Scope

This document specifies the method for conducting fatigue tests on drive roller chains and plate chains under axial loading. The tests are conducted at room temperature, with alternating tensile loads applied along the length of the chain. This document also stipulates the method for statistical analysis of the test results and the format of the fatigue test results and analysis reports.
