1) The maximum allowed reaction 2) Value derived from shear testing a PSM80 panel 3) Value derived from flexural testing the given panel. Larger values possible via shear testing. Contact manufacturer for information. 4) Allowable Applied Load is the total load, not including the self-weight of the panel, that can be applied to the panel 5) Total Allowable Applied Load is the total load, including the self-weight of the panel, that can be applied to the panel
