the greatest amount of surrounding slab deflection. It was in this area where higher seal surface temperatures were experienced during the fire test. The seal's unexposed surface remained completely intact throughout the fire and hose stream tests. The only visible change noted was the swelling on the PVC materials and several small cracks in the area of the slab deflection. As the seal was removed for slab destruction it was observed that the PVC jacketed cables completely charred through the seal. The Hypalon jacketed cables charred approximately 1-2" into the seal's exposed ~ surface. = ,~-

Dear Mr. Hoff:

We have reviewed the Transco Fire and Hose Stream Test Reports of Penetration Seal Systems A through H submitted with your letter of June 26, 1981 to Bill Bornhoeft. These tests of cable and pipe penetration fire stops were conducted at Construction Technology Laboratories of the Portland Cement Association on flovember 17, 1980, and March 10 and 11, 1981. Enclosed are two copies each of the ANI/MAERP Fire Stop System Acceptance form for the configurations that successfully passed the fire endurance and hose stream tests. ANI cannot extend acceptance to your repair procedure for FIRECODE CT Gypsum Cement at this ' time due to the burn through at Cable Tray-- No. 3 where the two power cables were added to simulate a repair. If we can be of any further assistance, please do not hesitate to contact us. Sincerely,

• Y' Ah t=\\

? Immediately after the fire test, the specimen was removed l from the furnace and exposed to two hose-stream tests. These - l , hose-stream tests met provisions of American Nuclear Insurers (ANI) Method No. 2 (2) and IEEE 634-Method No. 1..( 3) l Flaming on the unexposed surface was noted at 1 hr 26 min ' f ter start of test in the area of Tray No. 3. The flame was a extinguished by covering with ceramic fiber blanket material. The test continued until a 3-hr exposure time was reached. Limiting ' temperature increases were not reached on the unexposed surfaces of the concrete or the FIRECODE CT Gypsum Cement., No water from either hose-stream test penetrated the seal systems. SPECIMEN DESCRIPTION Following is a description of the materials used in the ^ construction of the concrete floor slab and penetration seal systems. ' Reinforcina Steel All steel reinforcing bars and stirrups used in the concrete I43 slab were ASTM Designat' ion: A615 Grade 60 steel with a minimum yield' strength of 60,000 psi. Concrete Concrete was made with sand and gravel from Algonquin, i Illinois. The aggregate is predominantly dolomitic. Ready mixed concrete was used. One test was made for slump, unit weight, and air content from approximately each cubic yard t T

of concrete. Batch quantities, properties of plastic concrete, and strength information are listed in Table 1. TABLE 1 - MIX DESIGN AND CONCRETE PROPERTIES ~ i ktem Quantity Type I Portland Cement, lb/cu yd 517 Water, lb/cu yd 258a Sand, lb/cu yd 1,340 Gravel, 1-in. Max.

FIRECODE CT Gypsum Cement FIRECODE CT Gypsum Cement, is a specially formulated light-weight, frangible gypsum cement which expands upon setting. Flow characteristics have been designed to permit complete i filling of voids between cables without excessive lateral. flow' - - -- when properly mixed and installed. FIRECODE CT Gypsum Cement requires only the addition of water to mix'and can be applied either by machine or hand. j FIRECODE CT Accelerator, dissolved in water, can be used 'f with FIRECODE CT Gypsum Cement to quicken set time. I r-gw,* e e rn,-,,,-- n-

