RIN: 1904-AC29

Energy Conservation Program: Test Procedure for Television Sets

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy.

ACTION: Notice of proposed rulemaking.

SUMMARY: The U.S. Department of Energy (DOE) proposes to establish a new test procedure 

for television sets (TVs). DOE repealed the prior Federal test procedure for TVs on October 20, 

2009, due to petitions from the California Energy Commission (CEC) and the Consumer 

Electronics Association (CEA). CEC and CEA petitioned for the repeal in light of the June 13, 

2009, Federal Communications Commission (FCC) transition from analog to digital broadcast 

transmissions for TVs. In their petitions, the CEC requested repeal of the regulatory provisions 

establishing the test procedure and defining “television set,” and the CEA petitioned for DOE’s 

adoption of the International Electrochemical Commission’s (IEC’s) test procedure IEC Standard 

62087-2008, “Methods of measurement for the power consumption of audio, video and related 

equipment.” DOE is proposing a new test procedure for TVs that was developed from existing 

industry test procedures including those by IEC, Environmental Protection Agency (EPA), and 

CEA. Additionally, DOE will hold a public meeting to receive and discuss comments on the 

proposal.

I. Authority and Background

A. General

Title III of the Energy Policy and Conservation Act (42 U.S.C. 6291, et seq.; “EPCA” or, 

“the Act”) sets forth a variety of provisions designed to improve energy efficiency. (All 

references to EPCA refer to the statute as amended through the Energy Independence and 

Security Act of 2007 (EISA 2007), Pub. L. 110-140 (Dec. 19, 2007)). Part B of Title III (42 

U.S.C. 6291–6309), which was subsequently redesignated as Part A for editorial reasons, 

establishes the “Energy Conservation Program for Consumer Products Other Than 

Automobiles.” This includes television sets (TVs), the subject of this notice. (42 U.S.C. 

6292(a)(12)) 

Under EPCA, this program consists essentially of three parts: (1) testing, (2) labeling, and 

(3) Federal energy conservation standards. The testing requirements consist of test procedures 

that manufacturers of covered products must use (1) as the basis for certifying to DOE that their 

products comply with the applicable energy conservation standards adopted under EPCA, and 

(2) for making representations about the efficiency of those products. Similarly, DOE must use 

these test requirements to determine whether the products comply with any relevant standards 

promulgated under EPCA. 
7

B. Test Procedure Rulemaking Process

In 42 U.S.C. 6293, EPCA sets forth the criteria and procedures DOE must follow when 

prescribing or amending test procedures for covered products. Specifically, if DOE determines 

that a test procedure should be prescribed or amended, it must publish the proposed test 

procedure in the Federal Register and give interested parties an opportunity to provide public 

comment on the procedures. (42 U.S.C. 6293(b)(2)) EPCA also provides that the test procedure 

shall be reasonably designed to produce test results which measure energy efficiency, energy 

use, or estimated annual operating cost of a covered product during a representative average use 

cycle or period of use, and shall not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))

EISA 2007 amended EPCA to require DOE to implement a standby and off mode energy 

consumption measurement, if technically feasible, in test procedures where not previously 

present. Otherwise, DOE must prescribe a separate standby and off mode energy test procedure, 

if technically feasible. (42 U.S.C. 6295(gg)(2)(A)) EISA 2007 also requires any final rule to 

establish or revise a standard for a covered product, adopted after July 1, 2010, to incorporate 

standby mode and off mode energy use into a single amended or new standard, if feasible. (42 

U.S.C. 6295(gg)(3)(A)) DOE recognizes that the standby and off mode conditions of operation 

apply to the product covered by this rulemaking. In response to this requirement, DOE proposes 

adopting provisions in the test procedures to address standby and off mode as discussed in 

section III.E.5 of this proposed rulemaking.
8

C. Rulemaking Background

DOE adopted a test procedure for TVs on June 29, 1979, codified at 10 CFR part 430, 

subpart B, appendix H. 44 FR 37938. In May 2008, DOE received petitions from both the 

California Energy Commission (CEC) and the Consumer Electronics Association (CEA), which 

were drafted in light of the June 13, 2009, Federal Communications Commission (FCC)

transition from analog to digital broadcast transmissions for TVs1. As of June 12, 2009, the 

Digital Transition and Public Safety Act of 2005 required that all broadcasting stations transmit 

in digital to make analog frequencies available for public safety communications4. Both the CEC 

and the CEA petitioned for repeal of the regulatory provisions establishing the test procedure. 

CEC’s petition stated that the old test procedure was not capable of accurately measuring the 

energy consumption of modern TVs because TV broadcasting is no longer transmitted via an 

analog signal2. In addition, the CEA petitioned for DOE’s adoption of the International 

Electrochemical Commission’s (IEC) test procedure IEC 62087-2008, “Methods of measurement 

for the power consumption of audio, video and related equipment.” 74 FR 53641. In light of 

these petitions, and the fact that the previous test procedure was largely obsolete for today’s 

products because of the mandated transition from analog to digital signal transmission, DOE

repealed the test procedure on October 20, 2009. The test procedure DOE is proposing today 

seeks to rectify the problem with the old test procedure by allowing for accurate measurement of 

the energy consumption of modern TVs.

DOE notes that the National Technology Transfer and Advancement Act of 1995 (Pub. 

L. 104–113) directs Federal agencies to use voluntary consensus standards in lieu of Government 

standards whenever possible. Consequently, as described in today’s NOPR, DOE incorporates by 

reference in its test procedures the generally accepted test procedures or recognized industry 

standards, such as those issued by the IEC, the Environmental Protection Agency (EPA), or the 

CEA, that provide either specific aspect(s) of the test procedure, or complete test procedures, for 

the specified modes.

As the first step in this rulemaking to establish a new test procedure, DOE published a 

Request for Information on September 3, 2010, 75 FR 54048, (the 2010 RFI) requesting 

stakeholders to provide information and views on DOE utilizing both the IEC 62087-2008 and 

the ENERGY STAR®Program Requirements for Televisions, Version 4.1 (ENERGY STAR v. 

4.1) as reference standards for the basis of a new DOE test procedure3. DOE also solicited 

comments on the key issues affecting the development of a new test procedure including the 

following:

1) An appropriate method for ensuring screen brightness,

2) Utilizing the nine point video signal,

3) An appropriate method for measuring screen luminance,

4) Requiring testing on all preset viewing modes,

 

5 When the RFI was published, the most current version of EPA’s test procedure was ENERGY STAR v. 4.1 and the 

most recent version of the IEC-62087 was 2008. Since then, EPA has published an updated version, “ENERGY 

STAR Program Requirements for Televisions, Version 5.3” and the IEC has published an updated version, “IEC 

62087-2011”
10

5) Testing multiple illuminance levels (specifically 10, 100, 150 and 200 lux),

6) An appropriate method for generating illuminance,

7) The best possible signal source and connection to that signal source,

8) An appropriate stabilization time for luminance and power measurements,

9) An appropriate method of testing 3D energy consumption,

10) Measuring download acquisition mode (DAM) power, 

11) Measuring internet connectivity power,

12) Measuring power saving technology energy (including presence sensors, display 

power management systems (DPMS), and high-definition multimedia interface 

consumer electronic controls (HDMI-CEC)), and

13) The scope of coverage for the rulemaking. 75 FR 54048.

II. Summary of the Notice of Proposed Rulemaking

In today’s NOPR, DOE is proposing a new test procedure for determining the energy use 

of TVs. The proposed test procedure includes measuring screen luminance and testing energy 

consumption for active (on mode), standby, and off modes. 

The luminance test is proposed to be performed by measuring the screen luminance while 

the TV is displaying the IEC 62087-2011 three bar video signal in both the home and retail 

picture settings. The luminance test is being proposed to allow the ENERGY STAR program to 

utilize the measurement. The on mode test will measure on mode energy consumption when the 

TV is displaying the IEC 62087-2011 dynamic broadcast-content video signal. If the TV is 
11

shipped with an automatic brightness control (ABC) sensor enabled by default, on mode will be 

tested at various room illuminance levels. If the TV does not have an ABC sensor or the sensor is 

disabled by default, the test would be performed while the TV is in the home picture setting.

DOE’s proposed standby test procedure incorporates both IEC 62087-2011 “Methods of 

measurement for the power consumption of audio, video and related equipment” and the CEA 

“Procedure for DAM Testing: For TVs” (CEA DAM test procedure). DOE’s proposed off mode 

test procedure incorporates IEC 62087-2011. 

Although DOE is aware of TVs with additional modes, DOE is not proposing to require 

testing these, but rather is simply considering these modes and requesting comment on them.

These modes include: 

1) On mode tests for TVs with internet connectivity;

2) 3D mode, if capable; and 

3) Standby-active, low mode (when the internet is enabled but the TV is in standby,

and the TV is not sending or receiving external data, for those TVs with internet 

access).
12

To supports its efforts in developing a Federal test procedure, DOE conducted various 

tests, the results of which can be found on the DOE website4. The information found on the DOE 

website helps support this NOPR by providing additional data and clarification. DOE conducted 

testing at two different testing facilities and therefore some of the data is organized according to 

where that data was collected. The data from test facility one is denoted with numerical values,

while the data from test facility two is denoted with alphabetical letters. The test facilities were 

determined to produce similar results as indicated in the Round Robin Test Program Final Report 

for Televisions. This information, found on the DOE website5, includes the following:

1) Television Test Procedure Comparison Chart which compares key aspects of 

various TV standards including IEC 62087-2011, CEA 2037-2010, ENERGY STAR 

version 5.1, CEC, BS EN 62087 “Methods of measurement for the power 

consumption of audio, video, and related equipment”, and EN 62087 “Methods of 

measurement for the power consumption of audio, video, and related equipment”.

2) Video Signal of Test Patterns Comparison Table which compares the different 

advantages and disadvantages of particular video signals including the 3-bar, 9-point, 

DOE 5- point, and dynamic video signals. DOE assessed these video signals based 

on their availability, impact on average picture level (APL), affect on power limiting, 

and interested party input among other features.

3) Room Illuminance Measurements During TV Viewing: Pilot Study which 

summarizes a pilot study that DOE conducted to continuously measure room 

illuminance in nine homes over a period of a week or more as well as taking discrete 

one-off measurements at different locations in the room. This document also sets out 

the detailed methodology that DOE used for its pilot study. 

4) Round Robin Test Program Final Report for Televisions that summarizes a round 

robin test study to assess the repeatability and reproducibility of TV energy test 

results. This round robin study utilized the ENERGY STAR version 5.1 test 

procedure across three labs and compares their results.

5) Television Energy and Luminance Test Data Set which includes the energy and 

luminance data for all of the TVs on which DOE conducted testing.

a) Television Luminance Data which includes test results for luminance testing 

using the 9-point (both perpendicular and off-axis measurements), 5-point Video 

Electronics Standards Association (VESA), and DOE 5-point video signals. DOE 

conducted luminance testing based on the ENERGY STAR version 5.1 test 

procedure but altered the video signal to determine which video signal was most 

appropriate. DOE used the 3-bar static video signal specified in IEC 62087 Ed. 

2.0 as well as the 9-point, VESA 5-point, and DOE 5-point video signals as 

specified in this NOPR.
14

b) Television Luminance Stabilization Period Data which includes graphs 

indicating how TV screen luminance changes over time and with respect to 

different stabilization periods. DOE took measurements of screen luminance after 

different stabilization periods to determine the most appropriate method for 

conducting luminance testing. DOE initially warmed-up the TVs using the 

method from IEC 62087-2011 and then displayed the video signal for 15 minutes 

to conduct the luminance measurement. The second luminance measurement was 

taken after a 10 minute warm-up period followed by 2 minutes of a black screen. 

DOE tested this stabilization period for both the IEC 3-bar and 9-point video 

signals.

c) Television Power Data that includes test results for power consumption testing 

while TVs are in various different modes. DOE conducted this testing according 

to the ENERGY STAR version 5.1 test method, but adjusted specific aspects on 

the TV to determine the energy consumption associated with that particular 

feature including volume, ABC, and internet connectivity. 

d) Television Internet Standby Data which is comprised of data indicating the 

energy consumption when TVs are in standby mode and connected to various 

external sources including HDMI, cable, Ethernet, and wireless internet. DOE 

conducted power consumption testing according to the ENERGY STAR v. 5.3

standby test procedure while alternating the specific internet connections present 

on the TV. 
15

e) Television 9-point Video Signal Comparison Data that includes data depicting 

the difference between perpendicular and off-axis measurements while the TV is 

displaying the 9-point video signal. Luminance results were collected according 

to the ENERGY STAR version 5.1 test procedure, except that DOE altered the 

video signal to the 9-point video signal specified in this NOPR.

f) Television On Mode Automatic Brightness Control Data which includes the 

power and luminance data for TVs tested by DOE with ABC enabled by default 

across various room illuminance levels. A PowerPoint which charts some of this 

data is also included to demonstrate the range of implementation of ABC among 

TVs tested by DOE. DOE conducted power consumption testing according to the 

ENERGY STAR v. 5.3 (with additional room lighting levels) using the IEC 

dynamic test clip specified in IEC 62087 Ed. 2.0. Luminance results were 

collected according to the ENERGY STAR version 5.1 test procedure, using the 

3-bar static test pattern specified in IEC 62087 Ed. 2.0.

g) Television Download Acquisition Mode Data which includes data indicating the 

energy consumption associated with DAM mode. DOE conducted this testing on 

two TVs by configuring the internal electronic program guide (not enabled by 

default) and connecting to a subscription cable service by (1) coaxial cable only, 

(2) Ethernet only and (3) cable and Ethernet together. Results over a 24 hour 

period were recorded and charted for each connection configuration.
16

h) Television 3D Mode Data that contains data as to TV energy consumption while 

in various 3D modes. This testing was conducted on five TVs under the following 

modes: when the TV is displaying a 3D video signal, when the TV is upconverting a 2D video signal to 3D, and when the TV is receiving a video signal 

from a Blu-ray player that has up-converted a 2D video signal to 3D.

DOE believes that the proposed test procedure will accurately represent the energy 

consumption of TVs by capturing the annual energy consumption in on mode, standby mode, 

and off mode. However, DOE requests comments from interested parties on improvements or 

changes to the proposed test procedure. DOE will consider modifications that improve the 

accuracy, precision of language, or other elements of the procedure and/or decrease the testing 

burden.In submitting comments, interested parties should state the nature of the recommended 

modification and explain how it would improve upon the test procedure proposed in this NOPR. 

Interested parties should also submit data, if any, to support their positions.

III. Discussion

A. Effective Date and Compliance Date of Test Procedure

If adopted, the effective date for this test procedure would be 30 days after publication of 

the test procedure final rule in the Federal Register. At that time, the new metrics and any other 

measure of energy consumption which depends on these metrics may be represented pursuant to 

the final rule. Compliance with the new test procedure for representation purposes would be 

required 180 days after the date of publication of the test procedure final rule. On or after that 

date, any such representations, including those made on marketing materials and product labels,
17

must be based upon results generated under the final test procedure proposed to be included in 

Appendix H to Subpart B of 10 CFR Part 430.

Furthermore, EPCA requires the Federal Trade Commission (FTC) to prescribe labeling 

rules for certain covered products including TVs. (42 U.S.C. 6294(a)(2)(I)) Hence, the final DOE 

test procedure is required to be utilized by the FTC for labeling requirements and shall be 

utilized or referenced by other organizations, such as the EPA for its ENERGY STAR 

specification for TVs. This test procedure must also be referenced by the CEC in California and 

any other state regulation providing for the disclosure of information with respect to any measure 

of TV energy consumption once the test procedure becomes effective 30 days after the test 

procedure final rule publication. The final rule would supersede any existing state test procedure

for TVs to the extent the state regulation requires testing in a manner other than that required by 

the final DOE test procedure. (42 U.S.C. 6297(a)(1))

B. Existing Industry Television Test Procedures 

While developing the proposed test procedure for TVs, DOE researched existing industry

test procedures that measure TV energy consumption, as discussed in its 2010 RFI. 75 FR 54048,

54049. Among the most widely accepted are the IEC 62087-2011 and EPA’s “ENERGY STAR 

Program Requirements for Televisions, Version 5.3” (ENERGY STAR v. 5.3).6 DOE also 

reviewed both the CEA-2037-2009 “Determination of Television Average Power Consumption” 

 

6 ENERGY STAR v. 5.3 references ENERGY STAR v. 4.2; however, for the purposes of the NOPR, all references 

will be made in terms of ENERGY STAR 5.3 although testing was conducted using ENERGY STAR 5.1.

ments.pdf >
18

and the CEC test procedures, and noted that these test procedures are largely based on both the 

EPA and IEC 62087 test procedures. In response to the 2010 RFI, DOE received comments from 

interested parties on what they believed aspects of a robust test procedure should include, as well 

as on the validity of the existing test procedures that DOE reviewed and considered.

Several interested parties expressed general concerns and made suggestions pertaining to 

what should be considered when DOE developed its proposed test procedure. Consumer 

Electronics Retailers Coalition (CERC) expressed desire for a standardized test procedure and 

standard that are reflective of consumer use and that will not increase the cost of equipment. 

CERC further stated that a patchwork of state regulations, mandating different test procedures 

for energy consumption, different standards, or different labels, will confuse consumers with 

conflicting or unclear information, and ultimately be counterproductive. (CERC, No. 10 at p. 1) 

CERC urged DOE to adopt a single federal test procedure for TV energy consumption, because

it will better inform the public and better show energy savings. (CERC, No. 10 at p. 2) Natural 

Resources Defense Council (NRDC) asked that DOE develop a test procedure that allows 

flexibility for policy makers when setting standards such as allowing policy makers to require 

testing at different pre-set picture settings and establishing desired luminance ratios. (NRDC, No. 

5 at p. 1) Pacific Gas and Electric (PG&E) and a joint comment submitted by Southern 

California Gas Company, San Diego Gas and Electric Company, and Southern California 

Edison, henceforth referred to as “California Investor Owned Utilities (IOUs),” expressed desire 

for a test procedure that accounts for all current and future TV technologies. (PG&E, No. 12 at p. 

1; California IOUs, No. 9 at p. 1) Finally, Sony asked that the test procedure provide adequate 

guidance and meaningful power consumption data without forcing manufacturers to perform 

unnecessary, burdensome, and costly activities. (Sony, No. 8 at p. 4)
19

Environment Northeast (ENE) also had general recommendations for DOE’s proposed 

TV test procedure and suggested that the test procedure should be designed so that the test results 

reflect energy consumption in the field to the maximum extent possible. (ENE, No. 2 at p. 1) It

urged DOE to develop a test procedure that only promotes energy management features that 

deliver significant savings in the field. (ENE, No. 2 at p. 1) ENE commented that energy 

consumption should be measured under a range of values (rather than using average values for 

ambient illumination, viewing distances and angles, and user adjustments to settings) and that the 

average expected energy consumption of a model in the field be calculated. (ENE, No. 2 at p. 

1) ENE believes that a test procedure that adheres to its direction will provide more accurate 

results and reduce the likelihood of manufacturers "designing to the test". (ENE, No. 2 at p. 1) 

Finally, ENE urged DOE to design a test procedure that does not discourage innovation. (ENE, 

No. 2 at p. 1)

Other interested parties commented that DOE should use existing test procedures when 

developing its test procedure. NRDC stated that DOE should review and adopt key portions of 

IEC 62087-2008 but noted that aside from the IEC 62087-2008 dynamic broadcast-content video 

signal, the remaining sections of the IEC 62087-2008 test procedure are either incomplete or 

need revision. (NRDC, No. 5 at p. 2) CEA believes that future ENERGY STAR specifications 

should conform to the DOE test procedure, and that CEA-2037-2009 is suitable for adoption 

now with specified discrete changes, although the CEA did not specify these discrete changes. 

(CEA, No. 13 at p. 2) CEA also urged DOE to adopt CEA-2037-2009 to avoid the federal 

government using and promoting two different test procedures. (CEA, No. 13 at p. 3) CERC 

commented that the CEA-2037-2009 test procedure is the best test procedure because it is most 

familiar to manufacturers and retailers and added that it provides a reasonably accurate, 
20

practicable, and cost-effective test procedure. (CERC, No. 10 at p. 2) SHARP urged the DOE to 

utilize IEC 62087-2008 and CEA-2037-2009 as a basis for its test procedure. (SHARP, No. 14 at 

p. 1) Finally, Mitsubishi requested that DOE adopt CEA-2037-2009 as its fundamental TV test 

procedure, and commented that if DOE finds that CEA-2037-2009 test procedure is inadequate,

then it should base its test procedure on IEC 62087-2008. (Mitsubishi, No. 7 at p. 2)

Sony and CEC asked DOE to consider how its test procedure will affect state regulations 

and test procedures. Sony recommended that DOE create a test procedure that supersedes state 

regulations, while CEC believes that DOE should consider how its test procedure will preempt 

CEC's test procedure. (Sony, No. 8 at p. 4) Specifically, CEC urged DOE to measure on mode 

power, standby-passive power, power factor, and luminance to ensure that the CEC can also 

require this testing. (CEC, No. 15 at p. 4)

In addition to considering stakeholder comments, DOE also conducted research and 

validation testing, which consisted of on, standby, and off mode energy consumption testing as 

well as luminance testing. The results of this research indicated that the IEC 62087-2011 could 

be utilized with some modifications as it would adequately measure TV energy consumption7. 

DOE proposes a test procedure for TVs that uses IEC 62087-2011 as a basis, with additional 

detail and modifications, most of which are seen in ENERGY STAR v. 5.3. DOE believes this is 

consistent with the requests of many commenters, who recommended using IEC 62087-2011 and 

CEA-2037-2009, which references the IEC 62087 test procedure. DOE based the proposed 

luminance measurement on the one found in ENERGY STAR v. 5.3.

C. Scope

1. Products Covered by This Rulemaking 

In the 2010 RFI, DOE requested comments on the scope of the TV test procedure 

rulemaking. DOE received comments highlighting the similarities and differences between 

displays, TVs, and digital picture frames and the coverage of the test procedure. Unlike TVs, 

displays and digital picture frames do not have a TV tuner and therefore cannot receive digital 

broadcast content. While all of these technologies have the ability to display digital content they 

do have some differences. DOE notes that these differences are subtle, and therefore considered 

the possibility of including all displays in this rulemaking.

Display and TV technologies have started to converge and have become more similar in 

their capabilities. Given the convergence of display and TV technologies, PG&E, and the 

California IOUs advocated that the coverage of displays be explored in this rulemaking. They

supported DOE's research into whether displays should be incorporated into the test procedure

and specifically stated that DOE should study the category of displays less than 30 inches in 

greater detail as well as displays greater than 60 inches. (PG&E, No. 12 at p. 4; California IOUs, 

No. 9 at p. 4)

Other stakeholders opposed the inclusion of displays in the scope of the rulemaking. 

