Household and similar electrical appliances - Safety - Particular requirements for commercial electric tumble dryers
This European Standard deals with the safety of electrical operated tumble dryers intended to be used by trained 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 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 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 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 tumble dryers safely without supervision or instruction; b) children playing 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, the 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 standard does not apply to: – industrial laundry machinery (EN ISO 10472-4), – 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).

La présente Norme Européenne traite de la sécurité des sèche-linge à tambour électriques destinés à être utilisés par des usagers avertis, par exemple, dans des hôtels, des hôpitaux, chez des artisans et dans des fermes. Elle couvre également les sèche-linge à tambour déclarés pour un usage collectif dans des lieux publics et utilisés par des usagers non avertis, par exemple, dans des laveries automatiques et des buanderies mises à la disposition commune des usagers. La tension assignée ne doit pas être supérieure à 250 V pour les appareils monophasés et à 480 V pour les autres appareils. La présente norme traite également de la sécurité des sèche-linge à tambour utilisant un système de réfrigération à motocompresseur hermétique pour sécher le linge. Ces machines peuvent utiliser des fluides frigorigènes inflammables. Des exigences supplémentaires pour ces machines sont données à l’Annexe BB. La présente norme couvre également les sèche-linge à tambour utilisant d’autres sources d’énergie. Elle ne couvre pas les exigences relatives à ces autres sources d’énergie. Toutefois, elle couvre l’influence de ces autres sources d’énergie sur les machines. La présente norme traite des dangers ordinaires présentés par les sèche-linge à tambour et auxquels sont confrontés tous les individus. Cependant, cette norme ne tient pas compte en général: a) des personnes (y compris des enfants) dont: 1) les capacités physiques, sensorielles ou mentales; ou 2) le manque d’expérience et de connaissance les empêchent d’utiliser les sèche-linge à tambour en toute sécurité sans surveillance ou instruction; b) de l’utilisation des sèche-linge à tambour comme jouet par des enfants. L’attention est attirée sur le fait que: – pour les sèche-linge à tambour électriques à usage collectif destinés à être utilisés dans des véhicules ou à bord de navires ou d’avions, des exigences supplémentaires peuvent être nécessaires; dans de nombreux pays, des exigences supplémentaires sont spécifiées par les organismes nationaux de la santé, par les organismes nationaux responsables de la protection des travailleurs, par les organismes nationaux responsables de l’alimentation en eau, par les organismes nationaux responsables du transport et par les organismes nationaux responsables du bâtiment. La présente norme ne s’applique pas: – aux machines de blanchisserie industrielle (EN ISO 10472-4); – aux sèche-linge destinés à être utilisés dans des locaux présentant des conditions particulières comme par exemple la présence d’une atmosphère corrosive ou explosive (poussières, vapeur ou gaz).
Gospodinjski in podobni električni aparati - Varnost - Posebne zahteve za komercialne električne sušilnike perila
Ta mednarodni standard obravnava varnost električnih sušilnih strojev, naj bi jih uporabljali strokovno usposobljeni uporabniki, npr. v hotelih, bolnišnicah, tovarnah, lahki industriji in na kmetijah. Pokriva tudi sušilne stroje, namenjene komercialni uporabi na javnih mestih, ki jih uporabljajo nestrokovne osebe, npr. v javnih pralnicah. Njihova nazivna napetost ne sme presegati 250 V za enofazne naprave in 480 V za vse druge naprave. Ta standard opisuje tudi varnost sušilnih strojev s hladilnim sistemom, ki vključuje zatesnjene motorne kompresorje za sušenje tekstilnih materialov. Te stroji lahko uporabljajo vnetljiva hladila. Dodatne zahteve za te stroje so navedene v dodatku BB. Ta standard pokriva tudi sušilne stroje, ki uporabljajo druge vire energije. Ta standard ne zajema zahtev za te druge vire energije. Zajema pa vpliv drugih virov energije na stroje. Ta evropski standard obravnava splošna tveganja, ki jih predstavljajo sušilni stroji za vse ljudi. Vendar na splošno ne upošteva:
a) oseb (tudi otrok), ki zaradi:
1) fizičnih, senzoričnih ali umskih sposobnosti oziroma
2)pomanjkanja izkušenj in znanja
ne morejo varno uporabljati sušilnih strojev brez nadzora ali navodil;
b) otrok, ki se igrajo s sušilnim strojem.
Upoštevati je treba tudi:
– da so za komercialne električne sušilne stroje, ki so namenjeni za uporabo v vozilih ali na krovu ladij ali letal, morda potrebne dodatne zahteve;
– da v številnih državah nacionalni zdravstveni organi, nacionalni organi, odgovorni za varstvo pri delu, nacionalni organi za oskrbo z vodo, nacionalni organi, pristojni za transport in nacionalni organi za stavbe določajo dodatne zahteve.
Ta evropski standard se ne uporablja za:
c) industrijske pralne stroje (EN ISO 10472-4),
d) sušilne stroje za uporabo na mestih, kjer prevladajo posebni pogoji, kot je
prisotnost korozivne ali eksplozivne atmosfere (prah, hlapi ali plin). V tem standardu izraz »naprava«, kot je uporabljen v 1. delu, pomeni »sušilne stroje, namenjene komercialni uporabi«.

– 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 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 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
manufacturer's 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 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 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 machinery is connected to the supply mains. However, national
wiring rules may differ.
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
trained 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 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 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 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 tumble dryers safely without supervision or instruction;
b) children playing with the tumble dryer.
Attention is drawn to the fact that:
