标准摘要
[中文适用范围]： IEC 61788 的这一部分涵盖了一种测试方法，详细说明了在室温下对 Cu/Nb-Ti 超导复合线进行的拉伸测试程序。该测试用于测量弹性模量、由于铜部件屈服而导致的复合材料的 0.2% 屈服强度以及拉伸强度。断裂后伸长率的值和由于 Nb-Ti 部件屈服而产生的第二类 0.2% 屈服强度仅作为参考（参见条款 A.1 和 A.2）。该测试程序覆盖的样品具有圆形或矩形横截面，面积为 0.15 mm2 至 2 mm2，铜与超导体的体积比为 1.0 至 8.0，并且没有绝缘涂层。 [外文原描述]： This part of IEC 61788 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. This second edition cancels and replaces the first edition published in 2000. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the minimum distance between grips was changed from 100 mm to 60 mm; - accuracy and precision statement were converted to uncertainty statements.
