“4.6 Operation of the vacuum cleaner
4.6.1 General
The tube grip of cleaners with suction hose or the handle of other cleaners shall be held as
for normal operation at a height of (800 ± 50) mm above the test floor.
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 60704-2-1,
and EN 60335-2-2. For declaration and compliance purposes, related tests for a given
cleaning task shall be conducted with the same dry vacuum cleaner setting configurations
such as cleaning head and cleaning head setting.
NOTE 1: Related tests are all tests related to a given cleaning task. They include tests relevant to the Energy
Labelling and Ecodesign requirements for cordless dry vacuum cleaners.
NOTE 2: Related tests are:
- tests measuring the dust 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 and the energy consumption for cleaning a
hard floor with crevices and the noise level on hard floors (for noise measurement regarding Energy Label /
Ecodesign refer to Regulations 665/2013 and 666/2013).
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 separate
electrical specific vacuum motor settings shall be set for maximum continuous airflow and,
unless the manufacturer’s instructions states otherwise, any manually operated air by-pass
opening for reduction of the suction power shall be closed.
In the absence of unambiguous instructions within the user manual 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 are to be recorded in the test
documentation.
Where a manufacturer publishes/declares values for the performance of its product, e.g. in
the Technical Documentation, it shall provide accurate and unambiguous details of the
settings that were used during the test procedure.
NOTE 3: Performance in other settings/combinations may differ from the results in the declaration settings,
however the standard does not address those results.
4.6.2 Operation of water filter vacuum cleaner, additional requirements
4.6.2.1 Determining the water loss
Prior the preconditioning the water loss of the water filter vacuum cleaner shall be
determined.
The water filter vacuum cleaner has to run according manufacturer’s instructions for a period
of 10 min with the suction nozzle lifted 20 mm off the floor at standard temperature and
standard relative humidity. Before and after this running time of 10 min the weight of the water
filter system shall be measured with an accuracy of at least 0,1 g. This test shall be repeated
three times and an average of these 3 tests shall be noted.
The ambient condition have a big influence on the water loss. Temperature and air humidity
will have impact on the results. Therefore the temperature and air humidity should be
controlled carefully.
4.6.2.2 Filter conditions
4.6.2.2.1 For dust removal from hard flat floor (see 5.1) and from carpet (see 5.3)
If the value measured according to 4.6.1.1 is lower than 0,1 g/min the water filter vacuum
cleaner shall be used according to manufacturer’s instructions for the dust removal from hard
flat floors and carpet.
NOTE: The mass of water which is lost during the measuring time is low and has no relevant influence on the test
result.
Water Filter vacuum cleaners should not be moved to minimize the loss of water.
If the value measured according to 4.6.1.1 is equal or higher than 0,1 g/min and the water
filter vacuum cleaner is equipped with a dust collection system which doesn’t use water, this
collecting system will be included to determine the dust removal from hard flat floors
according to 5.1.6 and dust removal from carpets according to 5.3.
The air data according to 5.8.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 the water filter system.
In all other cases the dust removal from hard flat floors and from carpet shall be performed
using the dust collecting box (see 7.3.Z2 Dust collecting box) as a pre filter system. The
vacuum cleaner shall be used according to manufacturer’s instructions.
The dust collecting box is equipped with a filter bag. The filter bag from the reference vacuum
cleaner system could be used. For measuring dust pick up the filter bag shall be handled in
the same way as it is handled in the reference vacuum cleaner system
4.6.2.2.2 For all other tests with a water filter vacuum cleaner
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.”

“5.11 Filtration efficiency and dust re-emission of the vacuum cleaner
5.11.1 Purpose
The aim of this test is to determine the ability of a vacuum cleaner to retain dust, depending
on particle size, from the intake aerosol containing a predefined concentration of test dust.
This test is not suitable for determining permeability of filters or filter materials.
5.11.2 Test conditions
NOTE A relative humidity of 45 % RH to 55 % RH is recommended for control of static.
Measuring equipment required for the test is specified in 7.3.8.
