*loads can be affected by temperature, humidity, time, & other
environmental factors. Users should test shelves in appropriate
environment. It is assumed that deflection greater than 1/4" is
undesirable aesthetically even though rupture has not occurred.

* Screw pull-out can be affected by temperature, humidity, time, and
other environmental factors. In addition, dynamic forces are more severe
and require substantial safety factors. Users should test under the
worst anticipated conditions. |
