Supersedes EN 60335-2-79:2009Foreword The text of document 61J/485/FDIS, future edition 3 of IEC 60335-2-79, prepared by SC 61J, “Electrical motor-operated cleaning appliances for commercial use“, of IEC/TC 61, “Safety of

14、 household and similar electrical appliances“ was submitted to the IEC-CENELEC parallel vote and approved by CENELEC as EN 60335-2-79:2012. A draft amendment, which covers common modifications to IEC 60335-2-79, was prepared by CLC/TC 61, “Safety of household and similar electrical appliances“ and a

15、pproved by CENELEC. The following dates are fixed: latest date by which this document has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2013-04-03 latest date by which the national standards conflicting with this document have to be with

16、drawn (dow) 2015-04-03 This document supersedes EN 60335-2-79:2009. The principal changes in EN 60335-2-79:2012 as compared with EN 60335-2-79:2009 are as follows (minor changes are not listed): the scope has been revised editorially to avoid misunderstandings; terms and definitions has been revised

17、 with regard to the requirements revised; the standard has been revised in general and updated regarding state-of-the-art, as far as necessary, in particular some changes have been made to Clauses 15, 22, and 25; a new Annex CC Emission of acoustical noise was added; a new Annex DD Emission of vibra

18、tion was added; a new Annex EE with a model test report for vibration emission was added. This part 2 is to be used in conjunction with the EN 60335-1:2012 and its amendments. NOTE 1 When “Part 1” is mentioned in this standard, it refers to EN 60335-1. This part 2 supplements or modifies the corresp

19、onding clauses in EN 60335-1, so as to convert that publication into the European Standard: Safety requirements for high pressure cleaners and steam cleaners. When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. When this standard sta

42、 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 appliances when operated as in normal use taking into

43、 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 the requirements of IEC 60364 as far as possibl

44、e 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 another part 2 of IEC 60335, the relevant part 2 is

45、 applied to each function separately, as far as is reasonable. If applicable, the influence 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

46、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 takes precedence ove

47、r 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. For example, in the

48、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 part 2 standards. An appliance that complies with the text of this standard will not necessarily be considered to comply with the saf

49、ety 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 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 standar
