Description:  TITLE: Energy Conservation Program: Test Procedure for External Power Supplies  
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy  
ACTION: Final rule  
SUMMARY: This final rule amends the current U.S. Department of Energy test procedure for external 
power supplies by clarifying the scope of the test procedure more explicitly, providi ng more specific 
instructions for testing single -voltage external power supplies with multiple -output busses and 
external power supplies shipped without an output cord, providing instructions allowing for

  functionality unrelated to the external power suppl y circuit to be disconnected during testing so long 
as the disconnection does not impact the functionality of the external power supply itself, specifying 
test requirements for adaptive external power supplies that conform to the industry -based Universal 
Serial Bus Power Delivery specifications consistent with current test procedure waivers that DOE has 
already granted for these products, and reorganizing the test procedure to centralize definitions, 
consolidate generally applicable requirements, and better  delineate requirements for single -voltage, 
multiple -voltage, and adaptive external power supplies.  
DATES: The effective date of this rule is 19 September 2022. The final rule changes will be 
mandatory for product testing starting 15 February 2023. The inc orporation by reference of certain 
other publications listed in this rule was approved by the Director of the Federal Register on 24 
September 2015.
