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 62885-9 has been prepared by subcommittee SC 59F: Surface
cleaning appliances, of IEC technical committee TC 59: Performance of household and similar
electrical appliances.

3.1.1
pad
cleaning tool of round, oval or other shape, attached to a scrubber in order to clean the
surface (floor) by abrasive rotations
Note 1 to entry: It consists of a coarse or fine synthetic membrane. The abrasiveness can be recognized by the
colour. The structure (open/closed) determines the suitability for high/low speeds.
3.1.2
brush
cleaning tool of round, oval or other shape, attached to a scrubber in order to clean the
surface (floor) by abrasive rotations
Note 1 to entry: It consists of natural or synthetic fibres of different kinds of hardness fixed in a holder. The
hardness is subject to the tasks to be executed, such as scrubbing, polishing or shampooing.
3.1.3
broom
cleaning tool of round shape, attached to a sweeper in order to clean the surface (floor)
Note 1 to entry: Regarding the automatic cleaning brooms, distinction can be made between the main broom
(main cylindrical brush) and the side broom. The main broom is located normally close to the hopper. The bristles
of the main broom are normally arranged as straight, spiral or spiral-vee lines of bristles. Thereby they generate
the necessary skidding and there is room enough for bigger particles between the lines of bristles. The function of
the side broom is to sweep away dirt from corners and borders towards the course of the main broom.
3.2 Abbreviated terms
FOPS falling-object protective structures
GVW gross vehicle weight
ROPS roll over protection system
4 General conditions for testing
4.1 Atmospheric conditions
Where required, the test procedures and measurements shall be carried out under the
following conditions:
Standard atmosphere: 23/50
Temperature: (23 ± 2) °C
Relative humidity: (50 ± 5) %
Air pressure: 86 kPa to 106 kPa
Temperature and humidity conditions within the specified ranges are required for good
repeatability and reproducibility. Care should be taken to avoid changes during a test.
4.2 Machine loading
The machine is loaded for testing to its GVW, as specified in 8.1, unless otherwise stated.
4.3 Machine set-up
Machine settings shall be as described under normal operation as defined in
IEC 60335-2-72:2016, except as noted elsewhere in this document. Throughout the
measurements, the same type of pad or brush has to be used.

5 Working path width
5.1 Working scrubbing path width
The path the machine cleans, based solely on the width of the brushes or pads. This is the
width that is exposed to the full cleaning process, to indicate the effective cleaning width of
the machine, not the outside physical width of the machine.
5.2 Total pad/brush width
The nominal width of the cleaning pads or brushes, not taking into account overlap of the
pads or brushes. The purpose of this value is to communicate to the end user the size of the
pads or brushes that are to be used with the machine.
NOTE This value can be given as follows (example): W = 300 mm for a single pad, or W = 2 × 300 mm for
Pad Pad
two pads.
5.3 Maximum squeegee width
The path that is covered by the squeegee while operating in a straight line.
5.4 Minimum working sweeping path width
The path the machine sweeps based solely on the nominal width of the main broom, to
indicate the effective sweeping width of the machine, not the outside physical width of the
machine.
5.5 Maximum working sweeping path width
The path the machine sweeps based solely on the nominal width of the main broom and the
side brooms. It is intended to indicate the effective sweeping width of the machine, not the
outside physical width of the machine.
5.6 Measurement method
The working path width is the measured width of the floor that is swept or wetted and
scrubbed while cleaning in a straight line. All measurements shall be carried out with the
machine in the minimum down force setting.
NOTE 1 The more down force that is applied to brushes, the larger the overall diameter of the contact circle with
the floor. Testing at the minimum setting will minimise this effect.
NOTE 2 The maximum working path width can be visually detected and measured by letting the
brooms/pads/brushes work on a wax coated floor or a soiled floor (e.g. with sand for sweepers and paint for
scrubbers).
5.7 Reporting
The values shall be given for a standard machine, and the widths for machines fitted with
options shall be noted separately. The values are reported in mm.
6 Minimum aisle turn-around width
6.1 General
The minimum aisle width the machine can turn around in without reversing is an indication of
the manoeuvrability of the machine during operation.

