16、onsultant, taking also into account the results of CENELEC TC61/WG6 work on EN 60335-1. The approach to amend EN 60335-2-68:2003 aiming toward listing the standard under the MD was discussed and approved during the Kista meeting of CENELEC TC 61 in June 2008 (see CLC/TC 61/SEC/1649), when it was dec
17、ided to submit a draft for an amendment to the Unique Acceptance Procedure. The draft was circulated as FprAB in December 2008 and was approved by CENELEC as a new edition of EN 60335-2-68 on 2009-09-01. This European Standard supersedes EN 60335-2-68:2003 + A1:2006 + corrigendum December 2006 + A2:

20、 1: General requirements. It was established on the basis of the 2002 edition of that standard. Amendments and revisions of Part 1 have also to be taken into account and the dates when such changes become applicable will be stated in the relevant amendment or revision of Part 1. This Part 2 suppleme
21、nts or modifies the corresponding clauses of EN 60335-1, so as to convert it into the European Standard: Safety requirements for spray extraction machines for commercial use. When a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies. When this standard states “add
22、ition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. This European Standard has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 2006/42/EC

34、lled Copy, (c) BSIEN 60335-2-68:2009 6 Introduction It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced persons. This standard recognizes the internationally accepted level of protection against ha
35、zards such as electrical, mechanical, thermal, fire and radiation of machines 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 into account the way in which electromagnetic phenomena can a
36、ffect the safe operation of machines. 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 machine is connected to the supply mains. However, national wiring rules may differ. If a machine within the scope of
37、this standard also incorporates functions that are covered by another Part 2 of EN 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 is taken into account. This standard is a product family standard d
38、ealing with the safety of machines and takes precedence over horizontal and generic standards covering the same subject. A machine 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
39、found to have other features that impair the level of safety covered by these requirements. A machine 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
40、found to be substantially equivalent, may be considered to comply with the standard.

41、y extraction machines for commercial use 1 Scope This clause of Part 1 is replaced by the following. This European Standard deals with the safety of electrical portable, non self-propelled motor-operated spray extraction machines with or without attachments and with or without electrical heating ele
42、ments, intended for commercial indoor use. NOTE Z101 Commercial use of spray extraction machines is for example their use in hotels, schools, hospitals, factories, shops and offices for other than normal housekeeping purposes and rental services for those machines. The following power systems are co
43、vered: mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances, battery powered motors. This standard applies to machines in which the pressure of the employed cleaning agent does not exceed 2,5 MPa, and in which the product of the pressure (in
44、MPa) and the flow of cleaning agent (in litres per minute) does not exceed 100, and in which the temperature of the cleaning agent at the spray nozzle outlet does not exceed 85 C. NOTE Z102 Attention is drawn to the fact that in many countries additional requirements on the safe use of the equipment
45、 covered may be specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities. This standard does not apply to machines designed to be part of a production process; wet and dry vacuum cle
46、aners as covered by IEC 60335-2-69; machines designed for picking up hazardous dusts, inflammable substances, or aflame particles; floor treatment machines for commercial use; NOTE Z103 IEC 60335-2-67 covers floor cleaning and floor treatment machines for industrial and commercial use. IEC 60335-2-7
47、2 covers automatic floor treatment machines for industrial and commercial use. machines designed for use in corrosive or explosive environments (dust, vapour or gas); hand-held appliances; hand-held and transportable motor-operated electric tools. NOTE Z104 The IEC 60745 series covers hand-held moto
48、r-operated electric tools; the IEC 61029 series covers transportable motor-operated electric tools. 2 Normative references This clause of Part 1 is applicable except as follows.
