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: 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.
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 will 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
© IEC/ASTM 2018
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.
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.
4.4 Running-in of wet hard floor cleaners
Prior to the first test of a new wet hard floor cleaner, the appliance shall be kept operating
for at least 30 min while dispensing cleaning liquid, steam, etc. to ensure adequate running-in.
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. If the appliance employs an active nozzle, the agitation device shall
be running but not in contact with the floor.
Prior to conducting any series of tests, the age, condition, and history of the product shall be
recorded.
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 removable
without the aid of tools, it shall be cleaned and prepared according to the manufacturer's
instructions prior to each measurement.
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
The wet hard floor cleaner shall be used and adjusted in accordance with the manufacturer's
instructions for normal operation for the test to be carried out. Height adjustment controls (if
any) for the cleaning head shall be set as appropriate and the position noted. Any
safety-related device shall be allowed to operate.
For a wet hard floor cleaner with more than one cleaning head, the cleaning head
recommended by the manufacturer in the user instructions for cleaning tasks corresponding to
the cleaning tests described in 5.1 to 5.5 shall be used. If no instructions are provided,
contact the manufacturer or the wet hard floor cleaner shall be tested with the cleaning
head with the largest head width for the appropriate purpose. The cleaning head used for
each test shall be reported.
For a cleaning head with more than one setting, the setting recommended by the
manufacturer in the user manual for cleaning tasks corresponding with the cleaning tests
described in 5.1 to 5.5 shall be used. If no instructions are provided in the user manual,
contact the manufacturer to determine the correct setting. If the manufacturer cannot provide
the correct setting, the cleaning head shall be tested in its default delivery setting. The
setting used for each test shall be reported.
Any electrical controls shall be set for maximum continuous operation and air flow. Unless the
manufacturer's instruction states otherwise, any manually operated air by-pass openings for
reduction of the suction power shall be closed, and if open, it shall be reported.
– 10 – IEC/ASTM 62885-6:2018
© IEC/ASTM 2018
4.7 Conditioning prior to each test
4.7.1 General
If the wet hard floor cleaner is unused and de-energized for more than 1 h, then the wet
hard floor cleaner shall be kept running for at least 10 min under the provisions given in 4.4
to allow it to stabilize.
4.7.2 Preparations specific to steam cleaners
Follow the manufacturer's instructions to prepare the steam cleaner for use. When the steam
cleaner is ready for operation (after the heating-up phase), produce steam for 15 s to remove
any air and/or condensed water from the steam conduits in the appliance to ensure proper
priming of the system. Prior to any test, a clean pad is to be installed on the cleaning head,
which has been washed and thoroughly dried in accordance with the manufacturer's
instructions. This step is necessary to ensure no foreign substances on a new or used pad will
affect the test results. Place the cleaning head on a clean floor surface and produce steam
for 15 s to moisten the pad.
4.7.3 Preparations for other wet hard floor cleaners
Follow the manufacturer's instructions for preparing and priming the product for floor cleaning
use.
4.8 Mechanical operator
In order to achieve reliable results, certain tests require the cleaning head to be moved at
uniform speed over the test area and without exerting an additional force pressing the
cleaning head against the test surface.
It is recommended to simulate the handling of the wet hard floor cleaner by using a
mechanical operator such as that described in 7.3.1. The handle of the cleaner shall be
attached to the linear drive so that its centre pivots at a height of (800 ± 50) mm above the
test surface. For nozzles 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.
The linear drive may be motorized or operated by hand. The method of operation shall be
reported.
4.9 Number of samples
All measurements of performance shall be carried out on the same sample(s) of the wet hard
floor cleaner.
For increased confidence in the test results, a minimum of three samples of a wet hard floor
cleaner should be tested.
Tests carried out to simulate stresses that a wet hard floor cleaner can be exposed to during
normal use, possibly causing impairment of the cleaner's performance, can require additional
samples of replaceable parts. Such tests shall be carried out at the end of the test
programme.

