This part of IEC 61788-25 specifies a test method detailing the tensile test procedures to be carried out on REBCO superconductive composite tapes at room temperature. This test is used to measure the modulus of elasticity and 0,2 % proof strength. The values for elastic limit, fracture strength and percentage elongation after fracture shall serve only as a reference. The sample covered by this test procedure should have a rectangular cross-section with an area of 0,12 mm2 to 6,0 mm2 (corresponding to the tapes with width of 2,0 mm to 12,0 mm and thickness of 0,06 mm to 0,5 mm). Additional information on scope is described in Annex A.1.
