These refrigerators are intended for use both indoors in adequately ventilated structures and outdoors.

This standard applies to refrigerators designed for self-contained fuel supplies and using fuel cylinders of not more than 75 cubic inches (1230 cm3) (21/2 pounds nominal water capacity). Fuel supplies shall be in accordance with the Standard for the Storage and Handling of Liquefied Petroleum Gases, ANSI/NFPA No.58.

Refrigerant systems shall comply with the applicable provisions of the Standard Safety Code for Mechanical Refrigeration, ANSI/ASHRAE 15.

A refrigerator submitted for examination under this standard shall be provided with a direct self-contained type of system employing the absorption or adsorption principle of refrigeration.

This standard also covers all electrical equipment, wiring and accessories built in or supplied with refrigerators for use with low voltage direct current or alternating current. Appliances for use with alternating current shall be nominally rated 120 volts, 60 hertz.

Refrigerators for use with gas fuel that are also for use with electricity shall also comply with the applicable provisions of the Standard for Household Refrigerators and Freezers, ANSI/UL 250.
