FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.

5.6.4 Light source for specific illuminance levels
The light source used for illuminating the ABC sensor to specific illuminance levels shall use a
dimmable halogen lamp in a sealed LED reflector lamp and shall have a diameter of 120 mm
or less 90 mm ± 5mm. The rated beam angle of the lamp shall be 40° ± 5°. The rated correlated
colour temperature (CCT) of the light source shall be 2 800 2 700 K ± 300 K at its rated voltage.
The rated CRI shall be 80 ± 3. The front surface of the lamp shall be clear (i.e., not coloured or
coated with a spectrum modifying material) and may have a smooth or granular front surface;
when shined against a uniform white surface, the diffusion pattern should appear smooth to the
naked eye. The lamp assembly shall not modify the spectrum of the halogen LED source,
including the IR and UV bands.
The lamp shall be capable of providing the highest illumination level chosen in 6.2.8 within the
range of 70 % to 110 % of its rated voltage when configured as specified in 6.3.8.
For luminance levels below 10 lx, a 2 stop ND filter (3.1.10) shall be used. No ND filter shall be
used for luminance levels at or above 10 lx. The ND filter shall be of the absorptive type and
shall be large enough to cover the entire light acceptance area of the ABC sensor assembly
with a margin of at least 5 mm on all sides. The ND filter shall have an average transmission of
25 % ± 2,5 % within the visible range, which is 400 nm to 700 nm, without selectively absorbing
light at specific wavelengths.
To reach the illumination levels specified in 6.2.8, the lamp shall be wired with a compatible
dimming switch capable of dimming it to the lowest level required in 6.2.8. The lamp shall be
capable of providing the highest illumination level when wired with the dimming switch. For
luminance levels below 10 lx, a 2-stop ND filter (3.1.19) may be used if the lowest setting of the
lamp and dimmer combination does not reach the required level below 10 lx. No ND filter shall
be used for luminance levels at or above 10 lx. The ND filter shall be large enough to cover the
entire surface of the diffusion area of the lamp. The ND filter shall have an average transmission
of 25 % ± 2,5 % within the visible range, which is 400 nm to 700 nm, without selectively
absorbing light at specific wavelengths.
Caution: the lamp shall be compatible with leading-edge or forward-phase dimmers (i.e. the
lamp luminance does not vary with voltage).
Specific illuminance levels shall be obtained by controlling the voltage and/or duty cycle to the
above light source adjusting the dimming switch.
The model of the lamp and dimmer (and versions thereof if available) used for illuminating the
ABC sensor to specific illuminance levels shall be reported.
Some lighting controllers, such as those with SCR-based circuits, may introduce current spikes
into the power source. Such controllers should be avoided or otherwise isolated from the power
source for the UUT.
The lamp should be stabilized before testing by setting it to deliver the maximum tested lux to
the ABC sensor in accordance with 6.4.2 and maintaining that light level for 10 minutes.
Stabilisation may be carried out during the setting up of the light source (see 6.3.7).
5.6.5 Light source for disabling the ABC feature
The light source used for disabling the ABC feature shall use a dimmable halogen lamp in a
sealed reflector and shall have a diameter of 120 mm or less. The rated correlated colour
temperature shall be 2 800 K ± 300 K at its rated voltage. The front surface of the lamp shall
be clear (i.e., not coloured or coated with a spectrum modifying material) and may have a
smooth or granular front surface. The lamp assembly shall not modify the spectrum of the
halogen source, including the IR and UV bands. The light source shall be capable of providing
300 lx or greater when applied directly to the ABC sensor assembly.
The model of the lamp used for disabling the ABC feature shall be reported.
The same light source as that used in 5.6.4 may be used to override the ABC feature by reducing
the distance between the light source and the TV’s ABC sensor.
The manufacturer, model and version of the LED bulb used to override the ABC feature shall
be reported.
5.6.6 Networking equipment
For wireless connectivity, a Wi-Fi wireless access point that is compatible with
IEEE 802.11-2007 shall be used.

