of a size equal to or larger than the test carpet.
Equipment and materials for measurements (devices, test carpets, test dust, 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.
Carpets that have already been used shall be stored unbeaten at standard atmospheric conditions in
accordance with 4.1.
When not in use, carpets shall be hanging free, or lying flat, pile upwards and uncovered. Carpets shall
not be rolled when stored between testing. Carpets that have been rolled shall be laid flat for a minimum
of 16 h before use.
4.2.2 Pile direction
Machine or manufacturing direction is an indication of the projected pile direction for carpet production.
Pile direction is what is important for dust pick-up (DPU) testing.
If the pile direction is clearly parallel to the test bed, as is required by the applicable test procedures, the
carpet is acceptable for use for that test. If the pile direction is at an angle to the test bed, the laboratory
will be required to decide as to that carpet panel's usability for relevant comparative testing.
NOTE The procedure for determining pile direction can be found in IEC TS 62885-1:2020.”

“If the dry vacuum cleaner is provided with a reusable dust receptacle (as the sole original dust
receptacle or as an enclosure for disposable dust receptacles), the dust receptacle and any additional
filters removable without the aid of tools shall, prior to each measurement, be cleaned according to the
manufacturer's instructions until its mass is within 1 % or 2°g of its original mass, whichever is the lower.”
Replace the 4th and 5th paragraph with:
“For dry vacuum cleaners equipped with separation devices, being part of the appliance, used to
separate the dust from the air flow and/or having additional filters to be changed or cleaned by the user,
without the use of tools, the change in mass of such specific devices shall be taken into account for dust
removal ability.
Dry vacuum cleaners with disposable or reusable dust receptacles may have secondary filtration stage
devices which do not collect meaningful dust in removal ability tests, but which do impact on filtration
and life tests. Replacement and/or maintenance of such devices shall be in accordance with relevant
clauses and carried out according to the manufacturer's instructions.“
4.6 Operation of the vacuum cleaner
Replace title with:
“Operation of the dry vacuum cleaner”
4.6.1 General
Replace with:
“The grip of cleaners with suction hose or the handle of other cleaners shall be held 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 may be adjusted. 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 to EN IEC 60704-2-1:2020:
“For declaration and compliance purposes, related tests conducted on a surface type (carpet or hard
surface with or without crevice) shall be conducted with the same dry vacuum cleaner setting
configurations such as power, cleaning head and cleaning head setting.”
Related tests are:
— tests measuring the dust removal from carpet, the debris removal from carpet, the energy
consumption for cleaning a carpet, and the noise level on carpet.
— tests measuring the dust removal from hard floor with crevices, the debris removal from hard floor,
the energy consumption for cleaning a hard floor with crevices, and the noise level on hard floor.
Unless otherwise specified, the dry vacuum cleaner setting configurations, such as power, cleaning
head and cleaning head setting, shall be used, and adjusted in accordance with the manufacturer's
instructions for the surface to be cleaned (e.g. carpet or hard floor) for the test to be carried out.
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 suction 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.”
4.6.2 Operation of water filter vacuum cleaners, additional requirements
4.6.2.1 Determining the water loss
Replace with:
“Prior to the preconditioning the water loss of the water filter vacuum cleaner shall be determined.
The water filter vacuum cleaner shall be run according to the manufacturer's instructions for a period
of 10 min with the suction nozzle lifted 20 mm from the floor in accordance with 4.1. Before and after
this running time of 10 min the mass of the water filter system shall be measured with an accuracy of at
least 0,1 g. This trial shall be repeated 3 times and an average of these 3 trials shall be noted.
Since ambient conditions have a significant influence on the water loss, standard conditions shall be
carefully maintained.”
4.6.2.2 Filter conditions
Replace with:

4.6.2.2.1 For dust and debris removal from hard flat floors and from carpets
If the value measured according with 4.6.2.1 is lower than 0,1 g/min, the water filter vacuum cleaner
shall be used in accordance with the manufacturer's instructions for the dust removal from hard flat floors
and carpet.
The water filter vacuum cleaner should not be moved to minimize loss of water.
NOTE 1 The mass of water lost during the measuring time is low and has no relevant influence on the test result.
If the value measured according to 4.6.2.1 is equal or higher than 0,1 g/min and the water filter vacuum
cleaner is equipped with a dust collection system that does not use water, this collecting system shall
be included to determine the dust and debris removal from hard flat floors and dust and debris removal
from carpet.
The air data in accordance with 5.11 shall be measured with the water filter system used according to
the manufacturer's instructions. Then the vacuum cleaner shall be equipped with the dust collecting
system without water and the maximum airflow shall be adjusted to ± 3 % of the measured values with
water filter system.
In all other cases, the dust and the debris removal from hard flat floors and from carpets shall be
performed using the dust collecting box (see 7.3.Z2) as pre-filter system. The vacuum cleaner shall be
used in accordance with the manufacturer's instructions.
The dust collecting box is equipped with a synthetic filter bag properly sized for the dust collecting box.
NOTE 2 The filter bag from the reference vacuum cleaner system RSB in accordance with 3.Z1 can be used.
For measuring dust pick-up, the filter bag can be handled in the same way it is handled in the reference vacuum
cleaner system RSB.
4.6.2.2.2 For all other tests with water filter vacuum cleaners
The vacuum cleaner and its attachments shall be used and adjusted in accordance with the
manufacturer's instructions for normal operation for the test to be carried out.

4.7 Conditioning prior to each test
Replace the words “vacuum cleaner” by “dry vacuum cleaner”.
4.8 Mechanical operator
Replace with:
“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 against the test surface.
It is recommended to simulate the handling of the dry vacuum cleaner by using a mechanical operator
such as that described in 7.3.12.”
4.9 Number of samples
Replace the phrases “vacuum cleaner” by “dry vacuum cleaner”.
Delete the NOTE.
Add as paragraph after the 1st paragraph as follows:
“For increased confidence in the test results, a minimum of three samples of a dry vacuum cleaner
should be tested. Some performance tests may require additional samples or replacement parts if
performance is adversely impacted by testing. If additional samples or replacement parts are used, they
should be recorded in the report.
Tests carried out to simulate stresses that a dry vacuum cleaner may 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.

4.Z1 Carpets for testing
NOTE 1 The reference cleaner referred to in this document is a product designated within a laboratory for
internal comparison and is not suitable for inter-laboratory comparisons.
Test carpets used in a laboratory for the determination of dust removal ability will, over time, change
from their original condition, for instance due to wear or gradual filling with dust. Therefore, the in-house
reference cleaner as defined in 3.Z8 shall be used to regularly check the carpet conditions as a
verification of the test results obtained and recorded.
If a reference vacuum cleaner system RSB as defined in 3.Z1 is present, this should be used for
monitoring Wilton test carpet conditions by comparing the values for calibrated and reference dust pick-
up, DPU and DPU , of the RSB.

NOTE 2 DPU and DPU are defined in Clause ZB.5.

If the difference between DPU and DPU is greater than 5 percentage points, it is recommended

to:
— replace the carpet, and/or
— re-adjust the RSB, and/or
— check the laboratory conditions and testing procedure.
Given that dust pick-up ability can differ between carpets used for active nozzles or passive
nozzles, the result from tests between active nozzles and pa
