and water-suction cleaning appliances

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 redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

International Standard IEC 60335-2-2 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
This seventh edition cancels and replaces the sixth edition published in 2009, Amendment
1:2012 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– some requirements for appliances for animal grooming have been modified (6.1, 25.7)
– the note in 7.101 has been deleted;
– converted some notes to normative text (7.102, 10.1, 11.3, 13.1, 15.2, 15.101, 19.101,
20.1, 20.2, 21.103, 21.105, 22.32, 25.23);
– clarification that the test of 19.7 is applicable to vacuum cleaners with a motorized brush
or similar device;
– modified Annex R for alignment with 22.201 of Annex B;
– modified Annex S in accordance with IEC 60335-2-2:2009/ISH1:2016;
– requirements for mechanical strength of handles have been added (21.106).
The text of this International Standard is based on the following documents:

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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-2: Particular requirements for vacuum cleaners
and water-suction cleaning appliances

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric vacuum cleaners and
water-suction cleaning appliances for household and similar purposes, including vacuum
cleaners for animal grooming, their rated voltage being not more than 250 V. It also applies
to centrally-sited vacuum cleaners and automatic battery-powered battery-operated
cleaners.
This standard also applies to motorized cleaning heads and current-carrying hoses
associated with a particular vacuum cleaner.
Battery-operated appliances and other DC supplied appliances are within the scope of this
standard. Dual supply appliances, either mains-supplied or battery-operated, are regarded as
battery-operated appliances when operated in the battery mode.
Appliances not intended for normal household use, but which nevertheless may be a source
of danger to the public, such as appliances intended to be used by laymen in shops and other
premises for normal housekeeping purposes, are within the scope of this standard.
NOTE 101 Examples of such appliances are appliances intended to be used for normal housekeeping purposes in
hotels, offices, schools, hospitals and similar premises.
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 102 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may can
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 103 This standard does not apply to
– appliances intended exclusively for industrial purposes;
– 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);
– wet and dry vacuum cleaners, including power brush, for commercial use (IEC 60335-2-69).

operation of the appliance without the booster setting being used.
3.1.9 Replacement:
normal operation
operation of the appliance under the following conditions:
The appliance is supplied at rated voltage and operated continuously with the air inlet
adjusted to give a power input P after 20 s
m
Three minutes later, a final adjustment of the air inlet is made, if necessary.
P is calculated from the formula
m
P = 0,5 (P + P )
m f i
where
P is the power input in watts, after 3 min of operation with the air inlet unobstructed. Any
f
device that ensures a flow of air to cool the motor in the event of a blockage of the main
air inlet is allowed to operate;

– 10 – IEC 60335-2-2:2019 RLV © IEC 2019
P is the power input in watts, after a further 20 s of operation with the air inlet blocked. Any
i
device that is adjustable without the aid of a tool, and which ensures a flow of air to cool
the motor in the event of a blockage of a main air inlet, is rendered inoperative. If P has a
i
rapid non-linear decrease or cannot be measured due to the appliance suction motor
stopping before 20 s, the air inlet is gradually blocked to the extent that the motor stops
+5
after 20 s. In this case, P is the maximum value of power input in the last two
− 0
i
seconds before the motor shuts off.
If the appliance is marked with a rated voltage range, it is supplied at the mean value of the
range if the difference between the limits of the range does not exceed 10 % of the mean
value. If the difference exceeds 10 %, the supply voltage is the upper value of the range.
The measurements are made with the appliance fitted with a clean dust bag and filter, any
water collection container being empty. If the appliance is intended to be used only with a
hose, detachable nozzles and tubes are removed and the hose is laid out straight. If the
appliance is provided with a hose as an accessory, it is operated without the hose.
Rotating brushes and similar devices are in operation but not in contact with any surface.
Motorized cleaning heads are connected by means of the hose or tube and are in operation
but not in contact with any surface.
Appliance outlets for other accessories are loaded with a resistive load in accordance with the
marking.
Automatic battery-powered battery-operated cleaners are operated with a clean dust bag
or filter on the carpet defined in IEC 60312 meeting the construction specifications given in
Table 1 in IEC TS 62885-1:2018. A frame of 1,5 m by 1,5 m is used on the carpet to limit the
area of action. The air inlet is unobstructed.

