Introduction:
When evaluating the toughness of materials, two commonly used methods are the Izod and Charpy impact tests. Though both serve a similar purpose, they differ in setup, orientation, and application.
Izod Test:
In the Izod test, the specimen is positioned vertically and clamped at one end. The impact is applied to the upper portion of the specimen. It’s widely used for plastics and polymers.
Charpy Test:
Conversely, the Charpy test uses a horizontally supported specimen with both ends resting on supports. The impact is delivered to the center, making it ideal for metals and structural materials.
Conclusion:
The primary difference between Izod and Charpy lies in the specimen orientation and application area. Understanding these differences helps manufacturers choose the right test for accurate material toughness evaluation.
