28、rsons. 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 situations that can be
29、 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 appliance is connected
30、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 another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as far as is reasonable. If applicable, the influ
31、ence of one function on the other is taken into account. 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 necessar
32、y 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 takes precedence over horizontal and generic standards covering the same subject. NOTE 2 Horizontal and gen
33、eric 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, su
34、ch as ISO 13732-1 for hot surfaces, are not applicable 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
35、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 may be examined and tested according to the intent of the requirements and, if found to be subst
36、antially equivalent, may be considered to comply with the standard. For electrolysers, 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 o
37、f the appliance should be reduced if an incorporated electrolyser including its protection system or control system, if any, complies with this standard. In particular, the construction detail inspection and testing may be done separately on the electrolysers, thereby eliminating the need for inspec
38、tion and testing when the electrolysers is applied to different appliances. BS EN 60335-2-108:2008 5 HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2-108: Particular requirements for electrolysers 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals
39、with the safety of electrolysers that produce low viscosity, ionized liquids intended for use as detergent free wash water in appliances for household and similar purposes and which conform with the standards applicable to such appliances. It applies to electrolysers tested separately, under the mos
40、t severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V. NOTE 101 Examples of appliances that may contain electrolysers are dishwashers (IEC 60335-2-5); washing machines (IEC 60335-2-7); appliances producing wash water for hygiene purposes. NOTE
41、 102 This standard does not supersede the requirements of standards relevant to the particular appliance in which the electrolyser is used. However, if the electrolyser used complies with this standard, the tests for the electrolyser specified in the particular appliance standard may not need to be
42、made in the particular appliance or assembly. If the electrolyser control system is associated with the particular appliance control system, additional tests may be necessary on the final appliance. A guide for additional requirements to be considered for inclusion in the end product standards for a
43、ppliances that use electrolysers is given in Annex BB. NOTE 103 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; in many countries, additional requirements are specified by the national health
44、authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities. NOTE 104 This standard does not apply to appliances intended exclusively for industrial purposes; appliances intended to be used in locations where special c
45、onditions 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 except as follows.
