ISO 180 Charpy and Izod Impact ISO 179-1

CIT-01 Charpy and Izod Impact Tester

Application

Impact testing is a crucial method in materials science and engineering, used to assess a material’s ability to withstand sudden loading or impact forces. Among the various impact tests, the Charpy and Izod tests are widely employed to evaluate a material’s toughness and resistance to fracture. Both tests provide insights into the extent of plastic deformation the material can endure before facing failure.

While they share similarities, they also have key differences in their specimen configurations and testing procedures. Below are the main differences between the Izod and Charpy impact tests.

Differences Charpy Impact Testing Izod Impact Testing 

Materials Tested Metal, plastics, and composites

Types of Notches U-notch and V-notch V-notch only

Specimen Position Horizontally, notch facing away from pendulum Vertically, notch facing toward the pendulum

Striking Point Middle of the sample Upper tip of the sample

Specimen Dimensions 55*10*10mm 64*12.7*3.2mm (plastic) or 127*11.43mm round bar (metal)
