3) For one-star compartments, only packages a) shall be used.
4) For the temperature rise time test, only packages a) shall be used.
C.3 M-packages
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 14

vertical 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 14
new 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.

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 15

For TMP , TMP , TMP and TMP , the vertical distance is measured at the local position of

12 13 14 15
the sensor in the horizontal plane.

Eliminate TMP if the clearance between TMP and TMP is less than 25 mm and eliminate

13 12 13
TMP 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 width
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 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 the

volume 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 a

convenience 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 below

temperature 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 2

maintaining 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 –
© IEC 2020
• 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.
