Overview

This European Standard provides methods to determine, by means of tests, measurements and/or calculations: - The energy consumption of desktop computers, integrated desktop computers and notebook computers in OFF mode, with Wake-on-LAN (when available) enabled and disabled; - The energy consumption of desktop computers, integrated desktop computers and notebook computers in other modes of operation, including low power state(s); - The lowest power state of desktop computers, integrated desktop computers and notebook computers; - The Discrete Graphics Card (dGfx) category, when applicable; - The internal power supply efficiency of desktop computers, integrated desktop computers, computer thin clients, workstations, small-scale servers and computer servers; - The availability and the behaviour of a power management function. This European Standard also suggests methods to determine, when such information is not otherwise available from a trustable source: - The efficiency of the external power supply supplied with the computer, if applicable; - The noise level of desktop computers, integrated desktop computers, computer thin clients, workstations, small-scale servers and computer servers; - The minimum number of loading cycles that the batteries can withstand; - The total mercury content in the integrated display, when applicable. This European Standard additionally provides guidance on information to be provided by manufacturers under some Ecodesign programmes or regulations, including, when applicable: - The results of the above mentioned energy efficiency measurements; - Energy efficiency parameters calculated from the above measurements (for example, the total energy consumption, based on a pre-defined duty cycle); - The external power supply efficiency; - The noise levels (the declared A-weighted sound power level) of the computer; - The minimum number of loading cycles that the batteries can withstand; - Whether internal batteries can be "accessed and replaced by a nonprofessional user", and whether the related text is present and legible on the external packaging; - User information on power management functionality; - The total mercury content in the integrated display. This European Standard applies to desktop computers, integrated desktop computers, notebook computers (including tablet computers, slate computers and mobile thin clients), desktop thin clients, workstations, mobile workstations, small-scale servers and computer servers, that can be powered directly from the mains alternating current (a.c.), including via an external or internal power supply. This European Standard may be applied to any type of computer and computer server not specifically excluded, regardless of its power demand. The responsible committee is DKE/K 742 "Audio-, Video- und Multimediasysteme, -geräte und -komponenten" ("Audio, video and multimedia systems, equipment and components") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
