4 Test equipment for dry cleaning
4.1 Mechanical operator
4.1.1 General
The construction principle of a mechanical operator is indicated in Figure 1. It consists of a rigid
support with a linear drive capable of carrying out single and double strokes over the test
surface (carpet or hard floor), and is kept in position by hold-downs. As shown in Figure 1, the
equipment can be adapted to tests of motion resistance as described in IEC 62885-2:2021 [2]
(motion resistance), allowing its wooden plate a sufficient freedom of movement in the direction
of the strokes.
NOTE The linear drive can be motorized or operated by hand.

Figure 1 – Mechanical operator for tests of dust or debris removal from carpets or hard
floors and of motion resistance
The spur racks, which suggest a way to bring about the vibratory action to the dust spreader
depicted in Figure 1, have no function in the motion resistance test.
4.1.2 Stroke length and test area
Unless otherwise specified within the particular product standard, the length of the test area is
(700 ± 5) mm and the width of the test area is equal to the cleaning head width.
A length of at least 200 mm shall be added before the beginning of the test area and at least
300 mm after the end of the test area in order to allow acceleration and deceleration of the
cleaning head.
Thus, the stroke length is at least 1 200 mm for the given test length of 700 mm. The centre
line of the front edge of the cleaning head is aligned to the centre line of the beginning of the
acceleration area at the commencement of the stroke, allowing the distance of 200 mm to be
used for acceleration. The cleaning head shall reach the end of the stroke when the rear edge
of the active depth of the cleaning head is at least 200 mm past the end of the test area, thus
allowing a suitable distance for deceleration. The return stroke is carried out in the same
manner until the front edge of the cleaning head is once again lined up with the beginning of
the acceleration length in front of the test area.
4.1.3 Stroke speed
Unless otherwise specified within the particular product standard, the active depth of the
cleaning head shall move at uniform stroke speed (0,50 ± 0,02) m/s and in a straight line over
the test area.
Two hold-downs in accordance with 4.1.5 act as guides to keep the cleaning head in a straight
line as it is moved over the test area and to ensure an undisturbed flow.
Dry vacuum cleaners equipped with a self-drive device shall be operated at the prescribed
stroke speed of (0,5 ± 0,02) m/s, if possible. Otherwise, the stroke speed will be determined by
the dry vacuum cleaner.
4.1.4 Handle height
Unless otherwise specified in the particular product standard, the grip of cleaners with suction
hose or the handle of other cleaners pivot at a height of (800 ± 50) mm above the test surface.
Any telescopic tubes or sticks shall be extended to maximum length. 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. If this is not possible,
the length of a telescopic tube or stick can be adjusted. Any adjustment shall be reported.
4.1.5 Hold-downs and guides
The two hold-downs shall be at least 1,4 m × 0,05 m × 0,05 m in dimension and weigh 10 kg/1,4
m each. They shall be designed in such a way so as not to obstruct the air flow at the sides of
the cleaning head (see Figure 2). The edges of the hold-downs adjacent to the cleaning head
should be treated to reduce friction. Pegs can be omitted within the test length.
Low-friction adhesive tape can be used to reduce friction.
The hold-downs shall be placed on either side of the test area with a clearance of not more
than 2 mm on both sides of the cleaning head.
Dimensions in millimetres
Figure 2 – Carpet hold-downs and guides
4.1.6 Mechanical dust spreader (optional)
The device consists of a tray extending across the width of the test area and mounted on a
trolley, which can be moved along the length of the test area without impinging upon it. When
the trolley is moved back and forth over the test area, a vibratory action causes the test dust,
which has been placed evenly along the tray, to emerge from a line of suitably sized holes along
the base of the tray, equally spaced and sufficient in number to cover the test area uniformly
with test dust.
The vibratory action can be brought about by an incorporated vibrator or by the trolley running
on spur racks as indicated in Figure 3.

Figure 3 – Dust spreader and roller for embedding dust into carpets
4.1.7 Test plate with crevice
The equipment consists of a wood panel provided with a removable insert of aluminium having
a (3 ± 0,05) mm wide and (10 ± 0,05) mm deep smooth crevice (see Figure 4).
The crevice insert shall lie at the same level as the rest of the surface used for floor simulation.

