The aim of a bend test is performed to determine the mechanical properties of the material or to check the susceptibility to plastic deformation under bending force of steel products and to detect imperfections in welded joints.
The test consists in three-point bending of the specimen to the appropriate angle (usually 180o). The specimens after bending are observed for any discontinuities. The test parameters depend on the thickness, type of tested material and standards / regulations / specific Customer requirements.
Bend test is performed in compliance with:
- PN-EN ISO 7438
- PN-EN ISO 5173
