ActiveResidual resistance ratio measurement—Residual resistance ratio of Nb-Ti and Nb3Sn composite superconductors
剩余电阻比测量 铌-钛（Nb-Ti）和铌三锡（Nb3Sn）复合超导体剩余电阻比测量
Application Summary AI generated
This standard specifies the measurement method for the residual resistance ratio (RRR) of Nb-Ti and Nb3Sn composite superconductors, which is a key quality indicator for superconducting wires and tapes. It is applied in the manufacturing and testing of superconducting materials used in high-field magnets, such as those in magnetic resonance imaging (MRI) systems, particle accelerators, and fusion reactors. The standard ensures consistent evaluation of conductor purity and performance under cryogenic conditions, guiding procurement and quality control for superconducting applications.