– 10 – IEC 62885-9:2019 © IEC 2019
6.2 Measurement method
Aisle turn-around width is measured as the minimum distance between two parallel vertical
planes that allows the machine to turn 180°, during normal operation, without contacting
either of the planes. The planes used shall be higher than the highest elements of the
machine under test. The test has to be carried out in both directions.
Flexible components such as squeegees or brushes are allowed to contact the planes.
6.3 Reporting
The value is reported in mm. If the test results for both directions are different, then both
figures shall be reported.
7 Machine transport width
7.1 General
The minimum width the machine can pass through, to indicate the manoeuvrability of the
machine during transport, not the effective cleaning width of the machine.
7.2 Measurement method
Machine width is measured as the minimum distance between two parallel vertical planes that
allows the machine to pass between the planes, while moving in a straight line. Any
removable machine part taken off as indicated in the operating manual for this measurement
shall be reported with the result.
7.3 Reporting
The value is reported in mm for each machine configuration.
8 Weight
8.1 Gross vehicle weight (GVW) taken from IEC 60335-2-72:2016
The maximum allowable fully laden weight of the machine and its payload, as ready for use,
to indicate the maximum weight of the machine.
The GVW includes, if applicable, full clean water tanks, empty dirty water tanks (half full for
recycling systems), hopper and dust bags loaded at rated weight capacity, the largest
recommended batteries, all options such as cords, hoses, wands, cleaning agents, brooms,
brushes, air conditioning and cabins. For ride-on machines, the GVW shall include a standard
operator weighing 75 kg.
NOTE 1 A sweeper with a full hopper is not ready for use, but is the heaviest configuration for a sweeper.
NOTE 2 GVW could be apportioned into front and rear axle weight.
8.2 Empty weight
The empty weight of the operational machine, to indicate the maximum weight of the machine
without options and batteries.
NOTE This value along with the weight of the container and packaging can be used to calculate the shipping
weight.
The empty weight of the operational machine shall exclude

– traction batteries,
– options (e.g. driver cabin, FOPS, ROPS, second and third side broom, front mounted
sweeping attachment for scrubbers),
– waste water,
– cleaning detergent,
– swept debris,
– fresh water (in the case of scrubbers or combined machines), and
– the operator’s weight.
The weight of options and batteries can be noted separately.
8.3 Transportation weight
The transportation weight of the machine, in kilograms, which includes the batteries but
excludes options (e.g. driver cabin, FOPS, second and third side broom, front-mounted
sweeping attachment for scrubbers), fresh water (in the case of scrubbers or combined
machines), and the weight of a standard operator (75 kg).
8.4 Reporting
The values are reported in kg. The actual mass may vary by ±5 %.
9 Maximum scrub deck down force
9.1 General
The maximum down-force on the floor is intended to be an indication of the maximum
scrubbing force that can be generated by the machine in normal operation, without
overloading motors or circuit protection devices.
9.2 Measurement method
Maximum scrub deck down force is measured as the reactive force while operating the
machine in a stationary position, with the deck on a smooth stainless-steel surface (not more
than 1,5 mm above or under the ground plane).
NOTE Squeegees that are mounted on the scrubbing unit will affect the result of the measurement. This is
acceptable for the purpose of this measurement.
9.3 Reporting
The reported value in N is the recorded maximum force that the measurement does not drop
below during a 15 s measurement period, using clean tap water. For a cylindrical deck, the
manufacturer shall specify the type of brush material to be used. For a disc deck, a typical
medium grade pad shall be used.
The brush or pad material type and the machine scrub setting shall be stated in the report.
If the machine design is such that the down force varies as the power input changes, the
minimum value during the 15 s measurement period shall be recorded. All side skirts that
contact the stainless-steel plate during the test shall be positioned, or fixed, so that they are
capable of supporting as much weight as they would if the machine were propelled forward.

