Impact testing is a destructive mechanical testing method that measures a samples's ability to resist high-rate loading or absorb the energy of a dynamic impact. In impact testing, a pendulum arm is held at a specific height and then released to hit and break the sample. Its impact strength is determined from the energy absorbed by the sample. The most common method is the Charpy impact test, or Charpy v-notch test, still widely used in industry after more than 100 years in practice, and associated with the standard ASTM A370. Another type of impact test is Izod impact strength testing, most often associated with ASTM D256.
