with an end-use device that is certified to any of the following standards would not meet the EPCA definition of an EPS:
A CISPR 11 Class A Equipment, Industrial, scientific and medical equipmentRadio-frequency disturbanceLimits and methods of measurement;
B UL 1480A, Standard for Speakers for Commercial and Professional Use;
C UL 813, Standard for Commercial Audio Equipment; and D UL 1727, Standard for Commercial Electric Personal Grooming Appliances; or ii Such device being excluded or exempted from inclusion within, or conformance with, a law, regulation, or broadly-accepted industry standard where such exclusion or exemption applies only to non-consumer products;
7 A power supply distributed in commerce for use with an end-use device where:
i The end-use device is not a consumer product, as evidenced by either the circumstances in paragraph 6i or ii of this definition; and ii The end-use device for which the power supply is distributed in commerce is reasonably disclosed to the public, such as by identification of the end-use device on the packaging for the power supply, documentation physically present with the power supply, or on the manufacturers or private labelers public website; or 8 A power supply that is not marketed for residential or consumer use, and that is clearly marked or, alternatively, the packaging of the individual power supply, the shipping container of multiple such power supplies, or associated documentation physically present with the power supply when distributed in commerce is clearly marked FOR USE WITH
COMMERCIAL OR INDUSTRIAL
EQUIPMENT ONLY or NOT FOR
RESIDENTIAL OR CONSUMER USE, with the marking designed and applied so that the marking will be visible and legible during customary conditions for the item on which the marking is placed.

External power supply means an external power supply circuit that is used to convert household electric current into DC current or lower-voltage AC current to operate a consumer product. However, the term does not include any commercial and industrial power supply as defined in this section, or a power supply circuit, driver, or device that is designed exclusively to be connected to, and power

1 Light-emitting diodes providing illumination;
2 Organic light-emitting diodes providing illumination; or 3 Ceiling fans using direct current motors.

3. Section 430.23 is amended by revising paragraph bb to read as follows:
430.23 Test procedures for the measurement of energy and water consumption.

bb External Power Supplies. The energy consumption of an external power supply, including active-mode efficiency expressed as a percentage and the no-load, off, and standby mode energy consumption levels expressed in watts, shall be measured in accordance with appendix Z of this subpart.

4. Appendix Z is revised to read as follows:

This appendix covers the test requirements used to measure the energy consumption of external power supplies subject to the energy conservation standards set forth at 430.32w1.
3. Definitions: The following definitions are for the purposes of understanding terminology associated with the test method for measuring external power supply energy consumption.
Active mode means the mode of operation when the external power supply is connected to the main electricity supply and the output is or all outputs are for external power supplies with multiple outputs connected to a load or loads for external power supplies with multiple outputs.
Active mode efficiency is the ratio, expressed as a percentage, of the total real output power produced by a power supply to the real input power required to produce it.
IEEE Standard 15152000, 4.3.1.1 Reference for guidance only, see 430.4.
Active power P also real power means the average power consumed by a unit. For a two terminal device with current and voltage waveforms it and vt, respectively, which are periodic with period T, the real or active power P is:

Appendix Z to Subpart B of Part 430
Uniform Test Method for Measuring the Energy Consumption of External Power Supplies Note: Starting on 180 days after publication of the final rule in the Federal Register, manufacturers must make any representations regarding the energy efficiency or power consumption of external power supplies based upon results generated under this appendix. Prior to that date manufacturers must make any representations regarding the energy efficiency or power consumption of external power supplies based upon results generated under this appendix as it appeared at 10 CFR
part 430, subpart B revised as of January 1, 2021. The provisions at section 4g2 of this appendix regarding the testing of units for which a wire or cord is not provided by the manufacturer are not required for use until such time as compliance is required with any amended standards for external power supplies provided in 430.32w that are published after January 1, 2021.
1. Incorporation by reference DOE incorporated by reference the entire standard for IEC 62301 in 430.3; however, only enumerated provisions of this document are applicable to this appendix, as follows:
a IEC 62301, IEC 62301, Household electrical appliancesMeasurement of standby power, Edition 2.0, 201101, as follows:
i Section 4.3.2 Supply voltage waveform;
ii Section 4.4.1 Power measurement uncertainty;
iii Section 5.3.3 Average reading method;
iv Annex B Notes on the measurement of low power modes; and v Annex D Determination of uncertainty of measurement.
b Reserved.

Adaptive external power supply means an external power supply that can alter its output voltage during active-mode based on an established digital communication protocol with the end-use application without any user-generated action.
Ambient temperature means the temperature of the ambient air immediately surrounding the unit under test.
Average Active-Mode Efficiency means the average of the active mode efficiencies at the loading conditions 100%, 75%, 50%, and 25% of unit under tests nameplate output current for which that unit can sustain the output current.
Manual on-off switch is a switch activated by the user to control power reaching the device. This term does not apply to any mechanical, optical, or electronic switches that automatically disconnect mains power from the device when a load is disconnected from the device, or that control power to the load itself.
Minimum output current means the minimum current that must be drawn from an output bus for an external power supply to operate within its specifications.
Multiple-voltage external power supply means an external power supply that is designed to convert line voltage AC input into more than one simultaneous lowervoltage output.
Nameplate output current means the current output of the power supply as specified on the manufacturers label on the power supply housing either DC or AC or, if absent from the housing, as provided by the manufacturer.
Nameplate output power means the power output of the power supply as specified on
