标准范围

指定用于确定直径或厚度为0.3至10 mm（含0.3至10 mm）的金属丝在反向弯曲期间承受塑性变形的能力的方法。ISO 7801适用的直径和厚度范围可在相关产品标准中更精确地规定。该试验包括在一端固定的试样在相反方向上重复弯曲90度，每次弯曲都在规定半径的圆柱形支架上。

Specifies the method for determining the ability of wire of diameter or thickness 0,3 to 10 mm inclusive to undergo plastic deformation during reverse bending. The range of diameters of thicknesses for which ISO 7801 is applicable may be more exactly specified in the relevant product standard. The test consists of repeated bending, through 90 in opposite directions, of a test piece held at one end, each bend being over a cylindrical support of a specified radius.
