IEC 61788-7:2020 describes measurement of the surface resistance (Rs) of superconductors at microwave frequencies by the standard two-resonator method. The object of measurement is the temperature dependence of Rs at the resonant frequency. The applicable measurement range of Rs for this method is as follows:
\n– Frequency: 8 GHz < f < 30 GHz
\n– Measurement resolution: 0,01 m ? at 10 GHz
\nThe Rs data at the measured frequency, and that scaled to 10 GHz, assuming the f 2 rule for comparison, is reported. This third edition cancels and replaces the second edition, published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
\na) informative Annex B, relative combined standard uncertainty for surface resistance measurement has been added;
\nb) precision and accuracy statements have been converted to uncertainty;
\nc) reproducibility in surface resistant measurement has been added.<\/p>\n","protected":false},"excerpt":{"rendered":"
