Impact Tester
Impact resistance is a material’s ability to absorb kinetic energy during a rapid impact without fracturing. In polymers, this property is critical in all applications where the component is exposed to impacts, drops, or sudden dynamic loads: from industrial packaging to automotive components, from construction to medical devices. The most common methods for measuring fracture energy are the Charpy test (ISO 179) and the Izod test (ISO 180), both based on the pendulum principle: a hammer of known mass is released from a defined height and strikes the specimen; the residual energy after fracture allows the energy absorbed by the material to be calculated. Tensile impact strength (ISO 8256) is a variant in which the specimen is subjected to dynamic tensile loading rather than bending. The results are expressed in kJ/m or kJ/m², and are influenced by the specimen’s geometry, the presence or absence of a notch, and the test temperature.
