3 INTRODUCTION This report documents the Urban Wildland Interface testing of ten control and fire resistance-coated samples performed by (WFCi) for: WILDLAND FIRE TASK GROUP (WFTG) Wayne Beres, Logan Byman and Tony Mansur of WFCi conducted the test under the supervision of Mike White (WFCi) on April 5 th and May 6 th, The 4 X 8 samples were constructed at WFCi by John Simontacchi of IFRS prior to testing. A detailed description of the samples can be found on page six of this report. These tests were witnessed by Tom Melum, Yin Wang of Chemco Inc., Ron Loar and John Simontacchi of International Fire Resistant Systems, Steve Quarles of UC Berkeley Forest Products Laboratory, Garrett Tom of Fire Certification Consultants, Bill Hendricks, an independent contractor, and Jim White and Howard Stacy of WFCi. The purpose of these tests was to evaluate the fire endurance characteristics of coated and un-coated samples when subjected to a standard fire exposure condition. This test is used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and is not intended to be used to describe or appraise the fire hazard or fire risk of the materials, products or assemblies.

4 SUMMARY OF THE TEST METHOD Structures at the urban-wildland interface can be very vulnerable to wildfires. They may be threatened by lofted brands (embers), radiation, direct flame impingement, and combinations of these sources. This test method is based on a protocol developed at the University of California, Berkeley, Forest Products Laboratory (UC FPL). The fire test procedure developed at UC FPL addressed three main types of systems used in building construction: 1) decks, 2) walls, eaves and gutters, and 3) roof assemblies. This method is a modification of item 2, and it determines the performance of exterior walls of structures, including siding, soffits/eaves, and gutters when exposed to a simulated urban-wildland interface fire. The UC FPL protocol as written does not have component of thermal radiation exposure for wall systems. The WFTG recommended that a hybrid test method be developed that incorporated the UC FPL Protocol for walls/eaves with the ASTM E1623 ICAL. Figures 1 5 show various views of the test methd utilized in this study. Kelso, Washington Page 4 of 116

8 The exterior wall (siding) test is intended to determine the heat release rate and penetration of fire. The soffit/eaves and gutter tests are intended to determine the performance of these materials under simulated wildfire conditions. All involve direct impingement of flames from a gas burner that simulates the output of dry ornamental plant(s) in close proximity to the structure. Before the test begins, the specimen is vertically mounted to a specimen holder, which permits a prefabricated 4 x 8 ft (1.2 by 2.4 m) wall section to be inserted from the rear and to seal in such a way that protects the edges from fire. The specimen is then exposed to a uniform heat flux from the gasfired radiant panel of the ICAL. The flux exposure should be stipulated by the authority having jurisdiction. Typical values might be in the range of 15 to 35 kw/m 2. This test may be conducted either with or without a pilot ignition applied to the specimen. A 4 x 39 in. (100 x 1000 mm) propane diffusion burner (slot burner) is placed centered against the bottom of the sample and a natural gas output of 40 ±2 kw is ignited if a specimen auto-ignites or at five minutes into the test, whichever occurs first, and is maintained on the sample for another five minutes until the test is terminated at ten minutes, or when failure appears immanent. The time that flaming or glowing combustion continues after the test concludes is noted. During the test, the rear of the assembly shall be monitored for signs of visible flaming or glowing combustion. The test shall be terminated when failure occurs, or when there are no longer signs of flaming or glowing combustion. Temperatures on the unexposed surface shall not exceed 250 F (139 C) above ambient. Kelso, Washington Page 8 of 116

9 During the test, the type of ignition (auto or manual), gas concentrations, heat release rate, mass loss and visible smoke development are determined and measured. The time to ignition and burn through, total heat released and effective heat of combustion can also be determined through observations and calculations. -For this test series, all samples were exposed to 25 kw of flux except for Tests 1 and 7-10, which were exposed to 35 kw.

10 SAMPLE DESCRIPTION All samples were created on-site by John Simontacchi of IFRS, and had 4 X 8 exposed surface area. Some of the samples were then coated with fire resistant paint. The samples were evaluated in a series of 6 tests, as follows: Test 1: 7/16 OSB Control, no coating Test 2: 7/16 OSB Control, no coating Test 3: 3/4 V-Rustic Channel Siding, 10 mil coating of FF88 Test 4: 3/4 Cedar Bevel Siding with Chemco FR Treatment Test 5: 5/8 Cedar V-Rustic Channel Siding Test 6: 1/4 Hardy Plank Test 7: 3/4 V-Rustic Channel Siding, coating of FF88 Test 8: 3/4 V-Rustic Channel Siding, no coating Test 9: 5/8 Cedar Bevel Siding with no coating Test 10: 5/8 Cedar Bevel Siding coated with Armstrong s Wood Stain Oil-Base Formula Three thermocouples were placed 2, 4, and 6 up from the bottom of each sample on the unexposed face. Temperature measurements from these thermocouples appear in graphical form in Appendix A and in tabular form in the Final Data Summary section of this report. The exposed surface temperature was monitored by an optical pyrometer as specified the ICAL standard. Kelso, Washington Page 10 of 116
