RE: IEC950 vs. EN 60950
Tania, We have not harmonized US safety mark demonstrating compliance with UL1950: UL, ETL, NRTL. I've been asked a rhetorical question which US mark is better. Europeans have at least a single CE mark which, in addition, covers EMC.

IEC950 vs. EN 60950
Daniel, IEC950 and EN60950 are technically the same standards. The EN is a copy of IEC 950 with some common modifications. If you have the EN standard, these modifications are marked with a vertical line in the margin. Pierre SELVA SMEE Actions Mesures - This message is coming from the emc-pstc discussion list.

RE: IEC950 vs. EN 60950
When a country adopts IEC950, it is sometimes necessary for that country to introduce national deviations due to local laws or conditions.
