# Council Decision of 13 November 2012 on the signing and conclusion of the Agreement between the Government of the United States of America and the European Union on the coordination of energy-efficiency labelling programmes for office equipment (Text with EEA relevance) (2013/107/EU), Division 3: Measuring luminance


After the IEC test clip has run and the power consumption has been recorded, the technician shall measure the product's luminance using the methodology described below. Note, the technician shall not alter the product's settings from how they were set during the power consumption test.
(1) Using the three bar video signal (Lt) static test image referenced in section 11.5 of IEC 62087, measure the center point, axial luminance of the display per the Video Electronics Standards Association (VESA) Flat Panel Display Measurements Standard (FPDM) Version 2.0, section 301-2H.
(2) Report in OPS the measured luminance value in candelas per square meter (cd/m2), rounded to the nearest whole number.
(3) All luminance measurements should be performed in accordance with the test conditions outlined above for large displays. Specifically, measuring the luminance must be conducted with the display's settings as they are shipped from the factory. For products with a forced menu, measurements shall be conducted in standard, or home mode.
