Amund, To add to Peter's message why you need to purchase one or both of these standards:
1.) UL1950 (now UL60950) is based on IEC 60950 and, while identical to the IEC document, also specifies mandatory requirements to meet the U.S. and the Canadian National Electrical Codes. These NEC requirements may, in certain cases, disagree with the IEC requirements. 2.) EN 60950 is identical to the IEC 60950, however, it also specifies EC member country deviations which the IEC document does not address. Thus, if you are shipping to European EC countries, you need the EN document. If you are shipping in North America and world-wide, you should be able to get by with just the UL standard, since it follows the IEC document faithfully and shows deviations and/or additions by crossing out requirements where not applicable and inserting new requirements shown underlined. However, since the UL document is based on the IEC document, I prefer to order the IEC latest edition as soon as it is released to get a heads-up knowledge of how the new requirements might/will affect our domestic market. UL will then shortly up-date their standard to reflect the new requirements. Now you find that you bought all three standards!!!

You will need to buy a copy of the standard to get the full picture. It is not simple enough to place in an e-mail. Regards, Peter L.
