规定了测定大块高温超导体俘获场（俘获磁通密度）的试验方法。 本国际标准适用于具有明确形状的大颗粒块状氧化物超导体，如圆片、矩形和六角形颗粒。可在4.2 K至90 K的温度下评估截留通量密度。为了标准化，将针对液氮温度报告截留通量密度。

Specifies a test method for the determination of the trapped field (trapped flux density) of bulk high temperature superconductors. This International Standard is applicable to large grain bulk oxide superconductors that have well defined shapes such as round discs, rectangular, and hexagonal pellets. The trapped flux density can be assessed at temperatures from 4,2 K to 90 K. For the purpose of standardization, the trapped flux density will be reported for liquid nitrogen temperature.
