These tests, pivotal in determining the toughness of .
An Izod impact testing apparatus — which is essentially identical to a Charpy impact testing machine — is used to determine Izod impact strength. The primary differences between the Izod and Charpy impact tests are the size of the test specimen, how it is restrained, and which side is struck by the pendulum hammer.Impact test. Measures the ability of a material to absorb a sudden application of a load without breaking. The Charpy test is a commonly used impact test. Lateral expansion. The lateral change in dimension of a Charpy impact specimen due to fracture. The dimension measured is the width opposite the v-notch (see Fig. 1-3).Impact Testing Through IZOD or Charpy Test. . For the IZOD test, the dimension for the specimen is 75 x 10 x 10mm. On the other hand, the dimension for the specimen for the Charpy test is 55 x 10 x 10. Hammer Type; In both tests, a hammer is used as a striker. In the IZOD test, it is a farming hammer whereas the Charpy test is followed by the .
Izod impact is defined as the kinetic energy needed to initiate fracture and continue the fracture until the specimen is broken. Izod specimens are notched to prevent deformation of the specimen upon impact. This test can be used as a quick and easy quality control check to determine if a material meets specific impact properties or to compare .
