8 Freezing capacity test
Replace Clause 8 with the following new content:
8 Freezing capacity test
8.1 Objective
The purpose of this test is to measure the freezing capacity of freezer compartment(s) by
adding warm test packages (the light load) into the compartment. If the freezing capacity is
greater than, or equal to, the specified minimum capacity (see 8.4.3), the compartment(s) may
be rated as a four-star compartment(s).
8.2 Method overview
Apart from space for the light load, ballast packages are loaded into the frozen
compartment(s) as for the storage test (Clause 6). The refrigerating appliance is operated
until temperatures are stable and in compliance with Table 2. Then a load of packages at
+25 °C is added. This is the so-called light load representing a food load to be processed. The
time to freeze this load to −18 °C is measured. When this can be achieved in no more than 24 h
and other maximum temperature-excursion conditions are met, a four-star compartment
rating may be claimed
NOTE Because the frozen compartment loading is largely the same as for the storage test, there can be an
advantage in doing these tests consecutively.
8.3 Set-up procedure
8.3.1 Ambient temperature
The ambient temperature shall be 25 °C (see A.3.2.3 of IEC 62552-1:2015).

© IEC 2020
8.3.2 Preparation of the refrigerating appliance
8.3.2.1 General
The refrigerating appliance shall be installed in accordance with Annex B of
IEC 62552-1:2015.
If the configuration of the refrigerating appliance can be changed by the user, the
configuration with the greatest volume at the lowest temperatures shall be used for this test.
Refrigerating appliances with anti-condensation heater(s) which are permanently on during
normal use shall be tested with the heater(s) operating.
Anti-condensation heaters which can be manually controlled by the user shall be switched on
and, if adjustable, they shall be set at their maximum heating rate.
Anti-condensation heaters which are automatically controlled shall be allowed to operate
normally.
Thermal storage devices shall be placed in the dedicated positions in the respective
compartments, in accordance with the manufacturer's instructions, and shall be independent
of the location of the test packages. Instructions for loose placement of thermal storage devices
in the appliance do not define dedicated positions.
NOTE Instructions without specific indication of location or placement of the thermal storage devices is an example
of loose placement.
If dedicated positions are absent, the thermal storage devices shall be removed from the
compartment.
The unloaded refrigerating appliance should be set up and operated until it has reached
equilibrium at, or close to, the temperatures specified in Table 2.
8.3.2.2 Measurement of temperature of chill compartment and all compartments
operating above 0 °C
During the test, the chill compartment temperature is not measured, but it shall be loaded with
test packages as for the storage temperature measurement (see 6.3.2). For determining the
storage temperature of the compartments normally operating above 0 °C, measurement
points shall be as per Annex D of IEC 62552-1:2015 and IEC 62552-1:2015/AMD1:2020, but
with M-packages used instead of cylinders.
8.3.3 Loading of refrigerating appliance
8.3.3.1 Frozen compartment(s) – ballast load
8.3.3.1.1 General
Apart from space for the light load in the appropriate −18 °C compartment(s), ballast
packages are brought to the approximate compartment temperatures and loaded into the
frozen compartment(s), as for the storage test (Clause 6).
A load stack can be comprised of one or more load packages.
In the −18 °C compartment(s), ballast load may be removed to accommodate the light load.
Light load positioning shall take into account the instructions regarding the location to be used
for freezing. If no instructions are given, the packages shall be placed such that they are likely
to be frozen as rapidly as possible.

