What is PD IEC/TR 63114- Reverse bend test method for electrical steel about?
PD IEC/TR 63114 is an International Standard on magnetic alloys and steels which are typically used in electronics, for example, transformers and magnetic shielding.
PD IEC/TR 63114 for evaluating the ductility of electrical steel strips and sheets.
This test method is applicable to Epstein test strip specimens obtained from non-oriented and grain-oriented electrical steel of any grade. The test specimens shall not be annealed.
Who is PD IEC/TR 63114 - Reverse bend test method for electrical steel for?
PD IEC/TR 63114 on electrical steel is relevant to:
- Steel industry
- Magnet manufacturers
- Electrical engineers
- Electrical industry
Why should you use PD IEC/TR 63114- Reverse bend test method for electrical steel?
The reverse bend test is widely used in industry for the evaluation of ductility of electrical steel. This test includes the repeated bending of a rectangular test specimen clamped on one end through 90° in opposite directions over a pair of mandrels having a cylindrical cambered surface of 5 mm in radius, until failure.
PD IEC/TR 63114 describes the general principle and technical details of the reverse bend test especially for the evaluation of the ductility of electrical steel with respect to the two modes, Mode A according to ISO 7799 and Mode B according to ASTM A720 and JIS C2550.
PD IEC/TR 63114 provides information on a specially designed apparatus for the reverse bend test, which can be used for both modes, and also gives test results on the dependence of the number of bends on the tensile force applied to the specimen.
By conducting the reverse bend test in compliance with PD IEC/TR 63114, you can demonstrate the ductility and soundness of the electrical steel strip and sheet. This can ultimately avoid risks of product failure.
