Note: Wherever practical, for convenience, the term appliance has been used in lieu of clothes dryer or machine.

1.2

This Standard applies to both cord-connected and permanently connected appliances. The appliances covered by this Standard are intended for use by the general public not specifically trained in the use of the appliance, regardless of the mode by which its operation is initiated. They are for use in households and for commercial purposes, including appliances provided with coin-, ticket-, or card-operated mechanisms, laundry centers and combination washer-dryers.

1.3

This Standard applies to tumbling clothes dryers and non-tumbling clothes dryers, such as drying cabinets, as well as both vented clothes dryers and non-vented clothes dryers, such as condensation-type and heat pump clothes dryers. Additional requirements for heat pump clothes dryers are given in Supplement SD.

1.4

This Standard does not apply to industrial and institutional type appliances. Industrial or institutional appliances are covered under the scope of Electric Commercial Clothes-Drying Equipment, UL 1240.

Note: Industrial and institutional type appliances are not intended for use by the general public, but only by trained or supervised personnel.
