YB/T 4731-2019 The method of repeated bending test for electrical steel strips
Abstract
This standard specifies the principles, terms and definitions, symbols and explanations, principles, test devices, samples, test procedures, test results, and inspection reports for the repeated bending test method of electrical steel strips (sheets). This standard is applicable to the evaluation of the ductility of oriented and non-oriented electrical steel strips (sheets) by the repeated bending test method using Epstein samples, and the samples are in an unannealed state.
