Household refrigerating appliances - Characteristics and test methods - Part 1: General requirements

IEC 62552-1:2015 specifies the essential characteristics of household refrigerating appliances, cooled by internal natural convection or forced air circulation, and establishes test methods for checking the characteristics. For the purposes of declaration, the tests defined in this part of IEC 62552 are considered to be type tests to assess the fundamental design and operation of a refrigerating appliance. This part of IEC 62552 does not define requirements for production sampling or conformity assessment or certification. This part of IEC 62552 does not define a regime for verification testing as this varies by region and country. When verification of the performance of a refrigerating appliance of a given type in relation to this standard is necessary, it is preferable, wherever practicable, that all the tests specified be applied to a single unit. The tests can also be made individually for the study of a particular characteristic. IEC 62552-1, -2 and -3 cancel and replace the first edition of IEC 62552 published in 2007. IEC 62552-1, -2 and -3 constitute a technical revision and includes the following significant technical changes with respect to IEC 62552:2007: a) All parts of the standard have been largely rewritten and updated to cope with new testing requirements, new product configurations, the advent of electronic product controls and computer based test-room data collection and processing equipment. b) In Part 1 (this part) there are some changes to test room equipment specifications and the setup for testing to provide additional flexibility especially when testing multiple appliances in a single test room.

Haushaltskühlgeräte - Eigenschaften und Prüfverfahren - Teil 1: Allgemeine Anforderungen

Appareils de réfrigération à usage ménager - Caractéristiques et méthodes d'essai - Partie 1: Exigences générales

L'IEC 62552-1:2015 spécifie les caractéristiques essentielles des appareils de réfrigération à usage ménager, refroidis par convection naturelle interne ou par circulation d'air forcé, et établit les méthodes d'essai pour la vérification des caractéristiques. Pour les besoins de la déclaration, les essais définis dans la présente partie de l'IEC 62552 sont considérés comme étant des essais de type visant à évaluer la conception et le fonctionnement de base d'un appareil de réfrigération. La présente partie de l'IEC 62552 ne définit pas les exigences en matière d'échantillonnage de production ou d'évaluation ou de certification de la conformité. La présente partie de l'IEC 62552 ne définit pas le régime d'essais de vérification, lesquels varient selon la région et le pays. Lorsqu'il est nécessaire de vérifier les performances d'un appareil de réfrigération d'un type donné, en liaison avec la présente Norme internationale, il est préférable, dans la mesure du possible, que tous les essais spécifiés soient appliqués à un seul appareil. Ces essais peuvent être également effectués séparément pour l'étude d'une caractéristique particulière. L'IEC 62552-1, l'IEC 62552-2 et l'IEC 62552-3 annulent et remplacent la première édition de l'IEC 62552 publiée en 2007. L IEC 62552-1, l'IEC 62552-2 et l'IEC 62552-3 constituent une révision technique et incluent les modifications techniques suivantes par rapport à l'IEC 62552:2007: a) Toutes les parties de la norme ont été largement réécrites et mises à jour pour tenir compte des nouvelles exigences d'essai, des nouvelles configurations du produit, de l'apparition de nouvelles commandes de produit électronique et d'équipements informatiques de collecte et de traitement de données de salle d'essai. b) Dans la Partie 1 (la présente partie) les modifications ont été apportées aux spécifications en matière d'équipement de salle d'essai, ainsi qu'au montage d'essai, afin d'apporter une souplesse supplémentaire, plus particulièrement lors des essais de plusieurs appareils dans une seule salle d'essai.

"for low noise refrigerating appliance energy consumption test shall be done at 25 °C"

Delete subclause A.3.4 and renumber the following subclauses.
5 Modifications to Annex B, “Preparation of an appliance for testing and general
measurement procedure”
In B.2.3.3, "Built-in appliances", replace the sixth paragraph with:

"The depth of niche used for test shall be an integer multiple of 20 mm and the smallest value that equals or

exceeds the minimum dimension specified by the manufacturer. If a single specific dimension is given, this

dimension shall be used for testing.

NOTE Z1 The most common depth of niche for furniture is 560mm. If the manufacturer declare the range from 550 mm

to 570 mm, the dimension for the testing is 560 mm. If the manufacturer declare the range from 560 mm to 580 mm, the

dimension for the testing is 560 mm.

If these dimensions are not given or is declared only the maximum value of range, the inner dimensions of

the test enclosure shall be as follows:

• the inner depth shall exceed by 0 mm to 2 mm the overall depth of the refrigerating appliance;

• the inner width shall exceed by 4 mm to 6 mm the overall width of the refrigerating appliance;

"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 (EN 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.
---------------------- Page: 9 ----------------------
SIST EN 62552-1:2020
EN 62552-1:2020

b) For the cooling capacity test (EN 62552-2): If the variable temperature compartment can be used as

a fresh food compartment, it shall be operated as fresh food compartment type where this test is

performed.

c) For the freezing capacity and temperature rise time test (EN 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 test (EN 62552-2

and EN 62552-3), as applicable.

