Please contact the Engineering Section of the TDI for the appropriate impact locations for each test specimen. If the door will be tested in accordance with Section 4.3.2 of TDI 1, then the door shall be impacted as shown in Figure 6A. Two out of three specimens must pass. If the surface area of the garage door is less than 75 sf, then the maximum allowable cycle time is 3 seconds. If the door will be tested in accordance with Section 4.3.2 of TDI 1, then the door shall be impacted as shown in Figure 8A. Two out of three specimens must pass. If the door will be tested in accordance with Section 4.3.3 of TDI 1, then two out three specimens must pass impacts as shown in Figure 8B and two out of three specimens must pass impacts as shown in Figure 8C. Horizontal lines indicate door section.
Vertical lines note vertical reinforcement.
If the door will be tested in accordance with Section 4.3.2 of TDI 1, then the door shall be impacted as shown in Figure 9A. Two out of three specimens must pass. The horizontal lines indicate door sections. The requirement in TDI 1-98 is that 2 out of 3 specimens must pass the impact and cyclic wind pressure loading tests. If the first two specimens successfully pass the impact and cyclic pressure tests, then the third unit may be omitted. Please consult with this FAQ or with the engineering section of the TDI for the appropriate impact locations on the test specimens.