Sony asserted that TVs and displays are different in the following ways and therefore need to be 

tested differently. TVs have different resolutions than displays because rate conversion circuits 

operate differently in the two products; resolution affects power consumption in displays but not 
22

in TVs; and TVs with computer inputs do not fully comply with the VESA DPMS requirements 

established for displays. (Sony, No. 8 at p. 4) Rather, Sony recommended that DOE use the same 

definition for TVs that is used in the ENERGY STAR v. 5.38. (Sony, No. 8 at p. 4) Panasonic 

also does not recommend combining TVs and displays, as they believe these are two distinct 

products. (Panasonic, No. 6 at p. 9) CERC commented that the scope of the test procedure should 

not encompass all types of TVs because professional and retail displays require high luminance, 

sharpness, and performance. (CERC, No. 10 at p. 3) CERC further commented that displays are 

designed differently than TVs due to their primary use; namely, TVs are meant to be viewed 

from further distances than displays. (CERC, No. 10 at p. 3) Finally, CEA commented that DOE 

should not include displays in its rulemaking because the IEC 62087-2011 dynamic broadcastcontent video signal used for TV testing is not representative of typical content viewed on 

displays. (CEA, No. 13 at p. 9) SHARP recommended that DOE remain focused on TVs that are 

used primarily by residential consumers and that commercial displays should not be included. 

(SHARP, No. 14 at p. 10)

DOE believes that some products can only be identified as TVs or displays on the basis 

of marketing. Some manufacturers (e.g., Samsung and LG) make identical products that are

marketed separately as a display and TV9. Moreover, there exist high-definition displays sold 

with the option of purchasing an external tuner or speakers, which enable the customer to use the 

product as a TV. Modern TVs can also typically be connected to computers and function as 

 

8 ENERGY STAR v. 5.3 defines TV as: A commercially available electronic product designed primarily for the 

reception and display of audiovisual signals received from terrestrial, cable, satellite, Internet Protocol TV (IPTV), 

or other digital or analog sources. A TV consists of a tuner/receiver and a display encased in a single enclosure. The 

product usually relies upon a cathode-ray tube (CRT), liquid crystal display (LCD), plasma display panel (PDP) 

which are examples of the more common display technologies.

monitors. Despite some overlap, DOE agrees with stakeholders who suggested that TVs and 

displays are designed differently in most instances (e.g. TVs are equipped with a tuner and 

displays are not). Although TVs and displays may be used interchangeably, they are designed to 

perform different tasks. Displays have different screen resolutions that allow for clearer text

reading and are typically set up in a 4:3 aspect ratio, as opposed to TVs which are primarily set 

up in 16:9 aspect ratio which is optimal for displaying video. DOE acknowledges that despite the 

increasing overlap between these products, which may increase in the future, they currently have 

different usage patterns (e.g. they are used in different lighting conditions and locations as well 

as have different hours of operation).

The presence of a tuner is not an unequivocal distinguishing factor between TVs and 

other displays; however, DOE still considers it a suitable way of broadly separating products 

which are generally intended to be used as displays or digital picture frames from those generally 

intended to be used as TVs (particularly in the smaller sizes). Accordingly, DOE proposes to 

define TVs with reference to displays but excluding displays if they are sold without tuners. 

Further, DOE believes that this effectively excludes from the proposed TV test procedure most 

displays and digital picture frames currently on the market. 

TVs, unlike displays, often contain a tuner, which historically cost about $5.50 to the 

manufacturer and were projected to cost around $2.70 by the end of 201010. Modern TVs have 

similar inputs to displays, and their uses are increasingly similar, with the latest TVs having USB 

ports, PC inputs, video inputs, Ethernet cable inputs, and inputs enabling connection with

24

cameras and MP3 players (e.g., Samsung, Panasonic, Sony). Moreover, the latest display 

connection technology, High-Definition Multimedia Interface (HDMI), is expressly designed to 

work with both TVs and displays and does not differentiate between the two. DOE is monitoring 

marketplace convergence and will consider updating the definitions and scope of the TV 

rulemaking in the future. 

Consequently, DOE is proposing to include in the scope of this rulemaking only displays 

of 15 inches and above which are sold with a tuner. DOE acknowledges interested party 

comments stating that TVs and displays capable of showing moving images are not similar in all 

ways. However, DOE believes that displays which are sold with a tuner are used in the same 

manner as TVs, and is also taking into consideration that EPA requires displays to be tested with 

IEC 62087 Dynamic broadcast content. DOE welcomes comment on the proposed scope of this 

rulemaking, particularly the inclusion of certain types of displays. (See Issue 1 in section V. E

”Issues On Which DOE Seeks Comment”). 

2. Definition of Television Sets

TVs are a covered product under 42 U.S.C. 6292(a)(12) of EPCA. DOE has the authority 

to adopt test procedures for such covered products under 42 U.S.C. 6293(b)(2) of EPCA. 

Further, 42 U.S.C. 6295(l)(3) of EPCA specifically grants DOE the authority to promulgate

energy conservation standards for TVs. There are no statutory definitions for TVs under EPCA. 

In 1979 DOE adopted the following regulatory definitions for TVs (44 FR 39798, June 29, 

1979), which are set forth in 10 CFR 430.2:

Television set: means a color television set or a monochrome television set.
25

Color television set means an electrical device designed to convert incoming broadcast 

signals into color television pictures and associated sound.

Monochrome television set means an electrical device designed to convert incoming 

broadcast signals into monochrome television pictures and associated sound.

Similar to DOE’s recently repealed test procedure (74 FR 53640, October 20, 2009), the 

current DOE definitions for TVs, developed in 1979, are no longer appropriate and are proposed 

to be updated as part of this rulemaking. The definition refers to both color TVs and 

monochrome TVs (also known as black-and-white TVs, which are rarely produced for the mass 

market today) and with the evolution of technology, these definitions are too broad to adequately 

define the products covered by this rulemaking. Since the digital switch-over in 2009, analog

TVs can no longer receive broadcast signals without an external digital tuner. Accordingly, the 

definitions require updating in order to reflect the realities of modern TVs and technological 

developments, including the convergence of display and TV technology, and to avoid the 

proposed rule being rendered ineffective. 

DOE notes that at the time the Department repealed the test procedure for TVs (74 FR 

53640, October 20, 2009), it also considered amending the definition of TVs on the basis of the 

transition to digital TV and found this factor in isolation to be an insufficient reason to amend the 

definition. At that time, the Department had not taken into account other factors, including, rapid 

technology changes, the changing focus away from transmission towards display technology and 

the phenomenon of TV and display technology convergence. The combination of these factors 
26

which are currently evident in this product market have led DOE to preliminarily determine that 

a revised definition of TVs is required.

CEA asked that DOE develop a definition of TVs that excludes battery-powered TVs

because they inherently are designed for efficiency so as to improve battery life. CEA stated that 

battery-powered TVs are different from typical TVs that require AC or main power supplies in 

their technology and usage patterns. (CEA, No. 13 at p. 9) Additionally, CEA commented that 

displays used for commercial applications and those that fully function on battery-power should 

not be included in the scope of coverage. CEA further observed that portable and handheld 

displays are designed to be power efficient and should therefore not be included in the scope of 

coverage.

In today’s NOPR, after reviewing TV, display, digital picture frame market trends, and 

accessory technologies, as well as other industry definitions from IEC, EPA, and CEA, DOE is 

proposing an updated definition for TVs; one that it believes will not become obsolete with rapid 

changes in technology. Accordingly, a broad technology-neutral definition is proposed that 

includes all TVs and displays above 15 inches which are sold with a TV tuner. This definition

also includes products that incorporate internal media readers (e.g. TV DVD combination units) 

while excluding laptop monitors, monitors having integrated computers (all-in-one integrated 

desktops), digital picture frames, and TVs operable by battery-power. The exclusion of these 

products is based upon DOE’s belief that these products do not represent the typical TV usage

and therefore should not be included in this definition. DOE has determined the typical TV usage 
27

as a product that is commonly used seven hours a day11 to watch dynamic visual information.

Consequently, DOE proposes the following definition to subpart A of 10 CFR 430.2:

Television set (also referred to as “TV”): A product designed to be powered primarily by 

mains power having a diagonal screen size of fifteen inches or larger that is 

manufactured with a TV tuner, and that is capable of displaying dynamic visual 

information from wired or wireless sources including but not limited to: 

(1) Broadcast and similar services for terrestrial, cable, satellite, and/or broadband 

transmission of analog and/or digital signals; and/or 

(2) Display-specific data connections, such as Video Graphics Array (VGA), 

Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI),

DisplayPort, used typically for a computer or workstation that is not physically

attached to the display; and/or 

(3) Media storage devices such as a USB flash drive, a memory card, or a DVD; 

and/or 

(4) Network connections, usually using Internet Protocol, typically carried over 

Ethernet or WiFi.

28

A TV may contain, but is not limited to, one of the following display technologies: liquid 

crystal display (LCD), light-emitting diode (LED), cathode-ray tube (CRT), and plasma 

display panel (PDP). TVs also include TV Combination Units that DOE has further 

defined in appendix H to subpart B of this part.

DOE notes that this proposed definition also includes TV combination units which are 

TVs that incorporate additional devices such as a digital video disc (DVD) player, Blu-ray 

player, hard disk drive (HDD), or videocassette recorder (VCR).These products maintain the 

general purpose of a TV but are combined with additional features.

3. Other Definitions

DOE’s proposed test procedure for TVs incorporates definitions from IEC 62087-2011

and ENERGY STAR v. 5.3. DOE is also proposing to add its own definitions, which were 

neither addressed by IEC 62087-2011 nor ENERGY STAR v. 5.3, and feels the proposed 

definitions are necessary.

Specifically, DOE proposes to include the following defined terms found in IEC 62087-

2011: “additional functions,” “off mode,” “standby-active, high mode,” “standby-active, low

mode,” and “standby-passive mode.” DOE is aware that section 42 USC 6295(gg)(1) of EPCA 

defines on, standby, and off modes, but believes that the proposed IEC 62087-2011 definitions 

provide added clarification to the test procedure. Second, DOE proposes to include the following 

defined terms found in ENERGY STAR v. 5.3: “download acquisition mode,” “luminance,” “on 

mode,” and “TV combination unit.” For the reasons discussed below, DOE also proposes to 

develop new definitions for “home picture setting” and “retail picture setting.”
29

a. Definitions Incorporated from IEC 62087-2011

DOE is proposing to define “additional functions” using the definition found in IEC 

62087-2011. DOE is proposing to define “additional functions” because many TVs are now 

equipped with a wide variety of features, such as DVD players, memory card readers, music 

player inputs, that are not standard among different manufacturers and models. Furthermore, 

DOE believes that this definition from IEC 62087-2011 is appropriate because it is clear, concise 

and widely accepted as an industry definition. The definition for additional functions found in 

IEC 62087-2011 also has not been redefined by any of the later published TV industry standards. 

Accordingly, DOE is proposing to define this term in section 2.1 (additional functions) of 

appendix H to subpart B of 10 CFR part 430 as follows:

Additional functions: Additional functions are functions that are not required for the basic 

operation of the device. Additional functions include, but are not limited to a VCR unit, a 

DVD unit, a HDD unit, a FM-radio unit, a memory card-reader unit, or an ambient 

lighting unit.

DOE is proposing to define “off mode” using the definition found in IEC 62087-2011,

rather than the definition provided in ENERGY STAR v. 5.3. Although ENERGY STAR v. 5.3 

also defines off mode, DOE believes the definition is too broad. Specifically, the ENERGY 

STAR v. 5.3 definition requires that an indicator be present that shows that the product is in off 

mode, a clause that is not included in the IEC 62087-2011 definition. Accordingly, DOE is 

proposing to define this term in section 2.9 (off mode) of appendix H to subpart B of 10 CFR 

part 430 as follows:
30

Off mode: Off mode is the mode where the appliance is connected to a power source,

produces neither sound nor picture and cannot be switched into any other mode with the

remote control unit, an external or internal signal.

DOE is proposing a test for standby-passive mode in this NOPR and thus provides a 

definition for the mode. DOE is proposing to define “standby-passive mode” by using the IEC

62087-2011 definition for standby-passive. This standby-passive mode test is being proposed to 

capture the energy consumption associated with the TV when it produces neither sound nor 

picture. DOE believes that IEC has clearly and appropriately defined standby-passive mode. 

DOE is proposing to define this term in section 2.12 (standby-passive mode) of appendix H to 

subpart B of 10 CFR part 430 as follows:

Standby-passive mode: Standby-passive mode is the mode in which the appliance is

connected to a power source, produces neither sound nor picture but can be switched into 

another mode with the remote control unit or an internal signal.

DOE is proposing to define “standby-active, high mode” consistent with the IEC 62087-

2011 definition for standby-active, high. IEC’s definition clearly and accurately captures the 

state of the TV while in standby-active, high mode. DOE is proposing a definition for standbyactive, high, since DOE is also proposing a test in the standby-active, high mode. Standby-active, 

high mode would cover TVs when they are switched off with a remote, but remain active in 

some manner. This includes TVs that are downloading information from the internet or cable 

while switched into standby mode. Accordingly, DOE is proposing to define this term in 
31

section 2.13 (standby-active, high mode) of appendix H to subpart B of 10 CFR part 430 as 

follows:

Standby-active, high mode: The appliance is connected to a power source, produces

neither sound nor picture but can be switched into another mode with the remote control 

unit or an internal signal and can additionally be switched into another mode with an

external signal and is exchanging/receiving data with/from an external source.

DOE is proposing to define “standby-active, low mode” consistent with the IEC 62087-

2011 definition for standby-active, low. Although DOE is not proposing a test in the standbyactive, low mode, DOE is still proposing a definition for standby-active, low to remain consistent 

with IEC 62087-2011 and to ensure that this particular mode is not tested. DOE has reviewed 

existing industry definitions, TV technology, and TV operating modes and believes that IEC 

62087-2011 clearly separates distinct TV operating modes and defines each of these modes 

appropriately. Standby-active low mode would cover TVs when they are switched off with a 

remote and can be switched into other modes via an external signal. Accordingly, DOE is 

proposing to define this term in section 2.14 (standby-active, low mode) of appendix H to 

subpart B of 10 CFR part 430 as follows:

Standby-active, low mode: The appliance is connected to a power source, produces

neither sound nor picture but can be switched into another mode with the remote control 

unit or an internal signal and can additionally be switched into another mode with an

external signal.
32

b. Definitions Incorporated from ENERGY STAR v. 5.3

DOE proposes to include a definition for “download acquisition mode” (otherwise known 

as DAM) in its test procedure that is identical to the definition found in ENERGY STAR v. 5.3. 

The DAM involves a TV’s download of data while it produces neither sound nor picture. The

definition allows readers to more clearly understand the DAM energy consumption test 

procedure. The energy consumption associated with DAM is measured when the TV is 

downloading information from an electronic program guide (EPG). DOE also believes that the 

ENERGY STAR v. 5.3 definition is appropriate because it is a widely accepted industry 

definition and the term is not defined in IEC 62087-2011. Accordingly, DOE is proposing to 

define this term in section 2.3 (download acquisition mode) of appendix H to subpart B of 10 

CFR part 430 as follows:

Download acquisition mode: Download acquisition mode is the power mode in which the 

product is connected to a mains power source, produces neither sound nor picture, and is 

actively downloading data. Data downloads may include channel listing information for 

use by an electronic programming guide, TV setup data, channel map updates, firmware 

updates, monitoring for emergency messaging/communications or other network 

communications.

DOE is proposing to define “luminance” by incorporating the definition found in 

ENERGY STAR v. 5.3. DOE believes that the ENERGY STAR v. 5.3 definition is appropriate 

because it is widely accepted within the industry and the term is not defined in IEC 62087-2011. 

Further, the ENERGY STAR v. 5.3 definition is appropriate because DOE is proposing the 

luminance ratio so that it may be used in the ENERGY STAR test procedure. The ENERGY 
33

STAR v. 5.3 definition is clear and concise and provides the manufacturer with a thorough 

understanding of what is meant by luminance to allow for luminance testing. Accordingly, DOE 

is proposing to define this term in section 2.8 (luminance) of appendix H to subpart B of 10 CFR 

part 430 as follows:

Luminance: Luminance is the photometric measure of the luminous intensity per unit 

area of light traveling in a given direction, expressed in units of candelas per square meter 

(cd/m2).

DOE is proposing to define “on mode” using the definition found in ENERGY STAR v. 

5.3, rather than the definition provided in IEC 62087-2011. ENERGY STAR v. 5.3 defines “on 

mode” more broadly, stating that the TV can be providing “one or more of its primary 

functions.” On the other hand, the IEC 62087-2011 definition specifies that the TV must be 

producing both sound and picture. Although many TVs will produce sound and picture, DOE’s 

proposed scope may include units that are not able to produce sound (e.g. computer monitor that 

does not include speakers). Because DOE does not want to prevent those products from being 

tested in the “on mode”, DOE is proposing to exclude any references to sound consistent with

the definition from ENERGY STAR v. 5.3 in section 2.10 (on mode) of appendix H to subpart B 

of 10 CFR part 430 as follows:

On mode: On mode is the power mode in which the product is connected to a mains 

power source, has been activated, and is providing one or more of its principal functions.
34

DOE is proposing to define “TV combination unit” using the definition found in 

ENERGY STAR v. 5.3. IEC 62087-2011 defines multi-function equipment, which may be 

considered similar to TV combination unit, but this term is not specific to TVs. Defining the term 

TV combination unit provides clarity to the test procedure since these particular TVs may require 

special consideration when being tested. Accordingly, DOE is proposing to define this term in

section 2.16 (TV combination unit) of appendix H to subpart B of 10 CFR part 430 as follows:

TV combination unit: TV combination unit is a television in which the TV and one or 

more additional devices (e.g., DVD player, Blu-ray Disc player, Hard Disk Drive) are 

combined into a single enclosure, and which meets the following criteria: a) it is not 

possible to measure the power of the individual components without removing the 

product housing; and b) the product connects to a wall outlet via a single power cord.

c. New Definitions for Incorporation

DOE is proposing to define “home picture setting” in its test procedure. DOE developed 

this definition because neither IEC 62087-2011 nor ENERGY STAR v. 5.3 provides a definition 

for this particular setting. ENERGY STAR v. 5.3 does reference a home mode (or default mode), 

as the mode in which the TV is shipped. In order to eliminate confusion between picture settings 

and testing modes (such as on mode, standby mode, and off mode), defining home picture setting 

helps clarify how to conduct both the luminance and on mode tests since home picture setting is 

utilized for conducting part of the luminance test as well as the on mode test. DOE believes that

defining home picture setting will improve the consistency in which products are tested across 

labs. DOE is proposing to define this term in section 2.4 (home picture setting) of appendix H to 

subpart B of 10 CFR part 430 as follows:
35

Home picture setting: (or default picture setting) is the picture setting which is 

recommended by the manufacturer from the initial set up menu or the mode that the 

television comes shipped in if no setting is recommended.

Finally, DOE is proposing to define “retail picture setting” in its proposed test procedure. 

Retail picture setting is a picture setting present on most TVs and corresponds to the brightest 

preset selectable picture setting. Although ENERGY STAR v. 5.3 uses the term retail mode in its 

specification, it does not provide a definition of this mode. So as not to confuse picture settings 

with testing modes (such as on mode, standby mode, and off mode), DOE is proposing to utilize

the term “retail picture setting” instead of the term “retail mode”. In the proposed DOE test 

procedure, retail picture setting is one of the two picture settings that the TV is set to for 

luminance testing. Therefore, DOE believes that defining retail picture setting clarifies the

requirements of the test procedure. DOE is proposing to define this term in section 2.11 (retail 

picture setting) of appendix H to subpart B of 10 CFR part 430 as follows:

Retail picture setting: is the preset picture setting in which the TV produces the highest 

luminance during the on mode conditions.

D. Testing Conditions and Instrumentation

1. Accuracy and Precision of Measurement Equipment 

a. Power Supply

In this NOPR, DOE is proposing a slightly modified version of the power supply 

specifications from IEC 62087-2011. DOE proposes to limit the input voltage and frequency 

used in its test procedure to 115 V at 60 Hz, rather than including a general requirement that the 
36

TV be tested at “the nominal voltage of the region,” as in IEC 62087-2011. DOE is also 

proposing to add a power factor measurement requirement. The power factor measurements are 

based on those found in IEC 62087-2011 as well as ENERGY STAR v. 5.3.

DOE is also proposing certain specifications for test tolerances. First, DOE is proposing 

to incorporate tolerances for voltage and frequency identical to those in ENERGY STAR v. 5.3, 

which specifies that the voltage and frequency be maintained at ± 1 percent rather than ± 2 

percent, as required by IEC 62087-2011. DOE believes that this will not impose undue burden 

because many interested parties are already accustomed to these more stringent specifications 

required to meet ENERGY STAR specifications. Second, DOE is proposing to add a tolerance of 

power measurements consistent with that in ENERGY STAR v. 5.3. As mentioned above, 

ENERGY STAR v. 5.3 refers the reader to ENERGY STAR v. 4.2 where these specifications 

can be found. Third, DOE is proposing to add the requirements for total harmonic distortion 

(THD) consistent with that in IEC 62087-2011, which requires that the harmonic components not 

vary by more than 5 percent. While ENERGY STAR v. 5.3 has requirements for THD that are 

more stringent (2 percent), DOE believes that these requirements may impose undue burden on 

manufacturers by requiring the purchase of more expensive equipment. DOE believes that the 

cost of more expensive equipment (e.g., a power supply unit as found by market research) 

outweighs the benefits of stricter THD requirements, therefore less stringent requirements are 

being proposed. DOE believes that the requirements that it is proposing to incorporate are

accepted within industry and are sufficient to ensure a repeatable and reproducible test 

procedure. THD impacts the quality and stability of the electricity being received by the TV 

which can impact energy consumption. High levels of THD can increase current draw on TVs 

resulting in high circuitry temperatures and inefficiencies. The language proposed to ensure that 
37

the correct power is being supplied to the TV is being incorporated in section 3.1.1 (power 

supply) of appendix H to subpart B of 10 CFR part 430 is as follows:

Carry out measurements using a power supply providing voltage of 115 V at 60 Hz..

The fluctuation of the voltage supplied during the tests shall not exceed ± 1 percent. The 

frequency fluctuation and the harmonic components of the supplied power shall not 

exceed ± 1 percent and 5 percent respectively.

b. Power Meter

DOE is proposing to incorporate specifications for the power meter used to collect the 

power data for the TV test. DOE plans to slightly modify the specification found in IEC 62087-

2011 to include more guided instructions on the sampling rate. Rather than setting the sampling 

rate “high enough to achieve an accurate measurement” as required in IEC 62087-2011, DOE is 

proposing that samples be taken once per second or more frequently. This sampling rate is 

generally accepted by the industry and found in IEC 62301-2011. This sampling rate should not 

be difficult to accomplish and produces a more repeatable power measurement than the 

measurement specified in IEC 62087-2011. Specifying the proposed sampling rate decreases the 

chances of missing trends and power spikes. The duration of testing remains the same and 

typically only a few changes to the data acquisition program are required to modify the sample 

rate. The language proposed to ensure that the correct power measurements are taken is being 

incorporated in section 3.1.2 (power meter) of appendix H to subpart B of 10 CFR part 430 is as 

follows:
38

The measurement shall be carried out directly by means of a wattmeter, a wattmeter with 

averaging function, or a watt-hour meter, by dividing the reading by the measuring time. 

For TVs for which the input video signal varies over time, use a wattmeter with an 

averaging function to carry out the measurement.

The language proposed to ensure that the correct sampling rate for which the power 

measurements shall be taken is being incorporated in section 3.1.2.1 of appendix H to subpart B 

of 10 CFR part 430 is as follows:

The sampling rate of the watt-hour meter or wattmeter with averaging function shall be 

one measurement per second or more frequent. 

