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.
