标准摘要
[中文适用范围]： 本部分 IEC 61788 规定了用于测定腔体级铌的残余电阻比（RRR，rRRR）的测试方法。本方法适用于150 < rRRR < 600的高纯度铌材料。测试方法适用于横截面为矩形或圆形、横截面积大于1 mm²但小于20 mm²、长度不小于宽度或直径的10倍且不大于25倍的样品。 [外文原描述]： IEC 61788-23:2024 addresses a test method for the determination of the residual resistance ratio (RRR), rRRR, of cavity-grade niobium. This method is intended for high-purity niobium grades with 150 < rRRR < 600. The test method is valid for specimens with rectangular or round cross-section, cross-sectional area greater than 1 mm2 but less than 20 mm2, and a length not less than 10 nor more than 25 times the width or diameter.