The language proposed describing the power measurement uncertainty is being 

incorporated in section 3.1.2.3 of appendix H to subpart B of 10 CFR part 430 is as follows:

Power measurements of 0.5 W or greater shall be made with an uncertainty of less than 

or equal to 2 percent (at the 95 percent confidence level). Measurements of power of less 

than 0.5 W shall be made with an uncertainty of less than or equal to 0.01 W (at the 95 

percent confidence level). The power measurement instrument shall have a resolution of:

• 0.01 W or better for power measurements of 10 W or less;

• 0.1 W or better for power measurements of greater than 10 W up to 100 W;
39

• 1 W or better for power measurements of greater than 100 W.

DOE is also proposing to require that, as part of the test procedure, the power factor of 

the TV be recorded while in “on mode” consistent with that in ENERGY STAR v. 5.3. DOE 

believes that requiring a power factor measurement will not impose undue burden on 

manufacturers because the ability to measure power factor is widely available on power meters. 

The power factor measurement only requires that the power factor be recorded while the on, 

standby, and off modes are measured. DOE is proposing to require this measurement because 

power quality can impact energy consumption and measuring the power factor will allow other 

regulating bodies the flexibility to consider requirements for power quality. The language 

proposed to ensure that the power factor and real power consumed are taken is being 

incorporated in section 3.1.2.2 of appendix H to subpart B of 10 CFR part 430 is as follows:

The power measurement instrument used shall measure the power factor and the real 

power consumed regardless of the power factor of the device under test.

c. Light Measurement Devices

i. Luminance Contact and Distance Meters

Light measurement devices (LMDs) are used to measure the luminance of the TV screen. 

DOE is aware of two primary categories of LMDs that are used to make luminance 

measurements: contact meters and distance meters. In response to the 2010 RFI, DOE received 

comments advocating that the DOE test procedure for TVs allow the use of the contact meter to 

measure luminance. Panasonic stated that although there are many valid methods of 

measurement, a contact measurement is easier to comply with since it prevents ambient light 
40

from interfering with the measurement and eliminates the need for a dark room. (Panasonic, No. 

6 at p. 4) NRDC also supports the contact method of measuring luminance as it simplifies the 

performance of the test due to it being unnecessary to adjust the room lighting levels. (NRDC, 

No. 5 at pp. 4--5)

In this NOPR, DOE is proposing to allow the use of either a distance meter or a contact 

meter to measure luminance for purposes of the DOE test procedure, so long as the meter meets 

the specifications detailed in section III.D.1.c.ii of the NOPR. DOE is aware that each type of 

meter has specific advantages. While distance LMD meters are typically less accurate and 

require the use of a dark room for luminance measurements, they are less expensive than contact 

LMD meters. DOE is also aware that the use of a dark room adds burden to the procedure by 

increasing both cost and set-up time. Alternatively, the use of a contact LMD meter would 

reduce set up time (with regard to both aligning the meter as well as removing the need for a 

dark room) and will have a more accurate measurement since these meters typically have a 

higher accuracy; however, contact meters themselves are more expensive. Through testing, DOE 

has learned that the two types of meters yield similar results when used to test TVs 12. Therefore, 

in section 3.1.3 (light measurement device) of appendix H to subpart B of 10 CFR part 430, the 

test procedure allows the use of either meter as long as it meets the specifications outlined below. 

By allowing the use of different meters it provides more flexibility, while ensuring the accuracy 

of the measurement and providing comparable results. 

 

12 This similarity of results can be found in the Round Robin Test Program Final Report for: Television at the DOE 

website: Appliance and Commercial Equipment Standards: Television Sets. U.S. Department of Energy. August 2, 

2011. <http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html>
41

ii. Light Measurement Device Specifications 

In this NOPR, DOE is proposing to incorporate specifications for the LMDs used in 

performing the test procedure. Neither IEC 62087-2011 nor ENERGY STAR v. 5.3 provides

specific requirements with respect to LMDs. Consequently, DOE has developed proposed 

specifications for today’s NOPR. To develop these, DOE researched existing test procedures and 

standards that provide LMD specifications. DOE has found that the VESA Flat Panel Display 

Measurements Standard v. 2 provides tolerances for LMDs. VESA specifies that the luminance 

must be within ± 5 percent and repeatability must be less than ± 0.5 percent of the luminance or 

the uncertainty introduced by any digitalization over a five minute period. DOE also researched 

available LMDs for testing to develop the following proposed requirements.

DOE is proposing, in section 3.1.3 (light measurement device) of appendix H to subpart 

B of 10 CFR part 430, that all LMDs have an accuracy of ± 2 percent (± 2 digits) of the digitally 

displayed value and repeatability within 0.4 percent (± 2 digits) value. DOE is also proposing 

that the LMD should have an acceptance angle of 3 degrees or less. To determine the precision 

of a measured number, the displayed value on the measuring device needs to be taken into 

consideration. The increment of the last significant digit is said to be the accuracy of the display 

and 2 digits is twice the interval. The overall tolerance of LMDs is found by taking (+/-) the 

absolute sum of 2 percent and 2 significant digits of the measured value.

DOE believes that these criteria are sufficiently stringent to ensure that measurements 

will be repeatable and accurate, without imposing burden on manufacturers by requiring overly 
42

precise measurement devices. However, DOE welcomes comments on the proposed LMD 

specifications. (See Issue 2 in section V.E ”Issues On Which DOE Seeks Comment”).

2. Test Room and Set-Up Criteria

DOE received comments from interested parties requesting that it clarify how to set up 

the TV for testing. Specifically, NRDC requested that DOE review the requirements in IEC 

62087-2008 and urged DOE to provide sufficient clarity on preparing the TV before testing. 

(NRDC, No. 5 at p. 2) DOE has analyzed IEC 62087-2008 as NRDC requested and found that 

the requirements in IEC 62087-2008 are similar to those found in IEC 62087-2011. PG&E and 

California IOUs also requested that DOE require a standard test set-up that ensures the most 

robust results possible. (PG&E, No. 12 at p. 3; California IOUs, No. 9 at p. 3) DOE has analyzed 

both IEC 62087-2011and IEC 62087-2008, and has evaluated other existing TV test procedures 

to develop proposals for creating dark room conditions, ambient temperature and humidity, 

THD, and signal source generation, with the goal of ensuring repeatable results. The proposals 

are discussed in detail in the following sections. 

a. Dark Room Conditions

DOE is proposing that, if the lab technician elects to use a distance meter for luminance 

testing, it must make the measurements in dark room conditions, similar to the requirement in 

ENERGY STAR v. 5.3. DOE is proposing, in section 4.2 (dark room conditions) of appendix H 

to subpart B of 10 CFR part 430, language from the requirement in ENERGY STAR v. 5.3, 

which (with minor modification), states: “All luminance testing shall be performed in dark room 

conditions. Display screen illuminance...as measured with the UUT in [o]ff [m]ode shall be less 

than or equal to 1.0 lux.”
43

b. Ambient Temperature and Humidity 

DOE is proposing ambient conditions consistent with IEC 62087-2011 and ENERGY 

STAR v. 5.3, which both require that ambient temperature be 23°C ± 5° C. ENERGY STAR v. 

5.3 further specifies that relative humidity must be between 10 and 80 percent, which DOE is 

also proposing to require in its test procedure. Because these are both widely accepted test 

methods, and each of the temperate and humidity ranges is quite large, these requirements should 

be reproducible across a wide range of test laboratories. These ambient condition requirements 

are being proposed in sections 4.3 (ambient temperature conditions) and 4.4 (ambient relative 

humidity conditions) of appendix H to subpart B of 10 CFR part 430.

c. Signal Source and Generation

In the 2010 RFI, DOE requested feedback from interested parties regarding the signal 

source as well as the input cable to be used when testing. 75 FR 54048, 54050. As discussed 

below, interested parties were generally in agreement that the input cable should be HDMI, if the 

TV has an HDMI input. If the TV does not have an HDMI input, DOE has proposed a list of 

alternative connections in the order in which they should be used to conduct testing, which can 

be found below. Interested parties were also in support of using a Blu-ray player as the signal 

source for testing. 

Mitsubishi, Sony, LG, NRDC, Panasonic, CEA, CEC, PG&E, and California IOUs were 

all in support of DOE using HDMI as its preferred input cable. Mitsubishi recommended that 

DOE require an HDMI cable be used if the input exists and component cables be used if HDMI 

inputs do not exist. (Mitsubishi, No. 7 at p. 5) Sony similarly commented that a HDMI input 

cable should be the preferred input cable, and if it not available, the next highest resolution input 
44

should be used. (Sony, No. 8 at p. 3) LG supported using an HDMI input cable because it has a 

digital signal and other sources have calibration issues. (LG, No. 3 at p. 1) NRDC recommended 

that DOE use a HDMI input cable if the input is available. If not available, then a component 

input cable should be used. NRDC also stated that VGA connectors should not be allowed to 

serve as the means to input the content. (NRDC, No. 5 at p. 6) Panasonic agreed that a HDMI 

input cable should be used if available. (Panasonic, No. 6 at p. 6) CEA agreed that a HDMI input 

cable should be used if it is available, but stated that variation between different inputs is minor. 

(CEA, No. 13 at p. 7) CEA further commented that it is vital to allow various different input 

cables to be used because some TVs are produced with neither a HDMI input nor a component 

input. (CEA, No. 13 at p. 7) Ecos Consulting found in its previously cited report the effect of 

different input cables on the test results. Their report recommended that an HDMI input cable be 

used for testing because it produced similar results to a standardized signal generator unlike 

component and VGA inputs13.

As outlined above, comments from all interested parties agreed that an HDMI input 

should be the preferred input. Some interested parties also advocated that alternative inputs 

should be allowed if an HDMI input is not available. DOE acknowledges that all TVs may not be 

shipped with an HDMI input available, and therefore is proposing the following order for inputs: 

HDMI/DVI, VGA, component, S-Video, and finally composite. If none of these inputs are 

available, the highest resolution input must be used. DOE believes that by proposing an input 

format hierarchy, it will ensure consistency and repeatability between tests without imposing

Efficiency Test Procedures for Display. (Last accessed July 26, 2011).

45

undue burden upon manufacturers. However, DOE welcomes comments on the purposed input 

formats hierarchy. (See issue 14 in section V.E “Issues on Which DOE Seeks Comments”)

DOE also received comments on the signal source to be used for testing. NRDC 

commented that a signal should not be generated by a personal computer (PC). NRDC preferred 

that a standard method of generating signal be used, but did not specify what the preferred 

method should be. (NRDC, No. 5 at p. 6) Panasonic believes that the Blu-ray player is the most 

appropriate device to supply the IEC 62087-2008 dynamic broadcast-content video signal, which 

is the same as the IEC 62087-2011 dynamic broadcast-content video signal. (Panasonic, No. 6 at 

p. 6) CEC concurs with the recommendations made in the report done by Ecos Consulting 

regarding signal sources, which recommends a signal generator with an HDMI input connection.

(CEC, No. 15 at p. 3) PG&E and California IOUs also cited the report done by Ecos Consulting, 

but commented that DOE should conduct additional testing on various size TVs with different 

display technologies to confirm the proper signal source. (PG&E, No. 12 at p. 3; California 

IOUs, No. 9 at p. 3) SHARP recommended that DOE not require a specific signal source like 

CEA-2037-2009. (SHARP, No. 14 at p. 7) SHARP commented that there should be no 

dependency on the nature of the source (Blu-ray player, computer, etc), as long as the decoder 

and signal are properly implemented according to existing and well-known standards. (SHARP, 

No. 14 at p. 7)

The IEC 62087-2011 dynamic broadcast-content video signal, which is discussed further 

in section III.E.3.a of this NOPR, is supplied in two formats for testing, DVD and Blu-ray. DOE 

acknowledges interested party comments recommending that a particular signal source should 

not be used but believes that establishing a specific signal source will increase repeatability and 
46

reproducibility. As some commenters requested, DOE is proposing to require testing using a 

Blu-ray player. The TV market is moving towards watching TV in high-definition, as evidenced 

by increased production of high definition TVs and broadcasting of high definition channels. 

Blu-ray players produce a 1080p image that yields far more detail than the 480p image provided 

by DVD; therefore, DOE is proposing that it be used for testing. DOE welcomes comments on 

the signal source and generation specifications proposed in this NOPR. (See Issue 3 in section 

V.E ”Issues On Which DOE Seeks Comment”).

E. Test Measurements

As previously mentioned, DOE is proposing a test procedure largely based on IEC 

62087-2011, with some modifications to improve the repeatability as well as tailor the procedure 

to the U.S. market. DOE is proposing that the following test measurements be taken as described 

in the following sections. 

1. Picture Settings to Test 

In the 2010 RFI, DOE requested comment on testing the TV in multiple power 

consuming modes. For luminance testing, ENERGY STAR v. 5.3 requires that the TV be tested 

in two picture settings: home mode and retail mode. As stated earlier, DOE is proposing to 

replace the terms home mode and retail mode (as used in ENERGY STAR v. 5.3) with home 

picture setting and retail picture setting. This is to distinguish the luminance picture setting from 

the testing modes for energy consumption. IEC 62087-2011 does not reference luminance 

testing. Alternatively, for power testing, both IEC 62087-2011 and ENERGY STAR v. 5.3

require that TVs be tested only in the home picture setting. DOE received comments and is 

considering testing energy consumption in picture settings other than the home picture setting.
47

Numerous commenters informed DOE that only a limited number of consumers switch 

their TVs out of the home picture setting, and therefore DOE should only require testing in the 

home picture setting. Other interested parties suggested that DOE analyze all preset picture 

settings to determine the energy consumption of all possible picture settings. Mitsubishi 

commented that manufacturer statistics show that less than 5 percent of TV viewers ever utilize 

non-default display settings. (Mitsubishi, No. 7 at p. 2) PG&E and California IOUs stated that 

DOE should collect and analyze available technologies (e.g., LCD, plasma) in several selectable 

preset picture settings: the dimmest setting, home setting, and retail setting. (PG&E, No. 12 at p. 

1; California IOUs, No. 9 at pp. 1-2) PG&E and California IOUs also urged DOE to develop the 

test procedure such that any preset picture setting may be measured using the procedure. (PG&E, 

No. 12 at p. 2; California IOUs, No. 9 at p. 2) Finally, they suggested that the DOE should obtain 

and analyze data on consumer home viewing habits. (PG&E, No. 12 at p. 2; California IOUs, 

No. 9 at p. 2) SHARP commented that because consumers do not adjust their TV settings and it 

is not possible to predict the popularity of each picture setting, multiple picture settings should 

not be tested. (SHARP, No. 14 at p. 4) 

DOE also received comments desiring that only the home picture setting should be used 

for testing. SHARP stated that there are no reliable data on the popularity of modes that can be 

applied across the industry, and, therefore, the out-of-the-box setting remains the best predictor 

of actual power use. (SHARP, No. 14 at p. 3) Sony commented that there is little information 

regarding consumer preferences for preset picture settings. Sony’s call center data indicates that 

more than 95 percent of returned sets remain in the home picture setting when received, while 

information obtained during CEC's rulemaking process suggests that consumers tend to use the 

home picture setting. (CEC, No. 15 at pp. 2--3 and Sony, No. 8 at p. 2) NRDC commented that 
48

to the extent a TV has a “forced” set up menu; the test should be performed on the TV as shipped

after selecting the home picture setting in the menu. (NRDC, No. 5 at p. 3) CERC believes that 

the test procedure should focus on the energy consumption of TVs in the home picture setting

due to the difference in room lighting and energy consumption of TVs in retail and home 

settings. (CERC, No. 10 at p. 3) CEA commented that DOE should not require testing of other 

preset viewing settings because it is time consuming and will not yield useful information 

because consumer viewing habits are unknown and preset viewing settings are not standard

across manufacturers. (CEA, No. 13 at p. 5) 

In this NOPR, DOE is proposing that luminance measurements be taken in both the home 

and retail picture settings, and that power measurements (for TVs without ABC enabled) only be 

taken in the home picture setting. As many interested parties commented, most consumers do not 

switch their TVs out of the picture setting in which they are shipped. Therefore, requiring power 

measurements in the retail picture setting or any other alternative picture settings may cause 

unnecessary burden on manufacturers by increasing testing time. A luminance measurement in 

both the home and retail picture setting must still be taken in order to generate a luminance ratio, 

which is utilized by other regulatory programs such as ENERGY STAR. However, DOE is also 

considering testing on mode energy consumption in picture settings other than the home picture 

setting. DOE is aware of some TVs that are equipped with remotes that have easy-to-access 

shortcuts that enable the user to switch from the home picture setting to other preset picture 

settings (sport, vivid, movie, etc.), without requiring that the user enter the main menu. Although 

interested parties commented that consumers do not switch between picture settings, DOE 

believes that if TV remotes are designed with shortcuts to switch between preset picture settings, 

more consumers may do so, either accidently or intentionally. For this reason, DOE is 
49

considering whether this should be taken into account in the test procedure. In particular, DOE is 

considering testing on mode energy consumption in some of these additional preset picture 

settings. Possible approaches could include testing in the highest and lowest energy consuming 

preset picture settings, while displaying the IEC 62087-20011 dynamic broadcast-content video 

signal, or the brightest and dimmest preset picture settings. An additional approach could include 

testing in all preset picture settings. DOE invites comments on testing in additional preset picture 

settings, particularly the balance between a representative and not overly burdensome test 

procedure. (See Issue 4 in section V.E ”Issues On Which DOE Seeks Comment”).

2. Testing Order

In today’s NOPR, DOE is proposing to require that testing be conducted in the following 

order: luminance, on mode power, standby mode power, and off mode power tests. This is not 

consistent with the test procedure prescribed in ENERGY STAR v. 5.3, which specifies on mode 

tests be conducted prior to luminance tests. DOE is aware that some TVs are unable to operate in 

the retail picture setting once the TV has been switched into the home picture setting. Therefore, 

it is necessary to measure luminance in the retail picture setting before switching to the home 

picture setting to ensure that the retail picture setting luminance is captured. For this reason, 

DOE is proposing to perform luminance testing prior to on mode power testing in section 5.3.1

(luminance test) of appendix H to subpart B of 10 CFR part 430. DOE does not believe that this 

alternative testing order will increase the testing burden or cause any issues with test results, but 

will ensure that all TVs are adequately tested in each prescribed mode. 

3. Luminance
50

Although IEC 62087-2011 does not include a luminance test, ENERGY STAR v. 5.3

requires a test of the screen luminance. The luminance test is included to ensure that TVs are not 

shipped in an overly dim picture setting in order to achieve a lower measured on mode power 

value, since under ENERGY STAR v. 5.3 TVs are tested in “as shipped” condition. In the 2010 

RFI, DOE asked interested parties for comments on multiple facets of luminance testing. 

Specifically, DOE requested input on (a) whether testing luminance should be required, and (b) 

the different display patterns that can be used to adequately test luminance. 75 FR 54048, 54049. 

Many interested parties provided feedback regarding the need for luminance testing. Several 

interested parties supported luminance testing. NRDC stated that screen luminance is important 

to include in the test procedure because it often has a direct impact on TV on mode power use 

and future energy conservation standards might include these parameters in the rulemaking; thus, 

including a test for screen luminance would allow policy makers the ability to add luminance 

requirements to their standards. (NRDC, No. 5 at pp. 2-3) It further clarified that the luminance 

test method should include details on (a) the video signal being used; (b) the type of instrument 

and its precision; (c) the angle and location of the measurement points; and (d) the ambient 

lighting conditions, if necessary. (NRDC, No. 5 at p. 5) Finally, NRDC stated that it believes the 

DOE luminance testing could require: (a) testing in “as shipped” conditions in home or retail 

picture settings; (b) ability to measure either a luminance ratio or a power ratio; and (c) TVs to 

be set at a specified luminance prior to measurement. (NRDC, No. 5 at pp. 3-4)

LG supported the ENERGY STAR luminance test method, which involves measuring the 

luminance while displaying the IEC 62087-2011 three bar video signal. This test is conducted 

twice, once while the TV is in the home picture setting and again when the TV is in the retail 

picture setting. After both measurements are taken, the ratio of the two luminance measures is 
51

calculated. LG believes that it is an acceptable and representative measure of luminance and 

provides consistency across state and federal programs. (LG, No. 3 at p. 1) SHARP does not 

support luminance testing, but asserts that, if DOE must define a luminance measurement

procedure, it should follow the ENERGY STAR v. 4.1 (which remained unchanged in ENERGY 

STAR v. 5.3) test procedure in detail. (SHARP, No. 14 at p. 5) Similarly, Sony believes that the 

luminance requirement as defined by ENERGY STAR v. 5.3 is an unnecessary test, but finds the 

method itself provides a rather simple solution to a complex subject. (Sony, No. 8 at p. 2)

Alternatively, CEA and some manufacturers strongly opposed requiring a luminance 

measurement, with primary arguments including that default TV picture settings are not too dim, 

and DOE should not regulate a performance metric. CEA stated that a luminance requirement is 

unnecessary, premature and essentially not energy related. (CEA, No. 13 at p. 3) CEA also 

commented that any proposal to impose limits on luminance and/or tie luminance levels to power 

levels is speculative and a performance requirement should not be embedded within the test 

procedure as it may not be authorized by EPCA. (CEA, No. 13 at p. 4) Mitsubishi stated that 

DOE should not set standards that assure that products meet a certain consumer utility. 

(Mitsubishi, No. 7 at p. 3) CEA noted that DOE should not include a luminance requirement, but 

if a luminance test is included it should mirror the test outlined in ENERGY STAR v. 4.1

(which, as noted above, remained unchanged in ENERGY STAR v. 5.3). (CEA, No. 13 at p. 4) 

According to CEA, data indicates that consumers maintain the default settings of the TVs, and,

therefore, retail picture settings are not relevant to those consumer viewing habits. (CEA, No. 13 

at p. 3) Sony also commented that, after thoroughly reviewing its call center data, it found no 

complaint of dim pictures, which was DOE’s reasoning for including a luminance test. (Sony, 

No. 8 at p. 1) Sony commented that the test procedure should measure power and should not be a 
52

luminance test procedure. (Sony, No. 8 at p. 4) Mitsubishi commented that manufacturers will 

not produce TVs with dim home picture settings, because this would create poor reviews and 

high return rates. Mitsubishi further believes it is undesirable for manufacturers in this industry

to sell a TV that is too dim because there are very tight margins. (Mitsubishi, No. 7 at p. 2) 

Panasonic believes that a regulation on luminance is not required since manufacturer competition 

discourages the shipping of dim TVs. (Panasonic, No. 6 at p. 1) Panasonic affirmed that the 

luminance testing in ENERGY STAR v. 5.3 was adopted as a solution to prevent only the remote 

possibility of the TVs being shipped too dim. (Panasonic, No. 6 at p. 2)

SHARP stated that DOE should not specify a luminance measurement and observed that 

the 65 percent home to retail ratio required by ENERGY STAR specifications may be 

encouraging TVs to have a brighter home picture setting than they otherwise would. SHARP did 

not believe that setting a lower bound for luminance would address the issue of shipping a TV 

too dim to decrease its power consumption for home mode testing. (SHARP, No. 14 at p. 3) 

SHARP wrote that IEC did not set luminance requirements because manufacturers will not ship 

overly dim TVs and risk product returns. Additionally, SHARP commented that there is no 

consensus on how to measure brightness levels, and setting a lower bound on home mode 

brightness is a performance requirement rather than an energy requirement. (SHARP, No. 14 at 

p. 2) SHARP further noted that if performance requirements force minimum luminance levels to 

be set too high, potential energy savings are lost. (SHARP, No. 14 at p. 3) Lastly, SHARP

commented that any static video signal can be detected and circumvented, and therefore DOE 

should not implement a luminance measurement. (SHARP, No. 14 at p. 3) It stated that IEC 

62087-2008 (which is the same as IEC 62087-2011) was not based on prescribed luminance 

levels for the following reasons: 
53

1) Consumers generally do not adjust their TVs from the default settings, 

2) Relatively few consumers have their TVs professionally calibrated, 

3) There is no consensus on how to measure perceived brightness levels,

4) Perceived brightness is often related to contrast ratio as it is related to pure brightness, 

5) Some TV technologies have a non-linear relationship between power and brightness, 

6) Variation in consumer illuminance levels make the ideal brightness difficult to 

determine, and 

7) Humans have poor acuity for discerning absolute brightness levels, and there is no data 

that identifies the level of brightness to which the average person would adjust a 

television by hand. (SHARP, No. 14 at p. 2) 

In this NOPR, DOE is proposing to include a luminance test as part of its test procedure.

