The impact test is a standardized method for analyzing the toughness or brittle-fracture sensitivity of a material. The specimens are notched with a standardized notch-cutting machine. The (notched) impact value is defined as the energy lost per unit of specimen area (at the notch) in kJ/m2.

With the impact-tester is how we test the strength of a material. “If you accidentally drop your Child's toy on the ground, you don’t want it to break. A Charpy impact test can be performed on polymer materials to analyze mechanical properties. These properties are very important when it comes to designing and producing common polymer products such as toys”.