– 10 – IEC 62552-2:2015/AMD1:2020
© IEC 2020
Furthermore, the following constraints shall be fulfilled:
a) the minimum number of stacks shall be removed;
b) the height of a light load stack shall be 2 packages, with the following exceptions:
1) if the light load is to be composed of an odd number of packages, then one light load
stack of 1 package is allowed;
2) if the ballast load to be removed only exists out of stacks of 1 package, then it is
allowed to replace these by light load stacks of 1 package;
3) if the ballast load stack to be removed contains 6 or more packages, then it shall be
replaced with a light load stack of half the number of packages in the ballast load
stack (rounded down).
c) the minimum ballast load is 1 M-package;
d) light load packages shall be placed flat;
e) light load positioning shall take into account the instructions regarding the location to be
used for freezing. If no instructions are given, the packages shall be placed such that they
are likely to be frozen as rapidly as possible;
f) light load packages shall be separated by at least 15 mm from ballast load packages. The
use of spacers between adjacent stacks of packages is permitted, but other spacing
methods are not (see 6.3.3.2).
8.3.3.1.2 M-package placement in the ballast load to accommodate the light load
The M-packages in the ballast load shall be placed in the same manner as for the storage test,
apart from in any locations that are disrupted by the need to leave space for the light load. In
that case, the M-packages shall be placed in the nearest equivalent position to that specified
for the storage test and the new positions recorded. If there are stacks of ballast load
packages beside the light load, an M-package shall also replace the top test package in at
least one of those stacks on each side of the light load. If there is ballast load above the light
load, an M-package shall replace a test package in the centre of the layer immediately above
the light load. If there is ballast load below the light load, an M-package may replace a test
package in the centre of the layer immediately below the light load.
8.3.3.2 Refrigerating appliances with separate three-star compartment
If a refrigerating appliance has a separate three-star compartment with its own external
access door or lid, and the instructions recommend that, before freezing, frozen food already in
storage be placed in that compartment while leaving space in the freezer compartment to
receive the load for freezing (i.e. the three-star compartment is to be regarded as an
extension of the freezer compartment), a freezing time claim based upon this method of use
is permissible, provided that:
a) when tested according to this method of use, the claimed freezing time is confirmed and
the temperature requirements for the other compartments (see 8.5 a) to g)), if applicable,
are fulfilled during the freezing capacity test, and
b) the light load used in the freezer compartment is at least equivalent to 3,5 kg/100 l of the
combined volumes of the freezer compartment and three-star compartment.
8.4 Test procedure
8.4.1 Starting conditions
After all relevant control devices have been adjusted as required, the loaded refrigerating
appliance is left to run until stable operating conditions are reached.
After stable operating conditions have been attained, internal temperature(s) shall be in
accordance with Table 2, except that the starting temperature of any compartment(s) with no
lower temperature limit(s) specified in that table shall be no more than 2 K below the target
temperature.
© IEC 2020
In the case of a refrigerating appliance where the compartment temperatures cannot be
adjusted independently, if such a setting is not possible, the non-complying compartments
below the bottom limit shall be set to be as warm as possible.
The temperature indication succession from left to right in Table 2 also indicates the order of
precedence in the case of several temperature possibilities.
In some circumstances, it might be unnecessary to carry out the stabilisation specified here
before the stabilisation specified in 8.4.2.
8.4.2 Setting of control devices
If the refrigerating appliance is provided with means for a pre-freezing (fast-freezing or
quick-freezing) operation, after stable operating conditions in accordance with 8.4.1 have
been attained, the refrigerating appliance shall be set in operation in the pre-freezing
condition according to the instructions. The procedure specified in 8.4.3 shall then be carried
out.
If there are no special instructions for pre-freezing, the procedure described in 8.4.3 shall be
carried out after the refrigerating appliance has reached stable operating conditions in
accordance with the temperature requirements of 8.4.1.
8.4.3 Freezing of the light load
After the conditions specified in 8.4.2 have been attained, the light load shall be introduced.
For models with defrost control cycles, the light load should be added when stability has
been regained and temperature criteria met after a defrost and recovery period. This test
should not overlap a defrost and recovery period. When stability has been achieved prior to
the introduction of the light load, apart from as in 8.4.2, changes of setting of manually
adjustable controls are no longer permitted.
The light load shall be 3,5 kg/100 l of the total volume of all compartments operating at
−18 °C (three and four stars). The calculated load shall be rounded up to the nearest 0,5 kg,
except that in no case shall it be less than 2,0 kg.
The light load is made from packages which have previously been brought to a temperature of
+25 °C ± 1 K.
M-packages shall be uniformly distributed throughout the light load with at least one as close
as practicable to its geometric centre. The number of M-packages to apply is given in Table 5.

8.4.4 Intermediate test data to be recorded
The temperatures of the M-packages in the ballast load and in the light load shall be recorded,
together with those of the M-packages in the other compartment(s), if any. This shall be done
until the arithmetic mean of the instantaneous temperatures of all the M-packages in the light

– 12 – IEC 62552-2:2015/AMD1:2020
© IEC 2020
load reaches ≤ −18 °C and all other criteria in 8.5 are satisfied. The time necessary for
reaching this condition shall be recorded as the freezing time.
If, during the test, an M-package exhibits a supercooling effect, the test is invalid and shall be
repeated, possibly with a replaced M-package.
Supercooling, also known as undercooling, is the process of lowering the temperature of a
liquid below its freezing point without it becoming a solid. It can be observed during the test as
a rapid increase of the temperature in an M-package. If the increase is more than 3 K, the test
shall be considered invalid.
8.5 Criteria to achieve a four-star compartment rating
A compartment achieves a four-star rating if the arithmetic mean of the instantaneous
temperatures of all the M-packages in the light load reaches ≤ −18 °C in no more than 24 h
and:
a) unless a defrost and recovery period overlaps the test, the maximum temperature of any
M-packages of the ballast load remains ≤ −15 °C and at the end of the test the maximum
temperature of the warmest M-package of the ballast load is ≤ −18 °C;
b) if a defrost and recovery period does overlap the test, the maximum temperature of any
M-packages of the ballast load remains ≤ −12 °C during the defrost and recovery period
and at the end of the test the maximum temperature of the warmest M-package of the
ballast load is ≤ −18 °C;
c) the maximum temperature of the warmest M-package in any separate three-star
compartment not used for ballast in accordance with 8.3.3.2 remains ≤ −18 °C (plus the
allowed excursions during any defrost and recovery period as specified in Table 2);
d) the maximum temperature of the warmest M-package in any two-star section or two-star
compartment remains ≤ −12 °C (plus the allowed excursions during a defrost and
recovery period as specified in Table 2);
e) the maximum temperature of the warmest M-package in any one-star compartment
remains ≤ −6 °C;
