*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.
