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.
This part of International Standard IEC 60335 has been prepared by IEC technical committee
61: Safety of household and similar electrical appliances.
This sixth edition cancels and replaces the fifth edition published in 2002 including its
Amendment 1 (2005) and its Amendment 2 (2008). It 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 which 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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-5: Particular requirements for dishwashers

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric dishwashers for household and
similar purposes that are intended for washing and rinsing dishes, cutlery and other utensils,
their rated voltage being not more than 250 V for single-phase appliances and 480 V for
other appliances.
Appliances intended for normal household and similar use and that may also be used by
laymen in shops, in light industry and on farms, are within the scope of this standard.
However, if the appliance is intended to be used professionally for washing and rinsing dishes
and cutlery and other utensils that are used for commercial purposes, the appliance is not
considered to be for household and similar use only.
As far as is practicable, this standard deals with the common hazards presented by
appliances that are encountered by all persons in and around the home. However, in general,
it does not take into account
– persons (including children) whose
• physical, sensory or mental capabilities, or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
NOTE 101 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.
NOTE 102 This standard does not apply to
– commercial electric dishwashing machines (IEC 60335-2-58);
– appliances intended for industrial purposes;
– appliances intended to be used in locations where special conditions prevail, such as the presence of a

15.2 Replacement:
Appliances shall be constructed so that spillage of liquid in normal use does not affect their
electrical insulation, even if an inlet valve fails to close.
Compliance is checked by the following test.
Appliances with a type X attachment, except those having a specially prepared cord, are
fitted with the lightest permissible type of flexible cord of the smallest cross-sectional area
specified in Table 13.
Appliances intended to be filled with water by the user are completely filled with water
containing approximately 1 % NaCl. A further quantity of this solution equal to 15 % of the
capacity of the appliance or 0,25 l, whichever is greater, is poured in steadily over a period
of 1 min.
Other appliances are operated until the maximum water level is reached, and 5 g of the
detergent specified in Annex AA is added for each litre of water in the appliance. The inlet
valve is held open and the filling continued for 15 min after first evidence of overflow or until
the inflow is automatically stopped by other means.
For appliances that are loaded from the front, the door is then opened if this can be achieved
manually and without damage to the door interlock system.
For appliances having a working surface, 0,5 l of water containing approximately 1 % NaCl
and 0,6 % of rinsing agent, as specified in Annex AA, is poured over the top of the appliance,
the controls being placed in the on position. The controls are then operated through their
working range, this operation being repeated after a period of 5 min.
The appliance shall then withstand the electric strength test of 16.3 and inspection shall show
that there is no trace of water on insulation that could result in a reduction of clearances and
creepage distances below the values specified in Clause 29.
15.101 Appliances shall be constructed so that foaming does not affect electrical insulation.
Compliance is checked by the following test which is carried out immediately after that of
15.2.
The appliance is operated under the conditions specified in Clause 11 but for one complete
cycle with the programme that results in the longest period of operation. A solution consisting
of 20 g of NaCl and 1 ml of a solution of 28 % by mass of dodecyl sodium sulphate
(C H Na SO ), is added for each 8 l of water in the appliance. The solution used for this
12 25 2 4
test shall be stored in a cool atmosphere and used within seven days of its preparation.
For appliances incorporating a detergent dispenser, the solution is added manually at the
point in the cycle when it would normally be dispensed automatically. For other appliances,
the solution is added before starting the cycle.
The appliance shall then withstand the electric strength test of 16.3.
The appliance is then operated for two cycles under the same conditions, except that the
solution is not added. It shall then withstand the electric strength test of 16.3.
The appliance is kept in a test room having a normal atmosphere for 24 h before being
subjected to the test of 15.3.

This clause of Part 1 is applicable except as follows.

60335-2-5 © IEC:2012 – 13 –
20.1 Modification:
The appliance is empty or filled as specified for normal operation, whichever is more
unfavourable. Doors and lids are closed and any castors turned to the most unfavourable
position.
Addition:
For appliances that are loaded from the front, compliance is also checked by the test of
20.101.
20.101 The appliance is placed on a horizontal surface and a mass of 23 kg is placed on, or
suspended from, the centre of the open door or any fully opened drawer, whichever is more
unfavourable. Any castors are turned to the most unfavourable position.
For appliances normally used on a table or similar support and incorporating a door having
horizontal hinges and a horizontal rest position, a mass of 7 kg is used instead of a mass of
23 kg.
Appliances normally used on a table or similar support and which have a drawer are
additionally tested with the drawer placed in the most unfavourable position and loaded with
the maximum number of place settings in accordance with the instructions.
If a dishwasher is combined with a hob, the test is carried out with the appliance loaded as
specified in IEC 60436, the point of application of the mass being at the centre of the outer
edge of the open door or drawer.
The appliance shall not tilt.
20.102 Doors and lids shall be interlocked so that the appliance can only be operated when
the door or lid is closed, unless there is adequate protection against ejection of hot water
when the door or lid is opened.

