Describes 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.

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).
