Surface cleaning appliances - Part 8: Dry vacuum cleaners for commercial use - Methods for measuring the performance

IEC 62885-8:2019 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.
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.
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.
This first edition cancels and replaces IEC PAS 62611, published in 2009.

Methods for measuring the performance
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

For the purposes of this document, the terms and definitions given in IEC 60335-2-69 and the

following apply.

ISO and IEC maintain terminological databases for use in standardization at the following

addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
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.
---------------------- Page: 8 ----------------------
IEC 62885-8:2019  IEC 2019 – 7 –

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

---------------------- Page: 9 ----------------------
– 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 =
where
d = distance between next neighbours of debris component and
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

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) + […] +
de de de de de de de de de
k (19) + k (20)) / 20
de de
k ×100
where
k is the debris removal ability for a single cleaning cycle, in percent;
m is the debris quantity in the testing area before cleaning, in parts;
m is the debris quantity remaining on the testing area after cleaning, in parts;
---------------------- Page: 11 ----------------------
– 10 – IEC 62885-8:2019  IEC 2019

Two test sequences have to be carried out. One starting with a forward stroke and one

starting with a backward stroke. Each test sequence consists of ten separate tests. Each

test shall be carried out to establish a mean value of the debris removal ability for five double

strokes, to be reported separately.