In recognition of interested parties’ concerns, DOE clarifies that the proposed luminance test is 

included in the test procedure solely for the purpose of supporting the ENERGY STAR program; 

the Department is not proposing to include the luminance measurements in its final metrics for 

measuring the energy efficiency or consumption of TVs. Including a luminance test as part of the 

test procedure for TVs will allow other programs such as ENERGY STAR to utilize the results. 

The sections, below, describe the different aspects of this proposal, as well as comments from 

interested parties on these aspects.

a. Warm-up and Stabilization 

As mentioned in section III.E.2, above, DOE is proposing to require that luminance tests 

be conducted prior to on mode testing. Due to the change in luminance testing order (conducting 
54

testing in the retail picture setting prior to the home mode picture setting), DOE considered both

warming-up the TV with respect to power and stabilizing the TV for luminance. However, in 

today’s notice, DOE is proposing that the TV be warmed-up but not be stabilized prior to 

measuring display luminance.

IEC 62087-2011 and ENERGY STAR v. 5.3 both require that the TV be warmed-up 

prior to energy measurement but do not include a recommended or minimal time period. Rather, 

they state that energy measurements be taken “after the TV has achieved a stable condition with 

respect to power consumption.” With respect to luminance testing, ENERGY STAR v. 5.3

requires the three bar video signal be displayed for 10 minutes to stabilize a TV prior to 

conducting a measurement. DOE received comments from interested parties on the appropriate 

time required to warm-up and stabilize a TV prior to conducting testing. 75 FR 54048, 54051

Mitsubishi commented that measurements of power consumption should be taken after 

the TV has reached normal operating temperature. (Mitsubishi, No. 7 at p. 5) Mitsubishi further 

commented that warm-up times vary by model and it is difficult to identify a minimally 

sufficient warm-up time, but it is also unnecessary. It continued by adding that it is sufficient to 

require that before testing begins, the device under test has reached thermal equilibrium, and that 

the test procedure need not indicate a specific time but rather a minimum. (Mitsubishi, No. 7 at 

p. 6) PG&E and California IOUs stated that the warm-up time should be sufficient to reflect realworld conditions while also aiming not to be too long so as to become overly burdensome. 

(PG&E, No.12 at p. 3; California IOUs, No. 9 at p. 3) SHARP, Sony, Panasonic, and CEA 

recommended that DOE refer to the IEC 62087-2008 test procedure for warm-up periods. The 
55

warm-up periods remained unchanged in IEC 62087-2011. (SHARP, No 14 at p. 7; Sony, No. 8 

at p. 3; Panasonic, No. 6 at p.7; CEA, No. 13 at p. 7)

DOE acknowledges all stakeholder comments and is proposing to incorporate language 

that the TV be warmed-up consistent with that in IEC 62087-2011, with the addition of a 

minimum warm-up period requirement. In this NOPR, DOE is proposing TVs be warmed-up 

using the IEC 62087-2011 dynamic broadcast-content video signal for at least one hour in 

section 5.2 (warm-up) of appendix H to subpart B of 10 CFR part 430. DOE conducted testing to 

determine if this warm-up was appropriate14. Although the power did not change drastically over 

the one hour for any of the TVs tested, DOE believes that because no interested party 

commented on the desire to reduce the duration, a one hour warm-up period was still 

appropriate. DOE will further propose that the TVs can be warmed-up for longer than one hour if 

the TV does not reach a stable state with respect to power consumption within the one hour time 

period. DOE is defining a stable state as an average power measurement over the 10 minute test 

clip that varies by less than 2 percent on consecutive plays. DOE believes that by establishing a 

minimum warm-up period, the test results will be more consistent, because all TVs will be 

warmed up for an identical time period. Further, DOE testing indicates that the majority of TVs 

will stabilize within one hour. DOE also consulted with industry subject matter experts15 who 

had similar findings16. Although DOE plans to specify that a one hour warm-up period be used,

document which can be found on the DOE website: Appliance and Commercial Equipment Standards: Television

there is flexibility to utilize a longer warm-up period for the TV to reach a stable energy 

consuming state. For luminance stabilization, DOE is not proposing that the TV be stabilized 

prior to conducting luminance measurements, rather that luminance measurements be taken 

immediately upon displaying the three bar video signal. Luminance measurements are made 

immediately to prevent automatic image correction programs from revising the luminance of the 

observed test pattern.

DOE received a comment from Panasonic recommending that DOE adopt the luminance 

measurement test procedure in ENERGY STAR v. 5.3, which requires that luminance be 

measured immediately following the on mode test, ensuring that the TV is sufficiently stabilized 

with respect to power prior to conducting the luminance test. Panasonic also stated that it does

not object to increasing the 10 minute stabilization periods if it is felt to be necessary. 

(Panasonic, No. 6 at p. 7) No other interested parties commented on the topic.

ENERGY STAR v. 5.3 requires that the TV display the three bar video signal for 10 

minutes prior to conducting a luminance measurement. As part of today’s NOPR, DOE is 

proposing to require that luminance measurements be taken immediately after displaying the IEC 

62087-2011 dynamic broadcast-content video signal from the warm-up period in section 5.4.1 of 

appendix H to subpart B of 10 CFR part 430. DOE conducted extensive research to determine 

the appropriate stabilization period and has preliminarily determined that taking luminance 

measurements immediately after displaying the IEC 62087-2011 dynamic broadcast-content

video signal is the most technology neutral method17. DOE’s research also found that the 

luminance of some TV technologies drops as the same image remains on the screen and 

luminance with other TV technologies increases as the same image remains on the screen18. 

Taking an immediate measurement helps to mimic actual operating conditions, in which images 

are changing constantly.

Specifically, taking measurements according to this method ensures that TVs, particularly 

plasmas, do not enter into an automatic brightness limiting (ABL) state prior to luminance 

testing. ABL is a technology that is used on phosphor based TV screens (CRT and plasma) that 

is designed to limit the luminance of the screen to a level that will avoid damage to the 

phosphors. This type of protection is not necessary in LCD technology as high luminance levels 

cannot cause damage to the display elements. Measuring the luminance immediately after 

displaying the IEC 62087-2011 dynamic broadcast-content video signal, without allowing a 

substantial period of delay, will ensure that TVs do not require additional stabilization time while 

displaying the IEC 62087-2011 three bar video signal which would result in some TVs entering 

an ABL state. This method will promote more consistent testing across products. Taking 

measurements according to this method also ensures that TVs, particularly LCDs with cold 

cathode fluorescent lamp (CCFL) technology, have been stabilized. DOE welcomes comments 

on the stabilization and warm-up periods proposed in this NOPR. (See Issue 6 in section V.E

”Issues On Which DOE Seeks Comment”).

b. Method for Testing Luminance 

As mentioned above, many TVs have multiple preset viewing settings. Again, the retail 

picture setting is typically used in showrooms, whereas the home picture setting is intended to be 

more suited for typical home viewing conditions. ENERGY STAR v. 5.3 uses a luminance ratio 

test that compares these two picture settings. However, DOE is aware of alternative methods for 

ensuring that the TV does not have an overly dim home picture setting such as power ratios and 

absolute luminance measurements, and therefore in the 2010 RFI, DOE requested feedback on 

testing by using luminance ratios, power ratios and absolute luminance. 75 FR 54048, 54049.

Many commenters believed that power cannot be measured to determine the brightness of 

the TV. Panasonic commented that the relationship between power and luminance is often nonlinear and is highly variable between TV technologies, specifically in TVs with "local dimming" 

and "power on demand". Panasonic believes that this non-linear relationship makes a power ratio 

an unfair measurement of screen brightness. Panasonic believes that the measurement of the 

power would not result in the goal of determining whether a TV is "too dim.” (Panasonic, No. 6 

at p. 2) Panasonic commented that though they recognized all of DOE’s concerns pertaining to a 

luminance ratio, they support its inclusion in the test procedure. (Panasonic, No. 6 at p. 2) 

Mitsubishi commented that different display technologies have different luminance and power 

characteristics, and these two aspects of TVs should not be conflated. Mitsubishi also noted that

luminance variation across the screen is unrelated to energy consumption. (Mitsubishi, No. 7 at 

p. 2) Mitsubishi also believes that measuring power rather than a luminance ratio does not satisfy 

the "goal" of preventing manufacturers from producing devices that are not useful in the home 

picture setting. (Mitsubishi, No. 7 at p. 3) Finally, Mitsubishi commented that some TV display 
59

technologies have a power consumption that correlates significantly with the content displayed 

rather than the display luminance. (Mitsubishi, No. 7 at p. 3) SHARP stated that a fixed 

luminance level is not prescribed for power measurements made with CEA-2037-2009 and IEC 

62087-2008 (nor in IEC 62087-2011), and therefore DOE does not need to implement a 

luminance measurement. (SHARP, No. 14 at p. 3) Sony also does not support measuring power 

consumption at prescribed luminance levels or picture settings. Sony believes that picture 

settings are performance settings and are not directly tied to luminance. (Sony, No. 8 at p. 2)

CEC presented an alternative method for using power to ensure the TV is not shipped in 

an overly dim picture setting. CEC suggested that a power ratio be taken between home and 

retail picture settings. The home picture setting would be used for compliance when the ratio was 

closer to one, while a weighted result of home and retail picture settings power would be used as 

the power deviates from one. (CEC, No. 15 at p. 2) NRDC suggested that DOE improve the 

ENERGY STAR luminance test by establishing a minimum screen luminance for all presets in 

the set up menu. The method would require the lab technician to record the screen brightness that 

was measured prior to running the on mode power test with the IEC 62087-2008 dynamic 

broadcast-content video signal, which is the same as the IEC 62087-2011 dynamic broadcastcontent video signal. (NRDC, No. 5 at p. 4) NRDC also urged DOE to ensure that all 

measurements for ratios should be made identically. (NRDC, No. 5 at p. 5)

SHARP also suggested an alternative method for ensuring that TVs are shipped in a 

picture setting that satisfies consumer viewing desires. SHARP commented that DOE should set 

a requirement based on a “floor,” which would be a fixed percentage of the power of the most 

consumptive setting, and recommends that the floor be 40 percent of the most power consuming 
60

setting. This approach will help ensure that home picture setting is not overly dim as well as cap 

the maximum power consumption of a TV regardless of the picture setting. (SHARP, No. 14 at 

p. 5) SHARP supports the maximum power ratio approach, given that the allowable home to 

retail picture settings power ratio is no more than 40 percent. SHARP believes that unlike the 

luminance ratio approach, which is a performance requirement, setting a threshold for reported 

power is part of the power measurement process. (SHARP, No. 14 at p. 3) P.R. China suggests 

implementing an efficiency ratio of the output power and input power that includes luminance in 

the nominator, multiplied by the screen size, and divided by the input power. (China, No. 16 at p. 

3)

PG&E, California IOUs, and CEC requested a flexible test procedure with respect to 

luminance. PG&E and California IOUs recommended that the test procedure be designed so that 

policy-makers could consider luminance or power ratios between different preset picture 

settings. (PG&E, No.12 at p. 2; California IOUs, No. 9 at p. 2) CEC urged DOE to adopt a test 

procedure which includes both power and luminance testing at a minimum picture setting and the 

retail picture setting, but provides enough flexibility that the policy makers can decide how these 

numbers are used to set standards. (CEC, No. 15 at p. 2)

Interested parties also offered comments discouraging the possible inclusion of an 

absolute luminance measurement. Panasonic believes that absolute luminance does not provide 

enough data to determine if the TV is providing a "satisfactory consumer viewing." Panasonic

noted that many TV calibrators and video post production engineers consider the contrast ratio to 

be more important than absolute luminance. (Panasonic, No. 6 at p. 2) Panasonic also 

commented that when measuring luminance, the method must provide accurate results across all 
61

technologies, which is much easier with a ratio than with absolute luminance measurements. 

(Panasonic, No. 6 at p. 2) Finally, Panasonic commented that using a relative ratio is more 

tolerant of non-calibrated luminance meters, measurement distances and angles and the 

measurement location because the error cancels out between the two measurements. (Panasonic, 

No. 6 at p. 3) 

In this NOPR, DOE is proposing measuring luminance to allow the ENERGY STAR 

program to utilize the measurement in section 5.3.1 (luminance test) of appendix H to subpart B 

of 10 CFR part 430. As mentioned in section III.E.1 above, DOE is proposing to test the TV in 

home and retail picture settings. DOE is proposing to include a luminance ratio, as is done in 

ENERGY STAR v. 5.3. DOE believes that by taking a ratio, less error is introduced than if 

taking an absolute luminance measurement. Further, ratios have been used in many other TV 

efficiency measures. For example, ENERGY STAR v. 5.3 requires that home picture setting 

shall not be less than 65 percent of the peak luminance of the retail picture setting. The European 

Parliament requires a luminance ratio of at least 65 percent in the Commission Delegated 

Regulation (EU) No 642/2009. Australia’s government requires a 50 percent luminance ratio in 

AS/NZS 62087.2.2:201. Although DOE does not currently intend to include the luminance 

measurements in its final metrics for measuring energy efficiency or consumption, testing for a 

luminance ratio will allow DOE’s TVs test procedure to support the requirements of the

ENERGY STAR Program and allow other regulating bodies to include a luminance ratio in their 

test procedures. DOE invites comments on luminance testing and including a luminance ratio.

(See Issue 5 in section V.E ”Issues On Which DOE Seeks Comment”).
62

c. Video Signals

To test luminance, ENERGY STAR v. 5.3 requires that a static video signal be displayed, 

and a measurement be taken using an LMD. In the 2010 RFI, DOE asked for comments on the 

use of two video signals: the IEC 62087-2008 three bar video signal, which is the same as the 

IEC 62087-2011 three bar video signal, and the Chinese TV test procedure’s nine point video 

signal (hereafter referred to as the nine point video signal). 75 FR 54048, 54050. As mentioned, 

IEC 62087-2011 does not require luminance testing, whereas ENERGY STAR v. 5.3 requires 

that a single luminance measurement be taken while the TV is displaying the three bar video 

signal. 

DOE believes that an ideal TV luminance video signal should represent actual broadcast 

content as closely as possible so that the measured luminance is an accurate reflection of the 

luminance produced under real-world operating conditions and is technology-neutral. DOE 

recognizes that it is possible that an ideal video signal may vary depending on the purpose for 

which it will be used. DOE envisions that the three bar luminance video signal proposed in 

today’s NOPR would be used as part of a luminance ratio. The table below lists the various video 

signals that DOE is considering as well as their perceived advantages and disadvantages. It 

should be noted that a number of stakeholder comments appear to equate the number of white 

areas in the video signal with the number of measurements. DOE wishes to clarify that these are 

two separate issues (for example, the nine point video signal could be used to test at anywhere 

between one and nine points); the number of measurements and related test burden are discussed 

in a following section. Any of the following video signals could be measured at a single point or 

multiple points. 
63

Three key features of plasma TV technology impact the brightness of white areas on their 

screens. These features, therefore, need to be taken into consideration in evaluating and selecting 

an appropriate technology-neutral video signal. Most plasma technology TVs limit brightness for 

very bright parts of the screen. As mentioned above, this feature called ABL is intended to 

protect the screen. Although the intention of ABL is to protect the screen, ABL functions 

differently across TVs. The protection is, however, generally based on the size of the bright area. 

For very small areas such as tiny spots seen on firework displays, ABL is likely to have little 

effect and the spots, therefore, will be very bright. The larger the white area, the more ABL tends 

to be applied. The second type of protection is when a static picture is detected with bright (and 

maybe not so bright) areas. After several minutes of a static image the brightness may be 

decreased to try to eliminate phosphor image burn. The third protection mode operates when the 

whole screen is bright: to protect plasma drive circuits, the power, and thus also the luminance,

tend to be limited. What is being observed is the image burning protection.

DOE recognizes that none of the video signals currently under consideration is ideal. 

Each has advantages and disadvantages which are described below. Until a markedly improved 

video signal is made available, DOE is not inclined to change the status quo. DOE understands 

that IEC is contemplating a pattern with a dynamic video signal which may have significant 

advantages. DOE supports IEC’s development of this potentially improved pattern and would 

consider incorporating it in future TV test procedures.

DOE received comments on each of the video signals (see sections, below), described 

above as well as alternative suggestions for luminance testing, including the number of 

measurements to take while displaying a particular video signal. In response to commenters’

concerns, DOE considered multiple video signals when developing its NOPR. DOE considered 

the three bar, the nine point, and a DOE developed dynamic video signal. In this NOPR, DOE is 

proposing to test luminance using the three bar video signal in section 5.3.1.2 (three bar video 

signal measurement) of appendix H to subpart B of 10 CFR part 430, but is also considering 

using the other two signals.

i. Three Bar Video Signal

The three bar video signal was developed by the IEC and published in the third edition of 

its TV broadcast transmission test procedure, IEC 60107-1997 Ed. 3.0 “Methods of measurement 

on receivers for TV broadcast transmissions - Part 1: General considerations - Measurements at 

radio and video frequencies.” The three bar video signal is found in IEC 62087-2011, and is used 

to measure luminance in ENERGY STAR v. 5.3. It is the most widely used video signal for 

measuring luminance. The three bar video signal produces three equidistant vertical white bars 

on a black background. The width of each of these bars is 1/6 of the nominal horizontal width of 

the picture. The three bar video signal has an APL of 50 percent. A higher APL can cause some 

plasma TVs to enter more quickly into a power limiting state to prevent screen burn-in caused by 

displaying a bright screen for an extended period of time.

In response to the 2010 RFI, many commenters expressed desire for DOE to use the three 

bar video signal for testing luminance. CERC, CEA, Sony, Mitsubishi, and Panasonic supported 
66

the use of the three bar video signal. (CERC, No. 10 at p. 3; CEA, No. 13 at p. 4; Sony, No. 8 at 

p. 2; Mitsubishi, No. 7 at p. 3; Panasonic, No. 6 at p. 3) Mitsubishi believes that the three bar 

video signal is adequate. (Mitsubishi, No. 7 at p. 4) Sony commented that the 3-bar test pattern is 

used in IEC and ENERGY STAR test procedures. Changing it will add complexity to an already 

complex subject. (Sony, No. 8 at p. 2) CEA stated that DOE should institute the ENERGY 

STAR test method of using the three-bar measurement procedure. (CEA, No. 13 at p. 4)

Panasonic supports the use of the 3 bar pattern, as it is used by ENERGY STAR, CEA, CEC, and 

Australia. (Panasonic, No. 6 at p. 3)

Conversely, SHARP commented that the three bar video signal is ineffective for plasma

TVs, giving an advantage to the technology and is not necessarily “unpredictable for LED 

backlit TVs,” as DOE stated in the 2010 RFI. (SHARP, No. 14 at p. 4) 

Although DOE is proposing that luminance testing be conducted with the three bar video 

signal, DOE acknowledges that there are drawbacks associated with its use. The APL of the 

three bar video signal is 50 percent, which is greater than that of typical broadcast content. The 

three bar video signal also does not have a reference point to vertically center the luminance 

meter readings which requires additional time to establish where the measurement should be 

taken. Another drawback to the three bar video signal is a static video signal which is not 

representative of typical TV program content. The final disadvantage to the three bar video 

signal is that it results in a quick ABL for plasma TVs due to the amount of white space on the 

screen. Although, the three bar video signal has disadvantages, DOE is currently unaware of a 

truly technology neutral video signal that isn’t affected by the type of TV technology. Video 

signals can have differing affects on TV technologies resulting in higher power consumption in 
67

some technologies and lower power consumption in other technologies. Because the three bar 

video signal is the current industry standard, it is used as a basis for comparison for the other 

video signals considered in the sections below.

ii. Nine Point Video Signal

The nine point video signal is used in the Chinese TV test procedure ICS 27.010. The 

video signal was developed to measure variations in luminance across the screen and account for 

local dimming. This video signal consists of nine white rectangular boxes symmetrically 

arranged in a three by three grid. The nine point video signal is also a static video signal which 

does not improve upon the current three bar video signal and can also result in some ABL for 

plasma TVs. The average APL for the nine point video signal is 17 percent which is lower than 

typical broadcast content. (P.R. China, No. 16 at p. 3) Because the nine point video signal has a 

lower APL than the three bar video signal, it alters the luminance ratio between home and retail 

picture settings for some TVs which would force policy makers to alter their respective 

luminance ratio requirements. DOE found that at least four different plasma TVs, which would 

have met ENERGY STAR requirements for luminance ratio with the three bar video signal, had 

a ratio below 65 percent when displaying the nine point video signal.

Panasonic discouraged DOE from using the nine point video signal and Digital Video 

Essential (DVE) window (a VESA industry video signal) because Panasonic believes these 

patterns do not prevent some TVs from power limiting; therefore they are not technology neutral. 

Panasonic did not provide any comment on how the video signals impact the TV’s power 

limiting. (Panasonic, No. 6 at p. 4)
68

Alternatively, P. R. China recommended that DOE utilize the nine point video signal 

because the APL is 17 percent, it is technology neutral, and it accounts for non-uniform screen 

luminance. (P.R. China, No. 16 at p. 3)

DOE conducted various tests utilizing the nine point video signal. After interpreting data,

the absolute luminance values obtained while using the DOE nine point video signal were 

generally higher in the retail picture setting and lower in the home picture setting than those 

obtained while using the three bar video signal, particularly in plasma TVs. DOE believes these 

results can be attributed to the lower APL of the nine point video signal, which prevents the TV 

from quickly entering ABL. This video signal might than disproportionately disadvantage 

plasma TVs. DOE also determined that changing the video signal will also impact the luminance 

ratio. Due to the change in absolute luminance values obtained while using the DOE nine point 

video signal, luminance ratios generally decreased for plasma TVs when compared to displaying 

the three bar video signal. DOE did not find any other major trends in size or brand for the TVs 

in which the ratio differed when using the nine point video signal as opposed to the three bar 

video signal. Due to the reasons stated above, DOE has determined not to propose utilizing the 

nine point video signal in this NOPR.

iii. DOE Five Point Video Signal

As mentioned above, DOE developed a five point video signal that has an APL identical 

to typical consumer broadcast content (34 percent). This video signal is based largely on the 

VESA five point video signal and consists of five white rectangular boxes arranged with one box 

in the center of the screen and one box in each corner.
69

Upon testing, DOE found that the absolute luminance values obtained while using the 

DOE five point video signal were generally lower than those obtained while using the three bar 

video signal. DOE believes these results are due to the fact that the five measurements took into 

account the perimeter of the screen which is typically dimmer than the center. Similar to the nine 

point and the VESA five point video signal, this can also be attributed to the location of the 

measurements taken, as the center of the screen is typically brighter than the edges. With testing, 

DOE determined that this video signal also displayed some ABL for some plasma TVs 

regardless of the fact that the APL is 34 percent. DOE did not find any major trends in size or 

brand for the TVs in which the ratio differed when using the DOE five point video signal as 

opposed to the three bar video signal other than changes in the luminance ratio for some TVs.

iv. DOE Dynamic Video Signal

Finally, DOE is interested in the development of a video signal that it believes may be 

more representative of actual consumer use, and may be more technology neutral. A technology

neutral video signal was requested by numerous interested parties in response to DOE’s 2010 

RFI. 

