Audio, video and related equipment - Methods of measurement for power consumption - Part 7: Computer monitors
IEC 62087-7:2018 specifies the determination of the power consumption of computer monitors including, but is not limited to, those with CRT, LCD, PDP or OLED technologies. Computer monitors that include touch screen functionality are included in the scope of this document. This document is limited to computer monitors that are powered from a main power source other than a battery. Computer monitors that are powered from a battery source are not covered by this document. However mains-powered computer monitors may include any number of auxiliary batteries.
Computer monitors connected by digital inputs such as DisplayPort, HDMI, DVI, or by analogue VGA input, are considered in this document. This document does not apply to network- and wirelessly connected computer monitors.
A computer monitor is a display device that does not include a TV tuner and is intended to be used to display the video signals from a computer. These video signals are produced from software programs that are operating within the computer and can consist of static and moving images. As such, test procedures using static patterns, dynamic video and web-based video are specified.
The test methods specified in this document can be applied to computer monitors of any size, however, this document is not applicable to specialized monitors associated with medical equipment, publishing and other professional, commercial or industrial uses.
The various modes of operation that are relevant for measuring power consumption are also defined.
The measuring conditions in this document represent the normal use of the equipment and can differ from specific conditions, for example as specified in safety standards.
Appareils audio, vidéo et matériel connexe – Méthodes de mesure de la consommation de puissance - Partie 7 : Moniteurs d'ordinateurs
L'IEC 62087-7:2018 spécifie la détermination de la consommation de puissance des moniteurs d'ordinateurs, et notamment de ceux qui utilisent les technologies CRT, LCD, PDP ou OLED. Les moniteurs d'ordinateurs qui disposent d'une fonctionnalité d'écran tactile sont inclus dans le domaine d'application du présent document. Le présent document ne traite que des moniteurs d'ordinateurs alimentés en électricité par une source d'énergie principale autre qu'une batterie. Les moniteurs d'ordinateurs alimentés par batterie ne sont pas couverts par le présent document. Les moniteurs d'ordinateurs alimentés sur secteur peuvent toutefois comprendre un certain nombre de batteries auxiliaires.
Les moniteurs d'ordinateurs connectés par le biais d'entrées numériques de type DisplayPort, HDMI ou DVI, par exemple, ou au moyen d'une entrée VGA analogique, sont traités dans le présent document. Le présent document ne s'applique pas aux moniteurs d'ordinateurs connectés en réseau et sans fil.
Un moniteur d'ordinateur est un dispositif d'affichage qui ne comporte pas de récepteur TV et qui est destiné à être utilisé pour afficher les signaux vidéo à partir d'un ordinateur. Ces signaux vidéo sont produits par des logiciels informatiques exécutés sur l'ordinateur et peuvent être constitués d'images fixes et mobiles. A ce titre, les procédures d'essai qui utilisent des modèles statiques, la vidéo dynamique et la vidéo sur le Web sont spécifiées.
Les méthodes d'essai spécifiées dans le présent document peuvent être appliquées à tous les moniteurs d'ordinateurs, quelle que soit leur taille. En revanche, le présent document ne s'applique pas aux moniteurs spéciaux liés au matériel médical, à l'édition et à d'autres utilisations professionnelles, commerciales ou industrielles.
Les différents modes de fonctionnement adaptés au mesurage de la consommation de puissance sont également définis.
Les conditions de mesure du présent document sont représentatives de l'usage normal du matériel et peuvent différer des conditions particulières, comme celles spécifiées dans les normes de sécurité.

METHODS OF MEASUREMENT FOR POWER CONSUMPTION
Part 7: Computer monitors
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 inde
