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.

3 Terms, definitions and abbreviations

3.1 Terms and definitions
For the purposes of this document, the terms and definitions of IEC 60335-2-72 and the

following apply.
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 that have 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 it can be distinguished between main broom (main
cylindrical brush) and side broom. The main broom is located normally close to the hopper. The bristles of the main
broom normally are 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 Abbreviations
For the purpose of this document, the following abbreviations apply.
GVW Gross vehicle weight
FOPS Falling-object protective structures
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 (in accordance with ISO 554):
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 with 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,

except as noted elsewhere in this standard. Throughout the measurements, the same type of

pad/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 done 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.

– 10 – IEC 62826:2014 © IEC 2014

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.

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 like 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
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, 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, which weighs 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 case of scrubbers or combined machines), and
– 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 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 measurement. For the purpose
of this measurement this is acceptable.
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.

– 12 – IEC 62826:2014 © IEC 2014

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 propelling forward.

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/brush contact area.
The contact area can be visualized (and subsequently measured) by letting the pad/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:
2 2
A = π ⋅ (r −r )
o
i
where
r is the outer radius of the contact area (total pad/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 Due 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 Rotating speed of pads, brushes and brooms

11.1 General
The rotating 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 rotating speed attainable without cleaning attachment in contact with the floor. The
nominal speed of the output shaft of the pad/brush/broom motor gear box combination can be
taken as indication for the maximum rotating speed.
NOTE It may 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 rotating speed attainable while operation cleaning attachment under maximum
scrub deck down force (see Clause 9).

11.4 Reporting
The rotating 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 according to IEC 60335-2-72.
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 straight forward 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 – IEC 62826:2014 © IEC 2014

14.2 Sound pressure Level
The overall A-weighted emission sound pressure level, at the operator 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.
14.4 Reporting
The values and the uncertainties are reported in dB(A).
15 Vibration

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.