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

5.6.4 Light source for specific illuminance levels
The light source used for illuminating the ABC sensor to specific illuminance levels shall use a
dimmable LED reflector lamp and shall have a diameter of 90 mm ± 5mm. The rated beam angle
of the lamp shall be 40° ± 5°. The rated correlated colour temperature (CCT) of the light source
shall be 2 700 K ± 300 K at its rated voltage. The rated CRI shall be 80 ± 3. The front surface
of the lamp shall be clear (i.e., not coloured or coated with a spectrum modifying material) and
may have a smooth or granular front surface; when shined against a uniform white surface, the
diffusion pattern should appear smooth to the naked eye. The lamp assembly shall not modify
the spectrum of the LED source, including the IR and UV bands.
To reach the illumination levels specified in 6.2.8, the lamp shall be wired with a compatible
dimming switch capable of dimming it to the lowest level required in 6.2.8. The lamp shall be
capable of providing the highest illumination level when wired with the dimming switch. For
luminance levels below 10 lx, a 2-stop ND filter (3.1.19) may be used if the lowest setting of the
lamp and dimmer combination does not reach the required level below 10 lx. No ND filter shall
be used for luminance levels at or above 10 lx. The ND filter shall be large enough to cover the
entire surface of the diffusion area of the lamp. The ND filter shall have an average transmission
of 25 % ± 2,5 % within the visible range, which is 400 nm to 700 nm, without selectively
absorbing light at specific wavelengths.
Caution: the lamp shall be compatible with leading-edge or forward-phase dimmers (i.e. the
lamp luminance does not vary with voltage).
Specific illuminance levels shall be obtained by adjusting the dimming switch.
The model of the lamp and dimmer (and versions thereof if available) used for illuminating the
ABC sensor to specific illuminance levels shall be reported.
The lamp should be stabilized before testing by setting it to deliver the maximum tested lux to
the ABC sensor in accordance with 6.4.2 and maintaining that light level for 10 minutes.
Stabilisation may be carried out during the setting up of the light source (see 6.3.7).
5.6.5 Light source for disabling the ABC feature
The same light source as that used in 5.6.4 may be used to override the ABC feature by reducing
the distance between the light source and the TV’s ABC sensor.
The manufacturer, model and version of the LED bulb used to override the ABC feature shall
be reported.
5.6.6 Test table surface material
The table used to hold the UUT shall be covered with black, minimally reflective cloth and shall
have the area immediately in front of and underneath the UUT’s ABC sensor, as shown in
Figure 4, covered with material having a gloss measurement of 15 GU as measured by a 60°
gloss meter. The material shall not alter visible light in the 400 nm to 700 nm range that arrives
on, or is reflected by, the material. The thickness of the ABC sensor table surface material shall
be 4 mm or less and shall be at least 203 mm wide by 177 mm deep; it shall be printed with a
matte finish, with a colour adhering to the M1 lighting standard having CMYK values of (43, 53,
84, 84) ± 2. The card shall not polarize light reflected off its surface.
NOTE See Annex D for further information.
6 Procedures
6.1 Order of activities
The following order of activities is recommended (also represented in Figure 2):
– preparation (6.2),
– initial activities (6.3),
– determination of power consumption, On mode (6.4),
– determination of peak luminance ratio and power factor (6.4.5.5),
– determination of power consumption, Partial On mode (6.6),
– determination of power consumption, Off mode (6.7).
The above order is chosen to ensure proper stabilization prior to the taking of each
measurement. The technician performing the activities may vary the order as needed. However,
the stabilization process prior to the taking of each measurement shall effectively be the same
as if the recommended order had been followed.
A flowchart with the comprehensive measurement process is provided in Annex E, Figure E.1.
Countdown timers and 50 % grey field endings have been added to most of the video signal
test clips referenced by this document to allow test personnel to easily maintain a UUT’s
stabilization while moving from one measurement method to the next. It is easy to inspect a
given test’s power consumption log to note when the test both started and ended. Test
personnel are encouraged to familiarize themselves with each video signal test clip prior to
using them for actual testing.
