SURFACE CLEANING APPLIANCES –
Part 1: General requirements on test material and test equipment
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.
The main task of IEC technical committees is to prepare International Standards. In exceptional
circumstances, a technical committee may propose the publication of a technical specification
when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide whether
they can be transformed into International Standards.
IEC TS 62885-1, which is a technical specification, has been prepared by subcommittee 59F:
Surface cleaning appliances, of IEC technical committee 59: Performance of household and
similar electrical appliances.
This third edition cancels and replaces the second edition published in 2016. This edition
constitutes a technical revision.
This edition includes the following significant technical change with respect to the previous
edition:
a) Clauses 4 and 5 on test carpets have been combined into the new Clause 4;
b) a new Clause 5 has been added containing specifications and treatment of various kinds of
test dust;
c) a level loop test carpet specification has been added.
The text of this technical specification is based on the following documents:
Enquiry draft Report on voting
59F/390/DTS 59F/402/RVDTS
Full information on the voting for the approval of this technical specification can be found in the
report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all the parts in the IEC 62885 series, under the general title Surface cleaning appliances,
can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
IEC subcommittee 59F has agreed to make a collection of test material and test equipment
used in standards for testing surface cleaning appliances and to publish this collection as a
technical specification. The existing annexes published on the IEC web will be integrated in this
technical specification step by step.
Regular maintenance of the technical specification ensures that other standards which refer to
this TS always reference the current status regarding test material and test equipment.
This third edition complements the specification of the Wilton test carpet in the second edition
with the specification of a level loop test carpet and information on pre-treatment of test carpets.
Furthermore, the specification of various types of test dust has been included. Further test
material and test equipment specifications will follow.
The intention with this document is to ensure a minimum of test material types and common
use of these materials in tests of various surface cleaning appliances.
For information on supplies of test materials and details of test equipment, see Annex A.
Annex D provides general information relative to the various categories of dry vacuum cleaners.

INTRODUCTION
IEC subcommittee 59F has agreed to make a collection of existing and future test equipment
and materials used in testing surface cleaning equipment and to publish this collection as a
Technical Specification, which it intends to keep up to date. The existing Annexes published on
the IEC web will be integrated in this Technical Specification step by step.
This second edition complements the specification of the Wilton carpets in the first edition with
information on pre-treatment of new and replacement carpets. Further carpet specifications may
follow.
It is still the intention to supplement this Technical Specification with other test materials and
SC 59F, Surface cleaning appliances, is currently looking into possibilities to add specifications
concerning the various kinds of dust used.
The intention with this publication is to ensure a minimum of test material types and common
use of these materials in tests of various surface cleaning appliances.

