# Commission Regulation (EU) 2019/2021 of 1 October 2019 laying down ecodesign requirements for electronic displays pursuant to Directive 2009/125/EC of the European Parliament and of the Council, amending Commission Regulation (EC) No 1275/2008 and repealing Commission Regulation (EC) No 642/2009 (Text with EEA relevance), Division 3: Verification tolerances

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

The Member State authorities shall only apply the verification tolerances that are set out in Table 3. No other tolerances, such as those set out in harmonised standards or in any other measurement method, shall be applied.
The verification tolerances defined in this Annex relate only to the verification of the measured parameters by the Member State authorities and shall not be used by the manufacturer as an allowed tolerance on the values in the technical documentation to achieve compliance with the requirements. Declared values shall not be more favourable for the manufacturer than the values reported in the technical documentation.
Table 3
Verification tolerances
In the case of three additional units tested as prescribed in Annex IV point 2(a), the determined value means the arithmetic mean of the values determined for these three additional units.
Parameter
Verification tolerances
On mode power demand, (Pmeasured , Watts) excluding allowances and adjustments in Annex II, point B, for the purposes of EEI calculation set out in Annex II, point A.
The determined value shall not exceed the declared value by more than 7 %
Off mode, standby mode and networked standby mode power demand (Watts), as applicable
The determined value shall not exceed the declared value by more than 0,1 Watt if the declared value is 1,0 W or less, or by more than 10 % if the declared value is more than 1,0 W
Peak white luminance ratio
Where applicable, the determined value shall not be lower than 60 % of the peak white luminance of the brightest on mode configuration provided by the electronic display
Peak white luminance (cd/m2)
The determined value shall not be lower than the declared value by more than 8 %
Visible screen diagonal in centimetres (and inches, if declared)
The determined value shall not be lower than the declared value by more than 1 cm (or 0,4 inches).
Screen area in dm2
The determined value shall not be lower than the declared value by more than 0,1 dm2
Timed functions as set out in Annex II, points C.3 and C.4
The switch shall be completed within 5 seconds of the set out values
Weight of plastic components as qualified in Annex II, point D.2
The determined value shall not be different from the declared value by more than 5 grams
