A.3.2.3 Temperature values
Replace item a) with:
a) For assessing the storage temperatures:
+10 °C and +32 °C for class SN refrigerating appliances;
+16 °C and +32 °C for class N refrigerating appliances;
+16 °C and +38 °C for class ST refrigerating appliances;
+16 °C and +43 °C for class T refrigerating appliances.
For products rated for multiple climate classes, tests only need to be performed at the extreme
ambient temperatures of all the relevant rated classes. Testing details are specified in
Clause 6 of IEC 62552-2:2015 and IEC 62552-2:2015/AMD1:2020.
EXAMPLE For refrigerating appliances rated from SN to T, tests are performed at +10 °C and at +43 °C
In addition, verification tests may be carried out at any ambient temperature between the
minimum and maximum temperature defined by the climate class in order to confirm compliance
with the storage temperature requirements at any ambient temperature.
Replace item c) with:
– 6 – IEC 62552-1:2015/AMD1:2020
© IEC 2020
c) For assessing the temperature rise time, freezing capacity, cooling capacity and
automatic ice-making capacity of all refrigerating appliances, as applicable and specified
in Clauses 7 to 9 and Annex C of IEC 62552-2:2015 and IEC 62552-2:2015/AMD1:2020:
+25 °C for all classifications of refrigerating appliances;
Replace item d) with:
d) For assessing the pull-down performance test as specified in Annex A of
IEC 62552-2:2015:
at the maximum ambient temperature in accordance with the climate class specified;
B.2.5.2 Variable temperature compartments
Replace the content with the following new content:
Where the compartment is a variable temperature compartment type (that spans the
operating range of several compartment types), it shall be classified.
a) For the storage test (IEC 62552-2): each variable temperature compartment shall be
capable of maintaining specified internal temperatures for each claimed compartment type
at ambient temperatures across the rated range.
b) For the cooling capacity test (IEC 62552-2): if the variable temperature compartment
can be used as a fresh food compartment, it shall be operated as a fresh food
compartment type where this test is performed.
c) For the freezing capacity and temperature rise time tests (IEC 62552-2): if the variable
temperature compartment can be used as a three-star or four-star compartment, it shall
be operated as a three-star or four-star compartment type where this test is performed.
d) For the energy consumption, water vapour condensation and ice-making capacity tests
(IEC 62552-2 and IEC 62552-3), as applicable: the variable temperature compartment
shall operate as the compartment type which has the highest energy consumption for the
energy test.
Additional requirements regarding each compartment type are specified in IEC 62552-3:2015,
Table 1 during the energy consumption test. In the energy consumption test, where a
refrigerating appliance has variable temperature compartments that can operate as more
than one compartment type, additional compartment classifications may be tested, if required,
in addition to the primary classification specified above.
C.1 Dimensions and tolerances
Add a note after the second paragraph:
NOTE In IEC 62552:2007, 1 kg packs were defined (200 mm × 100 mm × 50 mm) that can be reused under this
document by combining 2 packages vertically to form stacks with a footprint of 100 mm × 100 mm.
C.2 Composition
Replace the second paragraph of item c) with
