This paper presents a commentary on the test method for the residual resistance ratio (RRR), which is one of the most significant properties for superconductor application, of Cu/Nb-Ti composite superconductors. International standardization of the RRR has been carried forward by IEC-TC90 and now the third working draft (WD) has been prepared. The WD shows scope, definition, apparatus, data acquisition and correction of bending strain. It will be issued as IEC standard 1788-4-1 in the near future.
