35、 drafting of this International Standard that the execution of its provisions is entrusted to appropriately qualified and experienced persons. This standard recognizes the internationally accepted level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of appl
36、iances 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 which electromagnetic phenomena can affect the safe operation of appliances.This standard takes into account
37、 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 differ. If an appliance within the scope of this standard also incorporates functions that are covered by ano
38、ther 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. An appliance that complies with the text of this standard will not necessarily be considered to comply with
39、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 these requirements. An appliance employing materials or having forms of construction differing from those detailed in the requirements of this standard ma
40、y be examined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with the standard. 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 t
41、hat the technical committees responsible for the Part 2 standards have determined that it is not necessary to specify particular requirements for the appliance in question over and above the general requirements. This standard is a product family standard dealing with the safety of appliances and ta
42、kes precedence over horizontal and generic standards covering the same subject. NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into consideration when developing the general and particular requirements for the IEC 60335 series of standards. Fo
43、r 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 in addition to Part 1 or art 2 standards.

44、PLIANCES SAFETY Part 2-28: Particular requirements for sewing machines 1 Scope This clause of Part 1 is replaced by: This International Standard deals with the safety of electric sewing machines for household and similar use, their rated voltage being not more than 250 V for single-phase appliances
45、and 480 V for other appliances. Overlock machines and electrical sets are within the scope of the standard. Appliances not intended for normal household use, but that nevertheless may be a source of danger to the public, such as sewing machines intended to be used by laymen in shops and in light ind
46、ustry, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account NOTE 101 Attention is drawn to the fact that for
47、appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may 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. N
48、OTE 102 This standard does not apply to appliances intended exclusively for industrial purposes; 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). 2 Normative references This clause of Part
