U.S. DOE 430 has the test method, which is cited for ErP stuff. 'VI' has lower standby and higher efficiency per MEPS limits than 'V'.
Back to the OP. Type test conditions for ac mains input; that is, mains tolerances follow. IEC61010-1, IEC60601-1 (Cat II), IEC62368-1 ±10% of rating UL1012, UL5085, CSA66.x, CSA107.1, UL1741 120V for any rating up to 120V, 240V for rating 220 to 240V, and others per clause 39 CSA250.13 +10% rating Klingon 60950-1.1 any random voltage from 42V to 1500V Brian From: Richard Nute [mailto:ri...@ieee.org] Sent: Wednesday, April 12, 2017 12:00 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] Voltage Rating vs Voltage Specification Hi Scott: Thanks for the reference. However, “This mark does not serve as a consumer information label, but rather demonstrates the performance of the EPS when tested to the internationally supported test methods.” Hmm. If the mark does not serve as a consumer information label, who is it for? Bragging mark (to other power supply manufacturers)? My power supply is marked “V.” This appears to be more stringent than “VI.” True?

Current US requirement is level VI. You can download more info from the DOE here.
