33、LECTRICAL APPLIANCES SAFETY Part 2-79: Particular requirements for high pressure cleaners and steam cleaners FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees).
34、The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Spec
35、ifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizatio
36、ns liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters
37、 express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National C
38、ommittees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC Na
39、tional Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself do
40、es not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they h
41、ave the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature what
42、soever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced public
43、ations is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Stan
44、dard IEC 60335-2-79 has been prepared by subcommittee 61J: Electrical motor-operated cleaning appliances for commercial use, of IEC technical committee 61: Safety of household and similar electrical appliances. This fourth edition cancels and replaces the third edition published in 2012. It constitu
45、tes a technical revision. The principal changes in this edition as compared with the third edition of IEC 60335-2-79 are as follows (minor changes are not listed): the standard has been revised editorially to avoid misunderstandings; the document has been revised for the consistent use of definition
46、s throughout the text; correct references were added in the foreword; COMMEMORATIVE COPY IEC 60335-2-79:2016 IEC 2016 5 Annex B has been revised and updated; Clause 15 has been revised and updated; clarification of relevant liquid tanks has been added; in Clause 20 the revised temperature has been i
47、nserted; the text in 29.1 was modified in order to remove any misunderstandings and is in line with IEC 60335-2-102. The text of this standard is based on the following documents: FDIS Report on voting 61J/635/FDIS 61J/645/RVD Full information on the voting for the approval of this standard can be f
48、ound in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fifth edition (20
49、10) of that standard. NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1. This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to convert that publication into the IEC standard: Safety requirements for high pressure cleaners and steam cleaners. When a particular sub clause of Part 1 is not mentioned in this part 2, that sub cl
