Abstract
An apparatus for testing panel products in edgewise shear in which the shear stress is applied in a diagonal direction with a first rotational degree of freedom in a first grip means and a second rotational degree of freedom in a second grip means as a first loading configuration. A second loading configuration is provided in which the second rotational degree of freedom of the second grip means is locked in place and motion is prevented. A third preferred method of loading is available in which shear forces in a horizontal direction through a centerline of a specimen, with the centerline in the plane of the specimen and extending across a widest dimension of said specimen. Control and data collection are under computer control and operator safety is enhanced by a locking guard door which is electrically locked while the various parts of the machine are in motion.
