scope:
Covers a test method for the determination of the residual resistance ratio (RRP) of a composite superconductor comprised of Nb-Ti filaments and Cu, Cu-Ni or Cu/Cu/Ni matrix. This method is intended for use with superconductors that have a rectangular or round cross-section. RRR less than 350, and cross-sectional area less than rectangular or round cross-section, RRR less than 350, and cross-sectional area less than 3 mm². All measurement shall be done without an applied magnetic field.
