ISO 9649:2016规定了一种方法,用于测定直径尺寸为0.3 mm至10.0 mm(包括0.3 mm至10.0 mm)的金属丝在反向扭转期间承受塑性变形的能力。该测试用于检测表面缺陷,以及评估延展性。
ISO 9649:2016 specifies a method for determining the ability of metallic wire of diameter dimension from 0,3 mm to 10,0 mm inclusive to undergo plastic deformation during reverse torsion. This test is used to detect surface defects, as well as to assess ductility.
