Re: Field test of Clear View Glass Railings “Hercules Glass” guardrail panel
AET Project #: 05-20608
Dear Mr. Ruprecht,
This letter reports tests performed on Clear View’s Hercules Glass panel on April 21, 2020 by Clear
View and your agents at 1141 120
th
Street in Roberts, Wisconsin. These tests were the first of a series
of tests that included the dynamic loading test described below, and vertical and horizontal static tests.
All tests were performed to provide test data that the panels meet International Building Code (IBC)
requirements.
The panel tested was a 13mm thick tempered and laminated glass panel with the brand name Hercules
Glass. It measured 13mm thick x 39.37” tall x 60” wide, and is supported by two metal “spigots”, each
located 12” inside a side edge of the panel (spaced 36” apart). The panel are secured in slots within the
spigots, and the spigots are bolted to the supporting structure. The total height of the panel and spigots
is 42”.
The dynamic testing involved hanging 300# sandbags against the side of the panel at the panel’s top
edge. The sandbags were pulled back 33” and released, causing the sandbags to swing into the top of
the panel, simulating a dynamic horizontal guardrail load – a person or object falling into the panel.
The panel deflected approximately 4” and returned to its original shape, without experiencing any
damage.
Don’t hesitate to contact us with questions about this testing or any other aspects of this evaluation
program.
Sincerely,
American Engineering Testing, Inc.
