UL 498 is generally more restrictive for plugs and receptacles than 60950-1. UL 498 is written to cover plugs and receptacles for general use. As such, it has to anticipate the use and abuse of the general environment. 60950-1.
It may be a moot point if you have a product to be sold in the United States. UL 60950-1 Annex P.1 notes that UL 498 shall be used for attachment plugs and receptacles instead of IEC 60320.

From: Goedderz, Jim [mailto:[email protected]] Sent: Tuesday, November 17, 2009 8:19 AM To: [email protected] Subject: EN60320 vs UL498 appliance inlet To all you safety knowledgeable peers, We are trying to do a comparison between UL498 and EN60950-1 on an appliance inlet, no fuses. Can anyone get the ball rolling for us by relating if they are equivalent, or if one is more stringent? Since they are not harmonized, my first guess is that they have some non reconcilable differences. The bottom line may be, can we use a UL498 recognized part to meet the requirements of EN60950-1 2nd ed.? Thank you for any input.
