A chair with casters is mounted on the moveable platform as shown in Figure 13. A 300-pound load is applied to the chair seat with the chair spindle fully extended. The base is attached to a mechanical device that exerts a horizontal push and pull of from 30 inches to 34 inches as illustrated in the figure. The base and casters are free to rotate and swivel. The machine operates continuously at a rate of 8 to 10 cycles per minute with a maximum speed of 50 feet per minute. One cycle consists of a forward and backward stroke of the mechanical device. Testing continues until the base or a caster suffers structural breakage, loss of serviceability, or a failure that would in any way cause personal injury to the occupant or bystanders, or, the desired acceptance level is met.
