Vacuum cleaners for household use - Part 1: Dry vacuum cleaners - Methods for measuring the performance (IEC 60312-1:2010, modified + A1:2011, modified)
This International Standard is applicable for measurements of the performance of dry vacuum cleaners for household use in or under conditions similar to those in households. The purpose of this standard is to specify essential performance characteristics of dry vacuum cleaners being of interest to the users and to describe methods for measuring these characteristics. NOTE 1 Due to influence of environmental conditions, variations in time, origin of test materials and proficiency of the operator, most 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 This standard is not intended for battery-operated vacuum cleaners. For safety requirements, reference is made to IEC 60335-1 and IEC 60335-2-2.

"4.Z1 Reference vacuum cleaner system
Test carpets used in a laboratory for the determination of dust removal ability will, over time,
change from their original conditions, for instance due to wearing or gradual filling with dust. It
is therefore required that the reference vacuum cleaner system as defined in 3.17 be used to
regularly check the carpet conditions as a verification of the test results obtained and being
recorded.
The reference vacuum cleaner system is designed to obtain 75 % of dust removal after 5
double strokes, both with passive and active nozzle (only for carpet).
The reference vacuum cleaner system has to be tested on each carpet used prior to each
sample testing and the test results shall be recorded, after correction according to 6.17.2.2 by
using the calibrated dust removal ability K . The expected result should be near to the 75 % of
c
dust removal ability after 5 double strokes, however a deviation of ± 5 % is allowed.
NOTE In case the deviation exceeds the ± 5 % limit, the test carpet can be replaced or the reference vacuum
cleaner system can be calibrated by the manufacturer.
Due to the fact that dust pick-up ability may differ between carpets used for active or passive
nozzles, the result from tests between active and passive nozzles shall not be compared.
Test carpets designated for testing of passive nozzles shall only be cleaned with a passive
nozzle on the face. Test carpets designated for testing active nozzles shall only be cleaned

6.Z1 Determination of energy efficiency
6.Z1.1 General
This subclause refers to mains powered dry vacuum cleaners only; hybrid vacuum cleaners
have to be tested with the battery removed or disconnected.
Since “energy consumption” alone is not linked to a certain cleaning result “energy
consumption” and “dust removal ability” have to be measured and brought into a defined
relationship called “energy efficiency”.
“Energy efficiency” is calculated from the figures of “energy consumption” and “dust removal
ability”.
6.Z1.2 Determination of energy efficiency on carpets
6.Z1.2.1 Determination of energy consumption
The energy consumption on carpets is determined according to 6.16.1
6.Z1.2.2 Reference level
The reference level is fixed to a dust removal ability of 65 % on a Wilton test carpet according
to 7.2.1.3.2. To consider the reproducibility on different test carpets and the deviations from a
test carpet's original conditions the reference vacuum cleaner system as described in 4.10 is
used to measure and normalise the reference level K according to the specific conditions of
calc
the test carpet used for the determination of energy efficiency.
To determine the normalised reference level of the carpet used for energy efficiency
measurement, the dust removal ability of the test carpet is measured according to 5.3. The
dust removal ability in per cent is then normalised by applying the calibration value, which is
given with the reference cleaner system using the following formula:
K = K / K x 65%
calc ref c
K : Measured dust removal ability of the reference vacuum cleaner system on the test
ref
carpet used for the determination of energy efficiency
K : Calibrated dust removal ability of the reference vacuum cleaner system used for
c
the test. This value, expressed in percent, is communicated by the manufacturer.
K : normalised reference level
calc
According to the vacuum cleaner under test, the reference cleaning system has to be
equipped with an active or passive nozzle. A separate carpet has to be used for
measurements with active nozzles
6.Z1.2.3 Dust removal ability
The dust removal ability from carpets shall be examined according to 5.3. Different to 5.3.7,
the measurements have to be done and recorded not only after five double strokes but after
each double stroke until the reference level is reached. The fifth double stroke is necessary
for the calculation of the Cleaning Performance index 6.Z1.2.5.
If the normalized reference level is not reached after 10 DS the measurement should be
stopped. In this case the dpu curve has to be extrapolated. If extrapolation does not reach an
, the curve is to be continued by a fix
intersection with the normalized reference level K
calc
slope of 1 % by 50 DS The intersection of the extrapolated curve or of the fix slope line with
the normalized reference level K is the number of DS for the efficiency calculation.
calc
Three separate measurements shall be carried out. Prior to each measurement, the sequence
of preparations outlined in 5.3.3 to 5.3.6 shall be performed in total.
After each double stroke, the cleaning head shall be lifted at least 50 mm clear of the carpet,
and the hose and tubes of the vacuum cleaner shall be agitated before the vacuum cleaner is

