This clause of Part 1 is replaced by the following. This International Standard deals with the safety of sealed (hermetic and semi-hermetic type) motor-compressors@ their protection and control systems@ if any@ which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to motor-compressors tested separately@ under the most severe conditions that may be expected to occur in normal use@ their rated voltage being not more than 250 V for single-phase motor-compressors and 480 V for other motorcompressors. NOTE 101 Examples of equipment which contain motor-compressors are ?C refrigerators@ food freezers and ice makers (IEC 60335-2-24); ?C air-conditioners@ electric heat pumps and dehumidifiers (IEC 60335-2-40); ?C commercial dispensing appliances and vending machines (IEC 60335-2-75); ?C factory-built assemblies for transferring heat in applications for refrigerating@ air-conditioning or heating purposes or a combination of such purposes. This standard does not supersede the requirements of standards relevant to the particular appliance in which the motor-compressor is used. However@ if the motor-compressor type used complies with this standard@ the tests for the motor-compressor specified in the particular appliance standard may not need to be made in the particular appliance or assembly. If the motor-compressor control system is associated with the particular appliance control system@ additional tests may be necessary on the final appliance. So far as is practical@ this standard deals with the common hazards presented by motor-compressors used in appliances which are encountered by all persons in and around the home. However@ it does not in general take into account ?C the use of appliances by young children or infirm persons without supervision; ?C playing with the appliances by young children. NOTE 102 Attention is drawn to the fact that ?C for motor-compressors intended to be used in appliances in vehicles or on board ships@ additional requirements may be necessary; ?C in many countries@ additional requirements are specified by the national health authorities@ the national authorities responsible for the protection of labour and similar authorities. NOTE 103 This standard does not apply to - motor-compressors designed exclusively for industrial purposes; ?C motor-compressors used in 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). NOTE 104 If motor-compressors for refrigerant R-744 used in appliances with a transcritical refrigeration system are equipped with pressure relief devices@ compliance with the requirements for these devices is checked during the tests on the final appliance.
