The Facility for Antiproton and Ion Research (FAIR), currently being built in Darmstadt (Germany), needs 21 standard superferric dipoles for its Superconducting FRagment Separator (Super-FRS). The dipoles manufacturing contract has been awarded to Elytt (Spain) in Spring 2017 and CEA Paris-Saclay (Commissariat à l’Energie Atomique) is overseeing the design and manufacturing activities in the context of the in-kind contribution of France to the FAIR project. The design activities are completed and the manufacturing of the First-of-Series (FoS) will be launched by Elytt after it has completed all the mock-up activities which will validate each key manufacturing process. These superferric dipoles have cold NbTi trapezoidal coils (4.5 K) and warm iron (300 K), and several small scale to full-scale mock-ups were developed and tested by Elytt. We develop in this paper, the mechanical tests performed on samples of conductor and impregnated stack of conductors, the results of the winding tests, the tests of the splices required to put the two coils in series and the tests carried out on the full-scale Helium vessel mock-up made of stainless steel.
