BS EN IEC 61788-24:2018

This standard BS EN IEC 61788-24:2018 Superconductivity is classified in these ICS categories:

• 77.040.10 Mechanical testing of metals
• 29.050 Superconductivity and conducting materials
• 17.220 Electricity. Magnetism. Electrical and magnetic measurements

IEC 61788-24:2018 describes a test method for determining the retained critical current after double bending at room temperature of short and straight Ag- and/or Ag alloy-sheathed Bi-2223 superconducting wires that have the shape of a flat or square tape containing mono- or multicores of oxides. The wires can be laminated with copper alloy, stainless steel or Ni alloy tapes.
The test method is intended for use with superconductors that have a critical current less than 300 A and an n-value larger than 5.