5 Wet hard floor cleaning tests
5.1 Cleaning efficiency of hard flat floors – Purpose
5.1.1 General
The purpose of this test is to measure how quickly the appliance can remove dried stains of
certain soils from ceramic or porcelain tiles. Porcelain tiles are to be stained with
representative soils that are typically found in household kitchens. After a drying period, the
tiles are to be cleaned with the appliance in a defined way until the stains are not visible. The
measured value is the number of necessary cleaning strokes to remove each stain.
5.1.2 Apparatus
Floor tiles: glazed ceramic or porcelain tiles meeting the requirements of 7.2.1.
Tile floor cleaning fixture: a portable floor surface on which three replaceable porcelain tiles
can be fixed in a single line adjacent to each other. The fixture shall include a guide in the
longitudinal direction for guiding the floor cleaning head of the appliance to be tested such
that the cleaning head can only make a longitudinal motion during the cleaning procedure.
The guide can be adjusted to the specific width of the cleaning head of the appliance to be
tested (see Figure 12).
Stroke Pacing Device: a light bar or other similar timing device that can be set to the desired
cleaning stroke length and a cleaning stroke speed of 0,2 m/s is recommended (Figure 12). In
lieu of a pace setting device, a stopwatch may be used to time the strokes to ensure a stroke
speed of 0,2 m/s.
Adjustable pipette: 100 to 1 000 µl range for applying liquid stains (see Figure 13).
Stain application template (type A, see 7.3.4): soil stain templates to mark the points on the
tiles that are to be stained with liquid or pasty soils in accordance with 7.3.4.
Spoon and spatula: for spreading the pasty soils (see Figure 1).
Figure 1 – Photo of spoon and spatula
Digital video camera (optional): to take photographs of the stained tiles before and after the
cleaning test, and to video record the cleaning procedure for confirming number of strokes
required to remove stains and soils.
Electronic scale: for weighing tiles, having a resolution of 0,01 g with a minimum
measurement range of 3 000 g (see Figure 2).
– 12 – IEC/ASTM 62885-6:2018
© IEC/ASTM 2018
Minimum measurement capability: (3 000 ± 0,01) g
Figure 2 – Electronic scale for weighing of tiles
Tile drying rack: large enough to hold 20 to 50 tiles at a time is recommended. The drying
rack shelves should be flat and level to prevent flowing of the liquid stains while drying
(see Figure 3).
Figure 3 – Tile drying rack for preparing and drying soil stains
5.1.3 Materials
Test soils: food soils in accordance with 7.2.2.
Bleach and cotton cloths: for cleaning floor tiles after each test run. The recommended
dilution ratio is 15 g of bleach to 1 l of water.
© IEC/ASTM 2018
Demineralized water: demineralized water in accordance with 7.2.3 shall be used in all wet
hard floor cleaners for mixing cleaning solution or for cleaning in steam appliances. The use
of local tap water of unknown quality and hardness is not recommended unless otherwise
stipulated by the manufacturer.
5.1.4 Sampling and test trials
Three samples of a given product model, selected at random, should be evaluated to estimate
the average cleaning score for the cleaning efficiency of hard flat floors. Three test trials shall
be performed with each product sample for each soil stain.
5.1.5 Method
5.1.5.1 Floor tile cleaning and preparation
New tiles, and used tiles after a cleaning test cycle, shall be thoroughly cleaned with bleach
water (ratio: 15 ml bleach per 1 l of water). Afterwards, rinse with clean water and wipe with a
clean cotton cloth until dry. The tiles shall be completely dry before applying a soil.
5.1.5.2 Floor tile soiling preparation
The tile staining procedure depends on the consistency of the soil to be used (liquid or pasty).
See 7.2.2 for the composition of each soil to be applied to the tile, and the tools to be used.
Tiles and soil stains are to be prepared and stored under standard atmospheric conditions in
accordance with 4.1.
Staining with liquid soils:
1) Prepare the porcelain tiles 23 h to 24 h in advance of the cleaning times.
2) Preparing the coffee mix: add 4 g of soluble coffee, 10 g of cream for coffee, and 5 g of
sugar in 200 ml of warm water (50 °C) and stir the mix with a spoon for 1 min.
3) Place a clean tile in accordance with 5.1.5.1 on a flat surface.
4) Place a stain application template (type A, see 7.3.4) on the middle of the tile.
5) Make a small mark with a pencil on the surface of the tile at the centre of each of the five
holes of the template. Afterwards, remove the template from the tile (see Figure 4).

Figure 4 – Marking of tile
6) Place the tile on the drying rack prior to soiling as the tile shall not be moved after
applying the liquid soil.
7) Adjust the pipette to the defined volume of 300 µl. Draw up the liquid coffee soil with the
pipette.
8) Bring the tip of the pipette to approximately 5 mm directly above one of the pencil marks
on the tile. While holding the pipette perpendicularly to the surface of the tile, press the

9) Repeat steps 7) and 8) for the rest of the marks.
10) The width of every stain shall not be greater than 35 mm.
11) After the staining process (during the drying period), the tiles shall not be moved.
Staining with pasty soils:
1) Prepare the porcelain tiles 23 h to 24 h in advance of the cleaning times.
2) Preparing remoulade: mix 50 g of remoulade with 1 g of colourant in a container, stirring it
well with a spoon for 1 min until the mixture is homogenous.
3) Preparing mustard: shake the mustard container for at least 30 s to ensure a homogenous
mix of ingredients that can have separated. No additional preparation is required.
4) Place a clean tile in accordance with 5.1.5.1 on a flat surface.
5) Place a stain application template (type A, see 7.3.4) on the middle of the tile.
6) Apply the soil on the surface within the area of each hole of the template, and spread it
with a spoon. Each hole is to be covered completely with soil (see Figure 6).

