CSA C22.2 No. 60335-2-34:25

1 Scope This clause of Part 1 is replaced by the following. This part of IEC 60335 deals with the safety of sealed (hermetic and semi-hermetic type) MOTORCOMPRESSORS, 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 MOTORCOMPRESSORS and 600 V for other MOTOR-COMPRESSORS. This standard also covers – multi-speed MOTOR-COMPRESSORS, that are MOTOR-COMPRESSORS, the speed of which can be set to different values; – variable capacity MOTOR-COMPRESSORS that are MOTOR-COMPRESSORS where the capacity of the compressor is controlled at fixed speeds. NOTE 101 Examples of equipment which contain MOTOR-COMPRESSORS are – tumble dryers (IEC 60335-2-11); – refrigerating appliances, ice-cream appliances and ice-makers (IEC 60335-2-24); – electrical heat pumps, air-conditioners and dehumidifiers (IEC 60335-2-40); – commercial dispensing appliances and vending machines (IEC 60335-2-75); – commercial refrigerating appliances and ice-makers with an incorporated or remote refrigerant unit or compressor (IEC 60335-2-89); – electrical equipment for measurement, control, and laboratory use (IEC 61010–2–011); – professional ice-cream makers (IEC 60335-2-118); – refrigerating systems and heat pumps (ISO 5149–2). 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 could 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 – the use of appliances by young children or infirm persons without supervision; – playing with the appliances by young children. NOTE 102 Attention is drawn to the fact that – for MOTOR-COMPRESSORS intended to be used in appliances in vehicles or on board ships, additional requirements could be necessary; – in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities. This standard does not apply to – MOTOR-COMPRESSORS designed exclusively for industrial purposes; – 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 103 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. 1DV DR Modification by replacing Clause 1 of the Part 2 with 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 15 000 V, single or multi-phase and direct current (DC). MOTOR-COMPRESSORS covered by this standard are intended for use in accordance with: – CSA C22.1, Canadian Electrical Code, Part I, in Canada; – NFPA 70, National Electrical Code (NEC), in the United States. This standard is unique in that it applies to MOTOR-COMPRESSORS which are components used within an end-use appliance having its own safety certification standard. Thus, this standard does not distinguish whether a specific MOTOR-COMPRESSOR is intended for use in household, commercial or industrial applications. MOTOR-COMPRESSOR usage is defined by the end-use standard. MOTOR-COMPRESSORS with a rated voltage from 600 to 15 000 V shall use Annex 101.DVI together with other relevant requirements in this standard. This standard also covers – multi-speed MOTOR-COMPRESSORS, that are MOTOR-COMPRESSORS, the speed of which can be set to different values; – variable capacity MOTOR-COMPRESSORS, that are MOTOR-COMPRESSORS where the capacity of the compressor is controlled at fixed speeds; – MOTOR-COMPRESSORS used in an appliance not intended for normal household use but which nevertheless can be a source of danger to the public. These appliances are intended to be used by lay people in shops, in light industry, farms, and similar applications. NOTE 101 Examples of equipment which contain MOTOR-COMPRESSORS are, – tumble dryers (IEC 60335-2-11); – refrigerating appliances, ice-cream appliances, and ice-makers (CSA C22.2 No. 60335-2-24/ UL 60335-2-24); – electrical heat pumps, air-conditioners, and dehumidifiers (CSA C22.2 No. 60335-2-40/ UL 60335-2-40); – commercial dispensing appliances, and vending machines (IEC 60335-2-75); – commercial refrigerating appliances and ice makers with an incorporated or remote refrigerant unit or compressor (CSA C22.2 No. 60335-2-89/ UL 60335-2-89). – electrical equipment for measurement, control, and laboratory use (CSA C22.2 No. 61010-2-011/ UL 61010-2-011); – professional ice-cream makers (IEC 60335-2-118); – refrigerating systems and heat pumps (ISO 5149-2). 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 could be necessary on the final appliance. So far as is practical, this standard deals with the common hazards presented by MOTORCOMPRESSORS used in appliances which are encountered by all persons in and around the home. However, it does not in general take into account – the use of appliances by young children or infirm persons without supervision; – playing with the appliances by young children. NOTE 102 Attention is drawn to the fact that. – for MOTOR-COMPRESSORS intended to be used in appliances in vehicles or on board ships, additional requirements could be necessary; – in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities. This standard does not apply to – 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 103 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.
