Exterior window and door assemblies shall be tested in accordance with ASTM E330 or TAS 202 (HVHZ shall comply with TAS 202). Exterior window and door assemblies containing glass shall comply with Section 2403. The design pressure for testing shall be calculated in accordance with Chapter 16. Each assembly shall be tested for 10 seconds at a load equal to 1.5 times the design pressure.
Exceptions:
- Door assemblies installed in nonhabitable areas where the door assembly and area are designed to accept water infiltration need not be tested for water infiltration.
Door assemblies installed where the overhang (OH) ratio is equal to or more than 1 need not be tested for water infiltration. The overhang ratio shall be calculated by the following equation:
OH ratio = OH Length/OH Heightwhere:
OH Length = The horizontal measure of how far an overhang over a door projects out from the door's surface.
OH Height = The vertical measure of the distance from the door's sill to the bottom of the overhang over a door.
- For window and door assemblies tested in accordance with this section, structural wind load design pressures for window and door assemblies other than the size tested in accordance with this section shall be permitted to be different than the design value of the tested assembly provided such different pressures are determined by accepted engineering analysis. All components of the alternate size assembly shall be the same as the tested assembly except for length. Where engineering analysis is used, the glass shall comply with Section 2403.
