Part 2-58: Particular requirements for commercial
electric dishwashing machines
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60335-2-58 has been prepared by IEC Committee 61: Safety of
household and similar electrical appliances.
This fourth edition cancels and replaces the third edition published in 2002 including its
Amendment 1 (2008) and its Amendment 2 (2015). This edition constitutes a technical
revision.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance 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.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

SAFETY –
Part 2-58: Particular requirements for commercial
electric dishwashing machines
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrically operated dishwashing
machines for washing plates, dishes, glassware, cutlery and similar articles, with or without
means for water heating or drying, not intended for household use, their rated voltage being
not more than 250 V for single-phase appliances connected between one phase and neutral
and 480 V for other appliances.
NOTE 101 These appliances are used for example in restaurants, canteens, hospitals, and commercial
enterprises such as bakeries, butcheries, etc.
NOTE 102 Examples of such appliances are
– conveyor dishwashers;
– batch dishwashers;
– brush machines.
Requirements to avoid backsiphonage of non-potable water into the water mains are specified
in Annex BB.
The electrical part of appliances making use of other forms of energy is also within the scope
of this standard.
As far as is practicable, this standard deals with the common hazards presented by these
types of appliances.
NOTE 103 Attention is drawn to the fact that:
– for appliances 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;
– in many countries, additional requirements are specified for pressure appliances.
NOTE 104 This standard does not apply to:
– appliances designed exclusively for industrial purposes, for example machines used in the food industry for
cleaning receptacles that serve as packaging for final products (e.g. bottle-cleaning machines), and machines
used in manufacturing processes;
– sterilizers and washer-disinfectors used to treat medical materials (IEC 61010-2-040);
– dishwashers that do not form one functional unit, for example where a transportation device transfers the load
from one separate unit to another;
– separately driven transport devices not confined in the appliance;
– 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).

Appliances with type X attachment, except those having a specially prepared cord, are fitted
with the lightest permissible type of flexible cable or cord of the smallest cross-sectional area
specified in Table 13, and other appliances are tested as delivered.
Detachable parts are removed.
Appliances intended to be filled with water by the user are completely filled with the spillage
solution. A further quantity of the solution, equal to 5 % of the capacity of the appliance or 10 l,
whichever is the greater, is then poured in steadily over a period of 1 min.
Other appliances are operated through one complete cycle of normal operation, after which
the timer switch, float or pressure-operated switch is made inoperative, and 5 g of the
standard detergent given in IEC 60436 is added per litre of water in the appliance at the
highest level of fill during normal operation and the appliance is operated in the intended
manner.
Only one switch is rendered inoperative at a time.
If a means is not provided to prevent overfilling of the appliance, the fill is continued for an
additional 15 min following the first evidence of overflow. If a float or pressure-operated
switch is provided to prevent overfilling, actuation of the fill switch to terminate the fill shall
also terminate the test. If both timer and fill switch are provided, a second test shall be

