标准摘要
[中文适用范围]： IEC 61788的本部分规定了测定Cu、Cu-Ni、Cu/Cu-Ni和Al基体的Nb-Ti和Nb3Sn复合超导体的残余电阻比(RRR)的试验方法。该方法适用于具有矩形或圆形横截面、RRR 值小于 350、横截面积小于 3 mm2 的整体结构的超导体样品。对于 Nb3Sn，样品已接受反应热处理。 [外文原描述]： IEC 61788-4:2016 specifies a test method for the determination of the residual resistance ratio (RRR) of Nb-Ti and Nb3Sn composite superconductors with Cu, Cu-Ni, Cu/Cu-Ni and Al matrix. This method is intended for use with superconductor specimens that have a monolithic structure with rectangular or round cross-section, RRR value less than 350, and cross-sectional area less than 3 mm2. In the case of Nb3Sn, the specimens have received a reaction heat-treatment. This fourth edition cancels and replaces the third edition published in 2011. This edition constitutes a technical revision.
