results are computed relative to the red oak specimen, which has a rating of <br /> 100, and the inorganic reinforced cement board, which has a 0 rating, and <br /> are expressed as Flame Spread Index and Smoke Density. However, there is <br /> not necessarily a relationship between these two measurements. <br /> PREPARATION AND CONDITIONING OF TEST SPECIMEN: <br /> The panel specimens submitted for testing, selected and identified by the <br /> client, were physically self-supporting and required no further sample <br /> preparation. <br /> The panels were transferred to storage racks in an atmosphere maintained at <br /> 70°F and 50 percent relative humidity and conditioned to equilibrium. <br /> TEST PROCEDURE: <br /> The zero reference and other data critical to furnace operation were <br /> verified by conducting a 10-minute test using 1/4-inch GRC board on the day <br /> of the test. Periodic tests using NOFMA certified select grade red oak <br /> flooring provided data for the 100 reference. The panels were then placed <br /> on the tunnel ledges and tested in accordance with the standard test method <br /> procedure. <br /> TEST RESULTS: <br /> The test results, computed on the basis of observed flame front advance and <br /> the integrated area under the recorded curve of the smoke density apparatus, <br /> are presented in Table II. In recognition of possible variations in results <br /> due to limitations of the test method, the results are computed to the <br /> nearest number divisible by five. <br /> The data for flame spread and smoke developed are shown as solid lines on <br /> the Tektronix 4051 computer print-out at the end of the report. <br /> TABLE I - DESCRIPTION OF MATERIAL TESTED <br /> Material Tested: Faswall Wallform Systems <br /> Manufacturing of Faswall wallforms (WF) and the patented K-X wood <br /> chips is licensed by INSUL HOLZ-BETON INTERNATIONAL, INC., Windsor, <br /> South Carolina. <br /> Date of Test: July 25, 1990 <br /> Composition: <br /> The mix contains K-X treated pinchips from southern pines plus 19.5 <br /> lbs. of Portland cement per cubic foot of treated chips. The fire <br /> side of each panel has been covered with a scratch coat of 1 part <br /> cement and 2 parts sand. <br /> Ar- <br /> 2c4/1 an <br /> n <br /> COMMERCIAL si n <br />
