ISO 8491:1998 PDF

Overview

ISO 8491:1998 is an international standard published by the International Organization for Standardization (ISO) that specifies a bend test method for metallic tubes in full section. Specifically aimed at metallic tubes with circular cross-sections and outside diameters up to 65 mm, this standard provides a clear procedure to assess the ductility and plastic deformation capacity of tubes when subjected to bending forces. The bend test is critical for verifying tube quality and structural integrity in manufacturing and industrial applications.
