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 an automatic Charpy and Izod impact testing system for low-energy impact evaluation of plastics and related materials. It covers 1–50 J for Charpy tests and 1–22 J for Izod tests, with interchangeable pendulums, adjustable spans, controlled striking velocity, and ASTM D6110, ASTM D1822, ISO 179, GB/T 1043, and ISO 9854.1 support for standardized testing.
GenNotch 3000 is a motorized multi-specimen notching and broaching machine for preparing plastic specimens before Charpy and Izod impact testing. It holds up to 20 samples and can process 60 specimens in about 10 minutes, helping laboratories improve throughput. Adjustable feeding, controlled knife movement, ASTM D256, ASTM D6110, ISO 179, and ISO 180 compliance support consistent, standards-ready notches.
