For the -1, 2nd ed, see http://www.ul.com/hitech/ite/60950-1_2ndEd_Analysis_Nov14_07.pdf I might have some comparison documents archived for older editions that I'll look for on request.

RE: UL60950 vs. IEC 60950
David Unfortunately, I do not know of any comparison. However, the first reason why you cannot use UL60950 for compliance with the LVD is that it is not an EN standard, and also incorporates the US National Deviations, so is different in some areas from the EN version. That said, if you demonstrate compliance to IEC 60950-1 with ALL national deviations included, then you should be compliant with both UL60950-1 and EN60950-1, but you may still need the independent test reports citing those standards to be able to prove this to regulatory authorities. This is not too difficult to achieve, just placing a few additional requirements on some of the components and materials that you use. Best regards Neil R.

RE: UL60950 vs. IEC 60950
Hi Dave, Technically speaking your subject line should’ve been UL60950-1 vs. EN60950-1 given your query. Anyway, without going into detail you only have to look at these standards to see the differences between them and from IEC60950-1, in particular: UL60950-1: Preface listing 6 types of deviations and Annexes NAA - NAE EN60950-1: Annexes ZA - ZC Actually, a CB Scheme investigation against IEC60950-1 addressing all national deviations should be the basis of acceptance in both the US and the EU. If you would like to discuss this further off-line, please let me know.

RE: UL60950 vs. IEC 60950
The UL standard will highlight differences from the base (IEC) standard. The EN standard will also highlight differences from the base (IEC) standard. Another thing you could do is get the latest CB bulletin for OFF from the IECEE, which will list published national and group differences. You can get a 12 month subscription for about US $100. If the link below works, it gives a preview as to what the bulletin has in it: http://members.iecee.org/iecee/ieceemem ers.nsf/vScopebyStdCatOnly?OpenViewSBV=OFF Scott Aldous Compliance Engineer Advanced Energy Tel: 970-407-6872 Fax: 970-407-5872 From: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of Ron Pickard, RPQ Sent: Thursday, May 08, 2008 8:06 AM To: david.cole...@selex-comms.com Cc: emc-p...@ieee.org Subject: RE: UL60950 vs. IEC 60950 Hi Dave, Technically speaking your subject line should’ve been UL60950-1 vs. EN60950-1 given your query.

RE: UL60950 vs. IEC 60950
Two other general points, even apart from the deviations made by UL from the IEC version: 1) For EU, you need to meet the EN edition, which may also vary from the IEC edition. 2) Unless you specifically asked, the NRTL that evaluated the product to the UL standard may have only evaluated the product for operation at 120V 60Hz. But you may be selling the product for use at 230V 50Hz. Even assuming there are no component changes (between the model evaluated and the model sold in EU), you may need to re-evaluate the insulation, overcurrent protection and spacings. PS: One major deviation that applies to all UL standards is that they require COMPONENTS to meet applicable UL standards. Whereas the IEC and EN editions require that components meet the applicable IEC, EN or HD standards. This can be a huge difference, for example power cords, fuses, etc. Regards, Glyn Garside - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
