Household and similar electrical appliances - Particular requirements for electrical operated commercial rotary ironers
This document deals with the safety of electrically operated commercial rotary ironers, intended to be used by
trained users in e.g. hotels hospitals, factories, in light industry and on farms. It also covers rotary ironers which
are declared for commercial use in areas open to the public and operated by lay persons e.g. in laundrettes and
communal laundry rooms. Their rated voltage being not more than 250 V for single phase and 480 V for others.
This document also covers electrically operated commercial rotary ironers making use of other energy sources.
It does not cover requirements for these other energy sources for heating purposes. However, the influence of
these other energy sources on the machine is covered.
As far as is practicable, this document deals with the common hazards presented by appliances that are
encountered by all persons in household and similar environments.
However, in general, it does not take into account
— children playing with the appliance,
— the use of the appliance by children,
It is recognized that very vulnerable people may have needs beyond the level addressed in this document.
Products covered by this document do not create a noise hazard, therefore no specific provisions concerning
noise are given.
NOTE 101 Attention is drawn to the fact that
— for electrically operated commercial rotary ironers intended to be used in vehicles or on board ships or aircraft, additional
requirements can be necessary;
— in many countries additional requirements are specified by the national health authorities, the national authorities
responsible for the protection of labour and similar authorities.
This document does not apply to
— industrial flatwork ironers having a surface contact area ≥ 1,20 m2, feeders and folders (EN ISO 10472-5);
— appliances 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 document, the term “appliance” as used in Part 1 is read as “electrically operated
commercial rotary ironers”.
