The ASTM E23 standard describes notched bar impact testing of metals according to Charpy and Izod.For the test, a notched metal specimen is broken in half using a pendulum hammer. The ASTM E23 standard describes the requirements for specimens, for the performance of the test, for result reports and for testing machines, i.e., pendulum impact testers at ambient .A widely used testing in the case of impact behaviour study is the Charpy and Izod impact test. It is a simple analysis method for the measurement of the stiffness by breaking a random geometry bar. 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 . A widely used testing in the case of impact behaviour study i s the Charpy and Izod impact test. It is a simple analysis method for the measurement of the stiffness by breaking a random geometry bar.
Main features of Izod Impact Testing The sample utilized for the tests is one similarity. Both tests employ notched specimens that are struck by a pendulum striker that is swinging. Frequently, the test object is a metal bar with a V-shaped notch. . Case Study In-depth examination of genuine material testing solutions.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. Izod impact testing determines the impact strength of materials. The test procedure, the application of izod testing, factors affecting impact energy, the ductile to brittle transition are all covered. . In the case of low temperature tests, specimens may are kept in a freezer until their temperature has equilibrated. They are then .

The Charpy impact test is carried out in a 3-point flexure setup.The Charpy specimen is centered on the supports in the pendulum impact tester and rests against two anvils. In the case of notched specimens, the notch faces away from the pendulum hammer and is placed exactly across from the point at which the hammer strikes the specimen..the right impact test equipment for standard-compliant testing! Impact testers help determine the failure behavior of materials or components under rapid loads and changing temperatures. Because many materials used for a number of different applications on a daily basis are subjected to fluctuating temperatures, and since the fracture or failure behavior also depends on .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. We used CEAST 9050 Impactor to do an Izod impact test on specimens made by extrusion-compression of PPS (powder matrix) and recycled carbon fiber blend (fiber lengths varied from 6.35 mm to 12.7 mm).
