IEC 61788-24:20 18描述了一种用于确定具有包含单核或多核氧化物的扁平或方形带形状的短且直的银和/或银合金护套的Bi-2223超导线材在室温下双重弯曲后的保留临界电流的测试方法。导线可以用铜合金、不锈钢或镍合金带层压。 该测试方法旨在用于临界电流小于300 A且n值大于5的超导体。

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.
