Test specimens were impacted with a 9 lb 2X4 traveling at 50ft per second (Missile Level D). Each specimen is impacted at specific locations to replicate the dangers of wind borne debris in the event of a Tropical Storm or Hurricane.
Test specimens were tested for a design pressure of +/- 70 PSF. In this test, specimens must be tested to 1.5 times the design pressure, that’s +/- 105 PSF, this is typically referred to as the “Structural Test Pressure”.
This test procedure is to replicate hurricane force winds in which a door or window experiences repeated wind loads. The test specimens are subject to 4,500 cycles of wind load in the positive direction and 4,500 cycles of wind load in the negative direction at varying loads.