4.2 Construction verification
4.2.1 General
The new carpet shall meet the construction specifications provided in Table 1. and Table 2.
Annex B provides an example of an evaluation of the initial production run of the production lot
BIC4 of the Wilton test carpet.
4.2.2 Performance verification
Additionally, interlaboratory testing shall be conducted to verify the measured performance
values for the RSB reference vacuum cleaner system RSB, with the passive nozzle and an
active vacuum cleaner. A minimum of six laboratories shall test the same vacuum cleaners on
samples of the new carpet and the previous carpet unique to each laboratory. Each carpet shall
be tested in accordance with IEC 62885-2:–, 5.3 and 6.2 by each laboratory and the results of
the two carpets shall be compared to determine differences between the old and new production
runs as well as overall variability of the new production run.
4.3 Pre-treatment of new and replacement carpets for testing
4.3.1 General
New and replacement carpets shall be conditioned prior to conducting recordable testing upon
them.
4.3.2 Pre-treatment of new Wilton test carpets for dust removal testing
Using a dry vacuum cleaner with a nozzle appropriate for the type of vacuum cleaners to be
tested on the carpet, and with a dust removal ability of 75 % ± 5 % on Wilton test carpets for
passive nozzles or 78 % ± 5 % on Wilton carpets for active nozzles, respectively, all loose fibre
is removed by vacuuming the entire surface of the carpet for 5 min. Weigh the amount of fibre
removed during this 5 min vacuuming period. If the amount of fibre removed is greater than
0,5 g, repeat the 5 min vacuuming and weighing procedures until less than 0,5 g is removed
during 5 min. Record the weight of the carpet.
After completing the fibre removal procedure, use an in-house reference vacuum cleaner with
a dust removal ability of 75 % ± 5 % on Wilton carpets for passive nozzles or 78 % ± 5 % on
Wilton test carpets for active nozzles, respectively, to conduct dust removal trials in accordance
with IEC 62885-2:—, 5.3. A minimum of ten trials shall be conducted. After that, continue
conducting trials until four consecutive trials vary by less than one percentage point (maximum
minus minimum dust removal ability) for the Wilton test carpet and category C carpets, and 3 %
for other carpets.
NOTE The category C carpet is described in IEC 62885-2.
It is important that the width of the nozzle used for preparing the carpet is bigger than the
nozzles to be tested.
Separate carpets shall be used for active nozzles and passive nozzles. These separate carpets
shall be clearly marked.
4.3.3 Verification of replacement carpets for dust removal testing
The in-house reference vacuum cleaner used for the pre-treatment of new carpets shall be used
to verify the suitability of replacement carpets when required. If the result deviation is greater
than five percentage points in dust removal ability compared to an internally defined fixed target
value, or to the original or first carpet used in the laboratory, then the new carpet may shall not
be used.
In any case, the carpet should shall not be used for more than 600 cleaning cycles.
4.4 Pre-treatment of new carpets for the determination of airborne acoustical noise
A new carpet shall be conditioned prior to conducting recordable testing upon it.
Using a dry vacuum cleaner with a nozzle appropriate for the type of vacuum cleaners to be
tested on the carpet, and with a dust removal ability of 75 % ± 5 % on Wilton test carpets for
passive nozzles or 78 % ± 5 % on Wilton test carpets for active nozzles, respectively, all loose
– 12 – IEC TS 62885-1:2020 RLV © IEC 2020
fibre is removed by vacuuming the entire surface of the carpet for 5 min. Weigh the amount of
fibre removed during this 5 min vacuuming period. If the amount of fibre removed is greater
than 0,5 g, repeat the 5 min vacuuming and weighing procedures until less than 0,5 g is
removed during 5 min. Record the weight of the carpet.
NOTE Energy Label and Ecodesign Regulations of the European Commission require noise levels to be determined
according to EN 60704-2-1 for household and EN 60335-2-69 for commercial vacuum cleaners. Declaration of noise
level is carried out according to IEC 60704-3 for household and IEC 60335-2-69 for commercial vacuum cleaners.
5 Standard test dusts
5.1 Simulated household dust
5.1.1 Background
In previous editions of standards for measuring the performance of dry vacuum cleaners, fine
dust was used to simulate the filling of the dust receptacle during use. This was sufficient as
long as a vast majority of vacuum cleaners was equipped with filter bags, often made of paper.
In the nineties, more and more bagless vacuum cleaners came onto the market that claimed to
experience no pressure drop when filling the dust container. The fine dust used for clogging
bagged vacuum cleaners was not suitable for bagless appliances.
Therefore, it became necessary to establish a synthetic test dust that should correspond to the
properties of real household dust with regard to morphology, dust propagation behaviour, dust
bag pressure drop and degree of geometric capacity filling of dust receptacles (including wet-
separating vacuum cleaner systems).
5.1.2 Composition of the simulated household dust
Based on a collection of dust receptacles from consumers, the properties of real household
dust were determined as a starting position for the development of the synthetic test dust. After
extensive testing it was found that a homogeneous mixture of
• 70 % by weight mineral dust type 3, in accordance with 5.1.3.1
• 20 % by weight cellulose dust in accordance with 5.1.3.2
• 10 % by weight second-cut cotton linters in accordance with 5.1.3.3
simulates real household dust for establishment of the filled dust receptacle condition best.
Figure 1 shows photographs under the microscope of real and simulated household dust. The
good correspondence between the fibrous and non-fibrous components is easy to see. Figure 2
shows the simulated household dust ready for use.

