33、HANGE CHINA STANDARDS, 03/03/2009 08:09, Uncontrolled Copy, (c) BSI60335-2-26 IEC:2002(E) 5 INTRODUCTION It has been assumed in the drafting of this International Standard that the execution of its provisions is entrusted to appropriately qualified and experienced persons. This standard recognizes t

34、he internationally accepted 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 i

35、nto account the way in 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, nat

36、ional wiring rules may 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

37、 is taken into account. 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 these requirements. An

38、 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 the standard. When a

39、 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 in quest

40、ion 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 since they

41、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 in addit

42、ion to Part 1 or art 2 standards.

43、s replaced by the following. This International Standard deals with the safety of electric clocks having a rated voltage not more than 250 V. NOTE 101 Examples of appliances that are within the scope of this standard are a l a r m c l o c k s ; spring-driven clocks with an electrically operated wind

44、ing mechanism; clocks incorporating driving means other than motors. 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 102 Attention is draw

45、n to the fact that for 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

46、 similar authorities. NOTE 103 This standard does not apply to battery-operated clocks; 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

47、gas); clocks having other functions, whether or not in combination with time indication, such as master control clocks and timers for cooking ranges, washing machines and similar appliances; clocks for “clocking-in“ purposes; clocks incorporating electronic circuits only (IEC 60065). 2 Normative ref

48、erences This clause of Part 1 is applicable. 3 Definitions This clause of Part 1 is applicable except as follows. persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or inst

49、ruction; children playing with the appliance. ! “ Page 7 BS EN 60335-2-26:2003+A1:2008 Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 03/03/2009 08:09, Uncontrolled Copy, (c) BSI60335-2-26 IEC:2002(E) 7 3.1.9 Replacement: normal operation operation of the clock under the following conditions Spring-driven clocks having an electrically operated winding mechanism are operated as in normal
