Overview

This scope of this standard deals with the safety of electric heat pumps, including sanitary hot water heat pumps, air conditioners, and dehumidifiers incorporating motor-compressors and hydronic fan coils units, their maximum rated voltages being not more than 250 V for single phase appliances and 600 V for all other appliances. Partial units are within the scope of this International Standard. These devices are used in domestic environments and for commercial purposes. The appliances referenced above can consist of one or more factory-made assemblies. If provided in more than one assembly, the separate assemblies are used together, and the requirements are based on the use of matched assemblies. Appliances and machinery intended for use by skilled personnel and/or trained individuals in workshops, small businesses, and agriculture, as well as equipment and machinery designated for commercial use by untrained individuals, fall within the scope of this standard. This standard deals with the reasonably foreseeable hazards presented by appliances and machinery, taking into account all affected persons. This standard contains specific requirements for the use of flammable refrigerants. Unless specifications are covered by this standard, including the annexes, requirements for refrigerating safety are covered by ISO 5149. Supplementary heaters, or a provision for their separate installation, are within the scope of this standard, but only heaters which are designed as a part of the appliance package, the controls being incorporated in the appliance. This standard does not apply to - humidifiers intended for use with heating and cooling equipment (IEC 60335-2-88); - appliances designed exclusively for industrial processing; - appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).
