The Izod and Charpy impact testers are both used to measure the impact resistance of materials, specifically metals and plastics. The Izod impact test involves striking a notched specimen with a pendulum.
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 .

The document describes an Izod impact test to determine the impact resistance of a notched steel bar . The Izod/Charpy Impact Tester is a commonly used instrument in material testing laboratories to measure the impact resistance of various materials, including plastics, metals, and composites. This testing method helps determine the toughness and durability of materials, making it an essential tool for quality control, research and development, and product .Impact test determines a very important quality of the test, i.e. ductility. Performing a Charpy test will give an estimate whether the metal is ductile or brittle. The way you are using Charpy impact tester determines the accuracy of the test results. There are some precautions that need to be taken while performing Charpy impact test.
ISO/R 84-1959( E) Izod impact test for steel. International Organization for Standardization BS 131: Part 1: 1961 Methods for notched bar tests, Part 1 The Izod impact test on metals. British Standards Institution. 0.4 In reporting .Two basic types of impact testing 1) Charpy impact test The specimen is supported as a simple beam with the load applied at the center. The position of latching tube is set to 140° The specimen is supported horizontally from two sides 2) The Izod test The specimen is supported as a cantilever beam. The position of latching tube is set to90°Izod Impact Test: Picture this as a classic duel. A single, notched specimen stands upright, bracing for the swing of a pendulum hammer. Think of it as the material’s last stand against the forces of destruction. The hammer swings down, hits the specimen, and the amount of energy absorbed during the break is measured. It’s a test of .The IZOD impact test requires different dimensions based on the material you use. For example, you need 64 x 12.7 x 3.2mm for plastic. On the other hand, 127 x 11.43mm is the dimension for a round metal bar.
Test methods used to measure Notched Izod Impact (or notch sensitivity) and Charpy Impact in plastics are: ASTM D256-10(2018) : Plastics — Determination of Izod pendulum impact resistance ISO 180:2019 : Plastics — Determination of Izod impact strength ASTM Standard E23 "Standard Test Methods for Notched Bar Impact Testing of Metallic Materials" describes procedures for Izod impact testing (with many similarities to and a few differences from procedures used in Charpy impact testing). The Charpy and Izod specimens have an identical cross section (10 mm by 10 mm) and an identical V notch . The Notched Izod Impact test is a single point test that measures a materials resistance to impact from a swinging pendulum. Izod impact is defined as the kinetic energy needed to initiate fracture and continue the fracture until the specimen is broken. The test specimen used in the Notched Izod Impact test are notched to prevent deformation of .construction. A modified impact test is also often carried out in the case of soft aggregates to find the wet impact value after soaking the test specimen. The allowable impact values in the dry'and wet conditions are given in Table 2.4. SI. No. 1 2 2.2.2 Apparatus The apparatus for the test comprises an impact testing machine, cylindrical measure,
The Izod / Charpy Impact Test represents a pivotal evaluation method in the material science industry, serving as a fundamental measure of a material's toughness and resistance to impact at varying temperatures. This testing methodology is critical for assessing the durability of plastics, metals, and ceramics under sudden stresses. Administered using .Before, during, and after impact test and tensile test, it is essential to follow safety precautions. Appropriate personal protective equipment (PPE) such as gloves, goggles, and earplugs should .
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. This test, on the contrary of Izod and What is an Izod / Charpy Impact Tester? The Izod and Charpy impact testers are both used to measure the impact resistance of materials, specifically metals and plastics. The Izod impact test involves striking a .Experiment: Mechanical Testing- Impact & Hardness Testing Objective The main objective of this experiment is to introduce two important basic mechanical property tests; hardness . For both Charpy and Izod, a V-notch is machined into a bar specimen with a square cross-section. A standard V-notch test apparatus is schematically illustrated in .Impact test. Measures the ability of a material to absorb a sudden application of a load without breaking. The Charpy test is a commonly used impact test. Lateral expansion. The lateral change in dimension of a Charpy impact specimen due to fracture. The dimension measured is the width opposite the v-notch (see Fig. 1-3).

Impact testing serves to assess a material’s impact toughness, representing its resistance to impact forces. The ability to quantify the impact property is a great advantage in product liability and safety. This involves three main tests: the tensile impact test, the Charpy V-notch test, and the Izod impact test.Material impact toughness can be measured by various types of test such as the Charpy V-notch impact test, Izod test or K IC test. The most commonly used test is the Charpy impact test (see Fig. 6.9), which gives an indication of the toughness of a material at a specified temperature.It is not a particularly accurate test but can give a general indication of the ability .
The Izod impact test is a type of test that measures the relative toughness of a material. Toughness in this context correlates to the material’s capacity to absorb energy. The Izod and Charpy tests are the standard methods for impact strength testing. Operators use a Pendulum impact testing machine to perform both tests.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.
