Abstract
Residual resistance ratio ( RRR ) of Cu/Nb-Ti Superconductor wire was evaluated by fixed point method. Our measured value of RRR showed good consistency with the average value obtained from round robin test conducted by IEC/TC 90. Our test results showed that the coefficient of variation ( COV ) was kept within 2 %
