Annotation of standard text IEC 61788-23-ed.3.0 :

IEC 61788-23:2024 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. LIEC 61788-23:2024 specifie une methode dessai pour la determination du rapport de resistance residuelle (RRR), rRRR, du niobium a cavites. Cette methode est destinee aux nuances de niobium de grande purete de 150 < rRRR < 600. La methode dessai est valide pour des eprouvettes a sections rectangulaires ou circulaires, de surface de section superieure a 1 mm2, mais inferieure a 20 mm2, et dont la longueur nest pas inferieure a 10 fois ni superieure a 25 fois la largeur ou le diametre.
