Don't think so Roger. IEC 950 = EN 60 950, was meant for Information Technology Equipment, including Electrical Business Equipment.
EN 41 003 has a checkered history, but was mainly intended to provide additional requirements for any type of equipment that connects to a Telecom network. That could be Informatlon technology equipment or a coffeepot that is started via a telephone line. Indeed, EN 41 003 is pretty much Clause 6 of IEC 950, so far. The scientists have now put much of the content of Clause 6 of IEC 950, throughout the body of that Publication, so that it is no longer immediately obvious that something is or is not Telecom related by virtue of it being in Clause 6. UL 1459 is definitely NOT included in UL-1950. UL-1459 was the first UL try to create a Telecom equipment standard, based on UL-114. This was going on at about the same time that CSA was involved in a similar endeavour, first C22.2 No. 0.7 and later C22.2 No. 225. There was a bit of an effort to keep UL-1459 and CSA 225 more or less compatible, till it struck the membership as ludricous to keep this construct, while the rest of the world was moving to IEC-950 for these converging technologies. Hence, the BiNat Task Force created the BiNat or Binational standard, issued by both UL and CSA as UL-1950 and CSA C22.2 No. 950, identical. The price is comparable and you'll have to decide on what logo has more appeal when you go out to buy a copy. The BiNat is also BiCult in that it not only covers two nations, the US and Canada, it also covers two cultures, Information Technology and Telecommunications Technology. The document is based on IEC-950 with a number of deviations imposed by the National Electrical Codes of the USA and Canada and the much reviled "overvoltage" requirements which try to account for the fact that in much of North America, electricity and telephone service is brought to the residence via "pole lines", where the telephone cable runs on the same Poles as the Electrical wiring, giving rise to a certain amount of induction as well as the possibility of high power getting on to the telephone cable in cases where the electrical wire breaks and falls onto the telephone cable.
