Annotation of standard text IEC 61788-19-ed.1.0 :
IEC 61788-19:2013 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 yielding of the copper and the copper tin components from the stress versus strain curve. Furthermore, the elastic limit, the tensile strength, and the elongation after fracture can be determined by means of the present method, but they are treated as optional quantities because the measured quantities of the elastic limit and the elongation after fracture have been reported to be subject to significant uncertainties according to the international round robin test. The sample covered by this 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. Key words: supraconductivity, mechanical properties La IEC 61788-19:2013 specifie une methode dessai detaillant les modes operatoires dessai de traction a executer a temperature ambiante sur des fils composites supraconducteurs de Cu/Nb3Sn mis en reaction. Lobjectif de cet essai est de mesurer le module delasticite et de determiner la charge depreuve du composite due a la deformation du cuivre et des composants en cuivre et en etain sur la courbe de contrainte en fonction de la deformation. De plus, la limite elastique, la resistance a la traction et lallongement apres fracture peuvent etre determines par le biais de la presente methode, mais ils sont traites comme des grandeurs facultatives, car lessai interlaboratoire international a demontre de considerables incertitudes au sujet des valeurs mesurees pour la limite elastique et pour lallongement apres fracture. Il convient que lechantillon couvert par la presente procedure dessai ait une section transversale circulaire ou rectangulaire avec une surface comprise entre 0,15 mm2 et 2,0 mm2 et un rapport volumique entre le cuivre et le non-cuivre de 0,2 a 1,5. Il convient egalement quil nait pas disolation. Mots cle: supraconductivite, proprietes mecaniques
