Scope

This part of IEC 61788 covers a test method for the determination of the residual resistance ratio (RRR) 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 3 mm. All measurements shall be done without an applied magnetic field. The method described in the body of this standard is the "reference" method and optional acquisition methods are outlined in annex A.
