本标准规定了Cu/Nb-Ti复合超导线中铜-超[体积]比的测试方法。 本方法和附录A中提供的可选方法适用于截面积为0.1 mm~3 mm、Nb-Ti丝直径为2 μm~200 μm,铜-超[体积]比不小于0.5的Cu/Nb-Ti复合超导线。 本标准的Cu/Nb-Ti复合测试导体具有圆形或矩形截面的单一化结构。本标准采用硝酸溶解铜,给出了常规测试所允许的偏差和其他具体的限定。 截面积、丝直径和铜-超[体积]比超出本范围的Cu/Nb-Ti复合超导线,也可以使用本方法测量,但不确定度将降低。此外,特殊的情况下,对于超出规定范围的导体,测试样品可能存在特殊的几何形状,但为了简化及保持低不确定度,本标准不涉及此类问题。 经过适当的修正,本标准给出的测试方法可以应用于其他复合超导线。