Figure 4 – Test plate with crevice
The length of the crevice should be approximately twice the outside width of the cleaning head.
4.2 Rollers for embedding
4.2.1 Dust embedding roller
The roller shall have a diameter of 50 mm and a length of at least 380 mm such that it is at
least 20 mm longer than the width of the dust-covered area. The roller is preferably made of
steel and polished. It can be provided with a handle for rolling by hand or be driven by a
motorized unit.
The mass of the roller, if applicable, shall be 10 kg/m. The roller can be incorporated into the
dust spreader as indicated in Figure 3.
4.2.2 Fibre and thread embedding roller
The roller shall have a diameter of 70 mm and a mass of 30 kg/m. The roller is preferably made
of solid steel and polished. It can be provided with a handle for rolling by hand or be driven by
a motorized unit. A convenient mass for rolling by hand is 15 kg.
4.3 Carpet beating machine
Whatever method or machine is used for the removal of residual test dust from the test carpet
shall not damage the carpet or the carpet backing. Figure 5 illustrates one example of a machine
suitable for removing all residual dust. This particular design consists of a horizontal cylinder
provided with thongs to beat the backing of the carpet when it is fed back and forth under the
rotating cylinder. Verification of reconditioning shall follow the procedure provided in the
particular product standard.
Figure 5 – Carpet beating machine
4.4 Verification of reference vacuum cleaner
4.4.1 General
In-house reference vacuum cleaners are devices used to control or determine variations in test
materials. All in-house reference vacuum cleaners utilized within a laboratory are recommended
to be verified on a regular basis using an appropriate method. Verification of an in-house
reference vacuum cleaner means to proof or improve its accuracy, i.e. its precision and
trueness.
In addition to in-house reference vacuum cleaners in general, the uniform reference vacuum
cleaner system RSB is a measuring aid exclusively used for the observation or correction of
dust pick-up test results on Wilton carpet related to daily variations of the carpet condition,
panel-to-panel deviations and changes in laboratory conditions. Thus, the RSB is a reference
vacuum cleaner designed to improve reproducibility in order to compare results across
laboratories. Therefore, the RSB shall be regularly validated by the RSB manufacturer every 3
years or 2 000 trials, whichever occurs first. Validation of the RSB means to improve the degree
of validity of this measuring aid by finding suitable validation values. Thus, the validation is
associated with the determination of the validation value DPUcal by means of testing the RSB
together with RSB 00 and is reported in a validation protocol.
The performance of the in-house reference vacuum cleaners utilized within a laboratory shall
be verified on a regular bases using an appropriate method. This also applies to the RSB if
used as an in-house reference vacuum cleaner. Appropriate verification methods are listed in
4.4.2 to 4.4.4.
Proper verification requires both air data tests of the in-house reference vacuum cleaner and
physical tests of its cleaner head appropriate to the floor type the in-house reference vacuum
cleaner is intended for. Measured and calculated values for the initial evaluations shall be
recorded as baseline values for future verification test results. The future verification tests shall
be conducted at least every 50 trials. Previous test results should be questioned if any issues
occur.
4.4.2 Air performance tests of reference vacuum cleaner
The air data of the reference vacuum cleaner shall be tested per IEC 62885-2:2021, 5.11,
alternative B with the base of the floor nozzle being connected to the plenum chamber. The
connecting tube, if present, shall be fully extended. The reference vacuum cleaner shall be set
to its maximum continuous performance level and all manual pressure relief valves shall be
closed. The corrected vacuum and input power (P ) for the 30 mm orifice plate from the initial
evaluation shall be recorded as the baseline values for future comparisons. Additional orifice
plates can be used if desired.
).
There shall be no greater than a ±10 % variation allowed for either vacuum or imput power (P
Should the values differ by more than the ±10 % limit, the in-house reference vacuum cleaner
shall be examined for possible damage including misplaced seals, cracked hoses or tubes,
incorrectly set power settings or fatigue of the fan.
4.4.3 Leakage test of cleaner head base
Additionally to the determination of air data, it can be helpful to check the leakage of the floor
nozzle or cleaner head.
