Amund,
I don't think the discussion reached a consensus. An early book on the
subject,
Chris Marshman. The Guide to the EMC Directive. 1992:IEEE Press,
Piscataway NJ 308p.,
identified 'Communauté Européen' as the reason for 'CE' (p11 of
Introduction).
Some explainations are anachronistic.
We had a short discussion last autumn about the abbreviation of 'CE'.
CE... That would mean 'Caveat Emptor', right?

The prevailing ITE safety standards (e.g. IEC 60950) require markings

Hi Dave,
The EN 60950 you referenced below is actually EN/TRF 60950, which is a Test

TRF. It consists of only 38 pages, so it cannot be the whole standard. However,
I do share your
sentiment about poorly reproduced copies, whoever I may get (er, buy) them from.

warranty period than the rest of the chamber.

Not sure about practical, but ISO 11452 Part 3 describes the calculation method

It uses the formula
