A pendulum impact testing machine is used to determine the impact strength or toughness of a material under impact loading by measuring the amount of energy the material is able to absorb.

Understanding a material’s energy absorption properties is critical in predicting how much plastic, or permanent, deformation the material will be able to withstand before failure and is an important consideration in research and development applications as well as for quality control and material acceptance purposes.

The base components of a pendulum impact tester are the machine frame, a weighted pendulum rod with hammer, a dial gauge, specimen supports, and a safety shield/device. Complete pendulum impact systems can also include PC equipment and temperature conditioning devices.
