EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 63114 testing. IEC EN 63114 describes the general principle and technical details of the reverse bending test method used to evaluate the ductility of electrical steel strip and sheet. This test method can be applied to Epstein test strip specimens obtained from any grade of non-directional and grain-directional electrical steel. Test specimens should not be annealed.
Prior to the preparation of this standard, the working group discussed the industry's actual situation regarding the application of reverse bending tests to evaluate the ductility of electrical steel strip and sheet, including non-oriented and grain-oriented materials.
This standard describes the general principle and technical details of backbend testing specifically for the evaluation of ductility of electrical steel according to two modes, Mode A according to ISO 7799 and Mode B according to ASTM A720 and JIS C2550.
Apply the reverse bend test to a sample of Epstein test strips and get the bend count as an assessment of the ductility of the electric steel strip and sheet.
According to different electrical steel standards, the test specimen should be cut with its longitudinal axis perpendicular to the rolling direction for non-oriented electrical steel and parallel to the rolling direction for grain-directed steel. It will be carefully cut without any additional deformation. The surface of the sample should be free of cracks or marks, and there should be no excessive burrs on the edges.
