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 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.
