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.