Damming Materials ~ The following materials were used to contain the. fluid I gypsum cement during the time required to form a solid mass. All damming materials were removed after the FIRECODE CT Gypsum Cement hardened. THERMAFIBER CT Felt' 7HERMAFIBER CT Felt is a 4-lb/ft nominal density, high-melt point compressible mineral fiber felt easily cut and shaped with a serrated knife. It is used as a form for retaining poured FIRECODE CT Gypsum Cement in floor and wall firestop openings. Carborundum Fiberfrax Hot Board Fiberfrax Hot Board is a refractory bonded rigid insulation processed and dried on special insulating block equipment. It is manuf actured to be flat and true on all surfaces and has a uniform composition and density throughout. Cable Trays All trays used were US Gypsum Company Galvanized steel trays, 5-f t long, 18-in. wide, and 4-in. deep. Four solid i bottom and four ladder back trays were used in the test specimen. Electrical Conductors All copper wire electrical conductors used to fill trays and the conduit were non-rated IEEE-383 (5) cables. Cable types are listed below: (a) 600V, 2/C #16 AWG, polyethylene insulation, PVC jacket each conductor, PVC jacket overall. -g-

~. L-(b) '600V, 7/C fl2 AWG, polyethylene insulation, PVC jacket each conductor, PVC jacket overall. (c) 600V, 1/C, 300 MCM, PVC overall. Conduits The 6-in. diameter pipe used in the test assembly was a nominal 6-in. diameter, schedule 40 pipe with 6.625-in. O.D. and 0.280-in. wall thickness. Angle Bars Structural angle bars 3x3-1/i6 in, secured to the, slab were used to anchor cable trays and electrical conductors in the conduit penetration system. FABRICATION AND CONDITIONING OF TEST ASSEMBLY Following are details concerning the fabrication and con-ditioning of the concrete test slab and penetration seal systems. Concrete Slab The 14-f t long x 9-f t wide x 12-in. thick concrete floor slab was designed to simulate a simply supported span of a con-crete structure exposed to fire on the underside for a minimum period of three hours. Design of the flat slab generally fol-lowed the strength requirements of ACI Standard 318-77(6) The slab contained two areas consisting of a pipe embedded in the concrete, and an opening to accommodate the penetration systems. The penetration systems were positioned in the slab l i ( as shown in Fig.1, -W

All st' eel reinforcing bars were ASTM Designation: A615 Number.7 Grade 60 steel with a minimum yield of 60,000 psi. and 8 bars were 'used for major reinforcement. Stirrups were in. on center in f abricated from No. 3 bars and were placed 12 the long direction. Concrete was distributed into the form with an overhead The top ~ dumpbucket and consolidated.with internal vibrators. surface was leveled with a screed and finished with a magnesium ~ ~ float. I Concrete was cured in the form under damp burlap for 7 days. The specimen was then lif ted from the casting frame, placed in the floor furnace, and exposed on the bottom surf ace to tem-peratures of 200-450F for 7 days. 4 Penetration Seal Systems each contain-The test assembly was divided into two areas, ing one seal system. The large opening (Area A) Fig. 1 con-tained a seal system consisting of eight cable trays surrounded The other with a 5-in. depth of FIRECODE CT Gypsum Cement. system, (Area B) Fig. 1, was a steel pipe conduit containing electrical conductors surrounded by a 5-in. depth of FIRECODE f CT Gypsum Cement. Damming materials were used initially to f acilitate the installation of the FIRECODE CT Gypsum Cement until set but were then entirely removed. Carborundum Fiberf rax " Hot Board" (supplied in 2x4 f t x 1 in, sheets) was used to dam all areas of the opening except those areas in and around electrical Cable areas were dammed using shredded U.S. Gypsum cable.

o .z ~ THERMAFIBER CT Felt (supplied in 2x4 ft x 4 in. batts). THERMAFIBER CT Felt was the only damming material used in the - 6-in. opening. ' Damming and FIRECODE CT Gypsum Cement installation activ-itieswerepefformedbyTranscoandU.S.Gypsumpersonnel ~ following Transco Quality Assurance Procedores FSQAP 8.0 and r 9.0, respectively. Other applicable Transco QA procedures were also utilized to perform this work. A Quickspray Carrousel Pump was used to' install the FIRECODE. CT Gypsum Cement. Hand mixing and applications were also utilized in some cases. All FIRECODE CT Gypsum Cement applica-tions were accomplished following applicable Transco QA pro-cedures and in accordance with U.S. Gypsum Technical Bulletin TAC-216/USG/10-80. Following is a description of each of the penetr3. tion seal systems and the installation details for each. area. Area A - This area was 5-f t wide x 6-f t long and contained one penetration seal system consisting of eight cable trays loaded, with electrical conductors. The installed FIRECODE CT Gypsum Cement was air dried on both sides using electric fans for approximately four (4) weeks prior to the fire test. The four ladder-back trays were located in line on one half of.the opening. The four solid back trays were positioned in line on the other half of the opening. Trays and cables were surrounded by a 5-in. depth of FIRECODE CT Gypsum Cement. Con-auctors were secured to ladder-back trays with plastic ties and to solid-back trays with U-shaped, 1/4-in. threaded rods. Trays a e

