22、eans of conforming to essential safety requirements of the Machinery Directive 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 washing

23、 machines and takes precedence over horizontal and generic standards covering the same subject. This standard recognises the level of protection against hazards such as electrical, mechanical, thermal, fire and radiation of commercial electric washing machines when operated as in normal use taking i

24、nto account the manufacturers instructions. It also covers any reasonably foreseeable misuse of the machinery and takes into account the way in which electromagnetic phenomena can affect the safe operation of commercial electric washing machines. A commercial electric washing machine that complies w

25、ith 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 features that impair the level of safety covered by these requirements. This standard takes into account the requirements of H

26、D 60364-1 as far as possible so that there is compatibility with the wiring rules when the machinery is connected to the supply mains. However, national wiring rules may differ. BS EN 50571:2013BS EN 50571:2013EN 50571:2013 6 1 Scope This clause of Part 1 is replaced by the following: This European

27、Standard deals with the safety of electrical operated washing machines intended to be used by trained users in e.g. hotels, hospitals, factories, in light industry and on farms. It also covers washing machines declared for commercial use in public areas and operated by lay persons e.g. in laundrette

28、s, communal laundry rooms. Their rated voltage being not more than 250 V for single phase and 480 V for others. This standard also covers washing machines making use of other energy sources. It does not cover requirements for these other energy sources or compressed air. However the influence of the

29、se other energy sources on the machines is covered. These washing machines are designed to be connected to hot and/or cold water supply. Washing machines making use of steam or hot water for heating purposes are also within the scope of this standard. This standard deals with the common hazards pres

30、ented by washing machines that are encountered 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 washing machine safely without s

31、upervision or instruction; b) children playing with the washing machine. Attention is drawn to the fact that: for commercial electric washing machines intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary, in many countries additional requirements ar

32、e specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities, for commercial electric washing machines having a drying function, EN 50570 (commercial electric tumble dryers) is also ap

33、plicable. This European Standard does not apply to: c) industrial laundry machinery (EN ISO 10472-2), d) washing machines 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 stan

34、dard, the term “appliance” is to be read as “washing machine intended for commercial use.

43、 which it is constructed. However, if the power input or current is higher when only 50 % of the textile material is used, the appliance is operated with this load instead The temperature of the water is: 65 C 5 C for appliances without heating elements, 15 C 5 C for other appliances, BS EN 50571:20

If the appliance does not incorporate a programmer, the water is heated to 90 C 5 C or as high as the construction will allow if lower, before starting the fi

45、rst washing period. The textile material consists of pre-washed double-hemmed cotton sheets having dimensions approximately 70 cm 70 cm and a specific mass between 140 g/m and 175 g/m in the dry condition. For impeller type appliances, if the textile material does not move properly during operation,

46、 the quantity of textile material may be reduced until the maximum power input of the motor is attained, or a textile material comprising pre-washed double-hemmed cotton sheets, having dimensions of approximately 90 cm x 90 cm and a mass between 90 g/m2and 110 g/m2in the dry condition, may be used.

47、However, for impeller type appliances, in case of doubt, the test should be carried out using the reduced quantity of textile material.
