Abstract
An improved measurement method and a corresponding measurement device are provided that measure the edge strength of plate-shaped elements made of brittle-fracture material. For this purpose, a long sample is drawn apart at the short edges, wherein the force transmission points lie next to the center of gravity of the base surface of the sample.
