"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 m.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).The Instron CEAST 9050 impact pendulum enables to determine the impact resilience of plastics and composites, easily and safely. The Instron CEAST 9050 impact pendulum tests comply with all the main ISO and ASTM impact testing methods, ranging from 0.5 - 50J and including Charpy, Izod and Tensile Impact.
Many notched bar impact tests of different designs and loading have been used to predict brittle fracture of ferritic steels. In the USA, the Charpy specimen has been standardized in ASTM E23 for impact three-point bend testing (ASTM E23 1999).Figure 1 illustrates a standard ASTM type A Charpy impact test specimen. The Charpy three-point bend specimen is more convenient . The quality of the data developed by pendulum impact machines depends on how well the machines are installed, maintained, and verified. This is the reason that ASTM Standard E23 Standard Test Methods for Notched Bar Impact Testing of Metallic Materials specifies annual direct and indirect verification tests.manual errors. •When performing pendulum impact tests, accurate energy values can only be achieved with a system made of a robust monolithic structure and a precise non-contacting magnetic encoder able to ensure zero friction. • Safety guards, both for manual and motorized versions, prevents unwanted access to the test area
Class J Impact Testing System is widely used for lzod and Charpy impact test on plastics and rubber specimens.