– 12 – IEC 62885-9:2019 © IEC 2019
10 Maximum scrub deck down pressure
10.1 General
The scrub deck down pressure is calculated as the force per pad/brush contact area.
10.2 Determination method
The scrub deck down pressure is calculated by dividing the scrub deck down force
(see Clause 9) by the complete pad or brush contact area.
The contact area can be visualized (and subsequently measured) by letting the pad or brush
work on a wax-coated floor or a soiled (painted) floor. For cylindrical brushes or pads, the
area inside of the rectangular pattern that the pad/brush visualized on the floor is relevant.
Alternatively, the contact area of disc brushes or pads may be calculated as follows:
A=π⋅ rr−
( oi )
where
r is the outer radius of the contact area (total pad or brush width, see 5.2);
o
r is the inner radius of the contact area, i.e. the internal area without bristles, if applicable.
i
For orbiting scrub systems, the contact area shall be calculated.
NOTE Owing to the orbiting system, a visualization as previously described would enlarge the measured area
incorrectly.
10.3 Reporting
Maximum scrub deck down pressure is reported in N/cm . The type of pad or brush should be
noted along with the machine scrub setting used during this measurement.
11 Rotational speed of pads, brushes and brooms
11.1 General
The rotational speed indicates the number of revolutions per minute that the cleaning
attachment will attain at the stated load.
11.2 Measurement method – unloaded operation
Maximum rotational speed attainable without the cleaning attachment in contact with the floor.
The nominal speed of the output shaft of the pad/brush/broom motor gearbox combination can
be taken as indication for the maximum rotational speed.
NOTE It can be impossible to measure this value because machine controls switch off the drive of the unloaded
cleaning attachment.
11.3 Measurement method – loaded operation
Maximum rotational speed attainable while operating the cleaning attachment under maximum
scrub deck down force (see Clause 9).

11.4 Reporting
The rotational speed is reported in r/min.
12 Maximum floor load and wheel contact pressure
12.1 General
The maximum pressure exerted onto a floor surface by any wheel or caster on the machine
during expected operation or transport mode.
These parameters are intended to indicate the suitability of the machine for specific floor
surfaces. The values can be compared against the static load limit rating of the floor surface.
12.2 Measurement method
The maximum floor load shall be measured in accordance with Annex A on concrete precast
paving slabs that conform to IEC 60335-2-72:2016.
12.3 Reporting
The value is reported in accordance with Annex A.
13 Speed
13.1 Maximum transport mode speed (power-driven machines)
The transport speed of the machine, moving in a straightforward direction, on a flat smooth
surface. This parameter is intended to indicate the maximum transport speed of the machine,
with no other machine functions operating.
13.2 Maximum working mode speed
The working speed, as defined by the manufacturer, at which the machine is travelling in a
straight, forward direction, on a straight, flat, smooth concrete surface. This parameter is
intended to indicate the recommended maximum working speed of the machine, with all floor
cleaning functions of the machine operating simultaneously.
13.3 Measurement method
Transport mode speed is measured after acceleration to the maximum speed is achieved.
Working mode speed is measured after acceleration to the working speed is achieved.
13.4 Reporting
The values are reported in km/h.
14 Sound
14.1 Sound power level
The overall A-weighted emission sound power level of the machine, to indicate of the total
sound power emitted by the machine.

14.2 Sound pressure Level
The overall A-weighted emission sound pressure level, at the operator's position, to indicate
the noise that the operator is exposed to during the normal operation of the machine.
14.3 Measurement method
Measurement in accordance with measurement of emission of acoustical noise as given in
IEC 60335-2-72:2016.
14.4 Reporting
The values and the uncertainties are reported in dB(A).
15 Vibration
15.1 Hand-arm system vibration total value
For all machines, the vibration total value to which the hand-arm system is subjected shall be
measured.
15.2 Whole-body vibration total value
For ride-on machines and walk-behind machines with a sulky, the highest root mean square
value of weighted acceleration to which the whole body is subjected shall be measured.
15.3 Measurement method
Measurement in accordance with measurement of emission of vibration as given in
IEC 60335-2-72:2016.
15.4 Reporting
The values including their uncertainties are reported in m/s .
16 Solution flow rate
16.1 General
The amount of solution (water only) sprayed or dispensed to the brushes at each flow setting,
to indicate the average continuous solution flow rate during normal operation.
16.2 Measurement method
Solution flow rate shall be measured with the solution tank at half of its full useful capacity, as
determined in Clause 18.
NOTE 1 The solution flow rate can vary depending upon head pressure.
NOTE 2 The flow rate can be measured and calculated by various methods. One method is to weigh the machine
at the start and end of a defined time period, calculate the weight differential, divide this value by the weight of
water to determine the volume of water, and then divide the volume by the test time to get the flow rate. Another
method is to use a flow meter to take this measurement.
16.3 Reporting
The value is reported in l/min at each flow or scrub setting. If the flow rate is variable, the
maximum value shall be reported along with the available range, for example 0 l/min to 10
l/min.
17 Rated hopper volume capacity
17.1 General
The maximum functional volume of debris that a hopper may hold in normal operation, to
indicate the useful volume of the respective hopper. This value is the sum of the struck
capacity of the hopper (quantity of fluid the hopper could hold) and the heaped capacity
(quantity of dry debris that could be piled above the top of the struck capacity).