s ~ in this area were supported by steel angles fastened to the slab with 1/4-in. bolts threaded into self-drilling tubular expansion shield snap-off anchors embedded into the concrete. Each cable tray was filled 40% full with the, electrical conductors as stipula'ted by ANI. The 40% fill requirement, based on cross-sectional area of tray, was divided so that each of the three types of non-rated IEEE cables occupied 33-1/3% of the filled tray. The finished trays wer then anchored to the concrete slab with angle steel. The 5-f t long trays extended the .1-ft below the bottom surface of the slab and 3-ft above top surface. Area B - The 6-in. conduit opening was filled approximately 35% three types of full,. based on cross sectional area, with the non-rated IEEE electrical conductors. Cables were surrounded with a 5-in. depth of FIRECODE CT Gypsum Cement. Cables in the ~ conduit extended 1 f t below the bottom surf ace and 3 f t abov'e the top surface of the slab. Conductors were held in place by securing them to steel angles that were f astened to the concrete slab. Details of the penetration systems are shown in Figs. 2 through 9. In order to evaluate a repair procedure, two 1/C power cables were removed from Tray -No. 5 and installed in a hole made in the FIRECODE CT Gypsum Cement of Tray No. 3, as shown in Fig. 10. These power cables were not coated with FIRECODE CT Gypsum Cement,above the unexposed surface of the penetration i

TEST RESULTS Observations during the test and test results are given in the following paragraphs: ~ Character and Distribution of Fire The fire was luminous, highly turbulent and well-distributed th roughou t the test., There were variations in the temperatures recorded by the furnace atmosphere thermocouples, particularly during the first 20 min. of test. Ilowever, the average furnace a tmot p.here temperature was well within the 5% variation from the S tandard time-temperature curve thoughout the 3-hr test period. observations During Fire Test TEST TIME REMARKS HR: MIN ~ 0:00-0:05 Insulation on cables in the furnace began to smoke \\ and burn. Furnace filled with smoke and flame from burning cable insulation. Near zero visi ~ bility made the observation of the exposed surface a of the test assembly impossible for most of the test'. "i i 0:26-0:35 Smoke was noted in all areas of the ladder-back cable trays. i 6

? g,, TEST TIME REMARKS ~ HR: MIN Smoke was noted in all areas of the solid back 0:35-0:55 cable trays. 1:26 Flaming occurred at and above the interface of the FIRECODE CT Gypsum Cement and th'e jacket of a 1/C 300 MCM cable within the area of Tray No. 3. 1 The cable that ignited was one of two cables that were agged to the penetration af ter the initial FIRECODE CT Gypsum Cement installation. Flames were smothered by covering with ceramic fiber blanket material. 2:15 Smoke cleared in the furnace allowing the obser-vation of the underside of the specimen. All of the insulation was burned from the cables in the trays in the furnace. The FIRECODE CT Gypsum Cement w'as not cracked and appeared intact throughout the penetration areas. 3:00 The furnace was turned off and the fire test terminated. At this time, no flame was observed on the unexposed surf ace. e

