Organization: IEC
Publication Date: 1 January 2016
Status: inactive
Page Count: 70
ICS Code (Superconductivity and conducting materials): 29.050
ICS Code (Measurement of electrical and magnetic quantities): 17.220.20
scope:

This part of IEC 61788 specifies a test method for the determination of the residual resistance ratio (RRR) of Nb-Ti and Nb3Sn composite superconductors with Cu, Cu-Ni, Cu/Cu-Ni and Al matrix. This method is intended for use with superconductor specimens that have a monolithic structure with rectangular or round cross-section, RRR value less than 350, and crosssectional area less than 3 mm2. In the case of Nb3Sn, the specimens have received a reaction heat-treatment.
