Izod impact is defined as the kinetic energy needed to initiate fracture and continue the fracture until the specimen is broken. Izod specimens are notched to prevent deformation of the specimen upon impact. This test can be used as a quick and easy quality control check to determine if a material meets specific impact properties or to compare .The most common impact tests are either Charpy or Izod. Charpy tests are implemented according to ISO 179-1 and ASTM D6110. Instrumented Charpy tests to ISO 179-2.Izod tests are performed according to ISO 180, ASTM D256, ASTM D4508 and "unnotched cantilever beam impact" to ASTM D4812. IZOD test is vertical while Charpy tests are horizontal but both measure impact resistance. The main difference lies within a notch sample orientation during testing where in an Izod notched bar impact test, the specimen stands vertically with its notch facing towards the pendulum whereas, during charpy v-notch impact test ,the samples are placed horizontally .Tensile impact test procedures. The tensile impact strength test was originally developed to overcome the deficiencies of flexural (both Izod and Charpy) impact test. All the test variables that have a high effect on the results, such as notch sensitivity, toss factor and specimen thickness, are eliminated in the tensile impact test.
In materials science, the Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain rate test which determines the amount of energy absorbed by a material during fracture.Absorbed energy is a measure of the material's notch toughness.It is widely used in industry, since it is easy to prepare and conduct and results can be obtained quickly and .An Izod Impact Resistance Tester or V-Notch Tester is a crucial laboratory testing instrument in material testing that provides valuable insights into the strength and durability of various materials. Its versatility, accuracy, and ability to simulate real-life conditions make it an essential machine for industries that rely on strong and .In a Charpy impact test to ISO 148-1, a notched metal specimen is severed using a pendulum hammer. For the test, the metal specimen is centered on the supports in the pendulum impact tester. The notch is exactly across from the point at which the pendulum hammer strikes the specimen. This impact test is used to determine the absorbed impact energy. The general steps to perform the Izod or Charpy impact test are as follows: Sample preparation: Cut a standardized specimen of the material to be tested, according to the relevant standard. The specimen should have a notch to create a stress concentration point where the fracture will occur during the test.