Additional requirements regarding each compartment type are specified in EN 62552-3, 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."
6 Modifications to Annex C, “Test Packages”
In C.1, "Dimensions and tolerances", add the following note:

"Note Z1 In EN 62552:2007, 1 kg packs were defined (200 mm x 100 mm x 50 mm) which can be reused under this

standard by combining 2 packages vertically to form stacks with a footprint of 100 mm x 100 mm."

In C.2, "Composition", replace the second paragraph in c) with:
"Where test packages are required, packages of type a) or b) can be used except:

"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

---------------------- Page: 10 ----------------------
SIST EN 62552-1:2020
EN 62552-1:2020 (E)

transducers which shall be inserted in the geometrical 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 gasket, shall be oriented such that the sensor enters the package from the

side furthest away from the door gasket. The composition and the limitations of their use shall be in

accordance with Clauses C.1 and C.2."
7 Modifications to Annex D, “Determination of compartment average air
temperatures”
Replace the entire subclause D.2 "Location sensors" with:
"D.2.1 Location of sensors

The positions 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 according 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 TMP3 for unfrozen

compartments (D.2.2) and TMP14 for frozen compartments (D.2.3). This 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 Z1 Where the position of TMP3 or TMP14 is shifted to meet clearance requirements the h-line passes through

the 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 Z2 This case applies to e.g. ice makers placed inside a frozen compartment, which can be placed on the left or

right top side. As TMP14 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 Clause D.2.4.1 does not resolve this

inconsistency.
---------------------- Page: 11 ----------------------
SIST EN 62552-1:2020
EN 62552-1:2020

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 3/4 h (TMP1);
• at 1/2 h (TMP2);
• 50 mm (TMP3).

These positions are illustrated in Figure D.1, Figure D.2, and Figure D.3 and Figure D.8 part 1 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 is a convenience

feature (see Figure D.2.Part 3).
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 (TMP12 front and TMP13 rear);

• at 3/4 h from the bottom defined by the h-line if h1 exceeds 1000 mm (TMP16);
• at 1/2 h from the bottom defined by the h-line (TMP11);
• at 1/4 h from the bottom defined by the h-line if h1 exceeds 1000 mm (TMP17);

• two at 50 mm from the bottom surface of the compartment (TMP14 front and TMP15 rear).

For TMP12, TMP13, TMP14 and TMP15, the vertical distance is measured at the local position of the sensor

in the horizontal plane.

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.
---------------------- Page: 12 ----------------------
SIST EN 62552-1:2020
EN 62552-1:2020 (E)

Where it is not possible to place the temperature sensors in either 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 top opening compartments the full

height is taken from the lowest bottom surface to the gasket sealing surface.
D.2.4.3 Compartment depth

TMP1, TMP2 and TMP3 for unfrozen compartments, except for small or low height compartments, and

TMP11, TMP16 and TMP17 for frozen compartments, shall be located at 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

TMP1, TMP2 and TMP3 for unfrozen compartments, except for small or low height compartments, and

TMP11, TMP16 and TMP17 for frozen compartments, shall be located at the midpoint between the left and

right surface of the compartment at the given vertical position.
D.2.4.5 Small compartments/small sub-compartments

For a compartment/sub-compartment or convenience feature where the full height (h ) of the

compartment/sub-compartment 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 sub-compartment, 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

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).

---------------------- Page: 13 ----------------------
SIST EN 62552-1:2020
EN 62552-1:2020

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 shall

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. Also refer 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:

1. Shelves shall be installed in accordance with manufacturer instructions (where available)

2. 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

TMP1 (while maintaining a minimum clearance of 25 mm) and above TMP2 and one shelf shall be

located below temperature sensor position TMP2 (while maintaining a minimum clearance of 25 mm) and

above TMP3. As far as possible, any remaining shelves shall be evenly spaced through the

compartment.
The following rules regarding temperature sensor placement shall be applied:

1. Where 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.

2. 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 organized to minimize 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 in D.2.4.7 and for shelves, 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 TMP12 or TMP14, (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 of 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 TMP23 as reference. In the absence of top and/or

bottom surfaces, the door or volume borders (see EN 62552:3 Amendment 1 Annex H.4) shall be taken as

the limit for the h-line and sensor positions. The sensor positions shall be:
• TMP21 at 50 mm from
