Scope

What is BS EN IEC 61788-4 about?    BS EN IEC 61788-4 is the fourth part of a multi-series that 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 a matrix in a strain-free condition and zero external magnetic fields.   The methods described in BS EN IEC 61788-4 are intended for use with superconductor specimens that have a monolithic structure with rectangular or round cross-section, RRR values less than 350, and cross-sectional area less than 3 mm2. In the case of Nb3Sn, the specimens have received a reaction heat treatment.   Who is BS EN IEC 61788-4 for?    BS EN IEC 61788-4 on superconductivity is relevant to:   Electronics industry BS EN IEC 61788-4:2020 history
