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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC

4 General conditions for testing
4.1 Atmospheric conditions
Unless otherwise specified, 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: 91,3 kPa to 106,3 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.
For test procedures and measurements, which may be carried out at conditions other than
standard atmospheric conditions, the ambient temperature shall be maintained at (23 ± 5) °C.
NOTE Due to the influence of environmental conditions, variations in time, origin of test materials and proficiency
of the operator, most of the described test methods give more reliable results when applied for comparative testing
of a number of appliances at the same time, in the same laboratory and by the same operator.
4.2 Test equipment and materials
Equipment and materials for measurements (devices, test surfaces, stains, soils, etc.) to be
used in a test shall, prior to the test, be stored for at least 16 h at standard atmospheric
conditions in accordance with 4.1.
4.3 Voltage and frequency
Unless otherwise stated, measurements shall be carried out at rated voltage with a tolerance
of ±1 % and, if applicable, at rated frequency.
Wet hard floor cleaners designed for DC only shall be operated at DC. Wet hard floor
cleaners designed for both AC and DC shall be operated at AC. Wet hard floor cleaners not
marked with rated frequency shall be operated at either (50 ± 1) Hz or (60 ± 1) Hz with a total
harmonic distortion of < 3 %, as is common in the country of use.
For wet hard floor cleaners with a rated voltage range, measurements shall be carried out at
the mean value of the voltage range if the difference between the limits of the range does not
exceed 10 % of the mean value. If the difference exceeds 10 % of the mean value,
measurements shall be carried out at both the upper and lower limits of the voltage range.

© IEC/ASTM 2023
If the rated voltage differs from the nominal system voltage of the country concerned,
measurements carried out at rated voltage can give test results misleading for the consumer,
and additional measurements could be required. If the test voltage differs from the rated
voltage, this shall be reported.
Cordless wet hard floor cleaner chargers not marked with rated frequency shall be powered
at either (50 ± 1) Hz or (60 ± 1) Hz with a total harmonic distortion < 3 %, as is common in the
country of use. All charging should occur at the nominal system voltage of the country
concerned.
4.4 Running-in of wet hard floor cleaners
4.4.1 Mains-operated wet hard floor cleaner
Prior to the first trial, the appliance shall be kept operating while dispensing cleaning liquid,
steam, etc. for 30 min or until one tank of liquid, steam, etc. has been depleted. If the appliance
employs a pad, the pad shall be removed. If the appliance employs a vacuum, the run-in time
shall be 2 h, and the appliance shall be operated with unrestricted air flow during the run-in
period. It is not required to deplete more than one tank of liquid, steam, etc. during the 2 h run-
in period. If the appliance employs an active nozzle, the agitation device shall be running but
not in contact with the floor, unless otherwise specified by the manufacturer.
Prior to conducting any series of tests, the age, condition, and history of the product shall be
recorded.
4.4.2 Cordless wet hard floor cleaner
4.4.2.1 Preparation of cordless wet hard floor cleaner
Prior to the first trial (and following preparations in line with the manufacturer's instructions),
the appliance shall be fully charged in accordance with the manufacturer's instructions and
then kept operating while dispensing liquid, steam, etc. until fully discharged. The sequence
shall be repeated one more time with an interval of at least 30 min after each discharge. No
operation shall be carried out during this waiting time. If the appliance employs a pad, the pad
shall be removed. If the appliance employs a vacuum, the appliance shall be operated with
unrestricted air flow during the running-in sequence. If the appliance employs an active nozzle,
the agitation device shall be running but not in contact with the floor, unless otherwise specified
by the manufacturer. Depletion of no more than one tank of liquid, steam, etc. is required during
the running-in sequence.
Prior to conducting any series of tests, the age, condition, and history of the product shall be
recorded.
4.4.2.2 Preparation of the battery
Any unused Li-ion battery shall be fully charged and fully discharged once prior to conducting
the first trial on a cordless wet hard floor cleaner. All other battery chemistry/technology
types shall be fully charged and fully discharged three times prior to conducting the first trial
on a cordless wet hard floor cleaner. Fully charged and fully discharged conditions are
defined in 3.19 and 3.20, respectively.
NOTE It is understood that some cordless vacuums do not allow discharge below a certain energy level for battery
protection.
4.5 Equipment of the wet hard floor cleaner
If the wet hard floor cleaner is provided with a reusable pad(s) or brush that is intended to be
removable, it shall be cleaned and prepared according to the manufacturer's instructions prior
to each trial.

© IEC/ASTM 2023
Wet hard floor cleaners with receptacles to collect dirty cleaning solutions shall be cleaned
and/or maintained in accordance with relevant clauses and carried out according to the
manufacturer's instructions.
4.6 Operation of the wet hard floor cleaner
4.6.1 General
The grip of cleaners shall be held at a height of (800 ± 50) mm above the test surface. For
cleaning heads without pivoting connectors, it shall be ensured that the bottom of the cleaning
head be made parallel with the test surface by adjusting the handle height within the tolerances.
Any adjustment shall be reported.
During measurements where the agitation device of an active nozzle is not used as in normal
operation, the agitation device shall be running but not in contact with any surface.
The following wording regarding declaration and compliance shall also apply: "For declaration
and compliance purposes, related tests conducted on a hard floor shall be conducted with the
same wet hard floor cleaner setting configurations such as power, cleaning head and
cleaning head setting." Related tests are:

instructions for the test to be carried out. Any safety-related device shall be allowed to operate.
In the absence of unambiguous instructions within the manufacturer's instructions, the product
shall be tested with settings that are in accordance with any explicitly clear text, symbol or
pictogram that is identifiable on the product.
If, after following the above order of checks, the tester believes the device under test to be in
a configuration that is ambiguous, or that multiple configurations are possible with no way to
clearly determine which is the most suitable for a given task, then the manufacturer shall be
contacted for additional guidance.
Complete details of the settings used for each cleaning task, such as power, height settings
and the like shall be recorded in the test documentation.
If values for the performance of a product measured in accordance with this document are
published/declared (e.g. in the technical documentation), accurate and unambiguous details of
the settings that were used during the test procedure shall be provided.
NOTE Performance in other settings or combinations can differ from the results in the declaration settings; however,
this document does not address those results.
