OSHA 29 CFR
In this test, a 200 lb bag of lead shot, 12 inches in diameter, was placed on our skylight in the middle of the glass for 60 seconds. When the glass held firm, the weight was then lifted and dropped from 5 feet up, 13” from the edge of the glass. The bag bounced without penetrating the skylight.
ASTM Draft E06.51.25
After passing the difficult OSHA safety requirements with ease, we increased the load to 300 lbs, and dropped it from 3 feet above the glass a total of three times: in the center, on the corner, and at the edge of glass. Again, it bounced right off. The glass cracked, but the weight stayed on the top side, where it belongs.
Extreme Fall Protection
With expectations always rising, we went and put our skylight up against a test that doesn’t technically exist yet. It works like the other fall protection tests that we already passed with flying colors, but increases the weight to 600 lbs. Gently set on the glass, the weight fails to crack the glass. Not until it’s dropped from a three-foot height does the glass break, but the laminate holds fast and the skylight bears the full weight.
