Superconductivity - Part 23: Residual resistance ratio measurement - Residual resistance ratio of cavity-grade Nb superconductors

This part of IEC 61788 addresses a test method for the determination of the residual resistance ratio (RRR), rRRR, of cavity-grade niobium. This method is intended for high-purity niobium grades with 150 < rRRR < 600. The test method is valid for specimens with rectangular or round cross-section, cross-sectional area greater than 1 mm2 but less than 20 mm2, and a length not less than 10 nor more than 25 times the width or diameter.

IEC 61788-23:2021 est disponible sous forme de IEC 61788-23:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L’IEC 61788-23:2021 spécifie une méthode d'essai pour la détermination du rapport de résistance résiduelle (RRR), rRRR, du niobium à cavités. Cette méthode est destinée aux nuances de niobium de grande pureté de 150 < rRRR < 600. La méthode d’essai est valide pour des éprouvettes à sections rectangulaires ou circulaires, de surface de section supérieure à 1 mm2 mais inférieure à 20 mm2, et dont la longueur n’est pas inférieure à 10 fois ni supérieure à 25 fois la largeur ou le diamètre.
