Charpy Notched Bar Impact Testing of Metallic Materials

$125.00

Determine a material’s toughness, brittleness and ductility.

ASTM E23 – 18 Standard Test Methods for Notched Bar Impact Testing of Metallic Materials

ISO 148-1, 148-2 Charpy V-Notch Testing

Determine the ductility of a material and measure a given material’s notch toughness.

These test methods of impact testing relate specifically to the behavior of metal when subjected to a single application of a force resulting in multi-axial stresses associated with a notch, coupled with high rates of loading and in some cases with high or low temperatures. For some materials and temperatures the results of impact tests on notched specimens, when correlated with service experience, have been found to predict the likelihood of brittle fracture accurately.
