IEC 62301:2011

Household electrical appliances - Measurement of standby power

IEC 62301:2011 specifies methods of measurement of electrical power consumption in standby mode(s) and other low power modes (off mode and network mode), as applicable. It is applicable to electrical products with a rated input voltage or voltage range that lies wholly or partly in the range 100 V a.c. to 250 V a.c. for single phase products and 130 V a.c. to 480 V a.c. for other products. The objective of this standard is to provide a method of test to determine the power consumption of a range of products in relevant low power modes (see 3.4), generally where the product is not in active mode (i.e. not performing a primary function). This standard does not specify safety requirements. It does not specify minimum performance requirements nor does it set maximum limits on power or energy consumption. This second edition cancels and replaces the first edition published in 2005 and constitutes a technical revision. The main changes from the previous edition are as follows:
- greater detail in set-up procedures and introduction of stability requirements for all measurement methods to ensure that results are as representative as possible;
- refinement of measurement uncertainty requirements for power measuring instruments, especially for more difficult loads with high crest factor and/or low power factor;
- updated guidance on product configuration, instrumentation and calculation of measurement uncertainty;
- inclusion of definitions for low power modes as requested by TC59 and use of these new definitions and more rigorous terminology throughout the standard;
- inclusion of specific test conditions where power consumption is affected by ambient illumination.

Appareils électrodomestiques - Mesure de la consommation en veille

La CEI 62301:2011 spécifie les méthodes de mesure de la consommation électrique en mode veille et dans d'autres modes faible puissance (mode arrêt et mode réseau), selon le cas. Elle s'applique aux produits électriques dont la tension assignée ou la plage de tensions est totalement ou partiellement comprise dans la plage de 100 V à 250 V, en courant alternatif, pour les produits monophasés et dans la plage de 130 V à 480 V, en courant alternatif, pour les autres produits. L'objet de cette norme est de fournir une méthode d'essai pour déterminer la consommation d'une gamme de produits dans les modes faible puissance correspondants (voir 3.4), généralement quand le produit n'est pas en mode actif (c'est-à-dire quand il n'effectue pas une fonction principale). La présente norme ne spécifie pas des exigences de sécurité. Elle ne précise pas les exigences d'aptitude à la fonction minimales et ne définit pas non plus les limites maximales de la consommation de puissance ou d'énergie. Cette deuxième édition annule et remplace la première édition parue en 2005, dont elle constitue une révision technique. Les principales modifications par rapport à l'édition précédente sont indiquées ci-après:
- les procédures sont plus détaillées et des exigences de stabilité ont été introduites pour toutes les méthodes de mesures dans le but d'obtenir des résultats aussi représentatifs que possible;
- les lignes directrices relatives à la configuration des produits, aux appareils de mesure et aux calculs des incertitudes de mesure ont été mises à jour;
- des conditions d'essai spécifiques pour les appareils dont la consommation d'énergie est affectée par la luminosité ambiante ont été introduites.

HOUSEHOLD ELECTRICAL APPLIANCES –
MEASUREMENT OF STANDBY POWER
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 62301 has been prepared by IEC technical committee 59:
Performance of household and similar electrical appliances.
This second edition cancels and replaces the first edition published in 2005 and constitutes a
technical revision. The main changes from the previous edition are as follows:
– greater detail in set-up procedures and introduction of stability requirements for all
measurement methods to ensure that results are as representative as possible;
