Description of Test Specimen: A 16' -0" wide x 7 high residential steel sectional garage door, one (1) section wide by four (4) sections high, each section being 2" inches thick by 21` high galvanized steel sheet. The door sections were connected together with one (1) 14 gauge galvanized steel end hinge at each end stile and one (1) 14 gauge galvanized steel center hinge at three ofthe interior stiles as shown on the drawing. Garage door Model No. 600 manufactured by Amarr Garage Doors was used in the test. The test units are further described on drawing IRC- 6016- 120 -15. The sections were reinforced as follows: November 7, 2002 Test: The bottom three sections were reinforced with two (2) 3" x 20 gauge galvanized steel struts located at the top and bottom of each section; the top section was rca tweed with one (1) 3" x20 gauge galvanized steel strut looted at the center of the section; May 25, 2005 Test: Each section was reinforced with two (2) 3" x 20 gauge galvanized steel struts located at the top and bottom of each section. The top section contained long panel glazing. Manner of Testing: The specimen was tested for static pressure structural performance in substantial conformance with the procedures described in DASMA 108 "Standard Method for Testing Sectional Garage Doors - Determination of Structural PerfornumceUnder Uniform Static Air Pressure Difference ", and ASTM E330 "Standard Test Method for Structural Performance of Exterior Windows, Curtain Walls, and Doors by Uniform Static Air Pressure Difference". Bath positive and negative pressures were tested. The specimen was installed in an enclosure measuring approximately 4' deep, 9' high, and 20' long. The enclosure was flamed with shop welded steel angles and covered with 3/4' thick plywood. The door was covered with plastic sheeting to prevent leakage ofair pressure. At one end of the enclosure, a " Dwyer" Series 477 Digital manometer was attached to measure pressure inside the enclosure. Two duct fans were attached in series to the enclosure with flexible ducting to provide the positive and negative pressures. Test Pr+oc dure• The specimen was subjected to the above pressures for the following durations. Positive pressure was applied on the exterior face ofthe door first, and then negative pressure was applied. Step 1: Preload the door to 50% of the Design Pressure and hold for 10 seconds. Step 2: Unload the door for 1 to 5 minutes. Step 3: Load the door to 100% of the Design Pressure and hold for 60 seconds. Step 4: Unload the door for 1 to 5 minutes. Step 5: Load the door to 150% of the Design Pressure (which equals 100% of the Test Pressure) and hold for 10 seconds. Step 6: Repeat I through 5 above for negative pressure. Observations: No failures occurred as a result of the noted loadings. The door remained operable after both positive and negative tests. The 16' x 7' Model 600 as described on Drawing IRC- 6016 - 120 -15 meets or exceeds the testing criteria as described above. By comparison ison to the construction of the 16' x 7' Model 600, the following doors also meet or exceed the above testing criteria, when constructed in accordance with Drawing IRC -6016- 120 -15: • 16' x T Model 950 doors (which are constructed of thicker 24 gauge steed in lieu of 25 gauge steel) • 10' to 16' wide Model 600, 650 and 950 doors with heights of 6'-6" through 14' -0" • 16' x 7' Model 950 glazed long panel doors (which are constructed ofdrick r 24 gauge steel in lieu of 25 gauge steel) • 15'-6" i, _ ' -0' wide Model 600, 650 and 950 glazed long panel doors with heights of 6'-6" through 14' -0" Subnu , .
