B. Design Requirements: Comply with structural performance, air infiltration, and water penetration indicated in AAMA/WDMA 101/I.S. 2-97 for type, grade, and performance class of window units required.
C. Testing: Test each type and size of required window unit through a recognized Independent Testing Laboratory or Agency, in accordance with ASTM E283 for air infiltration, and with ASTM E331 for water penetration.
1. Air Infiltration: Exterior windows will not exceed 0.10 CFM per lineal foot of sash crack when tested in accordance with ASTM E 283-99 at a uniform pressure of 6.24 PSF.
2. Water Resistance: No water leakage will occur when windows are tested in accordance with ASTM E 331-00 at a static pressure of 10.00 PSF.
3. Uniform Load Deflection Test: No glass breakage, permanent damage to fasteners, hardware parts, or damage to make window inoperable or deflection of any unsupported span (meeting rails, muntins, frames, mullions, or other appurtenances) in excess of L/175 at both a positive and a negative load in minimum of 55 PSF when tested in accordance with ASTM E330-97.
4. Uniform Structural Load: Unit is to be tested at 1.5 x design wind pressure, both positive and negative at 82.50 PSF in accordance with ASTM E 330-97. There shall be no glass breakage, permanent damage to fasteners, hardware parts or any other damage to make the window inoperable. There shall be no permanent deformation of any main frame or sash member in excess of 2% of its span.
