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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

SURFACE CLEANING APPLIANCES –
Part 8: Dry vacuum cleaners for commercial use –
Methods for measuring the performance

1 Scope
Replace the scope of IEC 62885-2:2016 by the following:
This part of IEC 62885 is applicable for measurements of the performance of mains-operated
dry vacuum cleaners, including water filter vacuum cleaners, for commercial use. The
requirements for the construction and testing covered by this document are applied in addition
to the requirements for commercial vacuum cleaners in IEC 60335-2-69.
The purpose of this document is to specify essential performance characteristics of dry
vacuum cleaners for commercial use that are of interest to operators and to describe
methods for measuring these characteristics.
NOTE 1 Due to the influence of environmental conditions, variations in time, origin of test materials and
proficiency of the operator, some 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.
NOTE 2 The methods here can be applied with modifications for surface-cleaning product types or technologies
not currently covered within the scope.
For safety requirements, reference is made to IEC 60335-1 and IEC 60335-2-69.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements of this document. For dated references, only the edition
cited applies. For undated references, the latest edition of the referenced document (including
any amendments) applies.
This clause of IEC 62885-2 is applicable with the following modifications:
Delete the references IEC 60704-1 and IEC 60704-2-1 and replace by the following reference:
IEC 60335-2-69, Household and similar electrical appliances – Safety – Part 2-69: Particular

4 General conditions for testing
This clause of IEC 62885-2:2016 is applicable with the following modifications:
4.6 Operation of the dry vacuum cleaner
4.6.1 General
Replace the content of 4.6.1 by the following:
The tube 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. 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 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
IEC 60335-2-69: "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."
The dry vacuum cleaner setting configurations, such as 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. Any electrical
controls shall be set for maximum continuous airflow for the floor surface setting and, unless
the manufacturer’s instructions state otherwise, any manually operated air by-pass opening
for reduction of the suction power shall be closed. A boost function on the vacuum cleaner,
changing the normal operation mode as stated by the manufacturer, is not activated during
any measurement. The maximum operational power including the boost function shall not
exceed the result from the rated input power measurement as declared by the manufacturer,
in accordance with IEC 60335-2-69. Motion resistance, as determined in 6.2, shall not be
larger than 40 N for operating the commercial dry vacuum cleaner to determine its
performance.
NOTE 1 A motion resistance of maximum 40 N is seen as acceptable for application in a professional
environment. Higher motion resistance contradicts continuous duty in a professional environment owing to the
large force to be applied by the operator during usage, which contradicts the applicability.
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 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 2 Performance in other settings/combinations may differ from the results in declaration settings, however,
the document does not address those results.
NOTE 3 Ecodesign Regulation of the European Commission requires noise levels to be determined and declared
in accordance with EN 60335-2-69.
5 Dry vacuum cleaning tests
This clause of IEC 62885-2:2016 is applicable, with the following additions:
5.3 Dust removal from carpets
5.3.1 Test carpet
Add, after the last paragraph, the following two sentences:
The two carpet hold-downs serve the purpose of holding the test carpet in position during test,
and of acting as guides to keep the cleaning head in a straight line as it is moved over the
test area. The guides should have a distance of 10 mm from the carpet's surface to ensure an
undisturbed flow.
5.101 Debris removal from hard floor
5.101.1 Test equipment
The surface is conditioned once before the first use, in accordance with 7.3.101. Conditioning
only needs to be repeated if the surface is also used for other testing that could impair the
smoothness of surface.
Two hold-downs in accordance with 7.3.4 serve the purpose of acting as guides to keep the
cleaning head in a straight line as it is moved over the test area. The guides should have a
distance of 10 mm from the surface to ensure an undisturbed flow.
5.101.2 Test area and stroke length
The double stroke shall start with a forward stroke for the first test sequence and with a
backward stroke for the second test sequence on the test area. The length of the test area is
700 mm ± 5 mm. The width of the test area is equal to the cleaning head width (see 3.7).
A length of at least 200 mm shall be added before the beginning of the test area and at least
300 mm added after the test area in order to allow for acceleration and deceleration of the
cleaning head. The stroke speed at the deceleration zone shall for the first 50 mm shall not
drop below (0,45 ± 0,02) m/s to ensure that the contact time between nozzle and debris
pushed into the deceleration area is not enlarged artificially.
Thus, the stroke length is between 1 200 mm and 1 600 mm for the given test length of
700 mm. The centreline of the front edge of the cleaning head is aligned to the centreline of
the beginning of the acceleration area at the commencement of the stroke, allowing a
distance between 200 mm and 300 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
between 200 mm and 600 mm past the end of the test area, thus allowing a suitable distance
for deceleration. The reverse stroke is carried out in the same manner until the front edge of