In preparation of the test, the vacuum cleaner should be equipped with a new or thoroughly
cleaned dust receptacle and new filters according to specifications. It is to be set to operate at
maximum airflow.
The vacuum cleaner is placed centrally under the test hood in its normal operation condition.
Dust will be fed
• to vacuum cleaners with a suction hose, through this hose,
• to vacuum cleaners without a suction hose (for instance Uprights) through a suitable
auxiliary hose which is connected and sealed tightly to the suction nozzle by use of a
nozzle adaptor.
For water filter vacuum cleaner distilled water shall be used for measuring the filtration
efficiency. The amount of water shall be taken from the manufacturer’s instructions. In order
not to measure water droplets a diffusion dryer shall be added to the inlet of the particle
counter.
5.11.3 Determining the test dust quantity
For the entire duration of dust, according to 7.2.2.5 being fed, the dust concentration c shall
in the intake aerosol channel. Therefore, the maximum airflow q for the vacuum
be 0,1 g/m
cleaner with the given filter equipment shall be determined.
The quantity m of dust to be fed for duration t is calculated consequently as
DUST
m= c×t ×q

5.11.5 void
5.11.6 Test procedure
5.11.6.1 General
A test run can be conducted either by using two particle counters which read intake and
exhaust values simultaneously or by using a single particle counter which is switched for
reading intake and exhaust values, respectively.
Particle registration is by particle analysing system (see 7.3.8.5) which can be operated with a
suitable aerosol dilution system to adapt count rate capacity and the particle concentration of
aerosol intake and of exhaust channel, respectively. The results of any single trial shall be
recorded as follows:
• counter events / class; i.e. the number of events recorded by the particle counter,
separately for each range of particle size as well as for aerosol intake channel and
exhaust channel;
• sample air volumes, VA (exhaust) and VA (intake); i.e. the volumes of the aerosol
Ex In
samples analysed by the particle counter combined in the course of the trial;
• applicable dilution factors k (intake or exhaust) of the particle analysis system; i.e.
VA
the ratio between the volume of the air sample extracted from the channel and the
sample air volume analysed by the particle counter.
The following test procedure for a single trial may be repeated with several dry vacuum
cleaners of identical type. Then the final result of the test run has to be averaged
arithmetically.
NOTE 1 Proper dilution ratio needs to be verified. Prove not over-concentrated by serial dilution and prove not
over-diluted on the exhaust by lessening the dilution serially, see 7.3.8.5.
NOTE 2 There are known issues with the particle transport within this test. Measures are under development to
ensure and verify a proper particle transport. Changes may be necessary to the measuring equipment or to the way
the test is performed.
5.11.6.2 Single particle counter procedure
A single trial proceeds as follows:
• the dry vacuum cleaner is operated without dust being fed until acceptable and stable
conditions are achieved (minimum 10 min, maximum 30 min). This method stability is
± 10 % for particle counts over 100 for 30 s or less than 100 particle counts per 30 s
over at least 10 min.
• conditioning: dust is fed for 10 min while the particle concentration in the aerosol
intake channel is monitored (quantity of test dust according to 5.11.3),
• sampling: feeding of dust is continued for approximately 10 min during which 5 test
cycles are carried out, each consisting of:
• particle registration from aerosol intake channel for 30 s (intake measurement),
• flushing of particle analysing system with the applicable sample stream for ≥ 10 s,
• particle registration from exhaust channel for 30 s (exhaust measurement),
• flushing of particle analysing system with the applicable sample stream for ≥ 10 s.
5.11.6.3 Dual particle counter procedure
If two particle counters are used, they need to be verified to match in calibration and count
rate. Their particle counts have to be within 10 % in each range of particle size for particle
counts over 100 for 30 s.
A single trial proceeds as follows:
• the dry vacuum cleaner is operated without dust being fed until acceptable and stable
conditions are achieved (minimum 10 min, maximum 30 min). This method stability is
± 10 % for particle counts over 100 for 30 s or less than 100 particle counts per 30 s
over at least 10 min.
