Establishes test conditions and strength requirements to be met by 40 mm and 50 mm drawbar couplings, and the corresponding drawbar eyes. Gives the equation to be used to calculate the F-value (expressed in kN), shows the application of horizontal test load (figure 1), and describes the loading cycle and the selected frequency as well as strength criteria.
