The cupping test is a test method applied in the metalworking industry and is used to determine the ductility of sheet metals and strips.
For the performance of cupping tests on sheet metal a spherical drawing punch is pressed into a clamped metal sheet until a crack appears. The cupping test is used to assess drawing formability.
Cupping tests are described in various standards. Here you will find an overview of the current standards and tests.
