# Commission Decision (EU) 2016/1756 of 28 September 2016 determining the European Union position with regard to a decision of the management entities under 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, on the revision of specifications for displays included in Annex C to the Agreement (Text with EEA relevance), Division 6.2: Luminance testing

Extent: E+W+S+N.I.

(A) Luminance testing shall be performed immediately following the warm up period and in dark room conditions. Product screen illuminance, as measured with the UUT in Off Mode, shall be less than or equal to 1,0 lux.
(B) Luminance shall be measured perpendicular to the centre of the product screen using a luminance meter in accordance with the meter's user manual.
(C) The position of the luminance meter relative to the product screen shall remain fixed throughout the duration of testing.
(D) For products with ABC, luminance measurements shall be performed with ABC disabled. If ABC cannot be disabled, luminance measurements shall be measured perpendicular to the centre of the product screen with light entering directly into the UUT's ambient light sensor at greater than or equal to 300 lux.
(E) Luminance measurements shall be performed as follows:
(1) Verify that the UUT is in the default as-shipped luminance value or ‘Home’ picture setting.
(2) Display the test video signal for the specific product class, as described below:
(a) All products, except as specified in (b): Three-bar video signal specified in IEC 62087:2011, Section 11.5.5 (three bars of white (100 %) over a black (0 %) background).
(b) Products that cannot display signals from IEC 62087:2011: VESA FPDM2 L80 test signal for the maximum resolution supported by the product.
(3) Display the test video signal for no less than 10 minutes to allow the UUT luminance to stabilise. This 10-minute stabilisation period may be reduced if luminance measurements are stable to within 2 % over a period of not less than 60 seconds.
(4) Measure and record the luminance in default as-shipped setting LAs-shipped.
(5) Set the brightness and contrast levels of the UUT to their maximum values.
(6) Measure and record the luminance as LMax_Measured.
(7) Record the manufacturer-reported maximum luminance LMax_Reported.
(F) The contrast setting shall be left at the maximum level for the subsequent On Mode tests unless otherwise specified.
