If you are actually refering to EN 60950:1992 + A2, the date in CC paragraph is listed as March 2000, so any certification may no longer be valid.
Assuming the standard used for the investigation is still valid, I would still assume that , due to annex C, withstand test levels, and other national deviations (UL is more sensitive to flame rating of materials), that you would still have to do some additional testing before a NRTL would recognize the unit. Note that any test data that does not clearly indicate that there is no fire hazard with all materials and construction would be suspect. If you have a CB report for the unit, submit it to UL and see what they say.... I speak only for myself.

In other words, is IEC60950 (1992) 2nd edition still valid for UL approval
