Pendulum Charpy/Izod Impact Testing is a high strain-rate test to determine the amount of energy absorbed by a material during fracture.The Impact tester involves a pendulum of known mass and length which is dropped from a known height to strike an Impact Specimen. Impact specimens are of standard or subsize dimensions that can be found in a variety of industry standards including ASTM E23, ASTM A370, EN 10045-1 and ISO 148. Various strikers and specimen vises are available to suit all requirements of Charpy or Izod Testing. Specimens are notched using a broaching machine to specific dimensions and geometries. The energy transferred to the material after impact can be inferred by comparing the change in height of the hammer before and after striking the specimen.
Class J is widely used for lzod and Charpy impact test on softer metals, plastics and rubber specimens. Equipped with tensile impact pendulum and fixtures, it can carry on tests on plastic film and sheet. The newly enhanced design offers the most cost-effective configuration to address Charpy test from 1J to 50J, and lzod test from 1J to 22J.
GenNotch 2000 is the industry leading motorized lzod and Charpy impact test notching and broaching system for plastic specimens.
