BS EN 61788-6 is a European standard and a part of the BS EN 61788 series that discusses the room temperature tensile test of Cu/Nb-Ti composite superconductors. Superconducting wire can carry immense electrical currents with no heating, which allows it to generate large magnetic fields.
BS EN 61788-6 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 (see Clauses A.1 and A.2). The sample covered by this test procedure has a round or rectangular cross-section with an area of 0,15 mm2 to 2 mm2 and a copper to superconductor volume ratio of 1,0 to 8,0 and without the insulating coating.
BS EN 61788-6 on composite superconductors applies to:
Superconducting wire can carry immense electrical currents with no heating, which allows it to generate large magnetic fields. Tensile stress is a tensile force divided by the original cross-sectional area at any moment during the test.
BS EN 61788-6 provides you with the test which consists of straining a test piece by tensile force, generally to fracture, to determine the mechanical properties. It provides the major application of the composite superconductors is to build superconducting magnets. While the magnet is being manufactured, complicated stresses are applied to its windings and, while it is being energized, a large electromagnetic force is applied to the superconducting wires because of its high current density.
BS EN 61788-6 helps you in determining the mechanical properties of the superconductive wires, of which the windings are made. BS EN 61788-6 provides you with comprehensive guidance useful throughout the process of mechanical properties measurements.
