Each section was reinforced <br /> with two (2) 3" deep x 20 gauge galvanized steel struts. The door sections were connected together with one <br /> (1) 14 gauge galvanized steel end hinge at each end stile and one (1) 14 gauge galvanized steel center hinge <br /> at each of the three center stiles as shown on the drawing. Garage door Model No. 1500D manufactured by <br /> Amarr Garage Doors was used in the test. <br /> The test unit is further described on drawing SBC -580 -019. <br /> Witnessed by: Tony East - Amarr Garage Doors <br /> Danny Joyner - Amarr Garage Doors <br /> Thomas L. Shelmerdine, PE - STRUCTURAL SOLUTIONS, P.A. <br /> Manner of Testing: <br /> The specimen was tested for static pressure structural performance in substantial conformance with the <br /> procedures described in ASTM E330 -90 "Standard Test Method for Structural Performance of Exterior <br /> Windows, Curtain Walls, and Doors by Uniform Static Air Pressure Difference". Both positive and negative <br /> pressures were tested. <br /> The specimen was installed in an enclosure measuring approximately 4' deep, 9' high, and 20' long. The <br /> enclosure was framed with shop welded steel angles and covered with 3/4" thick plywood. The door was <br /> covered with plastic sheeting to prevent leakage of air pressure. At one end of the enclosure, a "Dwyer" <br /> Series 477 Digital manometer was attached to measure pressure inside the enclosure. Two duct fans were <br /> attached in series to the enclosure with flexible ducting to provide the positive and negative pressures. <br /> STRUCTURAL SOLUTIONS, P.A. <br />
