Replace the existing content with the following new content:
Some of the 500 g packages (50 mm × 100 mm × 100 mm) shall be equipped for temperature
measurement and shall be known as M-packages. These shall be fitted with thermocouples or
other temperature-measuring transducers, which shall be inserted in the geometric centre of the
packages in direct contact with the filling material. All precautions shall be taken to minimize
extraneous conduction of heat. All M-packages located close to the compartment door's gasket
shall be oriented such that the sensor enters the package from the side furthest away from the
door's gasket. The composition and the limitations of their use shall be in accordance with
Clauses C.1 and C.2.D.2 Location of sensors
Replace the existing content with the following new content:
D.2.1 General
The position specified for a temperature sensor is the geometric centre of the sensor (metal
mass), except where minimum clearances are specified, in which case, clearance is to the outer
surface of the metal mass.Temperature sensor positions are specified in the following paragraphs. Clearances or heights
specified are determined from the surface of the compartment at the specified positions. The
surface may be the compartment liner or the surface of a convenience feature or a
sub-compartment. Any fixed feature shall be treated as a surface.The full height of a compartment (h ) is defined as the height at the front of the compartment
or sub-compartment in accordance with D.2.4.2. When the liner at the door seal is curved, the
inner radius shall be taken as reference (see Figure D.6). The full height is used to define the
number of sensors and to classify compartments as small or low-height compartments.
The effective height of a compartment (h), which is used to define the height of sensors in a
compartment, is defined as the height along a vertical line through temperature measurement
point TMP for unfrozen compartments (D.2.2) and TMP for frozen compartments (D.2.3). This
3 14vertical line is defined as the h-line. The measurement is taken from the point where the h-line
reaches the bottom surface of the compartment to the point where the h-line reaches the top
surface of the compartment. Partitions or shelves are ignored when calculating the effective
height. Where the surface of the compartment has a step change (edge) exactly at the h-line,
the surface that is furthest away from the door is used to determine measurements.
NOTE Where the position of TMP or TMP is shifted to meet clearance requirements, the h-line passes through the
3 14new position.
For frozen compartments having a partial width convenience feature where the side gap to
the liner is 100 mm or greater and where the h-line is limited by this convenience feature, the
convenience feature shall be considered not in place for the determination of the h-line.
NOTE This case applies, for example, to ice makers placed inside a frozen compartment, which can be placed on
the left or right top side. As TMP is defined on the right side, this would result in different sensor positions in height
whether the ice maker is placed on the left or the right. Using mirrored positions, as mentioned in D.2.4.1, does not
resolve this inconsistency.Items such as controls and vent housings shall be ignored, as shall other features or protrusions
with a volume of less than 2 l.---------------------- Page: 9 ----------------------

D.2.2 Unfrozen compartments
Except as set out in D.2.4, three air temperature sensors in unfrozen compartments shall be
located at the following vertical positions defined by the h-line (from the bottom):
• at ¾ h (TMP );• at ½ h (TMP );
• at 50 mm (TMP ).
These positions are illustrated in Figure D.1, Figure D.2, Figure D.3 and Figure D.8 a), and with
reference to D.2.4, as applicable.A box evaporator of any shape within an unfrozen compartment where the evaporator is not
configured to provide a separate storage space (i.e. not a sub-compartment) shall be treated
as if it were a convenience feature [see Figure D.2 c)].D.2.3 Frozen compartments
Except as set out in D.2.4, either five or seven air temperature sensors in frozen compartments
shall be located in vertical positions as follows:• two at 50 mm from the top surface of the compartment (TMP front and TMP rear);
12 13
• at ¾ h from the bottom defined by the h-line if h exceeds 1 000 mm (TMP );
1 16
• at ½ h from the bottom defined by the h-line (TMP );
• at ¼ h from the bottom defined by the h-line if h exceeds 1 000 mm (TMP );
1 17
• two at 50 mm from the bottom surface of the compartment (TMP front and TMP rear).
