ISO 20482 Metallic materials – Sheet Erichsen cupping test machine/tester
The cupping testing machine is used to test extend and stretch capacity of metal thin plate and band. It is the only instrument to test the metal’s plastic deformation. Also it can be used to test non-ferrous metal’s anisotropic character if adding impact cup mould. The machine adopts high precision raster measure instrument to test Erichsen value so it has a high testing precision. It adopts the electric control machinery onload and LCD spoke sensor so it raised the testing precision of the main test force and accuracy of controlling sample breaking.
Cupping Test to Erichsen (ISO 20482) and Olsen (ASTM E643)
The ISO 20482 standard describes the cupping test to Erichsen and is used to determine the ductility of metal sheets and strips. The test is also standardized in ASTM E643 as cupping test to Olsen. An additional description can be found in the Japanese standard JIS Z-224.
The forming process used for this test essentially records the stretching capacity of the metal material, directly comparable with a stretch-forming and bulge removal process. The edge zones (borders) are held, and therefore are not affected, or only slightly affected, by forming. The specimen is pulled until a crack occurs that runs the full thickness of the specimen, and is just wide enough to allow light to pass through part of its length.
