Structural Performance Test Report

LABORATORY CERTIFICATION NO: 94-0323-47 TEST SPECIMEN: Eight (8) 40" wide by 40" high Fixed Lites Using Various Attaching Methods on Glass Surfaces. TEST SPECIFICATION: ASTM E 330-93, "Test Method for Structural Performance of Exterior Windows, Curtain Walls and Doors by "Uniform Static Air Pressure Difference". TEST SPECIMEN DESCRIPTION The specimens tested measured 40" wide by 40" high overall. Each specimen was constructed of polyvinylchloride (PVC) surround members (CertainTeed Bottom Sash Frame) with welded mitered corner construction. The specimens used 3/32" clear annealed glass that was exterior drop in glazed using an adhesive tape back bedding and a dual durometer glazing bead. The following results were obtained. Specimen No. 1 Test Results (no film)   Title of Test PSF (mph) Results Exterior Uniform Structural Load 30 psf (108 mph) Pass 40 psf (125 mph) Pass 50 psf (139 mph) Pass 60 psf (153 mph) Pass 70 psf (165 mph) Pass 80 psf (177 mph) Pass 90 psf (188 mph) Pass 100 psf (See Note No. 1) Note No. 1: At 98.8 psf (196 mph) the glass shattered.     Specimen No. 2 Test Results (film over viewing area only)   Title of Test PSF (mph) Results Exterior Uniform Structural Load 50 psf (139 mph) Pass 90 psf (188 mph) (See Note No. 2) Note No. 2: At 72.8 psf exterior pressure the glass shattered but stayed in the confines of the frame. Reapplied pressure and at approximately 60 psf the glass edge deglazed from adhesive tape back bedding. (glass surface remained bonded by the film). Special Note: At this point in testing it was decided to take the specimens directly to failure.     Specimen No. 3 Test Results (silicone bead at interior perimeter)   Title of Test PSF (mph) Results Exterior Uniform Structural Load 74.3 psf (170 mph) (See Note No. 3) Note No. 3: At 74.3 psf exterior pressure the glass shattered. At this point 2 mil. plastic was applied over exterior surface to seal any openings and the load was reapplied. Result: At 28.6 psf the glass deglazed from adhesive tape back bedding at the top rail.     Specimen No. 4 Test Results (clear poly tape bridging the exterior frame perimeter)   Title of Test PSF (mph) Results Exterior Uniform Structural Load 90.4 psf (188 mph) (See Note No. 4) Note No. 4: At 90.4 psf exterior pressure the glass shattered and deglazed from frame at the right stile.     Specimen No. 5 Test Results (clear poly tape bridging the interior frame perimeter and capped with #1 silicone)   Title of Test PSF (mph) Results Exterior Uniform Structural Load 78.0 psf (175 mph) (See Note No. 5) Note No. 5: At 78.0 psf exterior pressure the glass deglazed from left stile corner to midspan of the top rail.     Specimen No. 6 Test Results (Identical to No. 5 only using #2 silicone cap)   Title of Test PSF (mph) Results Exterior Uniform Structural Load 104 psf (202 mph) (See Note No. 6) Note No. 6: At 104 psf exterior pressure the glass shattered but remained employed in the surrounding members. Stopped test at 187 psf (270 mph) no deglazement observed.     Specimen No. 7 Test Results (Standard OEM)   Title of Test PSF (mph) Results Exterior Uniform Structural Load 88 psf (185 mph) (See Note No. 7) Note No. 7: At 88 psf exterior pressure the glass deglazed at the top rail.     Specimen No. 8 Test Results (Standard OEM)   Title of Test PSF (mph) Results Exterior Uniform Structural Load 60 psf (153 mph) (See Note No. 8) Note No. 7: At 60 psf exterior pressure the glass deglazed at the top rail.   Conclusion: In each case the film applied to the glass held the glazing surface intact. Each test that failed resulted in a deglazement failure from back bedding.