.s - Additi6nal Observations Af ter Fire Test TEST TIME REMARKS HR: MIN Specimenwasli[tedoutofthefurnace. The 3:08 underside of the specimen was smoking a'nd flaming, as shown in Fig. 13. Smoke was coming from the top side of the specimen. The specimen was placed in a vertical position for the hose-stream tests. 3:12 Bottom surf ace of test assembly was exposed to tv ANI Hose-Stream Test No. 2. No water penetrated the unexposed surface for the 2-min 30-sec exposure. 3:20 Test assembly was exposed to the IEEE 634-78 Rose-S tream Test No. 1 for 2 min 30 sec. No water penetrated through the unexposed surf ace of the test assembly. Steam and heavy black smoke filled the area around the test specimen and upper levels of the fire laboratory. Close observations of this specimen was not possible at this time. Additional water from the fire hose at low pres-sure was applied to the surf aces of the specimen to prevent reignition on the exposed side of the specimen and to inhibit smoke generation. 3:35 Smoke cleared in the Laboratory enough to allow observation of the test assembly.

~ Observations After the Hose-Stream Test Insulation on all of the electrical conductors on the m underside of the test assembly was burned away during the fire l test. All cable jackets on the unexposed side of the specimen ' melted, or partially melted, at least to a distance of 1-ft above the top surface of the slab, as shown in Fig. 14. No flaming of cable jackets on the unexposed side of the slab occurred during the test except at the retrofit area. No open ings occurred in the /IRECODE CT Gypsum Cement seal d,uring the fire and hose-stream tests. The exposed surface of the specimen after fire and hose-tests is shown in Fig. 15. Unexposed Surface Temperatures Thermocouples were used to measure temperatures that deve- ~ loped on the unexposed surface of the FIRECODE CT Gypsum Cement. ~ Three thermocouples were used for temperature measurements on the unexposed surface of the concrete. Thermocouple numbers and locations are given in Fig. 11. Temperature information for these thermocouples is listed in Appendix A. According to the provisions of ASTM Designatio.n:

E119, limiting end-point temperatures are reached when the heat-transmission is sufficient to raise the average temperature.of the unexposed surface of the material 250F above ambient temperature or when the temperature at any one point rises 325F.

The provisions of IEEE 634-78 give the limiting unexposed temperature rise at 325F above temperature at start of test.

With initial temperature of 77F, the. limiting temperaturo average would be 327F and the limiting temperature at any one ' ; ' po' int on the unexposed surface would be 402F. These limiting temperatures were not reached on the unexposed surfaces of the ~' ~ FIRECODE CT Gypsum Cement and concrete' slab during the 3-hr ~ fire exposure. Average temperatures were 203F and 133F for the FIRECODE CT Gypsum Cement and concrete surfaces, respectively. Maximum temperature on the FIRECODE CT Gypsum Cement unexposed surf ace was 385F, and 147F on the concrete surface. tv Temperatures of Electrical Conductor Cables, Jackets, and Cable Trays In the solid bottom cable trays, cable jacket temperatures ranged.from 880F to 1229F. Cable j acket temperatures ranged from 1088F to 1248F in the ladder-back cable trays. The highest cable jacket temperature recorded within the 6-in. conduit was 606F. Flaming of cable jackets occurred only at the retrofit area on the unexposed side of the slab. The highest temperature recorded was 505F on a solid bottom tray and 405F on a ladder back tray. Individual temperatures for cable jackets and cable trays are listed in Appendix A. SIRGIARY The test assembly consisted of two areas containing two penetration seal systems. The assembly was subjected to fire exposure for three hours followed by two hose-stream tests. I i i - m r

Applicable provisions of ASTM Designation:

E119, IEEE-634-78, and ANI Fire Test Guidelines were followed in on-ducting the fire and hose-stream tests.

