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 ) verifying Charpy impact machines (see ), optional test specimen configurations (see ), precracking Charpy V-notch specimens (see ), designation of test specimen orientation (see ), and determining the percent of shear fracture on the surface of broken impact specimens (see ). In addition, information is provided on the significance of notched-bar impact testing (see ), methods of measuring the center of strike (see ), and the availability of Charpy V-notch verification specimens (see ).

1.2 These test methods do not address the problems associated with impact testing at temperatures below -196°C (-320°F, 77 K).
