Specifies a method of measuring the turning radius, turning diameter, machine clearance diameter, and inside and outside tyre clearance diameters for a wheeled earth-moving machine with its equipment, turning in the horizontal plane. Applies to all types of steerable wheeled earth-moving machinery, irrespective of the type of steering.

This International Standard specifies the methods of measuring the turning radius, turning diameter, machine clearance diameter, and inside and outside tyre clearance diameters, described in the horizontal plane by a wheeled earth-moving machine with its equipment when executing a turn.Field of applicationThis International Standard applies to all types of steerable wheeled earth-moving machinery. It applies irrespective of the type of steering used.
