Hello all,
My copy of BS EN 60950-1:2006 has no clause 2.7.4 is this correct or an
omission? I can't find any indication of what has happened to it.
Also after clause 2.7.1 there is a statement detailing that 'This subclause
has been declared void'
Is this a clause numbering error which has

Yes, I have. These are custom mains transformers inherited from a former
division of our company. I often wondered why the detail drawings required
them to be CE marked. I have been removing that requirement as we specify new
transformers. In fact, I would truly like to come up with a
FWIW, some of my component xfmrs that are certified to 61558-x bear the

the certificate and test report.

Don,
Yes, I've certainly seen a CE marking on internal transformers. I would not
say that it is necessarily universal practice, but it certainly exists. In
such a case, I would expect the harmonised standard to be one of the parts of
EN 61558.

There is a great deal of information about Kapton wire on the internet. Some,
of course, extols its properties, but much condemns it, particularly for use
