IEC 61788-23:2018 addresses a test method for the determination of the residual resistance ratio (RRR) of cavity-grade niobium. The test method should be valid for specimens with rectangular or round cross-section, cross-sectional area greater than 1 mm 2 but less than 20 mm 2, and a length not less than 10 nor more than 25 times the width or diameter.