The following are test results: (a) At 1 hr 26 min, a 1/C 300MCM cable in Tray No. 3 ignited on the unexposed side of' the test assembly. This cable was one of two cables that were added to the penetration after the initial FIRECODE CT Gypsum Cement installation The cable ignited by ~ autoignition?" The light coating of FIRECODE,CT Gypsum Cement on the cable jackets above the slab, was not applied to the two cables added in the repair procedure. (b) The flame was smothered using ceramic fiber b}anket ,No other flaming occurred on the unexposed material. surf ace for the remainder of test.- (c) The maximum cable jacket temperature in the' trays was ~ 1248F. (d) The maximum cable jacket temperature in the 6-in. con-duit seal system was 606F. (e) Maximum cable tray temperatures were 505F for solid bottom' trays, and 405F for ladder back trays. (f) Limiting unexposed surface temperatures of the FIRECODE CT Gypsum Cement and concrete slab, as given in ASTM Designation: E119 and IEEE 634-78, were not exceeded. The highest temperature recorded on the FIRECODE CT Gypsum Cement surface was 385F, and 147F G 'on the concrete surface. Average temperatures were _(( __ 203F for the FIRECODE CT Gypsum Cement and 133F for - the concrete slab surface. (g) The seal systems passed hose-stream tests ANI Method No. 2 and IEEE-634 Method No. 1. (h) An inspection of the FIRECODE CT Gypsum Ceme'nt seal after the fire and hose-stream tests did not reveal any cracking or damage t'o the seal material. 7 LABORATORY RESPONSIBILITY The Construction Technology Laboratories, a Diviskon of the Portland Cement Association, was not involved in fabrication of the penetration seal systems and makes no judgment of the suit-ability of materials or seal systems for particular end uses. .The a:ceptance of the test results for guidance for field installations is the prerogative of the authority having jurisdiction. e e i i i l t h

Transco CT Gypsum Fire Test Report (Portland Cement Association)

Dear Ed:

l As requested, please find enclosed a Transco fire test report for a fire test conducted at Portland Cement Association (Skokie, Illinois) on U. S. Cypsum's l Firecode CT Gypsum Cement. A copy of this test report was requested by the NRC during the meeting at LaSalle held on December 14, 1982. I've also enclosed a summary of the test which I wrote shortly af ter the test. j A few points about this test which you might want to explain to the NRC when sub- ~ i mitting this test report: 1. This test was not conducted to satisfy any requirements fer LaSalle. This test i was conducted by Transco for applications at all plants, with our primary purpose j being to obtain ANI Acceptance of this test. 2. Unexposed side flaming did occur during this test. However, this flaming occurred at one cable only due to auto-ignition, not due to a flame through. This particular cable was added through the completed CT Gypsum seal to demon-strate a cable retrofit. 3. All cables used for this test were totally PVC jacketed (non-rated) and trays were loaded to 40%. All cables used at LaSalle are, of course, rated to i IEEE-383. 4. No,' damming materials remained in place during the test. ; The CT Gypsum was poured to a nominal fill depth of 5". 5. The CT Gypsum unexposed side surfaces never exceeded the temperature limitations as stipulated in ASTM E119/IEEE-634. 6. The CT Gypsum seals never allowed through passage of fire or smoke to the 4 unexposed side of the slab and passed two-(2) hose stream tests, not allowing any water penetration to the unexpos,ed side of the slab. .n --.,4 3 , +. -,, - - ,--<,,v.,_ w- - - ~ r-y<,,w" r*'*+--e***

