Equipment designed to perform standard notches on samples, which are subsequently subjected to mono-axial impact resistance tests, according to the CHARPY and IZOD procedures.it is suitable for concentrating stress, minimizing plastic deformation, and directing fracture to the part of the specimen behind the notch. The dispersion in energy at break is thus reduced. However, due to differences in the elastic and viscoelastic properties of plastics, the response to a given notch varies between different materials. It is possible to simultaneously notch up to 3 grouped specimens, naturally depending on the plastic material and its characteristics
