he examination of the tensile strength of paper as well as the splitting strength of a multiplex composite is only relevant for the assessment of the material behavior in the processing or loading process, if a dynamic measuring method is used. A pendulum impact tester simulates high shear stresses, which affect the fiber strength and inter-fiber bonds of the paper due to high process speeds and structural loads. This is why we speak of the Internal Bond Test according to Tappi 569 (Scott Bond Test). Contrary to the mechanical evaluation of the Scott Bond devices, the emco </ em> IBT works digitally and provides a wide range of adjustment and adjustment options.