switched off. The dust receptacle shall not be removed before the motor has completely
stopped.
Once the cleaner has completely stopped, the receptacle(s) and removable filters are
carefully removed and reweighed. Due to effects of possible static charge build up during the
time the vacuum cleaner is picking up dust, it is necessary to ensure that the receptacle has
completely stabilised prior to recording the weight.
The dust removal ability is calculated as the ratio of the weight increase of the dust receptacle
and removable filters as defined in 4.5 during the single double strokes to the weight of the
test dust distributed on the test area.
The dust removal ability, in per cent, for each double stroke has to be calculated separately
as the mean value from the three measurements according to the following procedure:
for n=1 to 10 and m=1 to 3: D (m,n) = W (m,n)-W (m)
r f i
K (m,n) = D (m,n) / D (m) x 100

With:
W (m) is the weight of the initially empty dust receptacle for
i
each measurement, in grams;
W (m,n) is the weight of the dust receptacle after each double
f
stroke in every measurement in grams;
D (m,n) is the amount of dust removed from the carpet after
r
each double stroke in every measurement, in grams;
D (m) is the amount of dust distributed on the carpet for each
d
measurement, in grams;
K (m,n) is the dust removal ability after each double stroke and
ct
each measurement, in per cent;
K (n) is the mean dust removal from three measurements for
ct
each double stroke, in per cent.
n number of double strokes
m number of measurements
If the range of results for each a single double stroke n is greater than three percentage units,
2 extra measurements shall be made and the mean dust removal ability has to be calculated
as K (n) = (K (1,n) + K (2,n) + K (3,n) + K (4,n) +K (5,n)) / 5

The dust removal ability from hard floor with crevices shall be examined according to 5.2.
Different to 5.2.3 the measurements have to be done and recorded not only after five double
strokes but after each double stroke until the reference level is reached. The fifth double
stroke is necessary for the calculation of the Cleaning Performance index 6.17.3.5
If the reference level is not reached after 10 DS the measurement should be stopped. In this
case the dpu curve has to be extrapolated. If extrapolation does not reach an intersection with
the reference level K , the curve is to be continued by a fix slope of 1 % by 50 DS The
ref
intersection of the extrapolated curve or of the fix slope line with the reference level K is the
ref
number of DS for the efficiency calculation.
Three separate measurements shall be carried out. Prior to each measurement, the sequence
of preparations outlined in 5.2.2 shall be performed in total.
The quantity of dust removed from the crevice after each double strokes is determined as the
difference in weight of the crevice insert before and after the double stroke.

system all loose pile and fibre is removed over the entire surface of the carpet until an amount
2
no greater than 0,5 g/m is removed during the 5 min cleaning process. The weight of the
carpet is recorded.
Using a vacuum cleaner with dust removal ability similar to the reference vacuum cleaner
system, a dust removal test according to 5.3 is carried out and the result recorded and plotted
on a graph. This procedure is repeated until the resulting curve is flat and parallel with the
horizontal axis and the difference between the average results of two consecutive tests is no
greater than
• 1 percentage point for the Wilton carpet and the category C and
• 3 percentage points for the other carpets,
It is once more weighed and the result should be no more than 2 g higher than the weight
recorded after the fibre removal. If so, then further cleaning runs should be made until this
weight is within the 2 g tolerance allowed. This weight is the official carpet weight and is to be
used between tests to minimise dust build up over the life of the carpet. The maximum
allowable deviation from this weight is ± 5 g."
15 Modification to 7.2.1.5
Replace "in house vacuum cleaner" with "reference vacuum cleaner system"
Add after final paragraph:
"In any case the carpet should not to be used for more than 600 cleaning cycles. Then a new
carpet has to be installed."
16 Modification to 7.3.2
Add note before figure:
"NOTE The crevice insert should lay at the same level of rest of the surface used for floor simulation."
