标准摘要
[中文适用范围]: IEC 61788的本部分涵盖了测定Cu/Nb-Ti复合超导线材中铜与超导体体积比的测试方法。该测试方法适用于横截面积为 0.1 mm 至 3 mm、Nb-Ti 细丝直径为 2 μm 至 200 μm 的 Cu/Nb-Ti 复合超导线材,并且铜与超导体的体积比为0.5或更大。该方法中讨论的 Cu/Nb-Ti 复合材料测试导体具有圆形或矩形横截面的整体结构。该测试方法是通过用硝酸溶解铜来进行的。本标准给出了例行试验所允许的与本试验方法的偏差以及其他具体限制。超出横截面积、细丝直径和铜与超导体体积比限制的 Cu/Nb-Ti 导体可以用本方法测量,但精度预计会降低。其他更专业的样本测试几何形状可能更适合超出限制的导体,并且为了简化和保持精度,已从本标准中省略。本标准给出的测试方法经过适当修改后预计适用于其他超导复合线材。 [外文原描述]: Covers a test method for the determination of copper to superconductor volume ratio of Cu/Nb-Ti composite superconducting wire. The Cu/Nb-Ti composite test conductor discussed in this method has a monolithic structure with a round or rectangular cross-section. This test method is carried out by dissolving the copper with nitric acid. Deviations from this test method that are allowed for routine tests and other specific restrictions are given in this standard.
