90 as measured against a particular mode of failure the fm 4450 test requires that the test material resist a minimum uplift pressure of 90 psf without a failure for a duration of one minute the mode of failure tested in the examples set forth herein was the fracture of at least one fastener set forth in table 1 are samples having varying physical characteristics which were tested to determine if the sample possessed the requisite wind uplift resistance the materials are listed in percent by dry weight the fm approvals uplift pressure apparatus is a steel pressure vessel arranged to supply compressed air pressure to the underside of the test panel at pre established schedule the pressure vessel measures 9 feet long u00d7 5 feet wide u00d7 2 inches deep each of the above samples was cut to 4 u2032 u00d7 8 u2032 each sample was mechanically fastened with a diamond in square fastening pattern to a 5 u2032 u00d7 9 u2032 flat steel deck a u201c diamond in square fastening pattern u201d is widely known and accepted by those skilled in the art the results of these tests are set forth in table 2 in the following example the formulation was altered to illustrate the impact such alteration would have on the wind uplift performance in particular the amount of cellulose was deceased to be more in line with conventional fiberboard formulations table 4 pressure comparative time min psf sample 0 01 to 1 00 30 pass 1 01 to 2 00 45 pass 2 01 to 3 00 60 pass 3 01 to 4 00 75 pass 4 01 to 5 00 90 fail 5 01 to 6 00 105 u2014.
