What is BS EN 61788-19 – Superconductivity about?
BS EN 61788-19 is a European standard that discusses the room temperature tensile test of reacted Nb3Sn composite for superconductivity. Superconducting wire can carry immense electrical currents with no heating, which allows it to generate large magnetic fields.
BS EN 61788-19 covers a test method detailing the tensile test procedures to be carried out on reacted Cu/Nb3Sn composite superconducting wires at room temperature. The object of this test is to measure the modulus of elasticity and to determine the proof strength of the composite due to the yielding of the copper and the copper-tin components from the stress versus strain curve.
The sample covered by BS EN 61788-19 test procedure should have a bare round or rectangular cross-section with an area between 0,15 mm2 and 2,0 mm2 and a copper to non-copper volume ratio of 0,2 to 1,5 and should have no insulation.
Who is BS EN 61788-19 – Superconductivity for?
BS EN 61788-19 on the room temperature tensile test of reacted Nb3Sn composite superconductors applies to:
- Civil engineering
- Testing of superconductivity
Why should you use BS EN 61788-19 – Superconductivity?
Superconducting wire can carry immense electrical currents with no heating, which allows it to generate large magnetic fields. An electromagnet with non-superconducting copper windings would melt with the same current.
BS EN 61788-19 provides you with a guide on commercial composite superconductors which have a high current density and a small cross-sectional area. The major application of composite superconductors is to build superconducting magnets. This is done either by winding the superconductor on a spool and applying the heat treatment together with the spool afterwards (wind and react) or by heat treatment of the conductor before winding the magnet (react and wind).
As a user of BS EN 61788-19, you can facilitate a large electromagnetic force applied to the superconducting wires because of their high current density.