Appliances having a liquid container shall be constructed so that spillage of liquid due to
overfilling, and due to overturning of appliances liable to be overturned in normal use, does
not affect their electrical insulation.
Compliance is checked by the following test.
The liquid container is filled with water to half the level indicated in the instructions. The
appliance is placed on a support inclined at an angle of 10° to the horizontal. A force of 180 N
is applied to the top of the appliance in the most unfavourable horizontal direction. If the
appliance overturns, it is considered to be liable to be overturned in normal use.
Appliances with 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 incorporating an appliance inlet are tested with or without an appropriate
connector in position, whichever is more unfavourable.
Liquid containers that are filled by hand are completely filled with water containing
approximately 1 % NaCl, and a further quantity, equal to 15 % of the capacity of the container
or 0,25 l, whichever is the greater, is poured in steadily over a period of 1 min.
Containers of hand-held appliances and other appliances liable to be overturned in normal
use are completely filled, the cover being closed. The appliance is then overturned and left in
that position for 5 min, unless it returns automatically to its normal position of use.
Nozzles and motorized cleaning heads of water-suction cleaning appliances are placed in
a container, the base of which is level with the surface supporting the appliance. The
container is filled with a detergent solution to a level of 5 mm above its base, this level being
maintained throughout the test. The solution consists of 20 g of NaCl and 1 ml of a solution of
28 % by mass of dodecyl sodium sulphate in each 8 l of water. The solution is to be stored in
a cool atmosphere and used within seven days of its preparation.
The appliance is operated until its liquid container is completely full and for a further 5 min.
NOTE 101 The solution is to be stored in a cool atmosphere and used within seven days of its preparation.
NOTE 102101 The chemical designation of dodecyl sodium sulphate is C H NaSO .

After each of these tests, the appliance shall withstand the electric strength test of 16.3.
Inspection shall show that there is no trace of liquid on insulation that could result in a
reduction of clearances or creepage distances below the values specified in Clause 29.
15.101 Motorized cleaning heads of water-suction cleaning appliances shall be resistant
to liquids that may come into contact with them.
Compliance is checked by the following tests.
The motorized cleaning head is subjected to an impact test as described in IEC 60068-2-75,
the value of the impact being 2 J. The motorized cleaning head is rigidly supported and
three blows are applied to every point of the enclosure that is likely to be weak.
It is then subjected to the test Free fall – Procedure 1 of IEC 60068-2-3231. It is dropped
4 000 times from a height of 100 mm onto a steel plate having a thickness of not less than
15 mm. It is dropped
– 1 000 times on its right side,

– 1 000 times on its left side,
– 1 000 times on its front face,
– 1 000 times on its cleaning surface.
The motorized cleaning head is then subjected to the test described in 14.2.7 of IEC 60529,
the water containing approximately 1 % NaCl.
The motorized cleaning head shall then withstand the electric strength test of 16.3, the
voltage being applied between the live parts and the solution. Inspection shall show that
there is no trace of saline solution on insulation that could result in a reduction of clearances
or creepage distances below the values specified in Clause 29.
NOTE The test is not carried out on motorized cleaning heads of class III construction
having a working voltage up to 24 V.
16 Leakage current and electric strength
This clause of Part 1 is applicable except as follows.
16.3 Addition:
Current-carrying hoses, except for their electrical connections, are immersed for 1 h in water
containing approximately 1 % NaCl, at a temperature of 20 °C ± 5 °C. While the hose is still
immersed, a voltage of 2 000 V is applied for 5 min between each conductor and all the other
conductors connected together. A voltage of 3 000 V is then applied for 1 min between all the
conductors and the saline solution.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
18 Endurance
This clause of Part 1 is not applicable.
19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.1 Addition:
The test of 19.7 is only carried out on motorized cleaning heads, vacuum cleaners with a
motorized brush or similar device, and separate fan motors of centrally-sited vacuum
cleaners.
Water-suction cleaning appliances having a valve are also subjected to the test of 19.101.
Appliances incorporating a booster setting that is not deactivated electronically are also
subjected to the test of 19.102.
Centrally-sited vacuum cleaners are also subjected to the tests of 19.103, and 19.104 if
applicable.

Vacuum cleaners that stop automatically when there is a blockage are also subject to the test
of 19.4.
19.4 Addition:
The appliance is tested under the conditions specified in Clause 11 with the inlet blocked.
Any control that is allowed to disconnect the suction motor during the P determination of
i
3.1.9 is short-circuited.
