5. Title, number of pages and language(s) of the notified document:  Energy 
Conservation Program: Test Procedure for External Power Supplies  
6. Description of content:  The U.S. Department of Energy ("DOE") is proposing to revise 
its test procedure for external power supplies ("EPS" or "EPSs"). DOE is proposing to add 
a definition for "commercial and industrial power supply" in its regulations to differentiate 
between EPSs and other non -consumer power supplies that are not subject to the test 
procedure. DOE also proposes to add a definition to address an adaptive EPS that 
conforms to the Universal Serial Bus Power Delivery ("USB -PD EPS") specifications and 
revise its procedure to address their testing in a manner more representative of their 
actual use. Further, the proposed revisions would provide more specific instructions  for 
testing single -voltage EPSs that have multiple output busses. Lastly, DOE proposes to 
reorganize the test procedure to centralize definitions, consolidate generally applicable 
requirements, and better delineate requirements for single -voltage, multipl e-voltage, and 
adaptive EPSs. DOE is seeking comment from interested parties on the proposal.  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  Protection of the environment; Harmonization