Addition:
Parts that withstand the ageing test specified in Annex BB are not considered to be parts
where leakage could occur.
Drops of undiluted rinsing agent, as specified in Annex AA, are applied to the external surface
of the parts from which rinsing agent could leak if a seal fails.
After the test, and taking into account opening and closing the door, if any, during the test
there shall be no rinsing agent on the insulation of internal wiring or porous material in contact
with the internal wiring, if deterioration of the insulation could result in a hazard.
22.101 Appliances shall withstand the water pressure expected in normal use.
Compliance is checked by connecting the appliance to a water supply having a static pressure
equal to twice the maximum permissible inlet water pressure or 1,2 MPa, whichever is higher,
for a period of 5 min.
There shall be no leakage from any part, including the inlet water hose.
22.102 Appliances shall be constructed so that heating elements cannot come into contact
with combustible material inside the appliance as a result of deformation of the heating
elements or of parts supporting them.
Compliance is checked by inspection.
22.103 Appliances shall be constructed so that dishes and cutlery contacting heating
elements during the drying period do not give rise to a fire hazard.
Compliance is checked by the following test.
The appliance is placed on a piece of white pinewood board covered with tissue paper.
Polyethylene disks, approximately 80 mm in diameter and 2 mm thick, are placed at the most
unfavourable location, where possible directly in contact with the heating element. The
appliance is supplied at 1,1 times rated voltage and operated for a drying period under
normal operation.
When smoke or odour is evident, or when one-third of the drying period has elapsed,
whichever occurs first, the door or lid is opened.
Any flames, burning drops or glowing particles shall not spread fire to other parts of the
appliance. Flames, except from the disks, shall extinguish within 30 s of opening the door or
lid. The tissue paper shall not burn or the board become scorched.
The tissue paper shall comply with 4.215 of ISO 4046-4:2002 as thin, soft and strong
2 2
lightweight wrapping tissue with a mass per unit area between 12 g/m and 30 g/m .
The material of the disks used for the test is to be unfilled natural colour polyethylene without
flame-retardants and shall have a relative density of 0,96 ± 0,005.
22.104 If the microenvironment is pollution degree 3 the creepage distance along
uncemented or unwelded joints in switches is considered to be zero.
This requirement is not applicable to switches in low power circuits that are described in
19.11.1.
Compliance is checked by inspection.

23 Internal wiring
This clause of Part 1 is applicable except as follows.
23.3 Modification:
Instead of the test being carried out while the appliance is in operation, it is carried out with
the appliance disconnected from the supply.
The number of flexings is increased to 100 000.
Addition:
After the test, not more than 10 % of the strands of any conductor of the internal wiring
between the main part of the appliance and the door shall be broken.
23.101 The insulation and sheath of internal wiring for the supply of magnetic valves and
similar components incorporated in external hoses for connection to the water mains shall be
at least equivalent to light polyvinyl chloride sheathed flexible cord (code designation
60227 IEC 52).
Compliance is checked by inspection.
24 Components
This clause of Part 1 is applicable except as follows.
24.1.4 Addition:
The number of cycles of operation for programmers is 3 000.
The number of cycles of operation for door interlocks is 30 000.
24.101 Thermal cut-outs incorporated in dishwashers for compliance with 19.4 shall not be
self-resetting.
Compliance is checked by inspection.
25 Supply connection and external flexible cords
This clause of Part 1 is applicable.
26 Terminals for external conductors
This clause of Part 1 is applicable.
27 Provision for earthing
This clause of Part 1 is applicable.

28 Screws and connections
This clause of Part 1 is applicable.
29 Clearances, creepage distances and solid insulation
This clause of Part 1 is applicable except as follows.
29.2 Addition:
The microenvironment is pollution degree 3, and the insulation shall have a CTI not less than
250, unless the insulation is enclosed or located so that it is unlikely to be exposed to
pollution during normal use of the appliance due to
– condensation produced by the appliance;
– chemicals, such as detergent or rinse aid.
The requirement for a minimum CTI value of 250 is not applicable to functional insulation if
the working voltage does not exceed 50 V.
30 Resistance to heat and fire
This clause of Part 1 is applicable except as follows.
30.2 Addition:
For appliances incorporating a programmer or a timer, 30.2.3 is applicable. For other
appliances, 30.2.2 is applicable.
