# 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 4: Test set-up

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

(A) Test Set-up and Instrumentation: Test set-up and instrumentation for all portions of this method shall be in accordance with the requirements of International Electrotechnical Commission (IEC) 62301:2011, ‘Household electrical appliances — Measurement of standby power,’ Section 4, ‘General Conditions for Measurements,’ unless otherwise noted in this document. In the event of conflicting requirements, the Energy Star Test Method shall take precedence.
(B) AC Input Power: Products capable of being powered from AC mains shall be connected to a voltage source appropriate for the intended market, as specified in Table 10. If an external power supply is shipped with the product, it shall be used to connect the product to the specified voltage source.

(C) DC Input Power:
(1) Products may be tested with a DC source (e.g. via network or data connection) only if DC is the only available source of power for the product (i.e. no AC plug or External Power Supply (EPS) is shipped with the product).
(2) DC-powered products shall be installed and powered as directed by the manufacturer, using a port with the full specifications recommended for the Display (e.g. Universal Serial Bus (USB) 3.1 if applicable, even if backwards-compatible with USB 2.0).
(3) The power measurement shall be made between the DC source (e.g. Host Machine) and the cable shipped with the product, including the losses introduced by the shipped cable. If no cable is shipped with the product, any cable between 2 and 6 feet long may be used in its place. The resistance of the cable used to connect the Display to the point of measurement shall be measured and reported.
Note: The measured resistance of DC power cables includes the sum of resistances of both the DC supply voltage wire and the ground wire.
(4) A spliced cable may be used between the shipped cable and DC source in order to connect the power meter. If this method is used, the following requirements must be met:
(a) The spliced cable shall be used in addition to the shipped cable described in Section 4(C)(3).
(b) The spliced cable shall be connected between the DC source and the shipped cable.
(c) The spliced cable shall be no longer than 1 foot.
(d) For measuring voltage, the total amount of wiring used between the voltage measurement and the shipped cable shall be less than 50 milliohms of resistance. This only applies to the wiring that is carrying load current.
Note: Voltage and current need not necessarily be measured at the same location, so long as the voltage is measured within 50 milliohms of the shipped cable.
(e) The current measurement can be made either on the ground wire or the DC supply voltage wire.
(f) Figure 1 depicts an example spliced cable set-up using a USB 2.0-powered Display connected to the Host Machine.

(D) Ambient Temperature: Ambient temperature shall be 23 °C ± 5 °C.
(E) Relative Humidity: Relative humidity shall be from 10 % to 80 %.
(F) UUT Alignment:
(1) All four corners of the face of the Unit Under Test (UUT) shall be equidistant from a vertical reference plane (e.g. wall).
(2) The bottom two corners of the face of the UUT shall be equidistant from a horizontal reference plane (e.g. floor).
(G) Light Source for On Mode Testing:
(1) Lamp Type:
(a) Standard spectrum halogen flood reflector lamp. The lamp shall not meet the definition of ‘Modified spectrum’ as defined in 10 CFR 430.2 — Definitions.
(b) Rated Brightness: 980 ± 5 % lumens.
(2) Light Source Alignment for Testing Products With ABC Enabled By Default:
(a) There shall be no obstructions between the lamp and the UUT's Automatic Brightness Control (ABC) sensor (e.g. diffusing media, frosted lamp covers, etc.).
(b) The centre of the lamp shall be placed at a distance of 5 feet from the centre of the ABC sensor.
(c) The centre of the lamp shall be aligned at a horizontal angle of 0° with respect to the centre of the UUT's ABC sensor.
(d) The centre of the lamp shall be aligned at a height equal to the centre of the UUT's ABC sensor with respect to the floor (i.e. the light source shall be placed at a vertical angle of 0° with respect to the centre of the UUT's ABC sensor).
(e) No test room surface (i.e. floor, ceiling, and wall) shall be within 2 feet of the centre of the UUT's ABC Sensor.
(f) Illuminance values shall be obtained by varying the input voltage of the lamp.
(g) Figure 2 and Figure 3 and provide more information on UUT and light source alignment.

Notes:
D1 = D2 with respect to vertical reference plane,

H3 and H4 indicate that the centre of the light sensor must be at least 2 feet from the floor and 2 feet from the ceiling,
illuminance meter removed for power measurements, after target illuminance achieved.
(H) Power Meter: Power meters shall possess the following attributes
(1) Crest Factor:
(a) An available current crest factor of 3 or more at its rated range value; and
(b) Lower bound on the current range of 10 mA or less.
(2) Minimum Frequency Response: 3,0 kHz
(3) Minimum Resolution:
(a) 0,01 W for measurement values less than or equal to 10 W;
(b) 0,1 W for measurement values from greater than 10 W to 100 W; and
(c) 1,0 W for measurement values greater than 100 W.
(I) Luminance and Illuminance Meters:
(1) Luminance measurement shall be performed using either
(a) A contact meter; or
(b) A non-contact meter.
(2) All luminance and illuminance meters shall be accurate to ± 2 % (± 2 digits) of the digitally displayed value.
(3) Non-contact luminance meters shall have an acceptance angle of 3 degrees or less.
The overall accuracy of a meter is found by taking (±) the absolute sum of 2 % of the measurement and a 2-digit tolerance of the displayed value least significant digit. For example, if an illuminance meter displays ‘200,0’ when measuring a screen brightness of 200 nits, 2 % of 200 nits is 4,0 nits. The least significant digit is 0,1 nits. ‘Two digits’ implies 0,2 nits. Thus, the displayed value would be 200 ± 4,2 nits (4 nits + 0,2 nits). The accuracy is specific to the illuminance meter and shall not be considered as tolerance during actual light measurements.
(J) Measurement Accuracy:
(1) Power measurements with a value greater than or equal to 0,5 W shall be made with an uncertainty of less than or equal to 2 % at the 95 % confidence level.
(2) Power measurements with a value 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.
(3) All ambient light values (measured lux) shall be measured at the location of the ABC sensor on the UUT with light entering directly into the sensor and with the main menu from the test signal from IEC 62087:2011, ‘Methods of measurement for the power consumption of audio, video and related equipment’ displayed on the product. For products not compatible with the IEC test signal format, ambient light values shall be measured with the Video Electronics Standard Association (VESA) Flat Panel Display Measurements Standard version 2.0 (FPDM2) FK test signal being displayed on the product.
(4) Ambient light values shall be measured within the following tolerances:
(a) At 12 lux, ambient lighting shall be within ± 1,0 lux; and
(b) At 300 lux, ambient lighting shall be within ± 9,0 lux.
