IEC 63169:2020

Electrical household and similar cooling and freezing appliances - Food preservation

IEC 63169:2020 deals with a test to simulate the weight loss of leafy produce, given certain conditions of temperature, humidity and air movement in one or more test zones. The test can only be applied to spaces larger than 200 mm × 150 mm ×100 mm (L × W × H).
The aim of the test is to measure the weight loss rate by measuring the weight of a test tray prior to the test and after a given duration.
Weight loss is one of the considerations for shelf life of produce. Other considerations such as condensation will be addressed in future amendments.

Appareils électrodomestiques et appareils de refroidissement et de réfrigération analogues - Conservation des aliments

L'IEC 63169:2020 porte sur un essai visant à simuler la perte de poids des légumes feuillus, dans certaines conditions de température, d'humidité et de mouvement de l'air dans une ou plusieurs zone(s) d'essai. L'essai peut uniquement être réalisé dans des espaces de plus de (200 × 150 × 100) mm (L × l × H).
L'essai vise à déterminer le taux de perte de poids en mesurant le poids d'un plateau d'essai avant de procéder à l'essai et après une certaine durée.
La perte de poids est l'une des considérations en matière de durée de conservation des produits. D'autres considérations (la condensation, par exemple) seront traitées dans des amendements à venir.

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 63169 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.
The text of this International Standard is based on the following documents:

NOTE 1 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of
