Resumen:
IEC 61788-6:2011 covers a test method detailing the tensile test procedures to be carried out on Cu/Nb-Ti superconductive composite wires at room temperature. This test is used to measure modulus of elasticity, 0,2 % proof strength of the composite due to yielding of the copper component, and tensile strength. The value for percentage elongation after fracture and the second type of 0,2 % proof strength due to yielding of the Nb-Ti component serves only as a reference. The sample covered by this test procedure has a round or rectangular cross-section with an area of 0,15 mm 2 to 2 mm 2 and a copper to superconductor volume ratio of 1,0 to 8,0 and without the insulating coating. This third edition cancels and replaces the second edition published in 2008. It constitutes a technical revision which adds a new Annex C including specific examples of uncertainty estimation related to mechanical tests.
