ECMA-383 1st Edition / June 2008 Measuring Energy Consumption, Performance and Capabilities of ICT and CE Products Ecma International Rue du Rhne 114 CH-1204 Geneva T/F: +41 22 849 6000/01 www.ecma-international.org PC Measuring Energy Consumption, Performance and Capabilities of ICT and CE Products Standard ECMA-383 1st Edition / June 2008 . Introduction Ecma developed and published the worlds first environmentally conscious design standard (ECD) for the ICT and Lower bound on the current range of 10 mA or less. Have a frequency response of at least 3 kHz; and Be calibrated with a standard that is traceable internationally. Be able to average power accurately over any user selected time interval (this is usually done with an internal maths calculation dividing accumulated energy by time within the meter, which is the most accurate approach). Or, alternatively, the meter shall be capable of integrating energy over any user selected time interval with an energy resolution of less than or equal to 0.1 mWh and integrating time displayed with a resolution of 1 second or less. Provide a control and logging interface that the Benchmark uses to allow logging of the data onto a control system. Accuracy of power measurement Measurements of power of 0.5 W or greater shall be made with an uncertainty of less than or equal to 2 % at the 95 % confidence level. Measurements of power of less than 0.5 W shall be made with an uncertainty of less than or equal to 0.01 W at the 95 % confidence level. The power measurement instrument shall have a resolution of: 0.01 W or better for power measurements of 10 W or less; 0.1 W or better for power measurements of greater than 10 W up to 100 W; and 1 W or better for power measurements of greater than 100 W. All power measurements shall be in watts and rounded to the second decimal place. For power measurements greater than or equal to 10 W, three significant figures shall be reported. - 7 - - 8 - Annex C (normative) Results reporting format Results from this test methodology shall be presented in the following order: 1.
