a. When tested in accordance with ASTM E283, the air infiltration at 6.24 psf
must not exceed 0.06 cfm per square foot of wall area.
2. Static Water Infiltration:
a. When tested at a differential static pressure of 15.0 psf for 15 minutes, in
accordance with ASTM E331, any uncontrolled water passing into the roomside
beyond the interior barrier of the wall system shall not be permitted. The
panel system shall be designed to provide controlled drainage to the exterior
face of the wall for any leakage of water occurring at joints and/or
condensation taking place within the wall system.
3. Dynamic Water Infiltration:
a. Shall be tested in accordance with AAMA 501 with a slipstream velocity,
creating a pressure on the wall equivalent to 15.0 psf with a water spray rate of
5 gallons per hour per square foot for 15 minutes with no uncontrolled water
leakage to the room-side.
4. Structural Performance:
a. Shall be tested in accordance with ASTM E330 at design pressure. Deflection
limitations are listed previously. After initial test, test at 150% of design
pressure; no permanent deformation exceeding L/1000 or failure to structural
members allowed.
5. Seismic Racking:
a. There shall be no failure or deterioration of the system when the unit is laterally
racked to 3/4” in both directions and repeated for three (3) cycles. System
must pass the static water requirements as described in the Static Water
Infiltration Section 1.05 A 2, following the seismic racking.
C. Bond Integrity Test: In accordance with ASTM D 1781-76 for bond integrity, simulating
resistance to delaminating (No other test procedure is acceptable):
1. Peel strength: 22.5 in lb/in (min)
D. Fire Performance:
1. ASTM E84-79 - Maximum value flame spread 0, smoke developed 0.
2. UBC 17-5 - No flame spread along interior face or penetration through the wall
assembly.
3. ASTM 162 - No surface flaming.
1.06 PRODUCT HANDLING
A. After acceptance of panels on a given elevation, protection shall be the responsibility of the
General Contractor.
