1. Air Infiltration Test: Not exceed 0.10 cubic feet per minute per foot of crack length when tested at a pressure of 6.24 psf.

Perform tests in accordance with ASTM E 283 with the sash in a closed and locked position.

2. Water Resistance Test: Subject window unit to a water resistance test in accordance with ASTM E 331 and E547 with no water passing the interior face of the window frame and no leakage as defined in the test method. Mount the glazed unit in its vertical position

08 51 13 - 3 continuously supported around the perimeter and the sash placed in the fully closed and locked position. When a static pressure of 12 pounds per square foot has been stabilized, apply five gallons of water per square foot of window area to the exterior face of the unit for a period of 15 minutes.

3. Uniform Load Deflection Test: ASTM E 330 at 95 pounds per square foot: No member deflection more than 1/175 of its span.