– 8 – IEC 62885-8:2019  IEC 2019
the cleaning head is once again lined up with the beginning of the acceleration length in front
of the test area.
The active depth of the cleaning head shall move at a uniform stroke speed of 0,50 m/s ±
0,02 m/s and in a straight line over the test area.
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 is determined by
the dry vacuum cleaner. For optimum control of the double stroke movement, it is
recommended that a mechanical operator (see 4.8) be used.
5.101.3 Distribution of test debris
Debris is placed flat on the test on the surface perpendicular to the direction of motion of the
nozzle as given in Figure 101. Firstly, three rows, each consisting of 5 washers, followed by
three lines of nuts. The rows are arranged alternately every 140 mm with respect to the hold-
downs and the motion direction: the odd lines are aligned with the right hold-down, the even
lines with the left hold-down, each with a distance of 15 mm. The distance of neighbouring
debris components depends on the nozzle width and is calculated as follows:
w −15
nozzle
d =
nn
where
d = distance between next neighbours of debris component and
nn
w = nozzle width (equal to cleaning head width B).
nozzle
All the distances refer to the centres of the drop-off points of the debris components. So, the
outermost washer of the first line starts with a distance of b = 15 mm to the right hold-down,
then distance of the next neighbouring washer is d , etc. The next line with washers is
nn
aligned to the left hold-down etc. Figure 101 shows a sketch of a thus obtained debris pattern.
The nuts used for the tests shall be hexagon regular nuts of types ISO 4032 – M3 – CU2,
made out of brass CuZn37. In order to ensure consistency, the mass of the nuts need to be
within a tolerance range; 100 nuts shall have a mass of between 32,0 g and 35,0 g.
The washers used for the tests shall be plain washers, normal series of types ISO 7089 – 3 –
200 CU2, made out of brass CuZn37. In order to ensure consistency, the mass of the washers
need to be within a tolerance range; 100 washers shall have a mass of between 10,0 g and
12,0 g.
Additionally, it shall be ensured that the washers and nuts, lying flat on the test surface, have
a smooth surface and are free of sharp edges.

Figure 101 – Debris distribution and distances
5.101.4 Determination of debris removal ability
Prior to starting the test, the vacuum cleaner is conditioned by letting it run for 10 minutes.
After this, the cleaning head is passed over the testing area by performing double strokes,
starting with a forward stroke or a backward stroke as described in 5.2.3, in a parallel
pattern at a stroke speed of (0,50 ± 0,02) m/s, keeping the cleaning head to the centre of
the test plate. The quantity of debris removed from the surface after five double strokes is
determined as the difference of the amount of debris before and after cleanings, both values
being recorded. The test is finalised after ten cleaning cycles. It shall be ensured that before
lifting the nozzle after the test, the vacuum cleaner shall be switched off. Any debris inside or
stuck in the brush, if applicable, of the nozzle shall be regarded as not having been picked up.
NOTE The test consists of 20 cleaning cycles where 10 cycles start with a forward stroke and 10 cycles start
with a backwards stroke.
The debris removal ability, in per cent, is calculated in accordance with the following formula
as the ratio of the quantity of debris removed to the quantity of debris initially laid onto the
testing area.
The mean value of dust removal ability for 20 cleaning cycles is calculated as follows:
(20) = (k (1) + k (2) + k (3) + k (4) + k (5) + k (6) + k (7) + k (8) + […] +
