1.1 These test methods describe notched-bar impact testing of metallic materials by the Charpy (simple-beam) test and the Izod (cantilever-beam) test. They give the requirements for:test specimens, test procedures, test reports, test machines (see Annex A1) verifying Charpy impact machines (see Annex A2),optional test specimen configurations (see Annex A3), desig-nation of test specimen orientation (see Terminology E1823),and determining the shear fracture appearance (see Annex A4).In addition, information is provided on the significance of notched-bar impact testing (see Appendix X1), and methods of measuring the center of strike (see Appendix X2).
