Abstract

An apparatus and process for testing a panel for strength and stiffness has the ability to handle panels of different thicknesses, and also has a temperature sensor so that panels can be tested hot and the cold end use strength and stiffness correlated. The apparatus moves the panel in an "S" shaped path through a series of rollers, and measures the load to deflect the panel a predetermined distance for different thicknesses of panels. An algorithm is used to correlate the cold end use strength and stiffness values from the temperature and loading figures.
