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 ), designation of test specimen orientation (see Terminology ), and determining the shear fracture appearance (see ). In addition, information is provided on the significance of notched-bar impact testing (see ), and methods of measuring the center of strike (see ).
1.2 These test methods do not address the problems associated with impact testing at temperatures below –196 °C (77 K).
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3.1 Exception—Section and provide inch-pound units for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section .
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
