35、and experienced persons. This standard recognizes the 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 situ
36、ations 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 the requirements of IEC 60364 as far as possible so that there is compatibility with the wiring rules when the appli
37、ance 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 far as is reasonable. If applicable, the influence of one function on the other is taken into account. An appliance that co
38、mplies 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 appliance employing materials or having for
39、ms 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. in Part 1, Part 1 applies. NOTE 1 not necessary to
40、 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 takes precedence over horizontal and generic standards covering the same subject. NOTE 2 Horizontal and generic
41、 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. For example, in the case of temperature requirements for surfaces on many appliances, generic standards, such a
42、s Page 6 BS EN 60335-2-51:2003+A1:2008 by another Part 2 of IEC 60335, the relevant Part 2 is applied to each function separately, as When a Part 2 standard does not include additional requirements to cover hazards dealt with This means that the technical committees responsible for the Part 2 standa
43、rds have determined that it is ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or Part 2 standards.

44、irements for stationary circulation pumps for heating and service water installations 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric stationary circulation pumps intended for use in heating systems or in service water systems
45、, having a rated power input not exceeding 300 W, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. NOTE 101 The hydraulic and electrical parts of the pump may be in the same enclosure, so that the water flows through the motor and serves as a
46、coolant, or they may be separated. Appliances not intended for normal household use, but that 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. As far as is practicab
47、le, 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 drawn to the fact that for appliances intended to be used in vehicles or on board ships or airc
48、raft, 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. NOTE 103 This standard does not apply to pumps for circulating liquid
49、s other than water; pumps, other than circulation pumps (IEC 60335-2-41); circulation pumps intended exclusively for industrial purposes; circulation pumps 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 1 is applicable. 3 Definitions This clause of Part 1 is applicable e