Some interested parties expressed a general desire for a technology neutral video signal 

or one that has an APL more similar to the IEC 62087-2008 dynamic broadcast-content video 

signal, which is the same as the IEC 62087-2011 dynamic broadcast-content video signal. PG&E 

and California IOUs encouraged DOE to develop a video signal that has an APL that is more 

similar to the IEC 62087-2008 dynamic broadcast-content video signal than the three bar video 

signal. This will help ensure that the luminance measurements are more reflective of actual TV 

usage. (PG&E, No.12 at p. 2; California IOUs, No. 9 at p. 2) PG&E and the California IOUs also 
70

commented that the video signal should not favor one type of display technology over another. 

(PG&E, No.12 at p. 2; California IOUs, No. 9 at p. 2) Panasonic agreed that the goal of a 

technology neutral video signal is certainly appropriate, though they feel that such a pattern has 

been elusive. (Panasonic, No. 6 at p. 3) NRDC encourages DOE to track the IEC development 

effort that is in progress, because IEC may be considering a potentially more technology neutral 

video signal including the nine point video signal used in China. (NRDC, No. 5 at p. 4) Finally, 

CEC supported DOE’s investigation to identify a suitable video signal and recommends one that 

has an APL close to that of the IEC 62087-2008 dynamic broadcast-content video signal. (CEC, 

No. 15 at p. 2) P. R. China agrees that an alternative video signal with an APL more similar to 

the IEC 62087-2008 dynamic broadcast-content video signal should be developed. (P.R. China, 

No. 16 at p. 3) P.R. China suggests that TVs be adjusted using the “8-gray scale mode” and then 

be tested using the nine point video signal. (P.R. China, No. 16 at p. 3) 

Panasonic also suggested alternative language found in the EuP 642/200920 to conduct 

luminance testing. The EuP 642/2009 allows for different video signals for various TV 

technologies and only specifies that the video signal must be a “full screen,” which does not 

exceed the APL point where power limiting occurs. (Panasonic, No. 6 at p. 3) Panasonic 

commented that the European Union recognizes that each technology has a different, non-linear 

methodology for determining the brightness of individual images and therefore has prescribed 

different video signals for various technologies to meet the criteria of having a video signal that

is not "power limiting" or dimming the screen as more pixels are required to be illuminated. 

 

20 Directive 2005/32/EC of the European Parliament and of the Council with regard to ecodesign requirements for 

televisions <http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2009:191:0042:0052:EN:PDF>
71

Panasonic believes that both of these methods are also valid approaches of measuring luminance. 

(Panasonic, No. 6 at p. 3) 

Alternatively, Mitsubishi commented that the APL is irrelevant to the goal of measuring 

luminance, which is to determine if the home picture setting luminance is overly dim. 

(Mitsubishi, No. 7 at p. 3)

To address interested party comments, DOE’s subject matter experts21 have 

recommended development of a video signal that simulates the apparent brightness of a picture 

as well as an APL similar to the IEC 62087-2011 dynamic broadcast-content video signal. The 

proposed video signal would consist of a black rectangle (with an APL of zero percent) and a 

white rectangle (with an APL of 100 percent) placed at the center of the IEC 62087-2008 

dynamic broadcast-content video signal. These rectangles will maintain the video signal’s APL 

at approximately 34 percent, which is similar to typical broadcast content. Each rectangle would 

be approximately 1 x 1 inch for a 26 inch TV. The purpose of the small size of the rectangles is 

to minimize the overall impact they have on the APL of the video signal but allow for a white 

section to measure the luminance. Also, to help ensure that the TV does not detect the squares as 

stationary objects, the squares will alternate places with each other every minute.

DOE hopes that this video signal will not unfairly benefit any specific technology, 

because it will simulate the state that the TV enters when displaying the IEC 62087-2011

dynamic broadcast-content video signal. This video signal may also prevent the TV from APL,

72

because it is a dynamic video signal which neither the three bar nor nine point video signal are 

capable of preventing.

In summary, DOE understands the issues associated with the three bar video signal as 

well as all static video signals, but is utilizing the three bar video signal as the tentative default 

video signal for this NOPR while it continues to investigate other video signals and receive 

comments about them. Although DOE is proposing to require the three bar video signal, it would 

appreciate any comments on measuring luminance while displaying either the nine point or 

dynamic video signal that DOE also considered for incorporation in this rulemaking. (See Issue 7

in section V.E ”Issues On Which DOE Seeks Comment”).

d. Number of Luminance Measurements

In addition to the particular video signal displayed during luminance testing, the number 

of measurements and how those measurements are taken is important. In the 2010 RFI, DOE 

asked for comments on a nine point test measurement versus a single point test measurement. 75 

FR 54048, 54050. Given the interested party feedback and additional testing discussed below, 

DOE is proposing to only require a single point luminance measurement.

In response to the 2010 RFI, many commenters expressed desire for DOE to only require 

one luminance measurement if a luminance measurement is required. Mitsubishi stated that the 

variation of luminance across the screen, which they believe is the purpose of measuring 

multiple points while displaying the nine point video signal, does not relate to the goal of 

ensuring that TVs do not have a home picture setting that is overly dim. Mitsubishi added that, 
73

for this reason, taking nine measurements using the nine point video signal adds unnecessary 

burden. (Mitsubishi, No. 7 at p. 4) Sony believes that using a video signal other than the three bar 

video signal and measuring multiple points will add complexity to an already complex subject. 

(Sony, No. 8 at p. 2) Panasonic commented that the nine point video signal offers no benefit over 

the three bar video signal, noting that a nine points measurement requires more time, is more 

difficult to perform, and is less repeatable. (Panasonic, No. 6 at p. 3) Sony similarly stated that 

manufacturers in China suggested that measuring luminance while utilizing the nine point video 

signal is lengthy and complex when measuring multiple points, and it does not provide more 

meaningful energy information than measuring a single point, though Sony did not explicitly 

state which Chinese manufacturers provided this comment. (Sony, No. 8 at p. 2) CEA also 

strongly opposed replacing the single point luminance measurement with the nine point video 

signal measurement, because taking nine measurements adds burden without giving more 

meaningful results. (CEA, No. 13 at p. 5) SHARP believes that a single point measurement is 

adequate for a ratio test. SHARP added that the Chinese test procedure uses a nine point video 

signal since it outputs an absolute luminance. (SHARP, No. 14 at p. 4) SHARP commented that 

a nine point video signal measurement is much more expensive than a single, centered 

measurement. (SHARP, No. 14 at p. 4) 

Other commenters urged DOE to adopt a luminance test that required multiple 

measurements, rather than a single measurement as currently required in ENERGY STAR v. 5.3. 

PG&E and California IOUs recommended DOE collect and analyze data using multiple point 

video signals to account for variations of luminance levels on different areas of a screen. (PG&E, 

No.12 at p. 2; California IOUs, No. 9 at p. 2) PG&E and California IOUs acknowledged that 

adding a multiple measurement video signal will add test variation; however, they believe that 
74

luminance measurements from multiple points may be needed. (PG&E, No.12 at p. 2; California 

IOUs, No. 9 at p. 2) NRDC did not specify a particular video signal to be used, but they prefer a 

method that requires multiple measurements rather than a single measurement. (NRDC, No. 5 at 

p. 4)

DOE conducted testing with the nine point video signal in order to determine the 

drawbacks and benefits of measuring luminance at multiple locations compared to measuring at 

only one point. Testing using this video signal was conducted using two separate methods: 1) 

perpendicularly realigning the LMD to the center of each of the nine white squares (hereinafter 

referred to as the DOE nine point method); and 2) aligning the LMD perpendicularly with the 

center white square, maintaining the LMD fixed position, and angling the meter to measure eight 

off-axis white squares (hereinafter referred to as the Chinese nine point method). A distance 

luminance measurement is required to test off-axis measurements, but both a distance and 

contact meter can be used to take the perpendicular measurements. These nine measurements can 

be averaged to arrive at the overall screen luminance, ensuring that the brightness across the 

entire screen is accounted for in the measurement. Although the results for individual points 

varied across the screen when measuring luminance at multiple locations, DOE notes that 

measuring the additional locations would not impact the luminance ratio as the ratio would 

remain similar between TVs. DOE found that each of the individual measurement points across 

the TV screen maintained a similar ratio in the home and retail picture setting. DOE therefore 

believes that its proposed method of measuring luminance at a single location is sufficient for 

this test procedure. DOE’s test results show that the ratio from the average of the nine locations 

and only the central location are exactly the same on all but one TV tested which had ratios that 
75

were within three percent22. Because luminance is calculated as a ratio, multiple location 

measurements serve to decrease the measurement accuracy and repeatability of measurement. 

In summary, DOE is proposing that only one luminance measurement be taken in each 

home and retail picture setting in section 5.3.1.2 (three bar video signal measurement) of 

appendix H to subpart B of 10 CFR part 430. Taking multiple measurements, specifically with a 

distance meter, greatly increases the test burden and this burden outweighs the potential benefits 

of measuring multiple locations around the screen. Measuring only one location will also 

harmonize the DOE test procedure with other TV test procedures that manufacturers currently 

use to evaluate products. Although DOE is proposing to only require one luminance 

measurement per picture setting, DOE is seeking comments on taking a single measurement 

versus multiple measurements when testing for luminance, along with any testing data that 

supports or refutes DOE’s proposed method.

e. Measurement Distances and Angles for Luminance Testing

In the 2010 RFI, DOE considered requiring that luminance measurements be taken at 

various distances and angles, rather than perpendicular to the center of the screen as required by 

ENERGY STAR v. 5.3. 75 FR 54048, 54050. However, after further investigation and input 

from interested parties, DOE is proposing that luminance measurements be taken perpendicular 

to the center of the screen, similar to the approach in the ENERGY STAR test procedure.

 

22 The luminance ratio data indicates that the ratio from any one particular location (regardless of location) is similar 

between home and retail settings. This data can be found on the DOE website: Appliance and Commercial 

Equipment Standards: Television Sets. U.S. Department of Energy. August 2, 2011. 

<http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html>
76

PG&E and California IOUs believe that the angle needs to be specifically defined and 

that a perpendicular angle may be appropriate; they also recommend that DOE acquire test 

results using different angles to inform the decision. (PG&E, No. 12 at p. 2; California IOUs, No. 

9 at p. 2) Sony questioned the need to measure at angles and the benefits it provides in a test 

procedure, stating that the optimal distances to take luminance measurements are described in the 

LMD specifications. (Sony, No. 8 at p. 2) Similarly, Panasonic recommended that a single 

luminance measurement be taken perpendicular to the center of the screen. (Panasonic, No. 6 at 

p. 4) They believe that the contrast will vary with the room ambient light and the viewing angles. 

(Panasonic, No. 6 at p. 2) CEA also stated that the measurement distances and angles are not as 

important as making the measurements in a consistent manner. (CEA, No. 13 at p. 5) P.R. China 

measures luminance from a distance of three times the height of a high-definition TV screen and 

four times the height of a standard display TV screen because it simulates consumer viewing 

conditions. (P.R. China, No. 16 at p. 4) Finally, SHARP commented that luminance 

measurements at various distances and angles would only be appropriate if absolute luminance 

measurements were the goal. (SHARP, No. 14 at p. 4) SHARP also commented that a 

perpendicular measurement is adequate, if a luminance measurement is required. (SHARP, No. 

14 at p. 4) SHARP stated that the correct distance for the measurement is dictated by the 

measurement tool, rather than the TV. (SHARP, No. 14 at p. 4)

Taking nine perpendicular measurements using a distance measure greatly increases 

testing burden as it requires that the meter be aligned nine times, once for the measurement of 

each white square. The Chinese nine point method also increased burden as it requires nine 

measurements rather than a single one. Although the luminance meter only needs to be 
77

positioned once, the additional off-angle measurements still increase the burden of the test 

method. In addition, the Chinese nine point method eliminates the ability to use a contact LMD.

As stated, above, DOE is proposing that luminance measurements be taken perpendicular 

to the center of the screen in section 5.3.1.1 (LMD setup) of appendix H to subpart B of 10 CFR 

part 430. DOE believes that measuring multiple locations on off-axis angles will add 

unnecessary variation to measurements made, will likely reduce the repeatability of the test and 

increase testing time. DOE is also proposing that the distance for which these measurements are 

taken are in accordance to the set specifications for the luminance measurement device, which 

can be found in III.D.1.c.ii of this NOPR.

4. On Mode

DOE is proposing to use the IEC 62087-2011 on mode test procedure. This test 

procedure displays the widely accepted IEC 62087-2011 dynamic broadcast-content video signal

while the TV is in the on mode. Consistent with ENERGY STAR v. 5.3, DOE is considering 

testing on mode differently depending on whether ABC is enabled or disabled when the TV is 

shipped. If the TV is shipped with ABC enabled by default, the TV would be tested at multiple 

room illuminance levels, and if the TV is without ABC enabled by default, it would only be 

tested in the home picture setting. However, DOE wishes to continue to encourage 

manufacturers to ship TVs with ABC enabled. Although DOE is proposing to measure on mode 

without being connected to the internet, DOE is also interested in receiving feedback on 

potentially measuring on mode while the TV is connected to the internet. See section 11 of this 

NOPR.
78

a. IEC 62087-2011 Dynamic Broadcast-Content Video Signal

IEC 62087-2011 and ENERGY STAR v. 5.3 both require the use of the IEC 62087

dynamic broadcast-content video signal for on mode testing, which is the same in both the 2008 

and 2011 versions of the test procedure. This video signal displays a variety of clips that have an 

average APL equivalent to typical broadcast content. DOE received a comment from NRDC 

supporting the use of the IEC 62087-2008 dynamic broadcast-content video signal. (NRDC, No. 

5 at p. 2) Although no other interested party explicitly stated that the IEC 62087-2011 dynamic 

broadcast-content video signal should be incorporated, no interested party opposed the use of the 

video signal. Moreover, a number of parties suggested that the clip should be the basis for any 

3D test procedure, affirming its wide acceptance. In this NOPR, DOE is proposing that the IEC 

62087-2011 dynamic broadcast-content video signal be used to measure on mode energy 

consumption in 2D mode on all TVs. 

b. Testing of Television Sets Shipped with Automatic Brightness Control Enabled 

ABC is a power saving feature in which the TV automatically adjusts the screen 

luminance to account for the ambient lighting conditions (room illuminance). IEC 62087-2011 

and ENERGY STAR v. 5.3 require TVs with ABC enabled by default to be tested differently 

than those without ABC enabled by default. DOE requested comment on the method for testing 

TVs with ABC enabled by default, as well as which room illuminance levels are most 

appropriate for testing. 75 FR 54048, 54050.

Interested parties were generally in support of DOE adopting a test procedure for TVs 

with ABC enabled by default. PG&E and California IOUs commented that appropriate 
79

implementation of an ABC feature for TVs could result in significant energy savings. (PG&E, 

No. 12 at p. 2; California IOUs, No. 9 at p. 2) PG&E and California IOUs urged DOE to adopt a 

repeatable and representative method for measuring energy consumption of TVs with ABC 

enabled by default, stating that this should be a key area of focus for DOE. (PG&E, No. 12 at pp. 

2-3; California IOUs, No. 9 at pp. 2-3) PG&E and California IOUs have observed that the on 

mode power consumption reported to EPA drops by an average of 24 percent when testing with 

the ABC feature enabled. They obtained this data by comparing 18 specific TV models that did 

not have the ABC feature enabled on the August 2010 EPA product list, but did have it enabled 

on the September 2010 list. (PG&E, No. 12 at p. 3; California IOUs, No. 9 at p. 3) NRDC also 

supported the inclusion of a method to test TVs with ABC enabled by default, stating that when 

designed properly, the ABC feature can provide low cost means of delivering significant energy 

savings. (NRDC, No. 5 at p. 5) NRDC further commented that many TVs have ABC as a means 

to comply with the new, more stringent ENERGY STAR 4.1 specifications as well as standards 

in California and elsewhere that are also likely to be effective soon. (NRDC, No. 5 at p. 5) Sony 

commented that the IEC 62087-2008 and ENERGY STAR v. 4.1 use the proper method to 

measure ABC energy consumption, and in the absence of a better method, DOE should adopt the 

same method. (Sony, No. 8 at pp. 2 -- 3) This same method is used in IEC 62087-2011 and 

ENERGY STAR v. 4.3. SHARP believes that ABC scaling factors should continue to encourage 

adoption of a default-on ABC feature. (SHARP, No. 14 at p. 6) Panasonic commented that due to 

tremendous variability between TV manufacturers and individual models, it is difficult to 

measure the performance of the ABC features of TVs. (Panasonic, No. 6 at p. 5) Finally, CEA 

informed DOE that it will consider changes to ABC testing in the next revision of CEA-2037-

2009 and will propose any change to DOE. (CEA, No. 13 at p. 6)
80

DOE agrees with the interested parties that are in support of incorporating TVs with ABC 

enabled by default in a test procedure. Although some interested parties disagree with the current 

method of measuring ABC energy savings, the majority of them agreed that testing TVs with

ABC enabled by default was appropriate. DOE therefore is proposing to incorporate a test 

procedure for TVs with ABC enabled by default in section 5.4 (on mode test for TVs without 

ABC enabled by default) of appendix H to subpart B of 10 CFR part 430. The sections below 

provide details relating to room illuminance levels and the method for creating test room 

illuminance for purposes of measuring energy consumption of TVs enabled with ABC.

i. Test Room Illuminance Levels and Associated Television Luminance Levels

ENERGY STAR v. 5.3 and IEC 62087-2011 require that ABC energy consumption be 

measured at two test room illuminance levels, 0 lux and greater than 300 lux. As mentioned in 

the 2010 RFI, a 2009 study conducted by Ecos Consulting discovered that ABC is often 

implemented in a manner that may not take full advantage of the potential energy savings23. In 

particular, if implemented incorrectly, ABC may achieve significant energy savings at the 

expense of TV picture quality, reducing the likelihood that users will actually enable the feature 

and achieve the claimed energy savings. The study showed that some TVs reduce the brightness 

of their displays at 0 lux, and then increase the brightness significantly at room illuminance 

levels only slightly above 0 lux. Since both IEC 62087-2011 and ENERGY STAR v. 5.3 only 

measure energy consumption at the mentioned two luminance levels, the TV seems to consume 

less energy than it does in use, causing results that are not representative of actual use. DOE also

performed testing with respect to this issue and rarely observed any kind of gradual change in

screen luminance in response to changes in room illuminance24.

DOE conducted testing in mid-2011 on multiple TVs representing various manufacturers, 

display technologies, and screen sizes to understand how TV luminance varies with changes in 

room illuminance when ABC is enabled. These measurements largely confirm those recently 

conducted by the Collaborative Labeling and Appliance Standards Program (CLASP25), 

revealing that some TVs increase their screen luminance in a steady, continuous fashion as 

room illuminance increases (models D and L in 1 below).

DOE’s testing shows that other TVs with ABC operate in a more binary fashion (models 

K and M in 1 below), holding luminance largely constant until room illuminance becomes quite 

low, and then dropping their luminance dramatically. This behavior is likely a consequence of 

the way ENERGY STAR currently provides an energy savings credit to TVs with ABC enabled 

by default, since ENERGY STAR currently only measures at 0 and 300 lux, and not at any 

intermediate points.

 

24 The energy consumption at different illuminance levels while ABC is enabled can be found on the DOE website:

Sample data from DOE’s testing are shown in 1. DOE has provided the full data set for 

this testing on its website26. 

Figure 1: Screen Luminance at 0, 10, 30, 50, 100, 150, and 300 lux

DOE has also determined that a significant number of TVs that currently implement ABC 

do so in a way that yields unusually low screen luminance values (less than 50 nits) when room 

illuminance is at 10 lux or less. Display experts recommend a minimum luminance for dark room

83

viewing conditions of approximately 80 to 137 nits.27 Very low luminance levels help to reduce 

energy consumption, but may yield a display that is so dim that users would want to disable ABC 

or modify room lighting conditions in order to cause the display to operate at a higher luminance 

level. In either case, much of the desired energy savings from ABC operation would be lost.

As a result, DOE is seeking comment from stakeholders regarding whether there should 

be a limit to the reduction in display luminance achieved from ABC, and how a minimally 

acceptable display luminance value should be established. DOE also received a number of 

comments on the appropriate room illuminance levels at which to conduct testing. 

CEC, PG&E and California IOUs encouraged DOE to continue to research room 

illuminance conditions that are representative of consumer homes. CEC supports improvements 

to ABC testing, and believes that more appropriate lighting levels can be derived from 

Illuminating Engineering Society of North America (IESNA) studies. (CEC, No. 15 at p. 3) 

PG&E and California IOUs urged DOE to collect and analyze luminance and power data with 

and without ABC enabled with a range of room illuminance levels typical of consumer viewing 

conditions. (PG&E, No. 12 at p. 3; California IOUs, No. 9 at p. 3)

Although some manufactures suggested that 0 lux should be changed, manufacturers 

were generally opposed to altering the room illuminance levels at which the TV is tested.