14 15For TMP , TMP , TMP and TMP , the vertical distance is measured at the local position of
12 13 14 15the sensor in the horizontal plane.
Eliminate TMP if the clearance between TMP and TMP is less than 25 mm and eliminate
13 12 13TMP if the clearance between TMP and TMP is less than 25 mm.
15 14 15
These positions are illustrated in Figure D.4, Figure D.5, Figure D.6, Figure D.7 and Figure D.8,
and with reference to D.2.4, as applicable.D.2.4 Equivalent positions and other requirements for all compartment types
D.2.4.1 General
The equivalent sensor locations for special configurations (or features) and other requirements
for all compartment types are set out below.If it is not possible to place sensors in the positions shown in Figures D.1 to D.8, the first option
is to use a mirror image of the positions, as applicable, as illustrated in Figure D.9.
Where it is not possible to place the temperature sensors in one of these positions, they shall be
positioned as near as practicable to the specified locations in a position which will provide an
equivalent result, taking note of the intent above. The position of such locations shall be
recorded in the test report.D.2.4.2 Compartment full height
The full height of a compartment (h ) is defined as the height at the front of the compartment
or sub-compartment adjacent to the door seals from the bottom to the top. When the liner at the
door seal is curved, the inner radius shall be taken as reference (see Figure D.6). For
---------------------- Page: 10 ----------------------IEC 62552-1:2015/AMD1:2020 – 9 –
© IEC 2020
top-opening compartments, the full height is taken from the lowest bottom surface to the gasket
sealing surface.D.2.4.3 Compartment depth
TMP , TMP and TMP for unfrozen compartments, except for small or low-height
1 2 3
compartments, and TMP , TMP and TMP for frozen compartments, shall be located at
11 16 17
the midpoint between the front and back of the compartment at the given vertical position. For
all front opening compartments, the front of the compartment is the gasket sealing surface.
The back of the compartment is defined as the rear surface at the vertical position of the sensor.
D.2.4.4 Compartment widthTMP , TMP and TMP for unfrozen compartments, except for small or low height
1 2 3
compartments, and TMP , TMP and TMP for frozen compartments, shall be located at
11 16 17
the midpoint between the left and right surface of the compartment at the given vertical
position.D.2.4.5 Small compartments, sub-compartments or convenience features
For a compartment/sub-compartment or convenience feature where the full height (h ) of the
compartment/sub-compartment/convenience feature is not more than 150 mm or thevolume is not more than 25 l and where temperature measurements are required, two
temperature sensors shall be used. Each shall be located 50 mm from the lower surface of the
compartment/sub-compartment/convenience feature, one at the front left and the other at
the right rear at d/4 and w/4. Refer to Figure D.3a).D.2.4.6 Low height compartments, sub-compartments or convenience features
For unfrozen compartments, sub-compartments or convenience features where the full
height (h ) is 300 mm or less, and this is less than 0,7 of either the width (measured at the door
sealing surface) or the maximum depth (between the door sealing surface and back wall), the
temperature sensors shall be located in positions as shown in Figure D.3 b). In cases where the
width or depth is greater than 700 mm, the positions shown in Figure D.3 b) shall also be used
if the ratio of full height (h ) to either depth or width is less than 0,6.For frozen compartments where the full height (h ) is 200 mm or less and the volume is 40 l or
less, the temperature sensors shall be located in positions as shown in Figure D.3 b).
