A technician is deciding whether a household unit qualifies as a 'small appliance' under Section 608. Which description matches the EPA definition of a small appliance?

a.Any appliance holding less than 50 pounds of refrigerant that a homeowner can move
b.A field-assembled split system charged on site with up to 15 pounds of refrigerant
c.A product fully manufactured, charged, and hermetically sealed at the factory containing 5 pounds or less of refrigerant
d.Any appliance using an HFC refrigerant regardless of charge size

解析

EPA defines a small appliance as a product that is fully manufactured, charged, and hermetically sealed in a factory with five pounds or less of refrigerant. Household refrigerators, window air conditioners, and dehumidifiers are common examples. Field-charged split systems and larger units are not small appliances even if they hold little refrigerant.
