Metallic materials; Tube (in full section); Bend test

This standard establishes a unified test method for assessing the ductility and soundness of metallic pipes by subjecting a full cross-section of the specimen to bending. The procedure involves placing the pipe segment over a supporting anvil and applying a downward force via a bending tool until a specified deflection or deformation is achieved. By evaluating the material's behavior under this stress, the test determines its ability to withstand bending without cracking or failing, which is critical for applications involving structural integrity and safety. The methodology ensures consistent results across different laboratories by defining precise parameters for specimen preparation, support dimensions, and loading rates. It serves as a fundamental reference for manufacturers and quality control personnel to verify that pipe products meet required performance criteria regarding flexibility and resistance to deformation. The standard outlines detailed steps to execute the bending process, including visual inspection of the deformed section for defects. This approach provides a reliable means to compare material qualities and ensure compliance with engineering specifications without requiring destructive testing of the entire production batch.
