Superconductivity - Part 26: Critical current measurement - DC critical current of RE-Ba-Cu-O composite superconductors
Also Known As:
The standard specifies a method for determining the DC critical current of RE-Ba-Cu-O composite superconductors. It focuses especially on testing brief specimens in the form of straight, flat tapes. The test specimens must be shorter than 300 mm and have a rectangular cross-section with an area ranging from 0.03 mmsup>2/sup>to 7.2 mmsup>2/sup>, according to the standard. This equates to tapes ranging in width from 1.0 mm to 12.0 mm and in thickness from 0.03 mm to 0.6 mm.
Under standard test conditions, the procedure described in the standard is intended for use with superconductor specimens with critical currents less than 300 A and n-values greater than 5. During testing, the test specimen is immersed in a liquid nitrogen bath at ambient pressure without the presence of an external magnetic field. For routine tests, the document also allows for specified deviations from the normal test technique and describes any other unique limits that must be considered.
