通过对钢索的产品技术要求、钢索组成结构、试样夹持方式、试验参数等方面进行分析，提出了一种钢索钢丝绳断后伸长率测试的新方法。试验结果表明：采用新试验工艺、专用工装及大量程引伸计进行断后伸长率测试，不仅能够锁紧试样，而且又不损伤试样，拉伸过程符合GB/T 228.1—2010的要求。该方法填补了实验室的检测空白，获得了可靠的试验数据，满足了产品使用部门的测试需求。

Based on the analysis of the technical requirements and composition structure of the steel wire rope, the clamping method of the sample and the test parameters, a new method for testing elongation after fracture of steel wire rope was proposed. The test results show that the new test process, special tooling and a large range extensometer were used to test the elongation after fracture, which not only could lock the sample, but also did not damage the sample. The tensile process met the standard requirements of GB/T 228.1-2010. The method filled the testing gap in the laboratory, obtained reliable test data, and met the test requirements of the product use department.