D.2.4.7 Clearance from internal fittings (other than shelves)Except where otherwise specified, the clearance of temperature sensors shall be at least 25 mm
from any internal fittings, walls or features. Clearance in this context means the distance from
the surface of the internal fitting, wall or feature to the closest external surface of the
temperature sensor (metal mass).Where a temperature sensor would have less than 25 mm clearance from a fixed
sub-compartment/feature that is not full width, the sensor shall be moved so that the specified
height is maintained while a clearance of 25 mm is maintained from the surface of the
sub-compartment/feature. Where a temperature sensor has to be placed next to aconvenience feature that has a gap on each side, the sensor shall be placed in the gap that is
the larger. Where the gap sizes are equal, the sensor shall be placed in the left gap for sensor
positions that are above the centre of the effective height and on the right gap for sensor
positions that are at or below the centre of the effective height. Refer also to Figure D.1 and
Figure D.2.D.2.4.8 Shelf and temperature sensor placement
The following rules regarding shelf placement shall be applied:
---------------------- Page: 11 ----------------------
– 10 – IEC 62552-1:2015/AMD1:2020
© IEC 2020
• Shelves shall be installed in accordance with the manufacturer's instructions (where
available).• Where no positions are specified in manufacturer instructions, where possible, one shelf in
the largest unfrozen compartment type (where applicable) shall be located belowtemperature sensor position TMP (while maintaining a minimum clearance of 25 mm) and
above TMP , and one shelf shall be located below temperature sensor position TMP (while
2 2maintaining a minimum clearance of 25 mm) and above TMP . As far as possible, any
remaining shelves shall be evenly spaced through the compartment.The following rules regarding temperature sensor placement shall be applied:
• Where the shelves' positions are specified or where there is limited adjustability,
temperature sensors that have less than 25 mm clearance from the shelf shall be relocated
to a position above the shelf with a clearance of 25 mm.• Where a temperature sensor would have less than 50 mm clearance above or below a
refrigerated shelf surface, or any evaporator surface (such as plate or box evaporator) that
temperature sensor shall be relocated to a position with 50 mm clearance above the relevant
refrigerated shelf, where possible, and shall maintain 50 mm clearance in all horizontal
directions.Door shelves, drawers, bins, sliding baskets or items with dedicated but interchangeable
positions shall all be kept in place but organised to minimise their interference with temperature
sensors.Items which are not intended to be in place during normal use, as specified in the instructions,
are removed.D.2.4.9 Convenience feature and temperature sensor placement
Where a convenience feature interferes with the position of a temperature sensor, the same
rules as for part width compartments (see D.2.4.7) and for shelves (see D.2.4.8) apply. If the
sensor in the compartment lies in the convenience feature, it shall be moved to the nearest
position outside it.D.2.4.10 Frozen compartment sensors and door shelves
Where a deep door shelf interferes with or encloses the location for sensor positions TMP or
TMP , (refer to Figure D.5 and Figure D.6) or the air space clearance is less than 25 mm, then
the centre line of the sensor shall be moved by up to 50 mm further into the compartment
(i.e. a maximum depth of 150 mm from the door gasket) in order to satisfy the clearance. If this
does not satisfy the requirements, the sensor shall be located inside the door shelf as close as
possible to the original position while maintaining a clearance of 30 mm from the centre of the
sensor to the wall and 50 mm from the centre of the sensor to the floor of the door shelf.
Where a two-star section only comprises door shelves, three sensors shall be positioned
diagonally, similar to the low-height compartments (see Figure D.3b). The h-line is to be
determined from the bottom surface of the two-star section to the top surface using TMP as
reference. In the absence of top and/or bottom surfaces, the door or volume borders (see
IEC 62552-3:2015/AMD1:2020, Clause H.4) shall be taken as the limit for the h-line and sensor
positions. The sensor positions shall be:• TMP at 50 mm from the top surface;
• TMP at ½ h defined by the h-line;
• TMP at 50 mm from the bottom surface.
The sensor positions shall be in width direction (if these positions are not available, the sensors
shall be shifted to the nearest position at the given height level that maintains minimum
clearances):---------------------- Page: 12 ----------------------
IEC 62552-1:2015/AMD1:2020 – 11 –

• TMP at 50 mm from the section border closest to the hinge;
• TMP at the midpoint measured at the height level ½ h;
• TMP at 50 mm from the section border at the opposite side from TMP .
23 21
In the depth direction, the three sensors shall be placed at the midpoint where the depth is
measured from the door surface to the volume border, this for each sensor at its corresponding
height level.If a three-star or four-star compartment has multiple doors, a two-star section contained in it
shall not cover multiple doors. If required, a two-star section can be defined in each door.
