实施时间:摘要: Household and Similar Electrical Appliances, Part 2-40: Particular Requirements for Electrical Heat Pumps, Air-Conditioners and DehumidifiersUL 60335-2-401 ScopeThis International Standard deals with the safety of electric HEAT PUMPS, including SANITARY HOT WATER HEAT PUMPS, AIR-CONDITIONERS, and DEHUMIDIFIERS incorporating motor-compressors and hydronic room FAN COILS, their maximum RATED VOLTAGES being not more than 250 V for single phase appliances and 600 V for all other appliances.Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.This standard also applies to electric HEAT PUMPS, AIR CONDITIONERS and DEHUMIDIFIERS containing FLAMMABLE REFRIGERANT. FLAMMABLE REFRIGERANTS are defined in 3.120.The appliances referenced above may consist of one or more factory made assemblies. If provided in more than one assembly, the separate assemblies are to be used together, and the requirements are based on the use of matched assemblies. A definition of motor-compressor is given in IEC 60335-2-34, which includes the statement that the term motor-compressor is be used to designate either a hermetic motor-compressor or semi-hermetic motor-compressor. Requirements for refrigeration safety are covered by ISO 5149, and requirements for containers intended for storage of the heated water included in sanitary hot water heat pumps are, in addition, covered by IEC 60335-2-21.This standard does not take into account chemicals other than group A1, A2, or A3 as defined by 3.121. This standard specifies particular 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.The sections and clauses in ISO 5149 of particular concern to this standard are as follows:Section 3: Design and construction of equipment applies to all appliances and systems.Section 4: Requirements for utilization applies to appliances and systems which are for "similar electrical appliances", i.e. commercial and light industrial.Section 5: Operating procedures applies to appliances and systems which are for "similar electrical appliances", i.e. commercial and light industrial.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. Attention is drawn to the fact that:for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;for appliances subjected to pressure, additional requirements may be necessary;in many countries additional requirements are specified, for example, by the national health authorities responsible for the protection of labour and the national authorities responsible for storage, transportation, building constructions and installations.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). -

实施时间:摘要: Low-Voltage Switchgear and Controlgear - Part 4-1: Contactors and Motor-Starters - Electromechanical Contactors and Motor-StartersUL 60947-4-1ScopeThis part of IEC 60947 applies to the types of equipment listed in 1.1.1 and 1.1.2 whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.Starters and/or contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 9.3.4) forms part of the installation but not necessarily of the contactor or the starter.In this context, this standard gives requirements for:contactors associated with overload and/or short-circuit protective devices;starters associated with separate short-circuit protective devices and/or with separate short-circuit and integrated overload protective devices;contactors or starters combined, under specified conditions, with their own short-circuit protective devices.Such combinations, e.g. combination starters or protected starters are rated as units. -

实施时间:摘要: Standard for Low-Voltage Switchgear and Controlgear - Part 4-2: Contactors and Motor-Starters - AC Semiconductor Motor Controllers and StartersUL 60947-4-21 Scope and objectThis standard applies to controllers and starters, which may include a series mechanical switching device, intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c.This standard characterizes controllers and starters with and without bypass means.Controllers and starters dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 8.2.5) should form part of the installation, but not necessarily of the controller or starter.In this context, this standard gives requirements for controllers and starters associated with separate short-circuit protective devices.This standard does not apply to:continuous operation of a.c. motors at motor speeds other than the normal speed;semiconductor equipment, including semiconductor contactors (see 2.2.13 of IEC 60947-1) controlling non-motor loads;electronic a.c. power controllers covered by IEC 60146.Contactors, overload relays and control circuit devices used in controllers and starters should comply with the requirements of their relevant product standard. Where mechanical switching devices are used, they should meet the requirements of their own IEC product standard, and the additional requirements of this standard.The object of this standard is to state as follows:the characteristics of controllers and starters and associated equipment;the conditions with which controllers and starters shall comply with reference to:their operation and behaviour;their dielectric properties;the degrees of protection provided by their enclosures where applicable;their construction;the tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests;the information to be given with the equipment, or in the manufacturer's literature. -
