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 with 30 rRRR. The test method should be valid for specimens with rectangular or round cross-section, cross-sectional area greater than 1 square millimeter but less than 20 square millimeter, and a length not less than 10 times the width or diameter.