conducted as described above with the timer operating normally and with the fill switch
rendered inoperative.
Immediately after this test, the appliance shall withstand the electric strength test as specified
in 16.3 and inspection shall show that there is no trace of water on insulation that could result
in a reduction of clearances or creepage distances below the values specified in Clause 29.
For appliances, the tops of which are intended to form working surfaces, a quantity of 0,2 l of
the spillage solution is poured steadily from a height of about 50 mm on to the middle of the
top of the appliance for a period of 15 s.
Immediately after this test, the appliance shall withstand the electric strength test as specified
in 16.3 and inspection shall show that there is no trace of water on insulation that could result
in a reduction of clearances or creepage distances below the values specified in Clause 29.
15.101 Appliances that are provided with a tap intended for filling or cleaning shall be
constructed so that the water from the tap cannot come into contact with live parts.
Compliance is checked by the following test.
The tap is fully opened for 1 min with the appliance connected to a water supply having the
maximum water pressure indicated. Tiltable and movable parts, including lids, are tilted or
placed in the most unfavourable positions. Swivelling outlets of water taps are so positioned
as to direct water on to those parts that will give the most unfavourable result. Immediately
following this treatment, the appliance shall withstand the electric strength test of 16.3.
16 Leakage current and electric strength
This clause of Part 1 is applicable except as follows.
16.2 Modification:
Instead of the permissible leakage current for stationary class I appliances, the following
applies:
− for cord and plug connected appliances 1 mA per kW rated power input of the
appliance with a maximum of 10 mA,
− for other appliances 1 mA per kW rated power input of the
appliance with no maximum.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
18 Endurance
This clause of Part 1 is applicable.
19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.1 Addition:
– 16 – IEC 60335-2-58:2017 © IEC 2017
Appliances with a programme controller or timer are also subjected to the test of 19.101.
For conveyor dishwashers incorporating heating elements, the tests of 19.2, 19.3, and
where applicable 19.4, 19.5 and 19.6 may be made at rated voltage. In this case, the
addition to 19.13 applies.
19.2 Addition:
Appliances are filled with just sufficient water to cover the heating elements.
19.4 Addition:
The main contacts of the contactor intended for switching on and off the heating element(s) in
normal use are locked in the "ON" position. However, if two contactors operate independently
of each other or if one contactor operates two independent sets of main contacts, these
contacts are locked in the "ON" position in turn.
19.7 Modification:
Starting with the appliance at the ambient temperature specified in 5.7, it is supplied at rated
voltage or at the upper limit of the rated voltage range, with moving parts locked.
For each of the tests, appliances without a programme controller or timer are operated for 5
min and appliances provided with a programme controller or timer are operated for a time
equal to the maximum period allowed by the programme controller or timer.
19.13 Addition:
For conveyor dishwashers supplied at rated voltage, the appliance shall not emit any
poisonous or ignitable gas during the tests.
In addition, for basic insulation, the test voltage for the electric strength test in 16.3 is
1 000 V plus rated voltage.
19.101 Appliances provided with a programme controller or a timer shall be so constructed
that the risk of fire, mechanical hazard or electric shock is obviated as far as is practicable in
the event of incorrect operation, or the development of defects in control devices, such as
programme controllers and timers, or in their associated devices.
Compliance is checked by applying any form of operation or any defect that may be expected
in normal use, while the appliance is operated under normal operation and at rated voltage
or at the upper limit of the rated voltage range. Only one fault condition is reproduced at a
time, the tests being made consecutively.
During the tests, the appliance shall not emit flames or molten metal and the temperature of
windings shall not exceed the values shown in Table 8.
NOTE 1 Examples of fault conditions are
– the programme controller stopping in any position;
– the disconnection and reconnection of one or more phases of the supply during any part of the programme;
– the open-circuiting or short-circuiting of components;
– the failure of a magnetic valve;
– the opening and reclosing of the door or lid during any part of the programme, if this is possible.
NOTE 2 In general, tests are limited to those cases that may be expected to give the most unfavourable results.
NOTE 3 If operation without water in the appliance is considered to be a more severe condition for starting any
programme, the tests with that programme are made with the water inlet valve closed; however, this valve is not

IEC 60335-2-58:2017 © IEC 2017 – 17 –
closed after the programme has been started. If the appliance stops at any particular point in the programme, the
test with that fault condition is considered to be ended.
NOTE 4 For the purpose of these tests, thermal controls are not short-circuited.
NOTE 5 Components complying with the relevant IEC standards are not open-circuited or short-circuited,
provided the appropriate standard covers the conditions that occur in the appliance.
NOTE 6 The test, during which the automatic filling device is held open, has already been made during the test
of 15.2.
NOTE 7 The test with motor capacitors short-circuited or open-circuited has already been made during the test
of 19.7.
20 Stability and mechanical hazards
This clause of Part 1 is applicable except as follows.
20.1 Replacement:
Appliances other than those intended to be fixed to their supporting surface shall have
adequate stability.
