IEC 62552-2:2015

Household refrigerating appliances - Characteristics and test methods - Part 2: Performance requirements

IEC 62552-2:2015 specifies the essential characteristics of household refrigerating appliances cooled by internal natural convection or forced air circulation, and specifies test methods for checking the characteristics. This part of IEC 62552 describes the methods for the determination of performance requirements. Although there is some commonality in the set-ups for different tests (and so it may be an advantage to apply them all to one sample), these are separate tests to evaluate specific characteristics of the sample being tested. This part of IEC 62552 does not specify a procedure to generalise the results from sample test results to a prediction of the characteristics of the whole population from which that sample was selected. IEC 62552-1, IEC 62552-2 and IEC 62552-3 cancel and replace the first edition of IEC 62552 published in 2007. IEC 62552-1, IEC 62552-2 and IEC 62552-3 together constitute a technical revision and include the following significant technical changes with respect to IEC 62552:2007:
- A cooling capacity test has been added in Part 2 (this part).
- A pull-down test has been added in Part 2 (this part).
- Performance tests have been added for wine storage appliances in Part 2 (this part).

Appareils de réfrigération à usage ménager - Caractéristiques et méthodes d'essai - Partie 2: Exigences de performances

L'IEC 62552-2:2015 spécifie les caractéristiques essentielles des appareils de réfrigération à usage ménager refroidis par convection naturelle interne ou par circulation d'air forcé, et spécifie les méthodes d'essai pour la vérification des caractéristiques. La présente partie de l'IEC 62552 décrit les méthodes de détermination des exigences de performances. Même si les montages présentent certaines similitudes pour les différents essais (et qu'il peut donc s'avérer avantageux de les appliquer à un seul échantillon), il s'agit d'essais distincts permettant d'évaluer les caractéristiques spécifiques de l'échantillon en essai. La présente partie de l'IEC 62552 ne spécifie pas de procédure visant à généraliser les résultats d'essai sur échantillon à une prédiction des caractéristiques de l'ensemble de la population à partir de laquelle ces échantillons ont été sélectionnés. 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:
- Un essai de capacité de refroidissement a été ajouté dans la Partie 2 (la présente partie).
- Un essai de mise en régime a été ajouté dans la Partie 2 (la présente partie).
- Des essais de performance ont été ajoutés pour les appareils de stockage du vin dans la Partie 2 (la présente partie).

Part 2: Performance requirements
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62552-2 has been prepared by subcommittee 59M: Performance

of electrical household and similar cooling and freezing appliances, of IEC technical

committee 59: Performance of household and similar electrical appliances

IEC 62552-1, IEC 62552-2 and IEC 62552-3 cancel and replace the first edition of IEC 62552

published in 2007. IEC 62552-1, IEC 62552-2 and IEC 62552-3 together constitute a technical

revision and include 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 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.
---------------------- Page: 7 ----------------------
– 6 – IEC 62552-2:2015 © IEC 2015

c) For more efficient analysis and to better characterise the key product characteristics

under different operating conditions, the test data from many of the energy tests in Part 3

is now split into components (such as steady state operation and defrost and recovery).

The approach to determination of energy consumption has been completely revised, with

many internal checks now included to ensure that data complying with the requirements of

the standard is as accurate as possible and of high quality.

d) Part 3 of the standard now provides a method to quantify each of the relevant energy

components and approaches on how these can be combined to estimate energy under

different conditions on the expectation that different regions will select components and

weightings that are most applicable when setting both their local performance and energy

efficiency criteria while using a single set of global test measurements.

e) For energy consumption measurements in Part 3, no thermal mass (test packages) is

included in any compartment and compartment temperatures are based on the average of

air temperature sensors (compared to the temperature in the warmest test package).

There are also significant differences in the position of temperature sensors in unfrozen

compartments.

f) The energy consumption test in Part 3 now has two specified ambient temperatures (16°C

and 32°C).

g) While, in Part 2 (this part) test packages are still used for the storage test to confirm

performance in different operating conditions, in Part 1 they have been standardised to

one size (100 mm × 100 mm × 50 mm) to simply loading and reduce test variability. A

clearance of at least 15 mm is now specified between test packages and the compartment

liner.
h) A load processing energy efficiency test has been added in Part 3.
i) A tank-type ice making energy efficiency test has been added in Part 3.
j) A cooling capacity test has been added in Part 2 (this part).
k) A pull-down test has been added in Part 2 (this part).

l) Shelf area and storage volume measurement methods are no longer included. In Part 3

the volume measurement has been revised to be the total internal volume with only

components necessary for the satisfactory operation of the refrigeration system
considered as being in place.

m) Tests (both performance (Part 2 – this part) and energy (Part 3)) have been added for

wine storage appliances.
The following print types are used in this international standard:
– requirements: in roman type;
– test variables: in italic type;
– notes: in small roman type.
– words in bold are defined in IEC 62552-1:2015.
The text of this standard is based on the following documents:
