Perpendicular Tensile STrength

    Essentially this is a test to determine  how well the panel is glued together.  It is typically referred to as internal bond in industry.  The standard way for performing this test is by using a test specimen that is 2 inches square and is pulled apart perpendicular to the faces of the board.  This parameter is typically reported in pounds per square inch or pascals upon failure of the board.
