The following document 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 15 < RRRr< 600. The test method should be 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.
