1) The test notches for the impact specimens for the tests have different dimensions. The Izod test is a V-notch; the Charpy test has three different specimen types: Key-hole, U-notch, and V-notch. However, other specimen types may be specified as required for both tests.
2) The specimens are held differently. The Izod specimen is held in a cantilevered manner; the Charpy test is held such that the specimen rests against two supports on either side of the test notch.
3) The impact location is different. The Izod test impact is against the end of the exposed cantilever; the Charpy test is struck directly behind the test notch such that the specimen undergoes three point bending.
4) The test specimens have different dimensions. The basic Izod test specimen is 75 x 10 x 10mm (2.95" x 0.394" x 0.394"); the basic Charpy test specimen is 55 x 10 x 10mm (2.165" x 0.394" x 0.394")
It's really a stretch to give 4 points of difference, particularly as these tests may be altered as required depending on the material performance characteristic being investigated.

Difference between izod and charpy test?
Both Izod and Charpy tests are used to measure the impact strength of materials, but the main difference lies in the direction of the impact force. The Izod test involves a single impact from a swinging pendulum on a notched specimen, while the Charpy test involves a swinging pendulum striking a notched specimen in a horizontal position. Charpy tests are more common due to their simplicity and reproducibility, but both tests provide valuable information about a material's toughness.
What are diffrant technique of raw material testing of polymer?
1) UTM- UTS 2) Impact - Izod / Charpy 3) HDT 4) VST 5) Flexural 6) Chemical resistance 7) Material identification - FTIR 8) Tg, Tm etc
How do you convert impact energy into impact strength?
Impact energy refers to the amount of energy absorbed by an object upon impact, while impact strength measures the ability of a material to withstand impact without fracturing. To convert impact energy into impact strength, you would typically need to perform material testing to determine the material’s resistance to impact forces and how much energy it can absorb before fracturing. This involves conducting impact tests such as Charpy or Izod tests to quantify the impact strength of the material.

What is the notch angle in izod impact test.?
45 degree angle
What is Izod's population?
Izod's population is 10,000.
When was Izod created?
Izod was created in 1938.
When was Izod Center created?
Izod Center was created in 1981.
What are the purposes of izod test?
The Izod test is used to evaluate the impact resistance of materials, particularly polymers and composites. It helps determine the amount of energy required to break a notched specimen under a single impact blow. This test is crucial for assessing material toughness and determining if a material is suitable for specific applications.
