ISO 20482 Metallic materials – Sheet Erichsen cupping test machine
Metallic materials — Sheet and strip — Erichsen cupping test Machine
Scope
This International Standard specifies a standard test method for determining the ability of metallic
sheets and strips having a thickness from 0,1 mm up to 2 mm and a width of 90 mm or greater to
undergo plastic deformation in stretch forming.
For materials that are thicker and when only narrower strips are available, tools of specified dimensions
are provided.
Through crack
crack that goes through the full thickness of the test piece and is just sufficiently wide to allow light to pass through part of its length

ISO 20482 Sheet Metal Erichsen Cupping Testing Machines
Sheet Metal Erichsen Cupping Testing Machine/tester ISO 20482
GBW-60B Computer Control Erichsen Cupping Testing Machine
1. Application & Features:
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.
2. Standards:
ISO20482: 2003 Metallic materials-Sheet and strip-Erichsen Cupping Test, GB/T4156-2007 Metallic materials-Sheet and strip-Erichsen Cupping Test