pCA Fire Test - Sunnary Please find' attached a sketch of the slab layout and a page describing itars shown on the sketch, and the testing standards used for this test. 'Ihe test uns held on Abnday night, Novenber 17, 1980. Eis fire test uns conducted for three (3) hours at temperatures averaging 18000F. Dere were a total of 48 thennocouples placed on the unexposed side of the floor slab in various , locations - 12 on the 2 Gnductor Control Cables, 7 on the 7 Conductor Contml Cables, and 8 on the 1 Conductor 300 103 power Obles. All of these thennocouples were placed ct the interface of the gypsum material and the cable jackets and the distribution was 3 thenrocouples on 3 cables per cable tray plus 3 thenrocouples on 3 cables within the conduit; 1 thenroccuple was placed on each cable tray at the interface of the gmsum nnterial and the cable trays, for a total of 8 thenroccuples; 10 thenroccuples were placed directly on the gypsum surface,1 in fmnt of each tray and 2 in the mid-section; the last 3 thenrocouples were placed on the concrete slab at randan locations. 0 In the solid bottan cable trays, the highest cable tanperaturcs mcorded wem 1229 F (2C), 888 F (7C) and 11820F (IC). In the ladder back cable trays, the highest cabic temper-atures recorded were 10SSOF (2C),1248 F (7C), and 11810F (1C). %e highest tanperature 0 recorded within the 6" conduit uns 60G0F (IC). De highest tcmperatum mcorded on a solid bottan cable tray uns 5050F and on the ladder back cable tray, 4050F, D e highest tenperature recorded on the gypsun surface uns 3850F and on the concrete surface,1470F. 0 The averag^ temperatures recorded were 8500F (2C cable), 776 F (7C cable), 965 F (IC cable), 0 0 369 F (solid tray), 360 F (ladder tray), 203 F (gypsum surface) and 133 F (concrete 0 surface). A ter:perature of 700 F (maximun allcrxable cable tanperature per IEEE-634) or greater was first recorded on cables at the following tines - 75 minutes (2C cable), 80 minutes (7C cable), 75 minutes (IC cable). A tcmperature of 4020F (rrnximum allownble gypsuu tan;crature per ANI @ 770F ambient) or greater was not reached on the gypsun surface during this test. Smoke uns noted in all the solid back cable trays between 26 minutes and 35 minutes. Stroke sus noted in all the ladder back cable trays between 35 minutes and 55 minutes. At 86 minutes, flaming occurred (and uns quickly extinguished) on a IC 300101 cable within a solid back cable tray. 'Ihis was the only flaming which occurred on the unexposed side of the slab during the entire test. %e test was cenninated at 180 minutes and two (2) successive hose stream tests wem conducted. ne first hose stream test was conducted per ANI Method No. 2 which requires a 1-1/2" nozzle,15 degree discharge angle, nozzle pressure of 75 psi, nozzle discharge of 75 gpn and a distance of 10' for a period of 2-1/2 minutes. He second hose stream test uns condoded perIEEE-6M which is identical to ANI Method No. 2 except the discharge angle is 30 degrees instead of 15 degrees. Both bose stream tests were. successful with no water what-so-ever penetrating the gypsum seal in either the tray opening or the conduit opening. OBSERVATIONS: 1. '4be cable which ignited (IC 300 103 cable) was one (1) of two (2) cables which were added to the penetration after the initial gypsun installation. % cse two cables were added to demonstrate gypsun's alterability. 2. During the initial gypstrn installation, all cables on the unexposed side were lightly coated with gypsum to a distance of. I' above the slab. We cable which ignited was not coated with gypsum above the slab. 3. All cable trays contained cables which exceeded 1000 F except one (1) ladder tray which had a maximum cable tcmperatum of 6390F (2C cable).

7* ~. 3 4. All cable jackets on the unexposed side melted or partially nelted at least l' above the slab. 5. As dononstrated by the two (2) successful hose stream tests, no openings occurred in the gypsun seal during the fire test or during the hose stream test. 6. he cable which ignited did so because of auto-ignition, not because of a burn through. Auto-ignition occurs when the heat generated on the fire side is trans-mitted through the cable to the unexposed side of the slab and the temperature of the cable jacket on the unexposed side of the slab is high enough to ignite the cable 0 jacket (His tonperature is 700 F per IEEFeG34). 7. Although all cable trays except one (1) contained cables which greatly exceeded the 7000F ignition limit, no other cable ignited except the one (1) described in item #1. I believe the reason no other flaming occurred was because of the light gypsum coating on all cab 1cs (except the cable which ignited) to a distance of l' above the floor slab. 8. In future testing one (1) of two (2) changes or a combination of both should be made to the gypsun seal we install; 1) increase the fill depth of the gypsun;

2) leave daming materials in place.

