Title Desktop and notebook computers - Measurement of energy consumption
Project Number 23388
Abstract/Scope IEC 62623:2012 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 and 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. Keywords: Power consumption, Desktop computer, Notebook computer

Superseded by  
Normative reference (6) ECMA-389

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
