EN 60335-2-40 Household and Similar Electrical Appliances - Safety - Part 2-40: Special Rules for Electric Heat Pumps, Air Conditioners and Dehumidifiers

The EN 60335-2-40 standard published by the International Electrotechnical Commission (IEC) covers the safety of electric heat pumps, including sanitary hot water heat pumps, air conditioners and dehumidifiers with motor compressors and hydronic room fans. The maximum rated voltages of these pumps do not exceed 250 Volts for single-phase devices and 600 Volts for all other devices. Appliances and machinery intended for use in homes, commercial applications, shops, light industry and farms are within the scope of this standard. Additional requirements for appliances and machines for commercial use are contained in the standard annex (Annex ZE).

Examples of devices for the home environment are devices for typical cleaning functions used in the home environment and devices for typical cleaning functions used by non-expert users. For example, devices used in shops, offices and similar working environments, farm houses, hotels, motels and other residential type environments and bed and breakfast type environments. The home environment includes the residence and associated buildings and the garden.

Supplementary heaters or a provision for their separate installation are covered by this standard, but only heaters, controls designed as part of the device package are included in the device.

The following points should be considered in the application of this standard:

• Additional requirements may be required for devices intended for use in vehicles or ships or aircraft.
• Additional requirements may be required for pressure-exposed devices.
• In many countries, additional requirements have been specified by, for example, national health authorities responsible for labor protection and national authorities responsible for storage, transportation, building construction and installations.

Meanwhile, devices not covered by this standard are:

• Humidifiers intended for use with heating and cooling equipment
• Devices designed for industrial processing only
• Devices intended for use where special conditions exist, such as the presence of a corrosive or explosive atmosphere