Average fibre length 30 μm
Average fibre thickness 18 μm
Bulk density 200 g/l to 260 g/l

scattered light method according to ISO 13320 is calibrated and controlled with a certified
reference material "BAM_D001" of BAM (Federal Institute for Materials Research and Testing,
Germany).
5.1.3.3 Cotton linters
The cotton linters shall be cut with an upper length of 4 mm with the typical length range given
in Table 5 in a linters screening mill. The fibre length (l) may be checked using a

5.1.4 Mixing of simulated household dust
5.1.4.1 General
The test dust may be prepared by adding to a mixing vessel the separate components,
alternating in the following order: mineral dust, cellulose dust, cotton linters. The mixing vessel
+3
shall be part of the tumble mixer, which can be operated at 28 rpm with a tilting angle of 15°
−0
for 5 min. The individual components as well as ready-mixed simulated household dust may be
obtained from the supplier (see Annex A).
During transportation and storage of ready-mixed test dust, a partial separation or compaction
of the material in the container will occur. Therefore, the supplier recommends the procedure
for re-mixing in accordance with 5.1.4.2_Preparation_after_delivery.
5.1.4.2 Preparation after delivery
Irrespective of the package size, simulated household dust is usually packed in 2 kg containers.
Vibrations and shocks during transport or delivery can cause the dust to segregate and become
compressed. It is therefore necessary to return the dust to its original bulk density and
homogenize it. For this purpose, a tumbler mixer is recommended that homogenizes the test
dust for 3 min to 5 min at a speed of 28 rpm and at a tilting angle of 15°. A representative
tumbler mixer is shown in Figure 3.

5.1.4.3 Sampling of simulated household dust
To ensure that measurement results are reproducible with simulated household dust, the dust
homogenized in accordance with 5.1.4.2_Preparation_after_delivery shall be evenly divided
into smaller samples. A decisive parameter here is the bulk density. If, for example, 2 kg
simulated household dust is divided into 50 g samples, it shall be ensured that all samples are
divided with the same bulk density. The following steps are recommended for portioning.
1) Acclimatize simulated household dust by storing the container open for at least 24 h under
test conditions.
2) Take 50 g of test dust using a measuring shovel.
3) Fill the test dust in a 100 ml beaker in which the bulk density can be monitored and weigh
the 50 g portion. If the bulk density is correct, it can be used for testing
4) Now take the next sample at a different location from the simulated household dust
container. Ideally, the sampling should be star-shaped (see the order 1 to 5 in Figure 4).
Figure 4 – Order of sampling (star-shaped)
5) Check always the bulk density in a beaker.
6) If you find during filling that the bulk density cannot be maintained, return the test dust to
the container and mix the test dust in the container using the measuring shovel. Now take
a new sample.
7) Repeat steps 4) and 5).

5.3 Debris
5.3.1 Background
The previous standards for measuring the performance of vacuum cleaners did not contain a
test for the pick-up of coarse material and debris. This was often criticised as a major
shortcoming of the standards. Some years ago, consumer test organizations developed and
successfully implemented their own tests for the pick-up of debris. But, often, organic goods
such as rice and lentils are used.
In the meantime, standardization has also developed tests for determining the pick-up of coarse
material for household vacuum cleaners. In general, test methods should be repeatable and
reproducible. It is obvious that organic test materials such as rice and lentils have very large
variations in shape and dimensions and are therefore not suitable for reproducible tests.
For this reason, standardization has set itself the task of replacing organic test materials with
synthetic materials for which specifications or standards exist and which are widely available.
5.3.2 Medium size debris
Rice and lentils, as used by consumer testing organisations, were analysed for shape, weight
and dimensions. On this basis, non-organic materials were searched for, which on the one hand
represented rice and lentils as well as possible, but on the other hand were also specified and
widely available.
The following standardised replacement materials were found to replace rice and lentils.
Figure 6 illustrates the close match regarding shape, weight and dimensions between the
identified non-organic materials, set screws and nuts, and rice and lentils, respectively. The
corresponding specification is shown in Table 8.
