Scope
This part of IEC 61788 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 (SQUID magnetometer@ See Annex A.) 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. Extension to the measurement of superconductors in general is given in Annex B.
