IEC 61788-26 specifies a test method for determining the DC critical current of shortRE (rare earth)-Ba-Cu-O (REBCO) composite superconductor specimens that have a shape ofstraight flat tape. This document applies to test specimens shorter than 300 mm and having arectangular cross section with an area of 0,03 mm2 to 7,2 mm2, which corresponds to tapeswith 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 lessthan 300 A and n-values larger than 5 under standard test conditions: the test specimen isimmersed in liquid nitrogen bath at ambient pressure without external magnetic field during thetesting. Deviations from this test method that are allowed for routine tests and other specificrestrictions are given in this document.
