The Class J – Charpy and Izod Automatic Impact Testing System for the Izod Test provides a specified distance from the axis of support to the center of percussion, which is measured at 335 mm. This distance is a critical parameter in the Izod Test as it determines the leverage and moment of the pendulum when it strikes during impact. By setting the distance to 335 mm, the testing system ensures consistent and reliable test results for assessing materials’ impact resistance and strength.

The distance from the axis of support to the center of percussion is a critical factor in properly simulating real-world impact scenarios and evaluating materials’ ability to withstand sudden external forces. It plays a significant role in determining the energy transfer and fracture behaviour of test specimens. Therefore, by maintaining a precise distance of 335 mm, the Class J – Charpy and Izod Automatic Impact Testing System ensures accurate and standardized Izod Test measurements.
