The Izod impact test consists of a pendulum with a determined weight at the end of its arm swinging down and striking the specimen while it is held securely in a vertical position [11]. The V-notch maker and impact test machine are displayed in Fig. 1.4 [8]. Charpy Testing machine perform test on metals as well as on polymers, ceramics as well as composites and is commonly used for evaluating relative toughness/impact toughness of materials.

Computing Uncertainty for Charpy Impact Machine Test Results. Izod Impact Test: In the Izod impact test, the test piece is a cantilever, clamped upright in an anvil, with a V-notch at the level of the top of the clamp. The test piece is hit by a striker carried on a pendulum which is allowed to fall freely from a fixed height, to give a blow of 120 ft lb energy. After fracturing the test piece, the height, 2.

    IMPACT TEST REPORT. Izod Impact Testing (Notched Izod) ASTM D256, ISO 180 is a common test to understand notch sensitivity in plastics. Scope: Notched Izod Impact 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, 55mm long, standard Charpy test specimen is given in Figure-2. If the dimensions of specimens are maintained as indicated in standards, notched-bar impact test results are affected by the lattice type of materials, testing temperature, thermo-mechanical history, chemical composition of materials, degree of strain hardening, etc..

A pivoting arm is raised to a specific height (constant potential energy) and then released.The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the sample is calculated from the height the arm swings to after hitting the sample.

    The MPM Charpy/Izod 9000 Series impact test machines can be used with pendulums in the 100 ft-lb to 700 ft-lb energy capacity range. Since the machine frame has been designed for up to 700 ft-lbs, any lower capacity can be accommodated. Therefore, you can upgrade your machine capacity later by purchasing a higher capacity pendulum without the need to buy an entire test machine. MPM will The absorbed energy of a test material, measured using a Charpy impact machine, is often reported as the mean absorbed energy of a set of specimens. However, the sample mean does not account for known sources of bias, including machine bias, which can be substantial. We address the estimation of a test result for the case in which the test

    The impact hammer that is used is specific to Izod testing and is different than the Charpy hammer. Since plastics have relatively low impact strength, a benchtop impact tester can be used. Our table top impact testing machines are capable of testing with between 1-25 Joules.
