19、) 2014-06-10 latest date by which the national standards conflicting with this document have to be withdrawn (dow) 2016-06-10 EN 50570:2013 is to be read in conjunction with EN 60335-1:2012 and its amendments, which is referred to in this text as “Part 1”. This standard supplements or modifies the c
20、orresponding clauses of Part 1 as indicated in the text. NOTE The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from
21、101, including those in a replaced clause or subclause; additional annexes are lettered AA, BB, etc. This document has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For the re
22、lationship with EU Directive(s) see informative Annex ZZ, which is an integral part of this document. _ BS EN 50570:2013BS EN 50570:2013 5 EN 50570:2013 Introduction This European Standard has been prepared to provide a means of conforming to essential safety requirements of the Machinery Directive
23、2006/42/EC. Other requirements and other EU Directives may be applicable to the machines within the scope of this standard. This standard is a product family standard dealing with the safety of commercial electric tumble dryers and takes precedence over horizontal and generic standards covering the
24、same subject. This standard recognises the level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of commercial electric tumble dryers when operated as in normal use taking into account the manufacturers instructions. It also covers any reasonably foreseeable
25、 misuse of the machinery and takes into account the way in which electromagnetic phenomena can affect the safe operation of commercial electric tumble dryers. A commercial electric tumble dryer that complies with the text of this standard will not necessarily be considered to comply with the safety
26、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. This standard takes into account the requirements of HD 60364-1 as far as possible so that there is compatibility with the wiring rules when the
27、machinery is connected to the supply mains. However, national wiring rules may differ. BS EN 50570:2013BS EN 50570:2013EN 50570:2013 6 1 Scope Replace this clause of Part 1 by the following: This European Standard deals with the safety of electrical operated tumble dryers intended to be used by trai
28、ned users in i.e. hotels, hospitals, factories, in light industry and on farms. It also covers tumble dryers which are declared for commercial use in public areas and operated by lay persons e.g. in laundrettes, communal laundry rooms. The rated voltage shall not be more than 250 V for single phase
29、and 480 V for others. This standard also deals with the safety of tumble dryers that use a refrigerating system, incorporating sealed motor-compressors, for drying textile material. These machines may use flammable refrigerants. Additional requirements for these machines are given in Annex BB. This
30、standard also covers tumble dryers making use of other energy sources. It does not cover requirements for these other energy sources. However the influence of these other energy sources on the machines is covered. This standard deals with the common hazards presented by tumble dryers that are encoun
31、tered by all persons. However, in general, it does not take into account: a) persons (including children) whose: 1) physical, sensory or mental capabilities, or 2) lack of experience and knowledge prevents them from using the tumble dryers safely without supervision or instruction; b) children playi
32、ng with the tumble dryer. Attention is drawn to the fact that: for commercial electric tumble dryers 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 authorities, t
33、he national authorities responsible for the protection of labour, the national water supply authorities, the national authorities responsible for transportation and the national authorities for buildings. This European Standard does not apply to: c) industrial laundry machinery (EN ISO 10472-4), d)
34、tumble dryers intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas). For the purpose of this standard, the term “appliance” as used in Part 1 is to be read as “tumble dryers intended for commercial use”. 2
