Prior to the EMC Directive, Germany required Class A ITE to be licensed.
Article 6 of the EMC Directive gives the right to a country to control
EMC compatibility by limiting the use of equipment at various sites.
This appears to allow countries to limit the use of Class A equipment.
Of course, the

Eric Lifesey nicely summarized the requirements of IEC (also EN) 61326 in his

covered in the emission section of the standard. The emission

Does anyone know where I can find a chart showing which EN or IEC EMC

Attached is a chart, in WordPerfect 6.1 format. You should also be able to

Firstly, I do not think that the EN has been listed in the Official
Journal (OJ) and so cannot be used (yet) to show compliance with the EU

As far as test plans go, they are required by the IEC 801 and EN61000

Hello from San Diego:
Eric Henning asks about clearance distances from an insulated
component to a grounded enclosure.
The issue is: What safety class is the insulation?
Insulation safety classes are:

These tests are tucked into the emission limits table (Table 4 on page 29)