• conditioning: dust is fed for 10 min while the particle concentration in the aerosol
intake channel is monitored (quantity of test dust according to 5.11.3),
• sampling: feeding of dust is continued for 150 s during which 5 test cycles are carried
out, each consisting of continuous particle registration from both aerosol intake
channel (intake measurement) and exhaust channel (exhaust measurement) for 30 s.
5.11.7 Evaluation
5.11.7.1 General
Based on the particle counts obtained in the 5 measurement cycles, for aerosol intake
channel and exhaust channel, the evaluation can be done either for
• fractional filtration efficiency (for each class of particle size) or
• filtration efficiency for the entire range of particle size (i.e. from 0,3 µm to 10 µm).
Filtration efficiency E for the entire range of particle size is 1 minus the ratio of number of
particles exhaust and number of particles intake.
Dust re-emission R for the respective range of particle size is defined as 1 minus E which is
the ratio of number of particles exhaust and number of particles intake.
The basic formulae are:
E = 1 - R
R = 1 - E
The detailed determination of E and R for a range of particle size including consideration of
the 95 % confidence level is shown below.
5.11.7.2 Evaluation of fractional filtration efficiency
Based on the particle counts obtained in the 5 measurement cycles, for aerosol intake
channel and exhaust channel, the fractional filtration efficiency is derived for each particle
class.
The individual measurements are considered to be samples of a full distribution, and a
statistical analysis is performed accordingly.
Given the particle counts of the aerosol intake channel for particle class k obtained

5.11.8 Particle concentration and dilution
For flawless particle registration and analysis it has to be monitored and maintained that the
particle concentration at the counter is within its specified range of proper operation and that
each individual particle count z is well below the maximum count z , such that
SAMPLE COUNTER_MAX
z < 0,2 z
SAMPLE COUNTER_MAX
.
To verify not over-concentrated, increase the dilution a known amount, and verify that the
counts are decreased by the same ratio.
To verify not over-diluted, decrease the dilution and verify that the counts increase by this
same change in dilution ratio.
5.11.9 Record keeping
A record with the following information shall be kept for each test of filtration efficiency and
filtration efficiency and dust re-emission for the entire range of particle size:
• electrical and air-technical data of the type of at least 3 devices being tested;
• information on its dust receptacle and filter system;
• quantity of test dust being fed in the procedure;
• information on the particle analysis system:
• particle counter and size ranges of analysed particle classes
• dilution factors intake and exhaust
• for each particle count:
• dilution factor
• sample air volume analysed in the particle counter
• particle counts in each class registered by the particle counter
• filtration efficiency (lower limit of 95 % - confidence range) of each particle class;
• filtration efficiency (lower limit of 95 % - confidence range) for entire range of particle size;
• dust re-emission for entire range of particle size;
• sheath air if applicable;
• vacuum cleaner air flow rate.”
12 Modification to 6.7.4
Add after first paragraph:
“Water filter vacuum cleaners are loaded with sand which has the equivalent weight of the
nominal water according to the manufacturer’s instructions. No water is used.”
13 Modification to 6.9.1
Add after first paragraph:
“This test is only applicable to hoses that constitute the primary structural link between the
floor-supported main body of a cylinder vacuum cleaner and a separate cleaning head or
cleaning head/tube assembly that, in normal use, is used to clean a floor from an upright
standing position (see Figure Z.1).
This test is not applicable to hoses that, in normal use, remain affixed at both ends to a
vacuum cleaner with a cleaning head that, in normal use, forms an integral part of, or is
permanently connected to, the vacuum cleaner housing. This configuration can often be found
on upright vacuum cleaners. (see Figure Z.2). Such hoses may be released at one end to
allow other cleaning tasks to be carried out (see Figure Z.3).
NOTE A test regarding durability of such hoses is under development.
Figure Z.1 – Typical cylinder Figure Z.2 – Typical upright vacuum cleaner with
vacuum cleaner with primary hose secondary hose (contour front and back)
Figure Z.3 – Typical upright vacuum cleaner with secondary hose used for cleaning
curtains (left) and stairs (right).
