Procedures
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.

BIFMA X5.1 2011 Base Test Procedure:

Remove the casters or glide foot (castors/ glide stems shall remain in place). Caster/ glide stems are required for support. Remove the seat support mechanism and height adjustment mechanism (if applicable) from the base. Apply the load to the vertical support column, or test fixture that simulated the taper/base interface. 

a) A force of 11,120 N (2500 lbf.) shall be applied for one minute

b) Remove the force

c) Apply a second force of 11,120 N (2500 lbf.) for one minute

d) Remove the load
