Appliances regulated by the IMC must be classified as what?

Appliances regulated by the International Mechanical Code (IMC) must be classified as listed and labeled. This means that these appliances have been tested and certified by a recognized testing laboratory to meet specific safety and performance standards. The "listed" aspect indicates that the appliance is included on a list of acceptable products compiled by an entity that tests to industry standards, while "labeled" refers to the presence of a label on the appliance indicating that it meets the required safety standards. This classification ensures that the appliances are safe for use and comply with the regulatory requirements outlined in the IMC, providing confidence to both installers and consumers regarding the reliability of the appliances in question.
