标准摘要
[中文适用范围]： 本标准描述了运用直流或低扫场速率磁强计方法对Cu／Nb-Ti多丝复合线磁滞损耗进行测量的相 关事宜。本标准所针对的是Cu／Nb-Ti多丝复合导体中磁滞损耗的测量。测量应在4．2 K或4．2 K附 近的温度下针对圆形线进行。直流或低扫场速率磁强计法使用的是超导量子干涉器件(SQUID)磁强 计或振动样品磁强计(VSM)。如果测量中发现用不同的(但均校准过的)磁强计所得的结果存在差异， 则以VSM在外推至零扫场速率下测量的结果为准。 [外文原描述]： Describes considerations for the measurement of hysteretic loss in Cu/Nb-Ti multifilamentary composites using DC- or low-ramp-rate magnetometry. Focuses on 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 (SQUID magnetometer) or a vibrating-sample magnetometer (VSM). In case differences between the calibrated magnetometer results are noted, the VSM results, extrapolated to zero ramp rate, will be taken as definitive.
