MEASUREMENT OF ENERGY CONSUMPTION
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 62623 has been prepared by IEC technical committee 108: Safety
of electronic equipment within the field of audio/video, information technology and
communication technology.
This standard is based on ECMA-383.
The text of this standard is based on the following documents:

INTRODUCTION
This standard is based on ECMA-383 and complements the guidance given in IEC 62075. It
includes the definitions of energy saving modes and generic energy saving guidance for
designers of desktop and notebook computers, by defining a methodology on how to measure
the energy consumption of a product whilst providing categorisation criteria that enable
energy consumption comparisons of similar products.

DESKTOP AND NOTEBOOK COMPUTERS –
MEASUREMENT OF ENERGY CONSUMPTION
1 Scope
This International Standard covers personal computing products. It applies to desktop and
notebook computers as defined in 4.1 that are marketed as final products and that are
hereafter referred to as the equipment under test (EUT) or product.
This standard specifies:
– a test procedure to enable the measurement of the power and/or energy consumption in
each of the EUT's power modes;
– formulas for calculating the typical energy consumption (TEC) for a given period
(normally annual);
– a majority profile that should be used with this standard which enables conversion of
average power into energy within the TEC formulas;
– a system of categorisation enabling like for like comparisons of energy consumption
between EUTs;
– a pre-defined format for the presentation of results.
This standard does not set any pass/fail criteria for the EUTs. Users of the test results should
define such criteria.
