GB/T 12968-1991
ActiveEddy current decay method formeasurement of resistivity and residual resistance ratio of pure metals
纯金属电阻率与剩余电阻比涡流衰减测量方法
Application Summary AI generated
This standard specifies the eddy current decay method for measuring the electrical resistivity and residual resistance ratio (RRR) of pure metals. It is applied in metallurgy and materials science for quality control and characterization of high-purity metals, particularly in the production of superconducting materials and electrical conductors. The method is used in laboratory testing to evaluate material purity and low-temperature electrical performance.
