Amund - I forgot to mention: or against the requirements in CSA22.2 No 60950-1-03/UL60950-1 (publication dated 1APR2003). This should be your preferred standard for Canada and the US, going forward.

On the bright side, there were not very many changes to either IEC60950 or the CSA/UL standard that would negatively effect a power supply, so chances are good that it will comply, provided the individual safety critical components meet the mandatory requirements in Annex P.1.

RE: IEC60950 (1992) 2nd edition 3/31/03 I do know that for Telecom Power Distribution Units that Listed Circuit Breakers will now be required in place of Supplementary Protectors which were allowed under UL1950.

RE: IEC60950 (1992) 2nd edition
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.
