10D-017 UL Listing Report AND 723 Test January 03, 2007 Mr. Danny French Contego International 334 Greyhound Pass West Carmel, IN 46032 Our Reference: R25382 / 06CA51291 Subject: Report Of Surface Burning Characteristics Tests On Fire Retardant Coating As Submitted By Contego International Dear Mr. French This Report summarizes the results of tests conducted under an investigation identified as Assignment No. 06CA51291. METHOD: Each test was conducted in accordance with Standard ANSI/UL723, ninth edition; dated August 29, 2003, "Test for Surface Burning Characteristics of Building Materials" (ASTM E84). The test determines the Surface Burning Characteristics of the material, specifically the flame spread and smoke developed indices when exposed to fire. The maximum distance the flame travels along the length of the sample from the end of the igniting flame is determined by observation. The Flame Spread Index of the material is derived by plotting the progression of the flame front on a time-distance basis, ignoring any flame front recession, and using the equations described below: A. CFS = 0.515 AT when AT is less than or equal to 97.5 minute-foot. B. CFS = 4900/(195-AT) when AT is greater than 97.5 minute-foot. Where AT = total area under the time distance curve expressed in minute-foot. The Smoke Developed Index (SDI) is determined by rounding the Calculated Smoke Developed (CSD) as described in UL 723. The CSD is determined by the output of photoelectric equipment operating across the furnace flue pipe. A curve is developed by plotting the values of light absorption (decrease in cell output) against time. The CSD is January 03, 2007 Page 2 Contego International 06CA51291.Doc derived by expressing the net area under the curve for the material tested as a percentage of the area under the curve for untreated red oak. The CSD is expressed as: CSD = (Am/Aro) x 100 Where: CSD = Calculated Smoke Developed Am = The area under the curve for the test material. Aro = The area under the curve for untreated red oak. SAMPLES: Sample Description Test No. System 1 blank doug fir. 2 Fire Barrier coated doug fir. 3 Fire Barrier coated doug fir. 4 Fire Barrier coated doug fir. Each test sample consisted of three 8 by 2 ft wide coated douglas fir decks butted end- to-end to form the required 24 ft. long surface. RESULTS: The results are tabulated below are considered applicable only to the specific samples tested. Data sheets and graphical plots of flame travel versus time and smoke developed versus time are also enclosed.
