Part 2-68: Particular requirements for spray
extraction machines, for commercial use

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.

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 2-68: Particular requirements for spray
extraction machines, for commercial use

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrical portable, non-self-propelled
motor-operated spray extraction machines with or without attachments and with or without
electrical heating elements, intended for commercial indoor use.
NOTE 101 This standard applies to machines for commercial use. The following list, although not
comprehensive, gives an indication of locations that are included in the scope:
– public use areas such as hotels, schools, hospitals;
– industrial locations, for example factories and manufacturing shops;
– retail outlets, for example shops and supermarkets;
– business premises, for example offices and banks;
– rental services for those machines;
– all uses other than normal housekeeping purposes.
They are not equipped with a traction drive. The following power systems are covered:
– mains powered motors up to a rated voltage of 250 V for single-phase appliances and
480 V for other appliances,
– battery powered motors.
This standard applies to machines in which the pressure of the employed cleaning agent
does not exceed 2,5 MPa, and in which the product of the pressure (in MPa) and the flow of
cleaning agent (in litres per minute) does not exceed 100, and in which the temperature of
the cleaning agent at the spray nozzle outlet does not exceed 85 °C.
This standard does not apply to
– vacuum cleaners and water-suction cleaning appliances for household use
(IEC 60335-2-2);
– floor treatment machines for commercial use (IEC 60335-2-67, IEC 60335-2-72);
– wet and dry vacuum cleaners, including power brush, for commercial use
(IEC 60335-2-69);
– hand-held and transportable motor-operated electric tools (IEC 60745 series, IEC 61029
series).
– machines designed for use in corrosive or explosive environments (dust, vapour or gas);
– machines designed for picking up hazardous dusts (as defined in IEC 60335-2-69),
inflammable substances, or glowing particles;
– machines designed to handle hazardous solvents, such as flammable or explosive liquids;
NOTE 102 Attention is drawn to the fact that in many countries, additional requirements on the safe use of the
equipment covered can be specified by the national health authorities, the national authorities responsible for the
protection of labour, the national water supply authorities and similar authorities.

3 Terms and definitions
This clause of Part 1 is applicable except as follows.
3.1.9 Replacement:
normal operation
conditions under which the machine is operated in normal use, specified as follows:
the machine is operated with the spray extraction pump with the nozzle giving the highest
load, the vacuum motor, the device for agitating the carpet pile (if any), the cleaning agent
heater (if any) and the soiled water discharge pump (if any) all in use. Any marking of short
time intermittent operation of the pumps is observed.
The normal operation P of the vacuum motor is obtained at the following power input:
m
P = 0,5 (P + P )
m f i
where
is the input, in watts, when the machine has been operated for 3 min, fitted with the
P
f
nozzle and hose giving the highest input;
is the input, in watts, when the machine has been operated for 20 s with the nozzle
P
i
sealed, immediately following the 3-minute-period with the nozzle open. Any valve or
similar device used to ensure a flow of air to cool the motor in the event of a blockage
of a main air inlet is rendered ineffective.
P and P are measured with the supply voltage adjusted to rated voltage, or to a voltage
f i
equal to the mean value of the rated voltage range if the difference between the limits of the
rated voltage range does not exceed 10 % of the mean value of the range. If the difference
between the limits of the rated voltage range exceeds 10 % of the mean value, the tests are
carried out with the supply voltage set to the upper limit of the range.
The hose is laid out straight. If the machine is provided with a hose as an optional accessory,
it is operated without the hose.
Electrically driven devices for agitating the carpet, if any, are in operation but are not in
contact with the floor or any other surface or with the means used to seal the air inlet.
The adjustment of the air inlet is not altered when it is specified that the machine is operated
under normal load, irrespective of the supply voltages specified in the test. Where optional
filtration systems are supplied with the spray extraction machine, the filtration system giving
the least air resistance (maximum flow) is fitted.

60335-2-68 © IEC:2012 – 9 –
The normal load is equal to the mean load P for the electrically driven agitating device such
r
as a motor driven brush is determined in accordance with the following:
– the agitating device operates on a carpet as specified in IEC 60312-1;
– the mean load P is determined when using the device in the following way:
r
After setting the device, the device is moved twice over a distance of 5 m in the direction
giving the highest load;
– the motor responsible for the airflow operates under the same conditions as determining
P , i. e. no airflow restrictions, and measurements are taken after 3 min;
f
– the device is adjusted to the carpet pile height;
– it is necessary to move the agitating device slowly across the carpet to avoid carpet
damage.
Soiled water discharge pumps, if applicable, are operated as follows.
The pump delivers a continuous flow of water without any soiled water discharge hose
attached to the soiled water outlet of the machines unless the discharge hose is permanently
attached to the machine. The vacuum motor works during the test, unless an interlock device
is provided to prevent combined operation of both motors.
Socket-outlets for accessories are loaded with a resistive load in accordance with the
marking.