This test is not applicable for:
• Hoses that are permanently housed within other components of a vacuum cleaner, or
that cannot be removed from a vacuum cleaner without the use of tools;
• Hoses that join two or more components, where, in all usage modes, the structural link
between those components is provided by features other than the hose itself (an
example is shown in Figure Z4);
• Hoses that are provided as additional accessories or where another primary hose is
provided for general use.
Figure Z.4 – Example of a hose joining two or more components.”
14 Modification to 6.9.3
Add a note after second paragraph:
“NOTE 2,5 kg is the total of the weight, the attachment cord and its attachment to the hose.”
Add in last paragraph as an additional sentence within the same clause:
“Additionally, breaking or damaging of the conductors, or an increase of more than 10 % of
the conductor resistance, is considered to be a failure for current-carrying hoses.”
15 Modification to 6.10.3
Add in fourth paragraph as an additional sentence within the same clause:
"Water filter vacuum cleaners are emptied and refilled with water according manufacturer’s
instructions every 50 h ± 5 h."
16 Add a subclause 6.Z3
Add new subclause:
“6.Z3 Operational motor life-time test
6.Z3.1 Purpose
The purpose of this test is to determine the stationary operational life-time of a dry vacuum
cleaner suction and agitation device motor.
6.Z3.2 Test method
The dry vacuum cleaner, equipped as in its normal operation with hose and tube (if
applicable) and nozzle, shall be operated as stated in 4.6. It is allowed to run intermittently
with periods of 14 min 30 s on and 30 s off in maximum power setting.
This test is operated with a half loaded receptacle; hence the dust receptacle shall be loaded
with 50 % of the amount of test dust required according to 5.9.
Alternatively an empty dust receptacle can be used during the test. In this case the
recommended testing time shall be increased by 10 % of the stated motor life value for testing
with a half loaded dust receptacle.
The tube grip of dry vacuum cleaners with suction hose or the handle of other dry vacuum
cleaners shall be held as for normal operation at a height of 800 mm ± 50 mm above the test
floor.
The nozzle shall not be in contact with the floor, but lifted 1 cm off the floor.
If the dry vacuum cleaner is provided with an agitation device it shall be running. If
manufacturer’s instructions require different settings of the agitation device for use on carpets
and use on hard floor, the agitation device shall be operated with the respective settings for
50% each of the total testing time.
Test with half loaded dust receptacle:
After 50 h ± 5 h of operation, the vacuum cleaner shall be equipped with a clean dust
receptacle and new filters (see 4.5).This procedure, with the receptacle loaded with the same
amount of test dust as for the first cycle, shall be repeated in steps of 50 h ± 5 h.
Test with empty dust receptacle:
After 100 h ± 5 h of operation, the vacuum cleaner shall be equipped with a clean dust
receptacle and new filters (see 4.5).
Changing or maintenance of dust receptacles and filters shall be carried out in accordance to
the manufacturer's instructions and this shall be recorded, see 4.5.End of life is reached when
the suction motor and, if applicable, the agitation device stops operating or the recommended
testing time has elapsed.
NOTE The 30 second off period is not included in the calculation of overall motor life.”
17 Modification to 7.3.2
Delete text and replace with the following text:
"The equipment consists of a wood panel provided with a removable insert of aluminium
having a 3 mm ± 0,05 mm wide and 10 mm ± 0,05 mm deep smooth crevice (see Figure 18)”.
18 Modification to 7.3.8.1
Replace “upstream” with:
"intake”
Replace “downstream” with:
"exhaust”
19 Modification to 7.3.8.5
Add in first sentence of fourth paragraph before “0,3 µm":
“at least”
Replace in second sentence of fourth paragraph “These” by:
"For the determination of fractional filtration efficiency these”
Add at the end after Table 2:
“For the determination of filtration efficiency and dust re-emission for the entire range of
particle size this particle size range is divided into classes in such a way that one class has
the lower limit of 0,3 µm and one class has the upper limit of 10 µm.”
20 Modification to 7.3
Modification of EN 60312-1:2013 7.3.Z1 Reference vacuum cleaner system
Renumber Figure from Figure Z.1 to Figure Z.5.
