Scope
This part of GB/T 15825 specifies the test method for the expansion forming performance of metal sheets using the expansion ratio as an indicator, which is suitable for metal sheets and coils with a thickness of 1.2 mm to 6.0 mm. The width of the samples used should generally not be less than 90 mm.
