This part of IEC 61788 describes measurements of the intrinsic surface impedance (ZS) of HTS films at microwave frequencies by a modified two-resonance mode dielectric resonator method [13, 14]2. The object of measurement is to obtain the temperature dependence of the intrinsic ZS at the resonant frequency f0.The frequency and thickness range and the measurement resolution for the intrinsic ZS of HTS films are as follows:. frequency: up to 40 GHz;. film thickness: greater than 50 nm;. measurement resolution: 0,01 mÙ at 10 GHz.The intrinsic ZS data at the measured frequency, and that scaled to 10 GHz, assuming the f2 rule for the intrinsic surface resistance

This part of IEC 61788 covers a test method for the determination of the residual resistance ratio (RRR) of composite superconductors 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 monolithic structure with rectangular or round cross-section, RRR less than 350, and cross-sectional area less than 3 mm2. All measurements are 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 Clause A.3.

This part of IEC 61788 covers a test method for the determination of the residual resistance ratio (RRR) of Nb3Sn composite superconductors. This method is intended for use with superconductor specimens that have a monolithic structure with rectangular or round crosssection, RRR less than 350 and cross-sectional area less than 3 mm2, and have received a reaction heat-treatment. Ideally, it is intended that the specimens be as straight as possible; however, this is not always the case, thus care must be taken to measure the specimen in its as received condition. All measurements are done without an applied magnetic field.The method described in the body of t
