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。该测试用于测量由于铜成分的屈服而导致的复合材料的弹性模量@ 0@2% 屈服强度@和拉伸强度。断裂后伸长率值和 Nb-Ti 部件屈服引起的第二类 0@2% 屈服强度值仅作为参考(见 A.1 和 A.2)。该测试程序所覆盖的样品具有圆形或矩形横截面,面积为0@15mm2至2mm2,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]: IEC 61788-6:2011 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. 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 third edition cancels and replaces the second edition published in 2008. It constitutes a technical revision which adds a new Annex C including specific examples of uncertainty estimation related to mechanical tests.