Mitsubishi believes that measuring power at two levels of illuminance and assuming a linear 

 

27 The minimum luminance to which CNET calibrates televisions for optimal viewing in a dark room is 137 nits. 

See http://reviews.cnet.com/how-we-test/tv/. The Imaging Science Foundation (ISF) recommends a similar 

minimum luminance for dark room viewing conditions. Televisions with an ISF Expert display mode tested by 

DOE operated at a minimum luminance in that mode of 100 to 130 nits. Televisions with a THX display mode 

tested by DOE operated a minimum luminance in that mode of 80 to 95 nits. 
84

relationship between the values is an approximation at best. (Mitsubishi, No. 7 at p. 5) They 

continued by adding that measuring at four illuminance points (e.g. 0, 10, 100, and 200 lux) 

doubles the testing burden on the lab making the measurement and does not ensure a linear 

relationship between any of the two points or necessarily make the power consumption 

approximation significantly better. (Mitsubishi, No. 7 at p. 5) NRDC stated that DOE should 

require testing at low, medium and high room light levels, all at least 100 lux or brighter, to 

better represent actual viewing conditions. (NRDC, No. 5 at p. 5) Further, NRDC asserted that 

the test should require the lab technician to report the power levels, at different luminance levels, 

and leave it to the policy maker to determine the weight at each level. The test procedure should 

also require testing with ABC off. (NRDC, No. 5 at p. 5) CEA advised against changing the 

ENERGY STAR specification, as testing at additional luminance levels will not create a more 

repeatable and representative test method without further testing. (CEA, No. 13 at p. 6) CEA 

recommends the use of ENERGY STAR's ABC test, but changing "300 lux or greater" to "300 

lux" with a reasonable tolerance limit. (CEA, No. 13 at p. 6) Additionally, Panasonic noted that 

if absolute luminance measurements are required at various levels other than 0 lux and greater 

than 300 lux, it will be difficult to develop a test method that ensures accurate and repeatable 

results across labs. (Panasonic, No. 6 at pp.5-6) Sony believes that accurately capturing light 

conditions and energy savings associated with TVs equipped with ABC is difficult. Illuminance 

meters must be placed in the exact same position and orientation of the light sensor of the TV, in 

order to properly create the desired illuminance which varies from home to home and from test 

lab to test lab. Sony stated that the lighting conditions are outside of the scope of the test 

procedure. (Sony, No. 8 at p. 3)
85

Alternatively, SHARP recommended that, at a minimum, the low light condition be 

increased somewhat above 0 lux, but to determine an appropriate value, or if additional levels are 

required, more data collection and study is required. (SHARP, No. 14 at p. 5) SHARP also 

supported the high illuminance condition being at precisely 300 lux, allowing for some 

reasonable tolerance in the measurement condition. (SHARP, No. 14 at p. 5)

To determine the appropriate illuminance levels required during on mode testing for 

those TVs with ABC-enabled by default, DOE analyzed a Japanese study28 undertaken by Sony, 

Seikei University, Sharp, and Panasonic pertaining to room illuminance and ABC. In addition, 

DOE conducted its own preliminary room illuminance field test29. In 2011, the Japanese study of 

77 Japanese homes found that the most common room illuminance range of either day or night 

measurements was 50 to 75 lux, and room illuminance was 100 lux or less in more than 50

percent of the measurements.

In June 2011, DOE conducted its own preliminary field tests of room lighting levels 

during TV viewing events30. Room lighting levels and TV power consumption were logged 

continuously over a one-to-two week period in nine homes. From this data, light levels were 

correlated to times when the TV was actually being watched. Across the nine homes, the TV was 

watched for 10 minutes or more 95 times in the period under consideration. DOE has collated the 

logged illuminance levels for each of those sessions, defined as “TV viewing session room

illuminance” measurements, and found that they ranged in duration from 10 minutes to over five

hours. Thirty-one, or about one-third, of the TV viewing sessions occurred during the day 

(defined as 6 am to 6 pm), and 64, or about two-thirds, occurred at night (6 pm to 6 am). For 

daytime measurements, the range was 0 to 499 lux, with a mean of 116 lux and a median of 81 

lux. For nighttime measurements, the range was 0 to 106 lux, with a mean of 19 lux and a 

median of 12 lux. Across all room illuminance measurements, the mean was 51 lux and the 

median was 17 lux. More than 90 percent of measurements had a room illuminance level 

between 1 and 200 lux, and more than 70 percent of the measurements had a room illuminance 

level between 5 and 100 lux.

In addition to the Japanese study and its own preliminary study, DOE is also aware that 

CLASP recently conducted a study which assessed how TV energy consumption is affected by 

illuminance levels31. The CLASP study found that there is no consistency in the way in which 

manufacturers implement ABC (e.g. automatically adjusting TV luminance according to the 

ambient light levels). The CLASP study suggested that appropriate room illuminance levels at 

which to measure ABC are: 10, 50, 100, and 300 lux32 to properly characterize how ABC 

performs.

Given DOE’s preliminary results that more than 70 percent of measurements fell between 

a room illuminance level of 5 and 100 lux, and CLASP’s recommended room illuminance levels,

DOE is proposing to require testing at 10, 50, 100, and 300 lux illuminance levels in this NOPR.

DOE is proposing this testing in section 5.5.1 of appendix H to subpart B of 10 CFR part 430. 

These proposed illuminance levels will help to characterize how TV energy consumption is 

altered by ABC, which is affected by changes in room lighting. The CLASP study included 

testing on forty TVs and investigated the energy consumption of TVs using ABC at various 

illuminance levels. DOE’s own laboratory testing revealed that televisions implement ABC 

differently, with screen luminance often following a complex function of room illuminance. 

Some televisions exhibit an increase to nearly full screen luminance slightly above 0 lux, while 

others exhibit an “S-shaped” response to room illuminance, with maximum change occurring 

between approximately 50 and 100-150 lux. Having at least three (and ideally four) measurement 

points at increasing room illuminance levels can begin to capture the shapes of either of these 

behaviors that become clearly evident with larger numbers of measurements.

DOE is not proposing testing at 0 lux, because it believes that ambient lighting levels this 

low are very difficult to achieve in practice in homes or laboratories when the television is 

operating. DOE is only proposing one point above 100 lux, based on the limited evidence 

available from the Japanese study and its own study (both referenced above), DOE assumes that 

viewing at illuminance levels higher than 100 lux will be limited. The studies measured room 

illuminance at different points – the Japanese study from the top of the television and facing the 

viewer, the DOE study from the bottom bezel of the television and facing the viewer - however, 

with the limited data collected, static measurements of light levels at these locations in the DOE 

study suggest that the difference in the recorded values is relatively small (12 percent lower 

when measured at the top of the television). DOE is also proposing to measure these 4 illuminace 

values with the IEC 62087-2011 main menu displayed on the TV. This screen is a static image 

that is seen directly before the Dynamic Broadcast video clip and is a predominantly black 
88

screen. This allows the TV to stay on so it doesn’t need to be warmed up again and increases 

repeatability.

DOE is proposing testing at multiple levels to reflect how ABC could change display 

luminance in relation to changes in room illuminance. Although DOE believes that testing at 

four illuminance levels is the most appropriate for this test procedure, it is also considering 

measuring at alternative illuminance levels to reduce test burden. DOE welcomes any comment 

on potentially testing less than four room illuminance levels, including which levels would be 

recommended and the rationale for such levels.

DOE believes that it is difficult to measure exact ambient light values with illuminance 

meters having high accuracy (high resolution). As such, DOE is proposing specified tolerance 

values for each ambient light level. All measurements made shall be within the specified 

tolerance levels. The proposed tolerance levels for room illuminance measurements are based on 

the observation that power consumed by ABC-enabled products varies greatly with changes in 

ambient lighting conditions less than 100 lux. Based on this observation, DOE would require that 

measurements at lower lighting levels be made as accurate as possible and, as such, proposes low 

tolerance levels at 10 lux (± 1 lux ) and 50 lux (± 2 lux ). DOE observed low variance in power 

consumed by TVs at higher ambient light levels and hence proposes greater tolerance levels at 

100 lux (± 5 lux) and 300 lux (± 9 lux). These tolerance requirements have been incorporated in 

section 5.5.1 of appendix H to subpart B of 10 CFR part 430 DOE seeks comments from 

interested parties on setting tolerance levels at each room illuminance point. (See Issue 8 in 

section V.E ”Issues On Which DOE Seeks Comment”)
89

DOE is currently not proposing to weigh power consumption at each of the illuminance 

levels. DOE is, however, considering a weighted average to calculate the overall power 

consumption recorded when testing at the four illumination levels by assigning equal weights to 

each of the values. The weighting would reflect the amount of time that the average TV spends 

in that particular illuminance level. Providing weighting to different illuminance levels reflects 

the fact that TVs are watched in rooms with different lighting levels and at different times of the 

day. If DOE had additional data on the proportion of time TVs spend within different 

illuminance ranges, DOE might consider assigning different weightings to the power 

consumptions recorded at each illuminance level. DOE welcomes comments from interested 

parties on the methods under consideration. (See Issue 8 in section V.E ”Issues On Which DOE 

Seeks Comment”).

ii. Method for Creating Illuminance Conditions

Once the respective illuminance levels have been selected, DOE must specify how to 

create the room illuminance in the test procedure to be both repeatable and representative. This 

involves the orientation of the illuminance measurement meter, the light source type and the 

location for measurement.

In today’s NOPR, DOE is proposing to measure the room illuminance at the location of 

the ABC sensor on the TV with the light entering directly into the sensor. This method is 

currently being employed by ENERGY STAR v. 5.3 as well as IEC 62087-2011, and was 

generally supported by interested parties. However, DOE is also considering an alternative 

method. The alternative method requires that the room illuminance be created using a diffused 
90

light source, and be measured either at the center of the screen or the location of the ABC sensor. 

In response to the 2010 RFI, DOE received comments on the appropriate method for creating 

illuminance levels. 

DOE received general comments requesting a test procedure that clearly outlines where 

to create and measure room illuminance with respect to the TV. NRDC encourages DOE to 

establish a more specific test method on how to measure the light that is entering the ABC sensor 

and/or the TV screen, but NRDC did not specify an appropriate alternative. (NRDC, No. 5 at p. 

5) NRDC stated that the test procedure should provide detail on the orientation of the 

illuminance meter, the type of light source, and the location for measurement. (NRDC, No. 5 at 

p. 6) PG&E and California IOUs recommended that DOE specify guidance on illuminance meter 

orientation, source light and the direction of the source light to ensure consistent testing across 

products. (PG&E, No.12 at p. 3; California IOUs, No. 9 at p. 3)

Commenters expressed desire for measuring the room illuminance at the location of the 

light presence sensor with the light directly entering the sensor. PG&E and the California IOUs 

recommend that measurement of room illuminance be taken at the location of the TV light 

presence sensor. (PG&E, No.12 at p. 3; California IOUs, No. 9 at p. 3) Sony believed that to 

accurately capture light conditions, the illuminance meter should be placed at the sensor. (Sony, 

No. 8 at p. 3) Panasonic recommended that ABC be measured with the light entering directly 

into the TV's ambient light sensor as specified by IEC 62087-2008, ENERGY STAR v. 4.1, and

CEA 2037. (Panasonic, No. 6 at p. 6) CEA similarly commented that the illuminance 

measurement should be taken at the sensor and the illuminance meter should be in the same 

horizontal orientation as the light sensor to ensure repeatability across measurements. (CEA, No. 
91

13 at p. 6) Finally, Panasonic commented that the illuminance should be measured immediately 

adjacent and in the same plane as the TV's ambient light sensor opening. They believe that 

measuring light at the center of the screen will not provide meaningful and repeatable results. 

(Panasonic, No. 6 at p. 6) SHARP commented that manufacturers do not gain any advantage by 

putting the ABC sensor in an obscure or hidden position, and thus the illuminance measurement 

location should be at the sensor. (SHARP, No. 14 at p. 6) SHARP also believed that no problem 

exists with respect to measurement location and lighting, and anything other than the IEC 62087-

2008 method adds complexity, uncertainty and cost to the measurement. (SHARP, No. 14 at p. 

6)

DOE evaluated a second option for furnishing ambient light to the automatic brightness 

control sensors in a laboratory setup. This second option utilizes a diffuse light source. Such a 

source would be located further away from the TV than a direct source, and its light would reach 

the TV through a combination of direct and indirect (e.g., reflections from the ceiling, walls, and 

floor) pathways. Although a diffuse light source better represents actual in-home lighting 

conditions, DOE determined that such an approach depends on too many variables that are 

difficult to control and which introduce uncertainties into the test procedure relative to the direct 

approach. The diffuse light source would need to be much brighter in order to yield the target lux 

values at the television. The light would be arriving at the television from many different angles 

and would be incident on the television screen as well as its ABC sensor. This increases the 

likelihood that the technician’s position in the room during the test would influence the measured 

result, and makes it difficult to employ a non-contact luminance meter for television screen 

brightness measurements. Finally, differences in test room size, configuration, surface 

reflectivity, and light source type would also make it very difficult to replicate identical test 
92

conditions in multiple laboratories. For the above reasons, DOE proposes to employ only a 

direct light source for all ABC testing.

In addition to specifying to lighting position and sensor measurement location, DOE also 

believes that it is necessary to specify the lighting type. Of artificial lighting sources, 

incandescent light most closely follows the spectral distribution of natural light. Compact 

fluorescent lights (CFL) and LED tend to be discontinuous in the spectral density curves which 

may impact the ABC sensors ability to perceive light. Incandescent lights have a color rendering 

index (CRI) of about 100 while CFL and LED have a CRI ranging from 75-85 (natural light has 

a CRI of 100, a metric used for how light makes the perceived color of an object appear). DOE is 

proposing that the room illuminance be created only by using 100 watt halogen incandescent 

light bulbs, although the number of bulbs need is dependent on the size of the room and the 

distance from the ABC sensor. 

While DOE feels that specifying a halogen incandescent is sufficient for creating a 

repeatable lighting condition, DOE requests comments on incorporating a color temperature 

range in addition to lighting type. Consumers have a wide variety of lighting options to choose 

from ranging from “warm” (2800 – 3000 K) to “cool” (3600 – 5500 K) color temperatures and it 

is still unknown how these characteristics may be perceived by ABC sensors. DOE also requests 

comments on a warm-up time for the lighting source. Incandescent lights do not typically have 

the same warm-up characteristics as other lights like CFL that require time before reaching their 

optimal brightness.
93

In today’s NOPR, DOE is proposing to measure the room illuminance at the location of 

the ABC sensor on the TV with a halogen incandescent light source entering directly into the 

sensor in section 5.5.2 of appendix H to subpart B of 10 CFR part 430. Although neither 

ENERGY STAR v. 5.3 or IEC 62087-2011 specifies the particular location of the light source, 

DOE believes that through specifying the location, it will have a more thorough and complete 

test procedure that is representative of actual use. Although DOE is proposing to measure using 

only one light source, DOE is also interested in receiving feedback on measuring using multiple

light sources. (See Issue 9 in section V.E ”Issues On Which DOE Seeks Comment”).

c. Television Sets Shipped without Automatic Brightness Control Enabled

For TVs shipped without ABC enabled, DOE is proposing to incorporate testing 

consistent to that in the ENERGY STAR v. 5.3, which references Section 11: Measuring 

Conditions for Television Sets in On (average) Mode of IEC 62087, Ed 2.0. DOE believes that 

this is a respected method that is widely accepted in industry and reasonably measures the 

average on mode power consumption of the TV in section 5.4.1 of appendix H to subpart B of 10 

CFR part 430. In this test procedure, the on mode power consumption is obtained by playing the 

IEC 62087-2011 dynamic-broadcast video signal (which was created to mimic typical TV 

content) in “as shipped” condition which is the mode in which DOE assumes that most TVs stay 

according to feedback from Sony. As noted above, Sony commented that their call center data 

indicates that more than 95 percent of returned sets remain in the home picture setting when 

received. (Sony, No. 8 at p. 2) DOE did not receive any comments pertaining to on mode power 

testing for TVs shipped without ABC enabled. 
94

d. Three Dimensional Display Testing

In the 2010 RFI, DOE requested comment on incorporating a test method for testing TVs 

capable of displaying 3D images in 3D mode. 75 FR 54048, 54051. Interested parties 

commented on the inclusion of this testing into the DOE test procedure.

All agreed that 3D was likely to become increasingly prevalent. Interested parties, 

however, had mixed views as to the importance of DOE incorporating 3D testing in this version 

of its test procedure. Some did not seem to consider it a priority, some considered it premature, 

stating that the market share is currently small but rapidly increasing and the technology is still 

developing, and others felt it should clearly be included. Sony offered its support to DOE’s 

studies into 3D technology. They believe that the amount of time consumers spend watching 3D 

content is currently relatively small compared to 2D content but increasing. Sony believes that 

sufficient time should be allowed for the IEC to create a 3D version of its 2D dynamic broadcastcontent video signal. (Sony, No. 8 at p. 3) Mitsubishi commented that a test procedure for 3D 

should be included in DOE’s test procedure but it need not involve a 3D disc, 2D content could 

be converted to 3D in real time. (Mitsubishi, No. 7 at p. 6) NRDC commented that TVs having 

the "3D boost" feature could result in a significant increase in TV power to display 3D content. 

(NRDC, No. 5 at p. 6) Panasonic asserts that TVs display 3D images in a similar manner as 2D 

images. Thus, they believe that a TV that is efficient in 2D mode will also be efficient in 3D 

mode, when compared to other TVs operating in 3D mode. Once IEC has developed a 3D clip, 

or even before, Panasonic believes that it should be referenced by DOE. (Panasonic, No. 6 at p. 

7) CEA believes that DOE should support standards development organizations investigating 3D 

technologies but due to the lack of a standardized method and current small volumes on the

market, 3D technology should not be included in DOE's current test procedure. CEA 
95

acknowledged that it may be appropriate to modify the DOE test procedure in the future to 

include 3D testing. (CEA, No. 13 at pp. 7 – 8) P.R. China suggested that it is too early to 

consider 3D technology in the DOE test procedure. (P.R. China, No. 16 at p. 5) SHARP believes 

that it is premature to set power standards for TV in 3D modes stating that there are three things 

that are needed: standardized language for testing, a standardized test signal, and accurate 

weightings based on actual viewing habits. SHARP recommended that the IEC develop a 3D 

dynamic broadcast-content video signal, but such a result is unlikely to be available before late 

2012. (SHARP, No. 14 at p. 7) DOE should revisit 3D power measurements when a 3D dynamic 

broadcast-content video signal becomes available – probably no earlier than 2013. (SHARP, No. 

14 at p. 7) PG&E, California IOUs, and Mitsubishi supported DOE in currently including 3D 

testing in its proposed test procedure. PG&E and California IOUs commented that 3D TVs are 

expected to significantly increase in market share, and drop in price. Therefore they urged DOE 

to develop a test procedure that applies to 3D TVs on the market. (California IOUs, No. 9 at p. 3; 

PG&E, No. 12 at p. 3) Although Mitsubishi recognized the difficulties of creating a test 

procedure for testing 3D, they believed that power consumption in 3D operating mode(s) should 

have a single, recognized test procedure, and that power consumption in 3D operating mode(s) 

should be measured. (Mitsubishi, No. 7 at p. 6) 

DOE recognizes that 3D content is becoming increasingly popular and that 3D TVs are 

becoming more affordable. PG&E and California IOUs cited a study that showed that 3D TVs 

are projected to increase from 4.2 million units in 2010 to 78 million units by 2015, rising at a 

compound annual growth rate of 80 percent, and that the global average selling price for 3D TVs 
96

in 2015 will drop by more than half the price in 201033. (California IOUs, No. 9 at p. 3; PG&E, 

No. 12 at p. 3) Industry has more recently indicated that over the next couple of years 3D will 

become a common feature on many TVs, almost available as standard on larger screen sizes and 

with higher end models (Society for Information Display conference, 2011). Moreover, 3D 

content is becoming increasingly prevalent with emerging native 3D material (movies, sports 

content etc. shot in 3D), and Blu-ray players and TVs on the market with the ability to convert 

content from 2D to 3D. DOE understands the need for a standardized method for measuring the 

power consumption of TVs in 3D mode. DOE’s research thus far indicates that for most 

mainstream technologies’ 3D mode consumes a significant additional power premium. However,

DOE understands that 3D is a developing technology and will most likely take time to mature. 

In today’s NOPR, DOE is not proposing to include a test procedure to measure 3D 

energy consumption for the reasons that: (a) 3D technology has not yet stabilized, and (b) a 

uniform method for 3D mode energy measurement has not yet been created. However, DOE is 

considering two potential alternatives for future inclusion in its test procedure. The two

alternatives involve either creating a 3D dynamic broadcast-content video signal similar to that 

of the IEC 62087-2011 dynamic broadcast-content video signal, or employing a device that can 

uniformly convert the 2D dynamic broadcast-content video signal to 3D and output 3D content 

in real time. The two potential test methods under consideration are outlined below.

For the first approach that DOE is considering, DOE would create a 3D test disc capable 

of being played in a Blu-ray player. DOE has been working closely with the IEC. IEC has agreed 

 

33 Global 3-D TV Shipments Set to Soar to 78 Million Units in 2015. Riddhi Patel. iSuppli Press Release. March 1, 

2010. 
97

in principle to provide DOE with all the rights which it is able to provide DOE to modify the 2D 

test clip and distribute modified versions of the test clip. If DOE creates a modified 3D version 

of the IEC test clip for any purpose, it has agreed to provide a copy to IEC which IEC could then 

use in its development of an IEC 3D test clip34.

It is the intent of DOE that the disc will be capable of playing Blu-ray format 3D, a 

HDMI 1.4 interface at 1080 horizontal lines of vertical resolution and at least 1440 vertical lines 

of horizontal resolution. When playing the disc, 3D capable TVs will recognize that the disc 

contains 3D content, and will switch into 3D mode. The average APL of the 3D disc would be 34 

percent thus simulating normal viewing content even while the TV is in 3D mode. At this time, 

DOE believes that this approach is the best approach for developing a 3D test procedure and is 

interested in working with the IEC and other interested parties in its development.

DOE is also considering a second approach, which employs a device that can convert the 

2D test clip to 3D and output 3D content in real time. Under this approach, DOE would try to 

develop a performance specification for Blu-ray devices that have this capability to ensure that 

the test results are consistent across labs if using different 2D to 3D convertors. DOE has tested 

some of these devices, and cannot conclude at this time what the performance specification 

should be for these devices. However, DOE welcomes comments on this aspect of the test 

procedure under consideration.

 

34 IEC and necessary copyright holders have agreed in principle to allow DOE to modify the test clip and return it to 

IEC. IEC is able to assign rights over the material in the test clip with the possible exception of certain portions of 

the test clip owned by one copyright holder. Currently, DOE is in discussions with that copyright holder.
98

As mentioned, DOE has performed 3D testing using two Blu-ray players available for 

sale in the U.S. from different manufacturers, both of which are able to convert 2D images to 3D 

in real time. DOE measured the average power consumption over a specified amount of time and 

then played a 2D disc of the same footage on the 2D to 3D converter. DOE found very little 

difference between TV power measured using 3D source material and TV power measured using 

2D source material converted to 3D using the Blu-ray players. To make the comparison, DOE 

used market available Blu-ray videos with both a 3D and a 2D version and measured the energy 

consumption over the same ten minute section of the film using both methods for generating 3D 

material. The comparison was made on five 3D capable televisions spanning LED LCD, plasma, 

and DLP technologies.

DOE believes that, generally, the limited test results of the convertor are comparable to 

those of playing 3D content. However, there were issues with this approach. DOE is concerned 

that the variability found between playing the test clip in the converter, versus playing a 3D test 

clip, can be a function of the test clip, converter and TV used in the test and is not certain how to 

develop an adequate performance specification for the converter alone. DOE also found through 

testing that not all convertors worked with all TV brands. Further, DOE determined that, in some 

cases, the convertors put the TV into a mode that consumed less energy when playing 2D content 

converted to 3D than when playing the same content in 2D.