9) Remove the template after the drying process.
5.1.5.3 Soil drying
Allow the soil stains to dry on the tiles under standard atmospheric conditions in accordance
with 4.1 for at least 22 h, but not longer than 24 h, prior to performing the cleaning process.
Cleaning tests should be performed within 1 h after the drying period to reduce variability in
the cleaning results.
5.1.5.4 Cleaning procedure
Three test trials are required for determining the average cleaning efficiency of a given
appliance to clean each type of soil stain.
Prepare the test unit(s) in accordance with 4.7.
1) Steam cleaners: fill the product with demineralized water (unless otherwise stipulated by
the manufacturer). For one-tank systems (i.e. non-refillable appliances while operating),
the boiler is to be filled up to three-quarters of the manufacturer's recommended capacity.
After three cleaning processes, the appliance shall be allowed to cool down, in
accordance with the manufacturer's instructions, so that it can be filled again up to three-
quarters of the manufacturer's recommended capacity, that is if further tests are to be
carried out. This step is required to ensure that similar conditions prevail in the boiler
during the tests, and to guarantee the reproducibility of the test method.
2) For non-steam cleaners: follow the manufacturer's instructions for setup and detergent
mix (if employed) for preparing the product for use. Demineralized water shall be used for
all detergent mixes.

3) Attachments: Use only those attachments, pads, or accessories that are intended to be
used with the type of floor employed in this test method.
Apply the rated voltage to the steam product under test.
Place a stained tile on the cleaning fixture between two clean tiles in a position so that the
two rows of stains are perpendicular to the longest edge of the fixture.
Priming of cleaning appliances:
1) Steam cleaners: when the steam product is ready for operation (after the heating-up-
phase), produce steam for 15 s to remove the air and/or condensed water from the steam
conduits in the appliance. Next, fasten the pad on the steam cleaning appliance's floor-
cleaning head, place it on a separate clean tile, and produce steam for 15 s to moisten the
pad. Before any testing is performed, the pads are to be washed and dried according to
the manufacturer's specifications to ensure that no foreign substances affect the cleaning
results.
2) Non-steam cleaners: follow the manufacturer's instructions for preparing or priming the
product for floor cleaning use.
Cleaning strokes:
1) Immediately after the priming sequence, place the cleaner's floor cleaning head at the
starting position of the porcelain tile, floor cleaning fixture. The front edge of the cleaning
head is to be placed approximately 470 mm before the centre of the tile containing the soil
stain. The middle of the cleaning head should be aligned to the stain in the centre of the
tile (see Figure 8)
Figure 8 – Cleaning stroke starting position
2) Ensuring that no downward force is applied to the product's cleaning head, execute a
forward cleaning stroke until the front of the product's floor cleaning head reaches the end
location. The front of the edge of the product should travel approximately 330 mm past the
centre of the tile containing the soil stains as shown in Figure 9. (Note: the definition of a
single cleaning stroke is a one-directional pass of the floor cleaning head across the tile to
be cleaned.)

Figure 9 – End position after first stroke
3) Next, execute a return cleaning stroke until the product's floor cleaning head reaches the
starting position, again ensuring that no downward force is applied to the machine
cleaning head.
4) Each cleaning stroke is to be performed at a rate of 0,2 m/s by following the stroke pacing
device.
5) During the cleaning strokes, ensure that the floor cleaning head has a flat contact with the
floor surface. The guide of the floor tile cleaning fixture is employed to ensure that the
floor cleaning head travels a straight path during the cleaning strokes.
6) Continue executing cleaning strokes until the stain is no longer visible from the operator's
position, or until a total of 26 cleaning strokes have been reached. The stain shall be
visibly removed from all tiles, not just the soiled tile. Any transfer of soil to the adjacent
(unsoiled) tiles shall also be removed in the determination of total cleaning strokes. The
cleaning process may be recorded with a video camera.
7) Perform 2 additional test trials resulting in a total of 3 separate tiles cleaned for each stain
type.
5.1.5.5 Determination and reporting of cleaning efficiency
For each test trial, record the number of strokes required to clean each soil stain. If a video
recording was taken of the cleaning process, it may be used to confirm the number of
cleaning strokes recorded by
