the configuration of special functions, the most power consumptive
configuration shall be selected. If it is unknown which
configuration yields the most power consumptive state, verify the
selection by measuring the power consumption of each possible
configuration.
Note:
The selection of the home or retail configuration within the
forced menu is not considered the configuration of a special
function, and is therefore exempt from this requirement.
5.6. On Mode Picture Setting. Ensure that the TV is in
the default picture setting within the home configuration for all
on mode tests. This picture setting shall only be changed as
instructed by the luminance test.

6. Calculation of Average Power Consumption
6.1. Average Power Calculation. For all tests in the on,
standby-active, low, and standby-passive modes, the average power
shall be calculated using one of the following two methods:
6.1.1. Record the accumulated energy (Ei) in kilo-watt hours
(kWh) consumed over the time period specified for each test (Ti).
The average power consumption is calculated as Pi = Ei/Ti.
6.1.2. Record the average power consumption (Pi) by sampling the
power at a rate of at least 1 sample per second and computing the
arithmetic mean of all samples over the time period specified for
each test (Ti).
The resulting average power consumption value for each mode of
operation shall be rounded according to the accurary requirements
specified in section 3.3.3 of this section.
7. Test Measurements.
7.1. On Mode Test.
7.1.1. On Mode Stabilization. If the TV has an ABC sensor
enabled by default, direct at least 300 lx into the ABC sensor. The
TV shall be stabilized prior to testing on mode using the IEC 62087
Ed. 3.0 Blu-ray Disc TM dynamic broadcast-content video signal in
accordance with section 11.4.2 of IEC 62087 Ed. 3.0 (incorporated
by reference, see § 430.3).
7.1.2. On Mode Test for TVs without ABC Enabled by
Default. The following test shall be performed if the TV is
shipped with ABC disabled by default or the ABC function is
unavailable. Display the IEC 62087 Ed. 3.0 Blu-ray Disc TM dynamic
broadcast-content video signal for one 10-minute period
(incorporated by reference, see § 430.3). Measure and record the
average power consumption value over the test duration as Pon.
7.1.3. On Mode Test for TVs with ABC Enabled by Default.

3.0 Blu-ray Disc TM dynamic broadcast-content video signal for one
10-minute period (incorporated by reference, see § 430.3) with 100
lx (±5 lx) entering the ABC sensor. 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:
Pon = 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

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 LDefault_Home.
7.2.4. Luminance in the Brightest Selectable Preset Picture
Setting. Using the IEC 62087 Ed. 3.0 three vertical bar signal,

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 * (Pon * Hon + Pstandby-active, low * Hstandby-active,
