Superconductivity - Part 26: Critical current measurement - DC critical current of RE-Ba-Cu-O composite superconductors

IEC 61788-26:2020 specifies a test method for determining the DC critical current of short RE (rare earth)-Ba-Cu-O (REBCO) composite superconductor specimens that have a shape of straight flat tape. This document applies to test specimens shorter than 300 mm and having a rectangular cross section with an area of 0,03 mm2 to 7,2 mm2, which corresponds to tapes with width ranging from 1,0 mm to 12,0 mm and thickness from 0,03 mm to 0,6 mm. This method is intended for use with superconductor specimens that have critical current less than 300 A and n-values larger than 5 under standard test conditions: the test specimen is immersed in liquid nitrogen bath at ambient pressure without external magnetic field during the testing. Deviations from this test method that are allowed for routine tests and other specific restrictions are given in this document.

Supraconductivité - Partie 26: Mesurage du courant critique - Courant critique continu des composites supraconducteurs de RE-Ba-Cu-O

L’IEC 61788-26:2020 spécifie une méthode d'essai pour la détermination du courant critique continu des échantillons de composites supraconducteurs RE (terre rare)-Ba-Cu-O (REBCO) courts en forme de ruban plat et rectiligne. Le présent document s'applique aux échantillons d’essai d'une longueur inférieure à 300 mm et d'une superficie de section rectangulaire de 0,03 mm2 à 7,2 mm2, ce qui correspond aux rubans d’une largeur de 1,0 mm à 12,0 mm et d’une épaisseur de 0,03 mm à 0,6 mm. Cette méthode est destinée à être utilisée avec des échantillons de supraconducteurs caractérisés par un courant critique inférieur à 300 A et des valeurs n supérieures à 5 dans les conditions d’essai normalisées: l’échantillon d’essai est immergé dans un bain d’azote liquide à pression ambiante sans champ magnétique externe pendant l’essai. Le présent document spécifie les écarts par rapport à cette méthode d’essai qui sont admis dans les essais individuels de série, ainsi que d'autres restrictions spécifiques.
