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.Impact strengths are generally lower as compared to strengths achieved under slowly applied loads. Indian standard method of izod impact test consists of breaking the specimen by one blow from a swinging hammer under specified condition, a notched test piece is gripped vertically with the bottom of the notch in the same plane as the upper face of the grips.
Two tests are there for toughness test: Charpy Impact test; Izod impact test; Izod test: In the Izod test, the specimen is positioned like a cantilever beam i.e. one end is fixed and the other is free. At the center of specimen V notch is created to initiate crack. The notch angle of the Izod impact test specimen is 45° On the other hand, the Izod impact test is a standardized method for assessing the material’s ability to withstand impact forces, providing data on its toughness and durability under sudden loading conditions. . 10 mm thickness, with a 2 mm deep notch and a 45° angle. Charpy U-Notch: 55 mm length, 10 mm width, 10 mm thickness, with a 1 mm .
2. Izod The Izod impact test is similar to the Charpy test in that a weighted pendulum hammer strikes a test specimen containing a V-shaped notch. An Izod impact testing apparatus — which is essentially identical to a Charpy impact testing machine — is used to determine Izod impact strength.
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.The impact test calculator will help determine the energy absorbed by a notched material specimen. We perform impact tests to understand material failure behavior in dynamic conditions. . The test begins with the arm set to a high position at the angle of fall, .

Impact testing of plastics is performed using a notched Izod test, i.e. ASTM-D256-10. However, the notch in these specimens can be hard to manufacture with traditional tools. . The literature .
Explanation: ‘A’ is called the notch angle of a specimen. In an Izod test, the notch angle is 45°. The angle of the notch is an important factor in determining the reaction a material shows when the test is done on it. The notch in the sample is pressed to a depth of 5 mm with a sharp tool-steel chisel having an angle of 45 degrees. The resulting notch root radius is around 0.025 mm. One result of the test is the determination of the fracture appearance transition curve. . Izod impact test. Izod impact testing uses a sample with a V-notch which is similar .IZOD IMPACT: ASTM VS ISO There are two primary differences between the ASTM method and ISO method. TESTING STANDARDS FOR ASTM AND ISO • ASTM D256 – Standard Test Method for Determining the IZOD Pendulum Impact Resistance of Plastics. • ISO 180: Plastics – Determination of Izod Impact Strength of Rigid Materials.
A European standard called EN 10045 describes how to test metallic materials. Moreover, Charpy impact strength testing is intended to use this.
