Audio, video, and related equipment - Methods of measurement for power consumption Part 7: Computer monitors
This part of IEC 62087 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 d’énergie - Partie 7 : Écrans d’ordinateur
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.
Avdio, video in pripadajoča oprema - Metode za merjenje porabe energije - 7. del: Računalniški zasloni (IEC 62087-7:2018)
Ta del standarda IEC 62087 določa način ugotavljanja porabe energije računalniških monitorjev, med drugim monitorjev s tehnologijami CRT, LCD, PDP ali OLED, vendar ne omejeno nanje. Računalniški monitorji s funkcijo zaslona na dotik so vključeni na področje uporabe tega dokumenta. Ta dokument je omejen na računalniške monitorje, ki se napajajo iz glavnega vira energije, ki ni baterija. Dokument ne zajema računalniških monitorjev, ki se napajajo iz baterij. Vendar lahko računalniški monitorji, ki se napajajo iz električnega omrežja, vsebujejo poljubno število pomožnih baterij.
V tem dokumentu so upoštevani računalniški monitorji, povezani z digitalnimi vhodi, kot so DisplayPort, HDMI, DVI ali analogni vhod VGA. Ta dokument se ne uporablja za omrežne in brezžično povezane računalniške monitorje.
Računalniški monitor je prikazovalna naprava, ki ne vsebuje TV-kartice in je namenjena za prikaz video signalov iz računalnika. Te video signale ustvarijo aplikacije programske opreme, ki delujejo v računalniku, signali pa so lahko sestavljeni iz statičnih in premikajočih se slik. Tako so preskusni postopki določeni z uporabo statičnih vzorcev, dinamičnega videa in spletnega videa.
Preskusne metode, določene v tem dokumentu, je mogoče uporabiti za računalniške monitorje poljubne velikosti, vendar dokument se ne uporablja za specializirane monitorje, povezane z medicinsko opremo ali založništvom, in za druge profesionalne, komercialne ali industrijske namene.
Opredeljeni so tudi načini delovanja, ki so pomembni za merjenje porabe energije.
Merilni pogoji iz tega dokumenta se navezujejo na običajno uporabo opreme in se lahko razlikujejo od posebnih pogojev, kot so npr. določeni v varnostnih standardih.