I would also reconnend applying a light coating of gypsun to the cable jackets above the slab as uns done during this test and this light coating should also be applied to any cables added after the initial installation. 9. he gyp seal used during this test (5" gypsu) was based on successful smaller scale testing conducted by U.S. Gypsum Company. Dere were several reasons for raroving all damning nnterials after the gypsun installation; 1) U.S. Gypsum had successfully tested 5" of gypsun with no damning materials; 2) if damning materials are used and zumoln in place on one (1) side during the floor test, we would be required to use damning materials on two (2) sides when the same seal is used in wull penetrations, which would increase labor costs; 3) if damning materials are used and remain in place during the test, we would be required to use only those specific damning unterials used during the test, whereas if no damning materal is is used, we would be allowed to use any non-ccmbustible damning materials to make the seal installeon/ 4) where ampacity is of great concem, damning materials used to nnke the gypsum installation could be reroved to reduce the ampacity derating factor.

Dear Mr. Watts:

After completing our work of identifying all electrical openings in Unit 2 that require fire seals, we have concluded there are no vertical cable riser penetrations in Unit 2 or Unit 1 that exceed 40% of riser volume. following: This justification is based on the Control or Instrumentation Riser: % Riser Fill = $Y 4 x Design Index 4 x 100 Power Riser: % Riser Fill = "D' ~l-x Design Index 6 x 100 for instrumentation and control risers and 3.05 for power Upon review of the most current cable pan loading summary report of CIS-3, for both Unita 1 and 2, there are no risers at La Salle County that have design indexes that would exceed the 40% cable fill density.

Dear Mr. Seckinger:

Per the requestdbf Mr. R. L. Bartlett, TAC Divi-sion-Technical Representative, attached is a copy of a presentation made to Sargent & Lundy and Transco Inc. personnel on February 11, 1982 on FIRECODE CT Gypsum Cement. The presentation dealt with the crystalline and calcination characteristics of the product. ,If you have any further questions, please feel ~ free to contact either Mr. Bartlett or myself. Sincerely yours, Robert G. Lange Research Manager Industrial Plasters /ps cc:

f Calcination (CaSO 2H O) Gypsum: Calcium Sulfate Dihydrate 4 2 characteristics as they pertain to FIRECODE CT Gypsum Cement i Gypsum and its primary dehydration product, calcium sulfate hemi-H O), have been used for years in fire retardant hydrate (CaSO - 4 2 construction. Gypsum is a naturally occurring mineral which is processed to form the hemihydrate present in FIRECODE CT Gypsum Cement. The gypsum is calcined or heat treated to remove 75% of its combined water to form hemihydrate. The calcination begins at approxi-mately 120*F (49'C). However, in normal production the calci-nation process is carried out at 250*F (12]'C). After calcination is completed, the hemihydrate is further processed and then foppulated with various additives to pro-i duce FIRECODE CT Gypsum Cement. In use, the FIRECODE CT Gypsum Cement is mixed with water. The hemihydrate and water Seact to form an interlocking, crystalline structure of gypsum crystals. The crystal structure formed is what maintains the integrity of the FIRECODE CT Gypsum Cement when it is installed as a penetration seal of fire break. FIREC' ODE CT Gypsum Cement is protected through the use of special additives to resist calcination up to 150*F (66'C). Above this temperature, calcination will occur at a slow rate.

However, the crystalline structure formed during the rehydration reaction is left intact and only under high magnification examination using a scanning electron microscope can any difference in the crystal structure be detected.

The changes which occur during this calcination are: a slight weight loss due to the removal of combined water, a reduction in strength, which does not affect the penetration seals' fire protection performance, and a decrease in thermal conductivity (k-value) from 1.00 to 0.65. The fire protection capabilities of a calcined sample are equal to those of uncalcined samples for the applications using FIRECODE CT Gypsum Cement. /Ps 9
