INTRODUCTION This report documents the successful fire resistance and hose stream testing of a one-hour load-bearing 10 high X 10 wide, 2 X 4 wood stud wall construction faced on both sides with 5/8 Supress Sound-Engineered Drywall SED58410C performed by Western Fire Center, Inc. (WFCi) for: Supress Products, LLC Howard Stacy and Mike White of WFCi supervised construction of the test wall by WFCi staff, and conducted the test with assistance from technicians Wayne Beres and Nick Martin (WFCi). The purpose of this test was to determine the fire-resistance rating of the wood stud/gwb wall assembly when subjected to ASTM E119 test conditions for a minimum endurance period of one hour. Western Fire Center, Inc. Page 3 of 32
SUMMARY OF TEST METHOD This is a vertical fire test employing the fire endurance conditions described in ASTM E 119-05, Fire Tests of Building Construction and Materials. The test conditions are also closely described by testing standards UBC 7-1, 1997, UL 263, and NFPA 251. A vertical exposure furnace (described in the following section) was used to subject the sample to a standard timetemperature curve as specified in the referenced test procedures. -The neutral pressure plane was located near the top of the wall assembly. -For this fire endurance evaluation, the test was to be performed for a fire resistance period of one hour or until failure of the assembly occurred. Western Fire Center, Inc. Page 4 of 32
DESCRIPTION OF LABORATORY TEST FACILITY The furnace used in the test is a large-scale fire burning apparatus, fueled by natural gas (pictured below). The furnace is mounted to the floor, with the back side close to the west wall, at the south end of the laboratory facility. Inside the laboratory to the north of the furnace is a large area for specimen construction and curing. Ambient temperature in the laboratory is controlled by natural gas radiant heaters at the ceiling level. The wall section is mounted in a vertical orientation into a steel frame specimen holder. The specimen holder is then rolled up to the furnace and secured by four pneumatic rams to the furnace opening. Combustion air and natural gas are supplied to burners through a series of pipes and valves. Internal furnace pressure is controlled by a series of dampers in the exhaust outlets. Temperature measurements are recorded by calibrated data acquisition units which pass the readings to a computer for graphical display and storage. A large roll up door is in the wall opposite the furnace area and allows for the samples to be moved approximately 40 on tracks outdoors to the area designated for hose stream testing.

SAMPLE DESCRIPTION The construction of the 10 tall x 10 wide single leaf fire test wall sample was based upon specifications detailed in UL Design No. U305. The assembly consisted of select structural grade, nominal 2x4-in. Douglas fir wood studs spaced 16-in. O.C. (12 O.C. between first two and last two studs) with two top plates and one bottom plate. All stud and plate pieces were attached with 16d common nails. The external faces of the wall were each covered with one layer of 5/8 Supress Sound-Engineered Drywall SED58410C mounted vertically on both sides (parallel to the supporting elements). The GWB joints on each side were covered with paper tape and gypsum joint compound in the standard manner. The screw heads were also covered with joint compound. Wood Framing: Nominal 2 in. by 4 in. select structural Douglas fir studs bearing the grade stamp of a nationally recognized grading agency, having an average moisture content of approximately 11% percent prior to application of the Supress drywall on the test wall. The average weight of the wood studs was 11.8 lbs, ranging from 10 to 14 lbs. Horizontal blocking was placed across the center of the wall at approximately 60 height. Fasteners: No. 6 x 1-5/8 type W drywall screws spaced at 8 on center on the perimeter and 12 oc in the field; applied a minimum of 3/8 from the vertical edges of the GWB. Supress Sound-Engineered Drywall SED58410C: Single layer 5/8 Supress drywall, having an average unit weight of 2.76 lbs/sq.ft (2763 lbs/msf), and an average caliper of 0.597 in. (as measured by micrometer). As described by the client, the SED58410C drywall product consists of a gypsum and mineral board laminated through a Supress proprietary process. Western Fire Center, Inc. Page 6 of 32
The drywall was attached to the supporting elements with the side with the gypsum wallboard laminate facing out. Both sides of the wall were comprised of three panels of drywall: one 4 x10 sheet, one 44 x10 sheet and one 28 x10 sheet mounted with vertical seams centered over the vertical wood stud structural elements. The mounting of the wallboard was such that the placement of the 28 and 44 wide sheets were on alternate sides of the assembly on the exposed and unexposed sides. Tape and joint compound was applied to fastener heads and joints on the faces of the exposed and unexposed sides in the standard manner.

Weight and Load Information A superimposed axial load of 2,004 pounds per stud (1,804 PLF) was applied to the assembly throughout the test. A graph in Appendix A depicts the load throughout the test in terms of the pounds per square inch (PSI) setting of WFCi s hydraulic load application system. For this calibrated load application, the system was maintained at 358 PSI throughout the test. This loading constituted the maximum fire-rated design stress condition (78% of the maximum design load) for this construction as referenced by the National Design Specifications for Wood Construction (1982 and later editions), and the Gypsum Association Fire Resistance Design Manual, 18 th Ed., Page 7. The load-bearing test was performed by fastening the test wall assembly to the test frame at top and bottom, while leaving the vertical sides unrestrained. The test wall was placed between the top and bottom beams of the load frame with five hydraulic actuators pressing upwards on the moveable bottom beam until the desired load was attained. This axial live load was applied to the test wall approximately 30 minutes prior to the test.

HOSE STREAM RETEST The hose stream retest was conducted on a duplicate wall construction on June 24, 2008 in accordance with the standard. Immediately following the 30 minute fire exposure portion of the hose stream retest, the test assembly was removed from the furnace and moved into position for the hose stream test. The assembly was subjected to the impact, cooling and eroding action of a hose stream applied to the exposed surface of the test assembly. The hose steam test was conducted within 2.5 minutes after the fire exposure was terminated. HS Retest Furn. Temp. Data, 08043 900 800 700 600 Degrees C 500 400 Act. Curve Std.

The hose stream was applied with a 1-1/8 in. diameter nozzle at a Western Fire Center, Inc. Page 17 of 32
perpendicular distance of 20 ft. from the center of the test assembly. The hose stream was applied to the 100 ft² sample and traversed the wall assembly. Hose Stream Retest Results No through projection of water was observed beyond the unexposed surface of the wall assembly after 1 minute. The appearance of the exposed and unexposed surfaces of the wall assembly before and after the fire exposure and hose stream test are shown in Appendix B. TEST RESULTS AND CONCLUSION Charts illustrating data collected from the test are included in Appendix A. Photographs from the test are included in Appendix B. Finish (Membrane Protection) Rating: 0:22:45 The wall assembly supported the applied load for 60 minutes. The wall assembly did not allow passage of flame or gases hot enough to ignite cotton waste at any time during the testing. Temperatures on the unexposed face remained within the allowed single-point temperature rise of 181 C (325 F) above the starting temperature of 15.6 C throughout the test. The average temperature rise for the unexposed face thermocouples remained within the allowable limit of 139 C (250 F) above the starting temperature of 15.6 C throughout the test. A duplicate wall construction successfully met the conditions of acceptance for the hose stream test requirement. The wall assembly met the ASTM E119 conditions of acceptance for a load-bearing 60-minute classification with hose stream, carrying the applied load without passage of flame or heat enough to ignite cotton waste and staying within the temperature rise criteria throughout the test.
