Standard Test Method for Bend Testing of Material for Ductility
This test method covers a semi-guided bend test for ductility of metallic materials by bending through a specified angle and to a specified inside radius of curvature. When complete fracture does not occur, the criterion for failure is the number and size of cracks found on the tension surface of the specimen after bending. Note 1-Exceptions to the provisions of these test methods may need to be made in individual specifications or test methods for a particular material. 1.2 The values stated in inch-pound units are to be regarded as the standard. SI values given in parentheses are for information only. Note 2-For additional information see American Welding Society Standard D1.1, Structural Welding Code, Steel. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