DOE requests comment on these two options for generating the video signal for 3D TVs,

along with any other considerations for testing 3D TVs. (See Issue 10 in section V.E ”Issues On 

Which DOE Seeks Comment”).
99

5. Standby and Off Modes

As mentioned above, EISA 2007 requires DOE to include consideration of standby mode 

and off mode energy consumption in future amendments to both its test procedure and energy 

conservation standard. In order to adhere to EISA 2007, DOE is proposing to include the standby

mode requirements according to IEC 62087-2011 and the off mode requirements according to 

IEC 62301-2011. When developing a proposed standby and off mode test procedure, DOE 

assessed both IEC 62301-2005 Household Electrical Appliances – Measurement of Standby 

Power and IEC 62087-2011. ENERGY STAR v. 5.3 references IEC 62087-2011. In today’s 

NOPR, DOE is proposing to incorporate standby tests for standby-passive in section 5.6.1 

(standby-passive mode test) of appendix H to subpart B of 10 CFR part 430 and standby-active, 

high in section 5.6.2 (standby-active, high mode test) of appendix H to subpart B of 10 CFR part 

430 as well as an off mode test in section 5.7 (off mode) of appendix H to subpart B of 10 CFR 

part 430. Although DOE is not currently proposing to include a standby test for standby-active, 

low, DOE is considering this requirement for the future.

In the 2010 RFI, DOE requested comments dealing with standby and off mode. 

Specifically DOE focused on additional functions, internet connectivity and power saving 

technologies, since they can possibly alter the energy consumed by the TV. 75 FR 54048, 54051.

a. Additional Functions

As mentioned above, additional functions have the potential to increase energy 

consumption while the TV is in standby and off mode. Additional functions are defined as any 

function that is not required for the basic operation of the device. Although DOE did not 
100

specifically request comments pertaining to additional functions in the 2010 RFI, both NRDC 

and SHARP provided comments on assessing the power use associated with additional functions.

NRDC asked that DOE provide guidance in its test procedure for additional functions and 

that DOE revise the standby section of IEC 62087-2008, which is the same as IEC 62087-2011.

NRDC believes that the test procedure must address whether the TVs additional functions should 

be left as is, turned on, or turned off/disabled prior to testing. (NRDC, No. 5 at p. 2)

Although NRDC requested guidance, they were generally opposed to testing with 

additional functions switched on unless initially enabled by default. NRDC believes that built-in 

DVD and Blu-ray players should be tested without a disc inserted, and play should not be 

selected. However, they believe that the DVD and Blu-ray players should not be allowed to be 

turned off or physically removed prior to testing. (NRDC, No. 5 at p. 2) NRDC also commented 

that the TV should be tested without the cable card inserted, but DOE should potentially include 

a supplement to its test procedure that allows guidance on how to report for features such as 

cable cards. (NRDC, No. 5 at p. 3) Additionally, DOE should gather data and evaluate methods, 

including the Australian method, which includes measuring standby-active and standby-passive

once the TV has been tuned to an Australian broadcast channel. (NRDC, No. 5 at p. 7)

SHARP was also opposed to enabling additional functions when conducting energy 

measurements. SHARP commented that IEC 62087-2008 requires that additional functions be 

turned off to provide for equivalent TV model comparison. (SHARP, No. 14 at p. 8) SHARP 

recommends that DOE follow precedence and measure the basic TV functions without 
101

intervention in the areas of nascent technologies, services and innovations. (SHARP, No. 14 at p. 

9)

In this NOPR, DOE is proposing testing the TV as shipped, without manually enabling 

any additional functions. This method is consistent with the comments made by both SHARP

and NRDC. Although enabling additional functions while testing in standby and off mode would

encourage manufacturers to lower energy consumption for those functions, it would make it

difficult to compare TVs with different functions. Also, DOE is not aware of any usage data that 

illustrates how consumers use TVs with additional functions and DOE believes that proposing 

testing with additional functions would require an understanding of such usage.

b. Power Saving Technologies

The number of TVs that are being sold with various power saving technologies is 

continuing to increase, and therefore DOE investigated the how these technologies affect energy 

consumption. These technologies include, but are not limited to, auto-shut-off, presence sensor, 

DPMS, and HDMI-CEC.

Panasonic, Sony, NRDC, and SHARP believe that TVs with power saving technologies 

should not be given an energy credit in the current rulemaking because many are still being 

developed. Panasonic believes that it would be difficult to determine the amount of power saved 

and to obtain data by various power saving technologies and complex measurement procedures 

will not be useful. (Panasonic, No. 6 at p. 7) Sony stated that it is impossible to know the actual 

savings of energy saving functions, so additional studies are needed prior to DOE adopting them 

in its test procedure. (Sony, No. 8 at p. 4) LG stated that the ENERGY STAR and IEC 62087-
102

2008 test procedure, which only account for ABC, adequately evaluate power saving functions 

available today. (LG, No. 3 at p. 2) CEA also stated that not every possible energy using feature 

needs to be covered, especially if it is too difficult, impractical, costly or speculative. (CEA, No. 

13 at p. 2) More specifically, NRDC and Panasonic do not support giving credit for presence 

sensors; a power saving technology that turns the TV off if it senses that no consumers are 

viewing it. They believe that the technology will likely be disabled by the consumer; assuming 

the TV is shipped with presence sensors enabled. (NRDC, No. 5 at p. 7; Panasonic, No. 6 at p. 

8). 

SHARP also noted that many power saving technologies are proprietary and should 

therefore be avoided. Specifically, DPMS has intellectual property implications. (SHARP, No. 

14 at p. 9) SHARP believes that HDMI-CEC can provide some mechanisms for power saving. 

They supported their comment by stating that the application layer is not well enough defined for 

consistent cross-company interoperability, and many HDMI-CEC implementations are currently 

proprietary. (SHARP, No. 14 at p. 9)

Many interested parties supported DOE research into power saving technologies. NRDC 

urged DOE to revisit power savings features, and whether credits should be provided for power 

saving features. (NRDC, No. 5 at p. 7) CEA also encouraged DOE to continue to study and 

investigate energy saving features but be cautious as to not promote technology that is restrictive 

and costly. (CEA, No. 13 at p. 8) CERC believes that the standard should be allowed to evolve 

with new technologies. CERC commented that technologies still in early development, including 

automatic shut-off and ABC, should be allowed to be developed more fully before a standard and 

test procedure are imposed on their operation, allowing manufacturers more incentive to 
103

innovate. (CERC, No. 10 at pp. 2-3) PG&E and the California IOUs urged DOE to account for 

new technologies in the test procedure to the greatest extent possible. (PG&E, No. 12 at p. 4; 

California IOUs, No. 9 at p. 4) 

Finally, some manufacturers commented on specific power saving technologies available

in products today. Sony commented that its TVs contain intelligent presence sensors with face 

and motion detectors, light sensors, power savings (regardless of picture mode), idle TV standby, 

auto shut-off and the energy savings switch (completely off). (Sony, No. 8 at p. 4) LG 

commented that their TVs have features that place the TV into standby mode if no signal is 

present for 15 minutes. (LG, No. 3 at p. 2) SHARP commented that the auto-standby feature that 

is available in some manufacturers’ products can potentially save energy, but also may annoy 

consumers. (SHARP, No. 14 at p. 9) SHARP also believes that California’s requirement that the 

power button put the TV into passive standby, can have negative consequences, such as 

terminating a nearly complete program guide download. (SHARP, No. 14 at p. 9)

Given the interested party feedback, DOE is not proposing to test new power saving 

technologies because DOE believes more investigation is needed to be able to better understand 

any potential benefits from these technologies. Although DOE will continue to investigate the 

new technologies, DOE believes that the market is currently at too early a stage of development. 

In order to continue to investigate these new technologies, DOE welcomes interest parties submit 

information pertaining to all power saving technologies, which would help DOE in its 

investigation present on TVs.
104

c. Standby Modes

i. Standby-Passive Mode

As stated in section 5 above, DOE is proposing a test procedure for standby-passive 

mode in section 5.6.1 (standby-passive mode test) of appendix H to subpart B of 10 CFR part 

430. IEC 62087-2011 defines standby-passive mode as the mode in which the appliance is

connected to a power source, produces neither sound nor picture but can be switched into another

mode with the remote control unit or an internal signal as referenced in III.C.3.a of this NOPR. 

Testing in this mode would require putting the TV into standby-passive mode as defined in 

section 2.12 (standby-passive mode) of appendix H in subpart B of 10 CFR part 430, and 

measuring the power consumed according to section 4.3.1 of IEC 62301-2011. Standby-passive 

mode would include modes such as when the TV is connected to the internet but not actively 

receiving a signal.

ii. Standby-Active, Low Mode

The number of TVs that are being sold with the capability of accessing the internet 

(either wirelessly or via Ethernet) is continuing to increase; PG&E and California IOUs stated 

that by 2014, internet-enabled TVs are estimated to account for 54 percent of the total global TV 

market. They supported their statement by commenting that in 2010, shipments of these TVs 

rose 125 percent globally from 2009. (PG&E, No. 12 at p. 4; California IOUs, No. 9 at p. 4) In 

the 2010 RFI, DOE requested comments on testing TVs with internet connectivity. 75 FR 54048, 

54051.

Some interested parties commented in favor of TVs being connected to the internet when 

measuring standby and off mode energy consumption. NRDC suggested that the TV should be 
105

connected to the internet, then turned off normally, and the energy consumption associated with 

the TV being connected to the internet should be measured and reported as part of standby power 

use. (NRDC, No. 5 at p. 2) PG&E and the California IOUs also stated that DOE should 

incorporate internet connectivity and power usage associated with this feature in the test 

procedure. They suggested that DOE do this by including a network mode, consistent with what 

will be included in IEC 62301 Edition 2.0. (PG&E, No. 12 at p. 4; California IOUs, No. 9 at p. 4)

Other interested parties commented that internet connectivity energy consumption should 

not be included in the test procedure. Interested parties commented against including a general 

internet measurement as well as enabling internet when conducting the standby test. Interested 

parties reasoned that internet connectivity has not been researched thoroughly, and is still in the 

early development stages. Sony commented that their limited data suggests that the power 

consumption of TVs equipped with Ethernet ports is equivalent to the power consumption in the 

home mode while streaming contracted network connects from the various service providers. 

(Sony, No. 8 at p. 3) Sony also stated that because power and usage of internet capable TVs is 

unknown, additional study is needed prior to incorporating it into the test procedure. (Sony, No. 

8 at p. 3) CEA similarly stated that internet connectivity is still in an early phase of development 

and should therefore not be included in the test procedure without further research. (CEA, No. 13

at p. 8) Panasonic recommends using the same on mode power measurement with the IEC 

62087-2008 dynamic-broadcast video signal, regardless of the TV’s internet capabilities. 

(Panasonic, No. 6 at p. 8) Panasonic believes that the power consumed from an internet 

connection is minimal and complex, and will be difficult to reproduce. (Panasonic, No. 6 at p. 8)

SHARP further commented that consumers all use the internet differently, so setting a test 

procedure to mirror actual internet use would be a daunting task with minimal value. (SHARP, 
106

No. 14 at p. 8) SHARP believes that much more study is required before DOE can characterize 

the power consumed from TVs based on active internet use. (SHARP, No. 14 at p. 8) SHARP

believes that due to competitive pricing, TVs have limited storage capacity, and therefore 

internet communications are limited or non-existent when the TV is in sleep mode, making 

testing it not relevant. (SHARP, No. 14 at p. 8)

Other interested parties commented on specific details pertaining to internet connectivity 

energy consumption. NRDC believes that the test procedure should have language to ensure that 

no content is being downloaded from the internet while the measurement is being made. (NRDC, 

No. 5 at pp. 2 -- 3) LG commented that “currently the HDMI input is available to the IEC 

Standard 62087 internet source; however it is impossible to implement it through the current 

environment LAN Port.” (LG, No. 3 at p. 2) DOE notes that while IEC 62087-2011 provides a 

video signal of different websites to represent internet energy consumption, there is currently no 

standard method for measuring actual internet usage when connected to the internet via a LAN 

Port.

Given the comments received in the 2010 RFI, DOE researched the energy consumption 

associated with internet, HDMI, and cable connectivity. DOE completed standby and off mode 

energy testing while the TV was connected to the internet (both wirelessly and via Ethernet), 

while connected to a cable signal, while connected to a peripheral device through a HDMI cable 

and while not connected to input or output sources except for power. DOE found very little 
107

evidence of increased energy consumption associated with additional connections while the TV 

was in standby and off mode35.

In today’s NOPR, DOE is proposing to test standby and off mode energy consumption

without having the TV connected to the internet in sections 5.6 (standby mode tests) and 5.7 (off 

mode test) of appendix H to subpart B of 10 CFR part 430. As mentioned above, DOE also 

conducted testing when the TV was connected to both a cable signal and an HDMI input. DOE 

did not measure a significant power increase when the TV was connected to the internet, cable or 

an HDMI input while in standby mode or off mode36 DOE believes that conducting additional 

standby testing while the TV is connected to an internet, cable or HDMI input is unduly 

burdensome due to the lack of significant results indicating increased energy consumption from 

DOE’s testing. Therefore, DOE is not proposing to require that the TV be connected to a cable 

input, HDMI input or to the internet when testing standby and off mode energy consumption.

However, DOE welcomes comments by interested parties on the energy consumption associated 

with internet connectivity in standby mode should be included. (See Issue 11 in section V.E

”Issues On Which DOE Seeks Comment”).

iii. Standby-Active, High Mode

IEC defines standby-active, high as the mode when the appliance is connected to a power 

source, produces neither sound nor picture but can be switched into another mode with the 

remote control unit or an internal signal and can additionally be switched into another mode with 

 

35 The data indicating a lack of increased power consumption associated with connecting the TV to the internet, 

cable or an HDMI input can be found on the DOE website: Appliance and Commercial Equipment Standards: 

Television Sets. U.S. Department of Energy. August 2, 2011. 

<http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html>

an external signal and is exchanging/receiving data with/from an external source. DOE believes 

that the TV is in standby-active, high mode when the TV is actively exchanging/receiving data 

(likely from the internet) as well as while in DAM mode. In the 2010 RFI, DOE requested

feedback as to the possibility of including a DAM test. 75 FR 54048, 54051.

iv. Download Acquisition Mode

ENERGY STAR v. 5.3 defines DAM as the mode where the product is connected to a 

mains power source, is not producing a sound or a picture, and is actively downloading data, to 

include but not limited to, channel listing information according to a defined schedule for use by 

the electronic programming guide, TV setup data, channel map updates, TV firmware updates, 

monitoring for emergency messaging/communications and/or otherwise communicating through 

a network protocol. DOE believes it is important to include DAM testing because the tested TVs 

had heightened energy consumption while in this mode.

Several interested parties commented that DAM should be tested. PG&E and the 

California IOUs indicated that there has been at least one reported instance of a TV consuming a 

significantly greater amount of power and spending a majority of time in DAM when the TV 

should have been in standby mode. Therefore, they urged DOE to account for DAM in its test 

procedure. (PG&E, No.12 at p. 5; California IOUs, No. 9 at p. 5) They requested that the test 

programming content, used for testing in DAM, should be publically available and able to be 

utilized by non-proprietary technology. (PG&E, No.12 at p. 4; California IOUs, No. 9 at p. 4)
109

Many interested parties specifically suggested that DOE implement the “CEA Test 

Procedure for Download Acquisition Mode Testing37” (CEA test procedure for DAM testing). 

Specifically, Sony, LG, Panasonic and CEA recommended that DOE adopt this test procedure. 

(Sony, No. 8 at p. 3; LG, No. 3 at p. 2; Panasonic, No. 6 at p. 8; CEA, No. 13 at p. 8) Panasonic 

and Sony supported their recommendations by noting that ENERGY STAR v. 4.1 references the 

CEA test procedure for DAM testing. (Panasonic, No. 6 at p. 8; CEA, No. 13 at p. 8)

Alternatively, SHARP commented that although the CEA test procedure for DAM testing 

is a good test procedure, it should not be incorporated into DOE’s test procedure. SHARP

supports the flexibility of the CEA test procedure for DAM testing, but is concerned that it is not 

specific enough to be used by third parties. However, SHARP is not aware of any test procedure 

that is specific enough to fit these criteria. (SHARP, No. 14 at pp. 8, 10)

In the 2010 RFI, DOE noted that ENERGY STAR v. 4.1 tests DAM according to the

Rovi DAM test procedure. However, Rovi commented that DOE should not incorporate the Rovi 

DAM test procedure into the DOE test procedure. (Rovi, No. 4 at p. 2) Rovi explained that EPG 

software maintains a local database of programming available to the viewer, which is 

periodically downloaded during times when the TV is in the standby or off mode. Rovi noted 

that the location, previous downloads, data delivery method and communication errors are 

among the things that affected power consumption, meaning if any of these conditions are

varied, different results will be obtained. (Rovi, No. 4 at p. 1) Rovi stated that in the near-future a 

revision to ENERGY STAR v. 4.1 will replace the Rovi test procedure with a generic system 

 

37 CEA Procedure for Download Acquisition Mode DAM Testing: For TVs, September 8, 2010 

<http://www.energystar.gov/ia/partners/prod_development/revisions/downloads/television/CEA_DAM_Test_Proce

dure.pdf>
110

that depends in large measure on specific technical knowledge of the device under test (after the 

publication of the 2010 RFI, ENERGY STAR has revised their test procedure and standard to 

include the CEA test procedure for DAM testing). (Rovi, No. 4 at p. 1)

DOE notes that the CEA test procedure for DAM testing does not identify specific 

connections to be used when conducting testing. CEA only states that an appropriate signal 

source for communication should be used but does not specify what connection should be 

utilized when more than one connection could be used to communication with the DAM 

function. DOE believes that a hierarchy of network connection types is needed when more than 

one connection is capable of communicating with the DAM function to produce a more 

repeatable test procedure. DOE is proposing the following priority to ensure consistency across 

standby-active, high mode tests in section 5.6.2.1 of appendix H to subpart B of 10 CFR part 

430:

1) Wi-Fi 

2) Ethernet. If the UUT supports an Energy Efficient Ethernet, then it shall be tested 

using that connection.

3) Thunderbolt

4) USB

5) Firewire 

6) Other 

In today’s NOPR, DOE is proposing to include the DAM energy consumption testing

under its standby-active, high test method as defined in 2.3 (download acquisition mode) of 
111

appendix H to subpart B of 10 CFR part 430. The majority of interested parties including CEA, 

Sony, LG, Panasonic, PG&E, California IOUs and NRDC were all in favor of requiring a DAM 

energy consumption test. Many, including CEA, Sony, LG and Panasonic, recommended 

incorporating the CEA test procedure for DAM testing. Given the positive input from interested 

parties supporting a DAM test, and particularly the CEA test procedure for DAM testing, DOE is 

proposing to incorporate by reference the CEA Procedure for DAM Testing in section 5.6.2 

(standby-active, high mode test) of appendix H to subpart B of 10 CFR part 430. DOE is also 

aware that TVs can communicate and obtain similar information via an internet connection. 

Although DOE has developed a network connection priority list of preferred connections to 

conduct DAM testing, DOE seeks comment on using a priority list and the hierarchy that should 

be used. DOE also seeks comments from interested parties on the method for measuring standby 

mode energy consumption in all standby modes. (See Issue 12 in section V.E ”Issues On Which 

DOE Seeks Comment”).

d. Off Mode

DOE is proposing to test TVs in the off mode if applicable. DOE is defining off mode 

according to the IEC 62087-2011 definition. Off mode is the mode where the appliance is

connected to a power source, produces neither sound nor picture, and cannot be switched into 

any other mode with the remote control unit, an external, or internal signal. This mode will not 

pertain to TVs that are only able to be switched on or off with a remote, rather it will be 

applicable to TVs that have an additional switch or method of reaching this mode. In today’s 

NOPR, DOE is proposing that the power consumed in off mode be tested according to IEC 

62301-2011 section 3.5 in section 5.7 (off mode test) of appendix H to subpart B of 10 CFR part 

430. EISA 2007 requires DOE to implement an off mode energy consumption measurement. (42 
112

U.S.C. 6295(gg)(2)(A)) This particular off mode test will meet the EISA 2007 requirements and 

allow DOE to capture the energy consumption associated with the TV while it is turned off. 

DOE seeks comments from interested parties on the method for measuring off mode energy 

consumption. (See Issue 12 in section V.E ”Issues On Which DOE Seeks Comment”).

6. Energy Efficiency Metric(s) for Televisions

In today’s NOPR, DOE is considering two methods for determining the metrics of TVs in 

order to receive stakeholder comments. These methods include a luminance ratio, on mode 

energy consumption, standby mode energy consumption, and off mode energy consumption.

The first method would output four separate metrics, including a luminance ratio, on 

mode energy consumption, standby mode energy consumption, and off mode energy 

consumption. The test procedure yields a ratio of the home picture setting luminance to the retail 

picture setting luminance. This number would be expressed as a percentage (i.e., the luminance 

ratio). The test procedure would also output an on mode energy consumption according to the on 

mode test for TVs with ABC enabled by default or the on mode test for TVs without ABC 

enabled by default. For the standby mode tests, all TVs should be tested according to the 

standby-passive mode test. For TVs with DAM, the test procedure would also propose requiring 

an average energy consumption reading for standby-active, high mode. Finally, the test 

procedure would record the off mode energy consumption.

Alternatively, DOE is also considering a single output metric based on combining the on, 

standby, and off-mode energy consumption values to provide an annual energy use. The format 

of the metric, expressed as annual energy consumption (AEC, kWh/year), would be as follows:
113

AECmetric = ((Pon * Hon + Pstandby-passive * Hstandby-passive +

Poff * Hoff + DECDAM)/1000) * 365

where:

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

Hm = hours per day spent in mode m

DECDAM = daily energy consumption in DAM, if applicable (tested according to the CEA 

DAM test procedure)

Proposed values for Hm (in hours/day) would be as follows:

Hon = 7

Hstandby-passive = 17

Hoff = 0

To determine Hon, DOE obtained Nielsen TV viewing statistics for the months June 2010 

through May 2011.38 Nielsen collected between 48,791 and 52,105 samples in each month, from 

a representative cross section of U.S. households. DOE separated the data for each household to 

consider the primary TV. The mean viewing hours per day for primary TVs was determined for 

each month, and then the mean across the whole 12 months was taken to provide the final value. 

It was important to consider 12 months, not just one, as there is significant seasonal variation in 

viewing habits.

 

38 The Nielsen Company, LLC (2011).
114

It was assumed that the remainder of the time, TVs would be in standby-passive mode

(thus, Hstandby-passive = 24 – Hon), except for the case of TVs with DAM capability, where the 

average hours per day the TV is in DAM would also be included in the calculation. Therefore, 

Hoff = 0 is based on the assumption that virtually all TVs remain in standby mode rather than 

being physically switched off when not in use.

Note that Pon is itself a weighted average of measurements for units with automatic 

brightness control available:

Pon = P10 * W10 + P50 * W50 + P100 * W100 + P300 * W300

where:

Pi = on mode power measured at room illuminance of i lux

Wi = weighting at room illuminance i, expressed in percent.

Wi are proposed to be equally weighted (W10 = W50 = W100 = W300 = 25 percent). See 

Section IIIII.E.4.b.i for further discussion and explanation.

