Richard, I have a lot of sympathy with the advice you gave to Maria, but there are some problems with what you wrote in your message yesterday:
<SNIP> > >For the purposes of the LVD, I suggest you consider >that your product and the wall adapter are two, >independent products, an electronic keyboard, and a >wall adapter. > >Your electronic keyboard product is exempt from the LVD >because it operates from a source less than 50 V. >However, it is probably beneficial to use the CE mark >for the purposes of not having to justify why your >keyboard product product does not need the CE mark. You can't do this. According to the UK Department of Trade and Industry (DTI) if the equipment is supplied with an adapter which makes it possible to run it from the mains, you must consider the entire system as one assembly for the purposes of CE marking under the LVD. The only way to avoid CE marking the low voltage part of the system is to sell is completely separately from the power supply, and even then if you sell a supply as well to go with it, you're not really staying within the spirit of the requirements and may well get caught out. And anyway, the keyboard needs the CE mark under the EMC Directive whether or not it's sold with or without a power supply. <SNIP a load of good advice I do concur with> >This question raises the issue of "compatibility" of the >different safety standards, in this case EN 60065 and >EN 60950. There SHOULD be NO DIFFERENCES. There SHOULD >BE ONE STANDARD for power supplies, regardless whether >the supply is for home appliances or for IT equipment, or >any other equipment! There is, it's called EN61558, and the particular requirement that Maria needs is EN61558-2-6, "particular requirements for safety isolating transformers for general use".
