EN IEC 61788-7:2020

Superconductivity - Part 7: Electronic characteristic measurements - Surface resistance of high-temperature superconductors at microwave frequencies

IEC 61788-7:2020 is available as IEC 61788-7:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.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: - Frequency: 8 GHz < f < 30 GHz - Measurement resolution: 0,01 m Ω at 10 GHz The 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: a) informative Annex B, relative combined standard uncertainty for surface resistance measurement has been added; b) precision and accuracy statements have been converted to uncertainty; c) reproducibility in surface resistant measurement has been added.

Supraconductivité - Partie 7: Mesurages des caractéristiques électronique - Résistance de surface des supraconducteurs haute température critique aux hyperfréquences

IEC 61788-7:2020 est disponible sous forme de IEC 61788-7:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.IEC 61788-7:2020 décrit le mesurage de la résistance de surface (Rs) des supraconducteurs aux hyperfréquences par la méthode normalisée à deux résonateurs. L'objet du mesurage est la dépendance de la résistance de surface Rs vis-à-vis de la température à la fréquence de résonance. La plage de mesures applicable des résistances de surface Rs pour cette méthode est la suivante: - Fréquence: 8 GHz < f < 30 GHz - Résolution de mesure: 0,01 m Ω à 10 GHz Les données de Rs à la fréquence mesurée, et celles mises à l'échelle à 10 GHz, en prenant pour hypothèse la règle de comparaison f 2, doivent être consignées. Cette troisième édition annule et remplace la deuxième édition parue en 2006. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) l’ajout de l’Annexe B informative, incertitude type composée relative pour le mesurage de la résistance de surface; b) les déclarations de fidélité et d'exactitude ont été converties en incertitude; c) l'ajout de la reproductibilité du mesurage de résistance de surface.
