Although, the principle on which these 2 methods of testing impact resistance work is the same, still, they are different in many ways. Here, in this brief article, we are going to have a look at all the differences these methods have. It is a standard testing method that is used to measure the impact resistance of a material.
During the test, the pendulum is released from a specific height. Note : You can read here in detail about the Charpy Test — What is it and what is involved in it? We hope this brief article on the difference between Izod and Charpy Impact Test has helped you deeply understand the differences between these two testing methods.

Thursday, November 4, In the Izod method, the test material was placed in a vertical position, while in the Charpy method, the test material was placed horizontally. The notch in the izod test is facing the striker, fastened in a pendulum, while in the charpy test, the notch is positioned away from the striker.
In the Charpy method, there are two kinds of notches, the V-notch and the U-notch, while in the Izod method, there is only one kind of notch.

You agree that we have no liability for any damages. One of the main differences from Charpy impact is that Izod impact testing can be performed on either plastic or metallic specimens. Plastic samples are typically a 64 x Metallic samples are typically round x While both the Izod and Charpy methods measure similar properties, the specimen design and testing configuration are different enough that care should be taken when choosing with method to perform.
Your testing provider should be able to provide method recommendations based on your end goals and specific material in question. Should you decide to perform Izod impact, you will need to decide on which specimen configuration to use. There are varying configurations of round specimens versus square specimens and single notched specimens versus those with up to three notches. Since it is often required to average 3 results for impact testing, the 3 notch specimen could be more economical, as it will take less material to get three impact results.
Another possible advantage of the 3 notch sample is that the final result can be an average of directions depending on the specimen configuration. This could help eliminate bias caused by directional properties if this is a concern for your material.
