Notched Bar Impact Testing of Metallic Materials ASTM E23-18

Notched Bar Impact Testing of Metallic Materials ASTM E23-18

ASTM E23 methods describe notched-bar impact testing of metallic materials by the simple-beam test (Charpy) and the cantilever-beam test (Izod). This method gives the requirements for test specimen, procedure, reports, Charpy impact machine verification, determining the shear fracture appearance, etc. The values stated in SI units are regarded as standard.


    ASTM E23 predicts the likelihood of brittle fracture accurately. The Charpy V-notch (CVN) impact test has been used widely in mechanical testing steel products, procurement specifications, and research for almost three decades. These test methods of impact testing are helpful specifically to the behavior of metal when it is 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 low or high temperatures.


    In ASTM E23, a suitable specimen (as the specimens of several different types are recognized), a set of anvils, and specimen supports on which the test specimen is placed to obtain the blow of the moving mass, a moving mass that has adequate energy to break the specimen placed in its pathway, and an indicating device for measuring the absorbed power of the broken specimen.

    Specimen size

    The sample’s length, width, and thickness should be 55 mm, 10 mm, and 10 mm, respectively.


    The absorbed energy values above 80% of the range capacity are inaccurate and shall be reported as approximate.
