This paper reports that the mechanical behavior of a Nb3Sn cable-in-conduit conductor after the heat treatment is a crucial characteristic to assess the conductor performances in a big coil under the operating loads. On the other hand, the mechanical properties of the conductor and its components before the heat treatment are important to lay out the right tools and machinery of the manufacturing and winding process. Extensive mechanical test on full size and subsize cables, with and without steel jacket, at liquid nitrogen and liquid helium temperature have been carried out on the three prototype CIC conductors manufactured by the industry. The measurements include: tensile tests from the basis strand to the full size conductor, compression tests of cable and jacket, bending test, friction test between cable and jacket transversal and axial cable loading with hysteresis measurements.
