Book excerpt: This Standard specifies the method for determining the ability of metal sheets and strips to withstand plastic deformation during drawing forming by the Erichsen Cupping Test. This Standard is applicable to the determination of metal sheets and strips with a thickness of 0.1mm~2.0mm and a width of no less than 90mm.
