This standard recognizes the internationally ac

31、cepted level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal use taking into account the manufacturers instructions It also covers abnormal situations that can be expected in practice and takes into account the way in

32、 which electromagnetic phenomena can affect the safe operation of appliances. This standard takes into account the requirements of IEC 60364 as far as possible so that there is compatibility with the wiring rules when the appliance is connected to the supply mains. However, national wiring rules may

33、 differ. If an appliance within the scope of this standard also incorporates functions that are covered by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as far as is reasonable. If applicable, the influence of one function on the other is taken into account

34、. When a part 2 standard does not include additional requirements to cover hazards dealt with in Part 1, Part 1 applies. NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is not necessary to specify particular requirements for the appliance

35、in question over and above the general requirements. This standard is a product family standard dealing with the safety of appliances and takes precedence over horizontal and generic standards covering the same subject. NOTE 2 Horizontal and generic standards covering a hazard are not applicable sin

36、ce they have been taken into consideration when developing the general and particular requirements for the IEC 60335 series of standards. For example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as ISO 13732-1 for hot surfaces, are not applicable

37、in addition to Part 1 or part 2 standards. An appliance that complies with the text of this standard will not necessarily be considered to comply with the safety principles of the standard if, when examined and tested, it is found to have other features that impair the level of safety covered by the

38、se requirements. An appliance employing materials or having forms of construction differing from those detailed in the requirements of this standard may be examined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with t

39、he standard. For motor-compressors, testing in accordance with this standard is an option and cannot be required as a precondition for testing the complete appliance, for example by reference in Clause 24 of a part 2 of IEC 60335. However, testing of the appliance should be reduced if an incorporate

40、d motor-compressor including its protection system or control system, if any, complies with this standard. If testing of the motor-compressor includes testing in accordance with Annex AA, temperatures of the motor-compressor windings, housing and other parts related to the motor-compressor, such as

41、terminals, internal wiring and insulating materials, are not measured when the complete appliance in which the motor-compressor is used is tested. These requirements apply to sealed (hermetic and semi-hermetic type) motor-compressors with their associated starting, cooling capacity control and prote

42、ction systems, tested separately under the most severe conditions of the refrigerating system operation which, within reasonable limits, could occur in the applications for which they are used. BS EN 60335-2-34:2013 8 60335-2-34 IEC:2012 In particular, the construction detail inspection and locked-r

43、otor testing may be done separately on the motor-compressor, thereby eliminating the need for inspection and testing when the motor-compressor is applied to many different appliances and factory-built assemblies. Operational tests may also be conducted on the motor-compressor separately in certain c

44、ircumstances. The specification for this type testing is provided in Annex AA. However, the tests of the existing standards relevant to the given kind of application, such as IEC 60335-2-24 and IEC 60335-2-40, may need to be conducted on the final application and used as the final determination of a

45、cceptability. BS EN 60335-2-34:201360335-2-34 IEC:2012 9 HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2-34: Particular requirements for motor-compressors 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of sealed (hermetic and s

46、emi-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 c

47、onditions 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 motor-compressors. NOTE 101 Examples of equipment which contain motor-compressors are refrigerators, food freezers and ice makers (IEC 60335-2-2

48、4); air-conditioners, electric heat pumps and dehumidifiers (IEC 60335-2-40); commercial dispensing appliances and vending machines (IEC 60335-2-75); factory-built assemblies for transferring heat in applications for refrigerating, air-conditioning or heating purposes or a combination of such purpos

49、es. 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 t
