Standard Izod impact testing is defined by ASTM E23. Specific component testing requires specialty fixturing to adapt our
Pendulum Impact Testing machines, which are designed for compliance to ASTM E23 specifications, for
Izod applications. A typical impact test includes a specimen (component), an anvil for the application of Izod and/or Charpy fixturing, a pendulum of sufficient mass to break the test specimen placed in the swing path, and a mechanism to indicate absorbed energy.
Many of the our pendulum impact testers are equipped for Izod specimen testing. To apply Izod impact loading to a specific component, we chose the SI-1C3 Pendulum Impact Tester because it is configured for Izod capability (Charpy applications are also available with this versatile system). We suggest that sample pieces, along with detail drawings of the item, are provided for complete consideration of the fixture design for proper fit into the Impact tester. Fixturing is designed to function with the existing Izod striker in the pendulum and also to mount in the Izod portion of the anvil attached to the base.
Specialty fixturing can provide the impact energy values required to assist you in the design of your product. Impact energy values can be obtained from the mechanical dial or optional Fracta Software digital display of energy.
We recommend reading and reviewing ASTM E23 in order to fully understand the test set up, procedures, and results requirements.
