Safety chain attachment points are the means by which the safety chains are attached to the drawbar. These points must be located as near as practicable to the tow coupling. Where two points of attachment are required, they must be mounted one on either side of the centreline of the drawbar.
Each safety chain attachment point must be capable of withstanding the following minimum forces without incurring either any residual deformation that would interfere or degrade the function of the assembly, or any breaks, cracks or separation of components:
Longitudinal tension and compression (N) 1.5 x 9.81 x ATM (in kg)
Vertical tension and compression (N) 0.5 x 9.81 x ATM (in kg).
