《GB/T 18502-2001银或银合金包套铋系氧化物超导体直流临界电流的测定》由TC265（全国超导标准化技术委员会）归口，主管部门为中国科学院。
本标准规定了银或银合金包套铋系氧化物超导体短样品在零外场和液氮温度（77K）附近进行直流临界电流的测定。被测样品应为简单带材或圆线，而非编织带或缆线。所含超导材料既可以是Bi-2223也可以为Bi-2212，其在样品截面上的分布既可是单芯的结构，也可为多芯的结构。本标准适用于临界电流小于200A，n值大于10的超导短样品临界电流的测定。

Scope

This standard specifies the determination of the DC critical current of short samples of silver or silver alloy sheathed bismuth oxide superconductors near zero external field and liquid nitrogen temperature (77K). The sample to be tested shall be simple tape or round wire, not braid or cable. The contained superconducting material can be either Bi-2223 or Bi-2212, and its distribution on the cross-section of the sample can be either a single-core structure or a multi-core structure. This standard applies to the determination of the critical current of superconducting short samples with a critical current less than 200A and an n value greater than 10.
