Part 25: Mechanical properties measurement – Room temperature tensile test on REBCO wires

(IEC 61788-25:2018); German version EN IEC 61788-25:2018
Class/Status: Standard, valid

VDE Art. No.: 0300119

This part of IEC 61788 specifies the test method and procedures for testing tensile mechanical properties of 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 serve only as a reference. This document applies to samples having a rectangular cross-section with an area of 0,12 mm<(hoch)2> to 6,0 mm<(hoch)2> (corresponding to the tapes with width of 2,0 mm to 12,0 mm and thickness of 0,06 mm to 0,5 mm).
