Metallic materials -- Sheet and strip 3 mm thick or less -- Reverse bend test
This standard was last reviewed and confirmed in 2018. Therefore this version remains current.
Specifies the method for determining the ability of sheet and strip to undergo plastic deformation in reverse bending. Can be applied to aluminium and its alloys only after previous agreement. The reverse bend test consists of repeated bending through 90 , in opposite directions, of a rectangular test piece held at one end, each bend being over a cylindrical support of specified radius.
