标准摘要
[中文适用范围]： 规定了测定板材和带材在反向弯曲中承受塑性变形能力的方法。 仅在事先达成协议后才可应用于铝及其合金。 反向弯曲测试包括将一端固定的矩形测试件沿相反方向重复弯曲 90 度，每次弯曲都在指定半径的圆柱形支撑件上。 [外文原描述]： 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.
