Title: ENERGY STAR® TV Data Collection Worksheet
Date: April 2, 2007

Description: The following spreadsheet is separated into seven sections: Test Info, Product Description,
Display, Inputs and Other Features, UL AC Input Rating, Standby Power, and Active Power. There is a
placeholder for the tester to add additional notes or comments about the test. The tester is provided a scroll
down list for product type, display type, display category, resolution format, aspect ratio, and POD present.
Formula-driven cells are locked/protected.

Instructions to Accompany use of Draft IEC 62087: Methods of Measurement for the Power

   Consumption of Audio, Video and Related Equipment for ENERGY STAR TV Testing

Files Needed to Conduct Testing
1. Draft IEC 62087: Methods of Measurement for the Power Consumption of Audio, Video and
    Related Equipment
2. Accompanying test-clips of dynamic broadcast-content and Internet-derived content
    (available by request only to those companies that anticipate conducting product-testing to be
    shared with EPA to aid in the ENERGY STAR TV specification revision)
3. IEC 62301: Household Appliances - Measurement of Standby Power

Instructions for Standby Mode Testing
When measuring TVs for standby power consumption, please reference the test standard IEC
62301: Household Appliances - Measurement of Standby Power.

EPA is aware that certain user-accessible settings can result in different levels of standby power
consumption. In an effort to identify which features cause higher levels of standby power
consumption, EPA is requesting that manufacturers measure standby both at factory default
settings and using any modified settings that would result in higher or lower standby power
consumption than the factory default settings. Corresponding fields for these measurements are
provided in the accompanying ENERGY STAR TV Data Collection Worksheet, along with space
to describe the features that are known to cause multiple levels of standby power.

Instructions for Active Mode Testing
To measure the active mode power consumption of a TV set, EPA requests that manufacturers
use the draft revision of the standard IEC 62087: Methods of Measurement for the Power
Consumption of Audio, Video and Related Equipment and its section 11, “Measuring conditions of
television sets for On (average) mode.”

Below, EPA provides specific guidance on how the test method should be implemented since the
draft test standard includes multiple methods for measuring TV active mode power. For ENERGY
STAR-related testing, the following exceptions and clarifications apply:
1. Section 11.3.9, “Accuracy of input signal levels” reminds testers that video inputs used for
    testing should be within +/- 2% of reference white and black levels. Section B.2 of Annex B,
    “Considerations for On (average) mode television set power measurements” describes the
    importance of input signal accuracy in further detail. EPA would like to emphasize the
    importance of using accurate/calibrated video inputs during active mode testing. We
    encourage the use of digital video signals such as HDMI wherever possible. When using
    analog inputs, manufacturers are urged to use DVD player equipment with highly accurate
    analog outputs that are within +/- 2% of reference signal levels.
2. Manufacturers should ignore section 11.4, “On mode (average) testing with static video
    signals” for the purposes of ENERGY STAR testing. EPA intends TVs to be measured using
    the dynamic video test signals referred to in section 11.5, “On mode (average) testing with
    dynamic broadcast-content video signal” and the Internet-derived content referred to in
    section 11.6, “On mode (average) testing with Internet-content video signal.” There are fields
    in the accompanying ENERGY STAR TV Data Collection Worksheet to capture the average
    power consumption for broadcast and Internet content.
3. Due to increased awareness of the importance of power quality on the part of EPA and
    electric utilities, we request that manufacturers indicate the true power factor of their sets
    during active mode measurement. A corresponding field is provided in the accompanying
    ENERGY STAR TV Data Collection Worksheet for this data.

     during active mode measurement. A corresponding field is provided in the accompanying
     ENERGY STAR TV Data Collection Worksheet for this data.
4.   In measuring the active mode power consumption of TVs, EPA is interested in capturing first
     and foremost the power consumption of products as they are shipped from the factory. Any
     sections of IEC 62087 that instruct the tester to modify factory default settings should be
     ignored when conducting initial active mode measurements on a given piece of equipment.
     These include sections 11.3.4, “Special functions” and 11.3.5, “Power saving functions.”
5.   If an automatic brightness control exists and is enabled by default, the TV should be tested in
     a room with a minimum ambient light level of 300 lux, as described in section 11.3.5, “Power
     saving functions.”
6.   EPA encourages manufacturers to submit multiple iterations of active mode tests for a given
     device to help EPA better understand the effect that certain non-default settings and features
     might have on active mode power consumption.
     Example: How might the power consumption of the set differ if a picture burn-in feature,
     otherwise enabled by default, were turned off by the user? Please refer to Annex B for
     guidance on measuring power-saving features. Manufacturers should use their discretion as
     to which features might have the greatest impact (increase or decrease) on active mode
     power consumption. Additional tests should be listed on a separate line from the original
     “factory default” test in the accompanying ENERGY STAR TV Data Collection Worksheet.
7.   At a minimum, EPA requests that manufacturers conduct an additional measurement of the
     set using whichever factory preset picture settings (e.g. movie, pro or other picture presets
     accessible through the on-screen menu) result in the lowest active mode power consumption,
     and list this additional measurement of the set on a separate line from the original “factory
     default” test in the accompanying ENERGY STAR TV Data Collection Worksheet.