The advantage of using a single metric is that the approximate annual average energy 

consumption can be calculated within the test procedure. Although a single metric would require 

manufacturers to represent the efficiency of their TVs in a consistent manner, this is already 

being accomplished under the FTC Labeling Program for TVs as it is currently using this 
115

method. A single metric would help harmonize the different voluntary, incentive, and State 

programs applicable to TVs. However, the DOE proposed single metric would most likely 

eliminate the current energy efficiency standards for TVs established by California, since 

California established separate standards for both on mode and standby mode. All manufacturers 

would be required to make energy representations with the final DOE test procedure within 180 

days after publication. After that time, manufacturers would not be required to provide to

California separate results for on mode and standby mode in accordance with the California 

standard. This single metric would also require a change in the ENERGY STAR Program for 

TVs, since ENERGY STAR also has separate requirements for on mode, standby mode and 

DAM. The DOE proposed single metric would require DOE to monitor how the coefficients 

used to calculate the metric change with consumer usage and technological advancements in the 

TV market. For instance, the average number of primary TV viewing hours has increased by 

approximately 0.16 hours per day each year from 2007 to 2011, or 10 percent over four years. 

Additionally, the single metric considered in this NOPR does not distinguish between different 

usage profiles for calculating annual energy consumption for types of TVs with different features 

included in our TV definition, such as computer monitors over 30 inches. Finally, the proposed 

single metric does not capture all measurements in the test procedure such as power factor and 

illuminance ratio.

Although DOE is proposing multiple output metrics, it seeks comments from interested 

parties on both of the methods presented in this NOPR, including the use of a single metric for 

calculating annual energy consumption. (See Issue 13 in section V.E ”Issues On Which DOE 

Seeks Comment”).

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Order 12866

The Office of Management and Budget has determined that test procedure rulemakings 

do not constitute “significant regulatory actions” under section 3(f) of Executive Order 12866, 

Regulatory Planning and Review, 58 FR 51735 (Oct. 4, 1993). Accordingly, this action was not 

subject to review under the Executive Order by the Office of Information and Regulatory Affairs 

(OIRA) in the Office of Management and Budget (OMB).

B. Review under the Regulatory Flexibility Act

The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires preparation of an initial 

regulatory flexibility analysis (IFRA) for any rule that by law must be proposed for public 

comment, unless the agency certifies that the rule, if promulgated, will not have a significant 

economic impact on a substantial number of small entities. As required by Executive Order 

13272, “Proper Consideration of Small Entities in Agency Rulemaking,” 67 FR 53461 (August 

16, 2002), DOE published procedures and policies on February 19, 2003, to ensure that the 

potential impacts of its rules on small entities are properly considered during the DOE 

rulemaking process. 68 FR 7990. DOE has made its procedures and policies available on the 

Office of the General Counsel’s website: www.gc.doe.gov.

DOE reviewed today’s proposed rule under the provisions of the Regulatory Flexibility 

Act and the policies and procedures published on February 19, 2003. This proposed rule 
117

prescribes a test procedure to be used to develop and implement future energy conservation 

standards for TVs. DOE certifies that this proposed rule will not have a significant impact on a 

substantial number of small entities. The factual basis for this certification is as follows.

The Small Business Administration (SBA) considers an entity to be a small business, if, 

together with its affiliates, it employs less than a threshold number of workers specified in 13 

CFR part 121. The thresholds set forth in these regulations are based on size standards and codes 

established by the North American Industry Classification System (NAICS)39. TV manufacturers 

are classified under NAICS code 334220, “Radio and Television Broadcasting and Wireless 

Communications Equipment Manufacturing,” and are considered small entities if they employ 

750 employees or less.

DOE determined that most manufacturers of TVs are large multinational corporations. To 

develop a list of domestic manufacturers, DOE reviewed the Hoover database40 and other

publicly available data, including the Energy Star qualified TVs database. As a result of its 

review, DOE determined that there were no TV manufacturers who would qualify as small 

entities. DOE also notes that manufacturers are already required to use a test procedure similar to 

DOE’s proposed test procedure to make energy representations under the Federal Trade 

Commission’s EnergyGuide labeling program. 76 FR 1038. DOE’s proposed test procedure can 

be conducted concurrently with FTC testing without significant additional burden.

 

39 For more information visit: http://www.sba.gov/. The size standards are available at 

http://www.sba.gov/sites/default/files/Size_Standards_Table.pdf.

40 Hoovers. Web 12 Dec 2011. <http://www.hoovers.com/
118

Based on the above, DOE certifies that there would not be a significant impact on a 

substantial number of small entities and has not prepared an IRFA for this rulemaking. DOE 

transmitted the certification and supporting statement of factual basis to the Chief Counsel for 

Advocacy of the SBA for review under 5 U.S.C. 605(b). DOE requests comment on its 

conclusion that there are no small business manufacturers.

C. Review Under the Paperwork Reduction Act of 1995

There is currently no information collection requirement related to the test procedure for 

TVs. In the event that DOE proposes an energy conservation standard with which manufacturers 

must demonstrate compliance, DOE will seek OMB approval of such information collection 

requirement.

DOE established regulations for the certification and recordkeeping requirements for 

certain covered consumer products and commercial equipment. 76 FR 12422 (March 7, 2011). 

The collection-of-information requirement for the certification and recordkeeping was subject to 

review and approval by OMB under the Paperwork Reduction Act (PRA). This requirement was

approved by OMB under OMB Control Number 1910-1400. Public reporting burden for the 

certification was estimated to average 20 hours per response, including the time for reviewing 

instructions, searching existing data sources, gathering and maintaining the data needed, and 

completing and reviewing the collection of information.
119

As stated above, in the event DOE proposes an energy conservation standard for TVs 

with which manufacturers must demonstrate compliance, DOE will seek OMB approval of the

associated information collection requirement. DOE will seek approval either through a proposed 

amendment to the information collection requirement approved under OMB control number 

1910-1400 or as a separate proposed information collection requirement.

Notwithstanding any other provision of the law, no person is required to respond to, nor 

shall any person be subject to a penalty for failure to comply with, a collection of information 

subject to the requirements of the PRA, unless that collection of information displays a currently 

valid OMB Control Number.

D. Review Under the National Environmental Policy Act of 1969

In this proposed rule, DOE proposes a test procedure that it expects will be used to 

develop and implement future energy conservation standards for TVs. DOE has determined that 

this rule falls into a class of actions that are categorically excluded from review under the 

National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE’s implementing 

regulations at 10 CFR part 1021. Specifically, this proposed rule establishes a new test procedure 

without affecting the amount, quality or distribution of energy usage, and, therefore, would not 

result in any environmental impacts. Thus, this rulemaking is covered by Categorical Exclusion 

A5 under 10 CFR part 1021, subpart D, which applies to any rulemaking that does not result in 

any environmental impacts. Accordingly, neither an environmental assessment nor an 

environmental impact statement is required.
120

E. Review Under Executive Order 13132

Executive Order 13132, “Federalism,” 64 FR 43255 (August 4, 1999) imposes certain 

requirements on agencies formulating and implementing policies or regulations that preempt 

State law or that have Federalism implications. The Executive Order requires agencies to 

examine the constitutional and statutory authority supporting any action that would limit the 

policymaking discretion of the States and to carefully assess the necessity for such actions. The 

Executive Order also requires agencies to have an accountable process to ensure meaningful and 

timely input by State and local officials in the development of regulatory policies that have 

Federalism implications. On March 14, 2000, DOE published a statement of policy describing 

the intergovernmental consultation process it will follow in the development of such regulations. 

65 FR 13735. DOE has examined this proposed rule and has determined that it would not have a 

substantial direct effect on the States, on the relationship between the national government and 

the States, or on the distribution of power and responsibilities among the various levels of 

government. EPCA governs and prescribes Federal preemption of State regulations as to energy 

conservation for the products that are the subject of today’s proposed rule. States can petition 

DOE for exemption from such preemption to the extent, and based on criteria, set forth in EPCA. 

(42 U.S.C. 6297(d)) No further action is required by Executive Order 13132.

F. Review Under Executive Order 12988

Regarding the review of existing regulations and the promulgation of new regulations, 

section 3(a) of Executive Order 12988, “Civil Justice Reform,” 61 FR 4729 (Feb. 7, 1996), 

imposes on Federal agencies the general duty to adhere to the following requirements: (1) 

eliminate drafting errors and ambiguity; (2) write regulations to minimize litigation; (3) provide 
121

a clear legal standard for affected conduct rather than a general standard; and (4) promote 

simplification and burden reduction. Section 3(b) of Executive Order 12988 specifically requires 

that Executive agencies make every reasonable effort to ensure that the regulation: (1) clearly 

specifies the preemptive effect, if any; (2) clearly specifies any effect on existing Federal law or 

regulation; (3) provides a clear legal standard for affected conduct while promoting 

simplification and burden reduction; (4) specifies the retroactive effect, if any; (5) adequately 

defines key terms; and (6) addresses other important issues affecting clarity and general 

draftsmanship under any guidelines issued by the Attorney General. Section 3(c) of Executive 

Order 12988 requires Executive agencies to review regulations in light of applicable standards in 

sections 3(a) and 3(b) to determine whether they are met or it is unreasonable to meet one or 

more of them. DOE has completed the required review and determined that, to the extent 

permitted by law, the proposed rule meets the relevant standards of Executive Order 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) requires each Federal 

agency to assess the effects of Federal regulatory actions on State, local, and Tribal governments 

and the private sector. Pub. L. No. 104-4, sec. 201 (codified at 2 U.S.C. 1531). For a proposed 

regulatory action likely to result in a rule that may cause the expenditure by State, local, and 

Tribal governments, in the aggregate, or by the private sector of $100 million or more in any one 

year (adjusted annually for inflation), section 202 of UMRA requires a Federal agency to publish 

a written statement that estimates the resulting costs, benefits, and other effects on the national 

economy. (2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to develop an 

effective process to permit timely input by elected officers of State, local, and Tribal 
122

governments on a proposed “significant intergovernmental mandate,” and requires an agency 

plan for giving notice and opportunity for timely input to potentially affected small governments 

before establishing any requirements that might significantly or uniquely affect small 

governments. On March 18, 1997, DOE published a statement of policy on its process for 

intergovernmental consultation under UMRA. 62 FR 12820; also available at 

http://www.gc.doe.gov. DOE examined today’s proposed rule according to UMRA and its 

statement of policy and determined that the rule contains neither an intergovernmental mandate, 

nor a mandate that may result in the expenditure of $100 million or more in any year, so these 

requirements do not apply.

H. Review Under the Treasury and General Government Appropriations Act, 1999

Section 654 of the Treasury and General Government Appropriations Act, 1999 (Pub. L. 

105-277) requires Federal agencies to issue a Family Policymaking Assessment for any rule that 

may affect family well-being. This rule would not have any impact on the autonomy or integrity 

of the family as an institution. Accordingly, DOE has concluded that it is not necessary to 

prepare a Family Policymaking Assessment.

I. Review Under Executive Order 12630

DOE has determined, under Executive Order 12630, “Governmental Actions and 

Interference with Constitutionally Protected Property Rights” 53 FR 8859 (March 18, 1988) that 

this regulation would not result in any takings that might require compensation under the Fifth 

Amendment to the U.S. Constitution.
123

J. Review Under Treasury and General Government Appropriations Act, 2001

Section 515 of the Treasury and General Government Appropriations Act, 2001 (44 

U.S.C. 3516 note) provides for agencies to review most disseminations of information to the 

public under guidelines established by each agency pursuant to general guidelines issued by 

OMB. OMB’s guidelines were published at 67 FR 8452 (Feb. 22, 2002), and DOE’s guidelines 

were published at 67 FR 62446 (Oct. 7, 2002). DOE has reviewed today’s proposed rule under 

the OMB and DOE guidelines and has concluded that it is consistent with applicable policies in 

those guidelines.

K. Review Under Executive Order 13211

Executive Order 13211, “Actions Concerning Regulations That Significantly Affect 

Energy Supply, Distribution, or Use,” 66 FR 28355 (May 22, 2001), requires Federal agencies to 

prepare and submit to OMB, a Statement of Energy Effects for any proposed significant energy 

action. A “significant energy action” is defined as any action by an agency that promulgated or is 

expected to lead to promulgation of a final rule, and that: (1) is a significant regulatory action 

under Executive Order 12866, or any successor order; and (2) is likely to have a significant 

adverse effect on the supply, distribution, or use of energy; or (3) is designated by the 

Administrator of OIRA as a significant energy action. For any proposed significant energy 

action, the agency must give a detailed statement of any adverse effects on energy supply, 

distribution, or use should the proposal be implemented, and of reasonable alternatives to the 

action and their expected benefits on energy supply, distribution, and use. 
124

Today’s regulatory action to establish a test procedure for measuring the energy efficiency of 

TVs is not a significant regulatory action under Executive Order 12866. Moreover, it would not 

have a significant adverse effect on the supply, distribution, or use of energy, nor has it been 

designated as a significant energy action by the Administrator of OIRA. Therefore, it is not a 

significant energy action, and, accordingly, DOE has not prepared a Statement of Energy Effects.

L. Review Under Section 32 of the Federal Energy Administration Act of 1974

Under section 301 of the Department of Energy Organization Act (Pub. L. 95–91; 42 

U.S.C. 7101), DOE must comply with section 32 of the Federal Energy Administration Act of 

1974, as amended by the Federal Energy Administration Authorization Act of 1977. (15 U.S.C. 

788; FEAA) Section 32 essentially provides in relevant part that, where a proposed rule 

authorizes or requires use of commercial standards, the notice of proposed rulemaking must 

inform the public of the use and background of such standards. In addition, section 32(c) requires 

DOE to consult with the Attorney General and the Chairman of the Federal Trade Commission 

(FTC) concerning the impact of the commercial or industry standards on competition. 

The proposed rule incorporates testing methods contained in annex C.3 and section

11.5.5, 11.5.6, and 11.6 of the commercial standard, International Electrotechnical Commission 

62087 Edition 2.0 2011, “Method of Measurement for the Power Consumption of Audio, Video 

and Related Equipment;” section 5.3.1 of the commercial standard, International Electrotechnical 

Commission 62301 Edition 2.0 2011, “Household electrical appliances - Measurement of 

standby power” and CEA Procedure for Download Acquisition Mode Testing: For TVs,” 

Revision 0.3, September 8, 2010. DOE has evaluated these standards and is unable to conclude 
125

whether they fully comply with the requirements of section 32 (b) of the Federal Energy 

Administration Act (i.e., whether they were developed in a manner that fully provides for public 

participation, comment, and review).

As required by section 32(c) of the Federal Energy Administration Act of 1974 as 

amended, DOE will consult with the Attorney General and the Chairman of the Federal Trade 

Commission about the impact on competition of using the methods contained in these standards 

before prescribing a final rule.

E. Issues on Which DOE Seeks Comment

Although DOE welcomes comments on any aspect of this proposal, DOE is particularly 

interested in receiving comments and views of interested parties concerning the following issues: 

1. Scope of Coverage – DOE seeks comments from interested parties on the proposed scope 

of this rulemaking, as well as the definition of TVs. Specifically, DOE would like 

comments on including both TVs and displays greater than 15 inches which are sold with 

a TV tuner, and displays greater than 30 inches without a TV tuner in its definition. (See 

section III.C)

2. Light Measurement Devices – DOE seeks comments from interested parties on the LMD

equipment specifications proposed in this NOPR. (See Section III.D.1.c)

signal source and generation specified in this NOPR. (See section III.D.2.c)

4. Picture Settings to Test – DOE seeks comments from interested parties on its proposal to 

conduct luminance tests in home picture setting and retail picture setting. For testing on 

mode energy consumption, DOE seeks comment on its proposal to test in home picture 

setting, along with its consideration to test on mode in both the highest and lowest energy 
132

consuming picture settings (or brightest or dimmest), or all picture settings. (See section

III.E.1)

5. Luminance Testing – DOE seeks comments from interested parties on its proposed 

method of luminance testing. DOE also seeks comments on its proposal to include a 

luminance ratio. (See sectionIII.E.3.b)

6. Warm-up and Stabilization – DOE seeks comments on the proposed method of taking 

the luminance measurement immediately after displaying the three bar video signal. (See 

section III.E.3.a)

7. Video signal for Luminance Testing – DOE seeks comments from interested parties on 

its proposal to use the three bar video signal for luminance testing. DOE further seeks 

comments on any of the additional video signals that it considered. (See section III.E.3.c)

8. Room Illuminance Levels for Television Sets Shipped with Automatic Brightness 

Control Enabled – DOE seeks comments from interested parties on whether there should 

be a limit to the reduction in display luminance achieved from ABC, and how a 

minimally acceptable display luminance value should be established. DOE also seeks 

comment from interested parties on its proposal to test TVs shipped with ABC enabled at 

room illuminance levels of 10, 50, 100, and 300 lux. DOE additionally welcomes 

comments on how these outputs should be weighted and combined. (See section 

III.E.4.b.i)

9. Method for Creating Illuminance Levels for Television Sets Shipped with Automatic 

Brightness Control Enabled – DOE seeks comments from interested parties on the 

method for creating room illuminance levels including both the direct light method that it 

proposed in this NOPR and the diffused light method considered in this NOPR. DOE also 
133

seeks comments from interested parties on setting a color temperature range and a 

potential warm up period associated with other light sources in that range. (See section

III.E.4.b.ii)

10. Three Dimensional Display Testing – DOE seeks comments from interested parties on 

3D testing. DOE specifically seeks comment on its two methods under consideration for 

a future rulemaking which include converting the 2D IEC dynamic broadcast-content 

video signal to 3D using a real time converting Blu-ray player or creating a 3D version of 

the IEC dynamic broadcast-content video signal. DOE also seeks comments on how it 

can best work with the IEC and interested parties to promote the development of a 3D 

test procedure. (See section III.E.4.d)

11. Internet Connectivity – DOE seeks comments from interested parties on its consideration 

of testing the internet as part of on mode; standby-active, high mode; and standby-active, 

low mode. (See section III.E.4 for on mode and section III.E.5.c.ii for standby-active)

12. Standby and Off Modes – DOE seeks comments from interested parties on testing 

standby and off mode of TVs according to the procedure outlined, above. (See sections

III.E.5.c and III.E.5.d)

13. Single Metrics – DOE seeks comments from interested parties on the alternative 

approach of using a single metric for calculating annual energy consumption. DOE also 

seeks comment on its preliminary decision not to take into account the possibility that 

consumers may switch between preset picture settings. (See section III.E.6)

14. Input Format Hierarchy – DOE seeks comments from interested parties on the hierarchy 

of input formats required to connect the TV to a video source. (See section III.D.2.c) 
VI. Approval of the Office of the Secretary 

The Secretary of Energy has approved publication of this proposed rule.

power of the individual components without removing the product housing; and (b) the 

product connects to a wall outlet via a single power cord.

2. Accuracy and Precision of Measurement Equipment

3.1. Electrical Energy Supply

3.1.1. Power Supply. Carry out measurements using a power supply providing voltage 

of 115 V at 60 Hz. 
144

The fluctuation of the voltage supplied during the tests shall not exceed ± 1 percent. 

The frequency fluctuation and the harmonic components of the supplied power shall 

not exceed ±1 percent and 5 percent respectively.

3.1.2. Power Meter. The measurement shall be carried out directly by means of a 

wattmeter, a wattmeter with averaging function, or a watt-hour meter, by dividing 

the reading by the measuring time. For TVs for which the input video signal varies 

over time, use a wattmeter with an averaging function to carry out the measurement.

3.1.2.1. The sampling rate of the watt-hour meter or wattmeter with averaging 

function should be one measurement per second or more frequent.

3.1.2.2. The power measurement instrument used shall measure the power factor 

and the real power consumed regardless of the power factor of the device 

under test.

3.1.2.3. Power measurements of 0.5 W or greater shall be made with an 

uncertainty of less than or equal to 2 percent (at the 95 percent confidence 

level). Measurements of power of less than 0.5 W shall be made with an 

uncertainty of less than or equal to 0.01 W (at the 95 percent confidence level). 

The power measurement instrument shall have a resolution of:

0.01 W or better for power measurements of 10 W or less;
145

0.1 W or better for power measurements of greater than 10 W up to 100 

W;

1 W or better for power measurements of greater than 100 W.

3.1.3. Light Measurement Device. All LMDs shall have an accuracy of ±2 percent ± 2 

digits of the digitally displayed value and repeatability within 0.4 percent ± 2 digits 

of displayed value. LMDs must also have an acceptance angle of 3 degrees or less.

4. Test Room and Set-Up Criteria.

4.1. Installation. Install the TV in accordance with manufacturer’s instructions.

4.2. Dark Room Conditions. All luminance testing (with a non-contact meter) and on mode 

testing (with ABC enable by default) shall be performed in dark room conditions, 

meaning the display screen illuminance measurement in off mode must be less than or 

equal to 1.0 lux.

4.3. Ambient Temperature Conditions. For all testing, maintain ambient temperature 

conditions between 23 C ± 5 C.

4.4. Ambient Relative Humidity Conditions. For all testing, maintain the ambient relative 

humidity between 10 and 80 percent.
146

4.5. Input Cable. Testing shall be performed using an HDMI input cable. If the TV does not 

have an HDMI input, the following inputs shall be used, in the following order:

HDMI/DVI, VGA, component, S-Video, and composite.

4.6. 2D Testing Signal Source. The signal source shall be able to generate a Blu-ray signal.

5. Test Measurements.

5.1. For on mode and luminance testing, connect the signal source generator to the TV via 

the input cable.

5.2. Warm-up. TVs shall be warmed-up prior to testing using the IEC 62087-2011 

(incorporated by reference, see §430.3) dynamic broadcast-content video signal for at 

least one hour, found in annex C.3 of IEC 62087-2011. If the TV has not reached a 

stable state with respect to power within the one hour time period, the warm-up shall last 

until the TV reaches a stable state. For the purposes of this rulemaking, the TV is 

considered to be in a stable state if the average power consumption over two consecutive 

plays of IEC 62087-2011 dynamic broadcast-content video signal does not vary by 

more than 2 percent. 

5.3. Luminance Test.

5.3.1. Luminance Test. The luminance test shall be performed immediately following 

the warm-up period. The luminance test shall first be performed with the TV in the 
147

retail picture setting, followed by the TV in home picture setting. The ABC sensor 

must be disabled during this test.

5.3.1.1. LMD Setup. Align the LMD perpendicular to the center of the display 

screen. If a distance meter is being used for testing, the LMD shall be at a 

distance capable of achieving the desired specifications outlined in section 

3.1.3.

5.3.1.2. Three Bar Video Signal Measurement. The TV shall be measured in both 

the home and retail picture settings using IEC 62087-2011 (incorporated by 

reference, see § 430.3) three bar video signal found in section 11.5.5 of IEC 

62087-2011. Record the luminance immediately after the three bar video signal 

is displayed in the retail picture setting first, as Lretail, followed by the home 

picture setting as Lhome. 

5.4. On Mode Test for TVs without ABC Enabled By Default.

5.4.1. On mode testing shall be performed with the TV in home mode, while displaying

the full 10-minute duration of IEC 62087-2011 Blu-ray dynamic-broadcast video 

signal (incorporated by reference, see §430.3). Measure the energy consumption and 

record the value as Pon.

5.5. On Mode Test for TVs with ABC Enabled By Default. The following test shall be 

performed if the TV is shipped with ABC enabled by default:
148

5.5.1. On mode testing shall be performed with the TV in home mode, while displaying 

IEC 62087-2011 Blu-ray dynamic-broadcast video signal for 10 minutes 

(incorporated by reference, see §430.3) with l0 lux (± 1 lux) entering the ambient 

light sensor. Measure the energy consumption and record the value as P10. Repeat 

the measurements with 50 lux (± 2 lux), 100 lux (± 5 lux), and 300 lux (± 9 lux)
