GB/T 31979-2015 in English

This standard provides a method for determining the rotational performance of steel wire ropes. It outlines the procedures, equipment, and conditions necessary to accurately assess how steel wire ropes behave under rotational stress. The method ensures consistency in testing practices, enabling reliable comparisons between different products. It specifies the parameters that must be controlled during testing, such as temperature, humidity, and the speed of rotation. The standard also details the calculation methods used to evaluate the results of the tests. By following this standard, testing laboratories can ensure that their measurements are accurate and repeatable. The document is structured to guide users through each step of the testing process, from sample preparation to final data analysis.
