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 washing 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 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 washing machines.
A commercial electric washing machine 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
This clause of Part 1 is replaced by the following:
This European 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 laundrettes,
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 these 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 presented 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 supervision 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 are 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 applicable.

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

3 Terms and definitions
This clause of Part 1 is applicable except as follows:
3.1.9
normal operation
Addition:
the appliance is filled with textile material having a mass in the dry condition equal to the maximum mass
stated in the instructions, and with the maximum quantity of water for 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,

---------------------- Page: 9 ----------------------

SIST EN 50571:2014
EN 50571:2013 – 8 –

– 15 °C ± 5 °C for appliances without heating elements and intended for connection to the cold water
supply only.
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 first 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/m² and 175 g/m² in the dry condition.
For impeller type appliances, if the textile material does not move properly during operation,
– 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
2 2
approximately 90 cm x 90 cm and a mass between 90 g/m and 110 g/m in the dry condition, may be
used.
However, for impeller type appliances, in case of doubt, the test should be carried out using the reduced
quantity of textile material.
