BS EN 61788-11:2011
This standard BS EN 61788-11:2011 Superconductivity is classified in these ICS categories:
- 17.220.20 Measurement of electrical and magnetic quantities
- 29.050 Superconductivity and conducting materials
This part of IEC 61788 covers a test method for the determination of the residual resistance ratio (RRR) of Nb3Sn composite superconductors. This method is intended for use with superconductor specimens that have a monolithic structure with rectangular or round cross-section, RRR less than 350 and cross-sectional area less than 3 mm2, and have received a reaction heat-treatment. Ideally, it is intended that the specimens be as straight as possible; however, this is not always the case, thus care must be taken to measure the specimen in its as received condition. All measurements are done without an applied magnetic field.
The method described in the body of this standard is the “reference” method and optional acquisition methods are outlined in Clause A.3.
