This document specifies a method for making transverse root, face and side bend tests on test specimens taken from butt welds, butt welds with cladding (subdivided into welds in clad plates and clad welds) and cladding without butt welds, in order to assess ductility and/or absence of imperfections on or near the surface of the test specimen. It also gives the dimensions of the test specimen. In addition, this document specifies methods to be used instead of transverse bend tests with a former for heterogeneous joints when base materials, heat affected zones and/or weld metal have a significant difference in their physical and mechanical properties in relation to bending. Guided transverse bend tests with a roller and longitudinal bend tests are alternative methods of testing for heterogeneous assemblies. This document applies to metallic materials in all forms of product with welded joints made by any welding process.
