标准摘要
[中文适用范围]： IEC 61788 的这一部分描述了使用直流或低斜率磁力测定法测量 Cu/Nb-Ti 复丝复合材料中磁滞损耗的注意事项。本国际标准规定了多丝铜/铌钛复合导体磁滞损耗的测量方法。假设测量是在温度等于或接近 4@2 K 的圆线上进行的。直流或低斜率磁力测量将使用超导量子干涉装置（SQUID 磁力计@参见附件 A.）或振动样品进行磁力计（VSM）。如果注意到校准磁力计结果之间的差异@ VSM 结果@ 外推至零斜坡率@ 将被视为确定的。附录 B 给出了一般超导体测量的扩展。 [外文原描述]： IEC 61788-13:2012 describes considerations for the measurement of hysteretic loss in Cu/Nb-Ti multifilamentary composites using DC- or low-ramp-rate magnetometry. This international standard specifies a method of the measurement of hysteretic loss in multifilamentary Cu/Nb-Ti composite conductors. Measurements are assumed to be on round wires with temperatures at or near 4,2 K. DC or low-ramp-rate magnetometry will be performed using either a superconducting quantum interference device or a vibrating-sample magnetometer. Extension to the measurement of superconductors in general is given in Annex. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. Modifications made to the second edition extend to the measurement of superconductors in general, in various sample sizes and shapes, and at temperatures other than 4,2 K, and use the word "uncertainty" for all quantitative statistical expressions to eliminate the quantitative use of "precision" and "accuracy".
