Measure and record the average power consumption value over the test duration as P₁₀₀. Repeat the measurements with 35 lx (±2 lx), 12 lx (±1 lx), and 3 lux (±1 lx) entering the ABC sensor and record the values as P₃₅, P₁₂, and P₃ respectively. Testing shall be performed from the brightest to dimmest illuminance value and the values shall be changed by varying the input voltage to the light source.

Note:

The 3 lx illuminance value shall be simulated using a 67 mm 2 F-stop neutral density filter. 12 lx is measured at the ABC sensor prior to the application of the neutral density filter.

7.1.3.2. On Mode Power Calculation. All illuminance values shall be weighted equally when calculating the on mode power for a TV with ABC enabled by default and shall be determined by the following equation:

P_on = P₁₀₀ * W₁₀₀ + P₃₅ * W₃₅ + P₁₂ * W₁₂ + P₃ * W₃

Where:

W₁₀₀ = W₃₅ = W₁₂ = W₃ = 0.25

7.1.3.3. Lamp Requirements. A standard spectrum, halogen incandescent aluminized reflector lamp with a lamp diameter of 95 mm (±10 mm), a beam angle of 30 degrees (±10 degrees), and a center beam candlepower of 1500 cd (±500 cd) shall be positioned in front of the ABC sensor so that the light is directed into the sensor.

Note:

Lamps with spectrum modifying qualities, such as an IR coating, are not considered to meet a standard spectrum.

7.1.3.4. Light Source Set-up. The center of the lamp shall measure 1.5 m (±0.1 m) from the center of the ABC sensor. The light source shall be aligned ensuring that the center focal point of the lamp is perpendicular to the center of the ABC sensor.

7.2.1.2. ABC Configuration. The ABC sensor shall be disabled at all times during the luminance test. If the ABC sensor is incapable of being disabled through the TV settings menu, direct at least 300 lx of light into the ABC sensor.

7.2.1.3. Stabilization. Prior to the first luminance measurement, the TV must undergo a 10-minute re-stabilization period using the IEC 62087 Ed. 3.0 Blu-ray Disc^TM dynamic broadcast-content video signal.

7.2.2. Luminance Meter Set-up. Align the luminance meter perpendicular to the center of the TV screen. If a non-contact luminance meter is used to measure the screen luminance, the luminance measurement shall be taken at a distance capable of meeting the meter specifications outlined in section 3.1.3, and in accordance with the meter's user manual.

7.2.3. Three Vertical Bar Signal Measurement. The IEC 62087 Ed. 3.0 three vertical bar signal found in section 11.5.5 of IEC 62087 Ed. 3.0 (incorporated by reference, see § 430.3) shall be displayed for no more than 5 seconds when each luminance measurement is taken. The luminance measurement taken in the default picture setting within the home configuration shall be recorded as L_{Default__Home}.

7.2.4. Luminance in the Brightest Selectable Preset Picture Setting. Using the IEC 62087 Ed. 3.0 three vertical bar signal, determine the brightest selectable preset picture setting within the home configuration. Measure and record the screen luminance in the brightest selectable preset picture setting as L_{Brightest__Home}.

7.2.5. Retail Configuration Luminance Measurement. If the TV has a retail configuration and the retail configuration is acceptable for making a luminance measurement, measure and record the screen luminance in the default picture setting within the retail configuration as L_{Default__Retail}. A retail configuration is considered acceptable for a luminance measurement if the TV does not display a demo or ticker which alters the screen content, or if such features are present, they must be capable of being disabled for the entire re-stabilization period and measurement.

7.3. Standby Mode Test.

7.3.1. Video Input Device. The video input device shall be disconnected from the TV for all testing in standby mode.

7.3.2. Standby-Passive Mode. The standby-passive mode test shall be performed according to section 5.3.1 of IEC 62301 Ed. 2.0 (incorporated by reference, see § 430.3). Measure and record the average power consumption value over the test duration as P_{standby-passive}.

8. Annual Energy Consumption

8.1. Input Value. The annual energy consumption (AEC) of the TV shall be calculated using on mode, standby mode, and off mode power consumption values as measured pursuant to section 7.1, 7.3, and 7.4 respectively.

8.2. Rounding. Calculate the AEC of the TV using the equation below. The calculated AEC value shall be rounded as follows:

If the calculated AEC value is 100 kWh or less, the rated value shall be rounded to the nearest tenth of a kWh;

If the calculated AEC value is greater than 100 kWh, the rated value shall be rounded to the nearest kWh.

8.3. Calculations. Express the AEC in kWh per year, according to the following:

AEC = 365 * (P_on * H_on + P_{standby-active, low} * H_{standby-active, low} + P_{standby-passive} * H_{standby-passive} + P_off * H_off)/1000

Where:

P_m = power measured in a given mode m (in Watts)

H_m = hours per day spent in mode m

365 = conversion factor from daily to yearly

1000 = conversion factor from watts to kilowatts

Values for H_m (in hours/day) are specified in Table 2 of this section:
