Abstract
1 Scope
This part of [IEC 61788](/search?q=IEC%C2%A061788)
addresses a test method for the determination of the residual resistance ratio ( RRR ), r RRR , of cavity-grade niobium. This method is intended for high-purity niobium grades
with 150 < r RRR < 600. The test method is 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.
