AbolishedMetallic materials - Wire - Part 2: Reverse torsion test
金属材料 线材 第2部分：双向扭转试验方法
Application Summary AI generated
This standard specifies the method for conducting a reverse torsion test on metallic wire, where the wire is twisted alternately in opposite directions until fracture or a specified number of reversals. It is applied in the quality control and mechanical testing of wires used in industries such as construction, automotive, and aerospace, particularly for assessing ductility and resistance to torsional fatigue. The test is relevant for manufacturers and laboratories evaluating wire products like springs, cables, and fasteners.
