Abstract: A procedure is provided for evaluating the score, snap and edge appearance of wallboard panels, and includes scoring a wallboard panel with a knife at a constant and known force using a benchtop board scoring device; snapping the scored panel in a Universal Board Testing Machine to measure the breaking force, forming a snapped panel edge; measuring a cleanliness of the snapped panel edge by placing a straight edge against the snapped panel edge and measuring gaps between the snapped panel edge and the straight edge in a plurality of locations on a face of the panel, and a plurality of locations on a back of the panel; and averaging all of the measured gaps to create an Index Score.

Abstract: Embodiments of a system and a method for determining a surface smoothness of a facing specimen can be used in connection with the manufacture of products, including cementitious products such as gypsum wallboard, for example. Such systems and methods can be used to generate a composite smoothness factor based upon a measured mottle value and topography value using stochastic frequency distribution analysis.
