28.2.5 Operation of an interlock in normal use shall not inconvenience the operator so as to encourage
deliberate defeat of the interlock.
28.2.6 Unless known to be acceptable for 100,000 cycles of operation, an interlock shall withstand
100,000 cycles of operation controlling a load no less severe than it controls in the appliance, and shall
function normally upon completion of the test.
28.2.7 If an automatically reset protective device is employed in an appliance, automatic restarting of the
motor shall not result in a risk of injury.
28.2.8 The requirement in 28.2.7 necessitates the use of an interlock if moving parts or the like may
cause a risk of injury to persons upon automatic restarting of the motor.

29 Temperatures

29.1 During the temperature test, the temperatures of a surface that may be contacted by the user shall
not be more than the value specified in Table 29.1. If the test is conducted at a room temperature of other
than 25°C (77°F), the results are to be corrected to that temperature.
A handle or knob that is grasped for lifting or holding
A handle or a knob that is contacted, but does not involve lifting or
holding; and other surfaces subject to contact in operation and user
maintenance
a A handle, a knob, or the like, made of a material other than metal that is plated or clad with metal having a thickness of 0.005
inches (0.13 mm) or less is considered to be a nonmetallic part.

30 Stability

30.1 When tipped through an angle of 10 degrees as described in 30.2, an appliance shall not overturn
and shall return to its normal at-rest position.
Exception: An undercounter appliance.
30.2 The test required by 30.1 is to be conducted with the appliance set up for normal operation both with
and without any removable waste collecting containers in place, and with a load of 15 pounds per cubic
3
foot (240.3 kg/m ) or unloaded, whichever creates the more unstable situation. Leveling screws are to be
adjusted to raise the appliance as high as possible or 1 inch (25.4 mm) above floor level, whichever is
less. Casters or wheels are to be arranged in the position that results in the least stability, and the
appliance is to be tipped 10 degrees in the direction most likely to overturn it. Legs or other means of
support may be blocked to prevent the appliance from sliding during the test.
