With regard to the EU EMC Directive, can anyone recommend a rule of
thumb for when it can be said that equipment is a) incapable of
generating or contributing to electromagnetic emissions which exceed a
level allowing radio and telecommunication equipment and other equipment
to operate as intended; and

b) it will operate without unacceptable degradation in the presence of
the electromagnetic disturbance normally consequent upon its intended
use?

 

My rough guess for a) is that it is fair to claim if the equipment
emissions are below 20% of the limit line for the same group & class of
equipment.

My rough guess for b) is that it is fair to claim if the equipment has
operated in its intended environment without known errors due to
electromagnetic disturbance. 

 

The thesis I am exploring here is that an known EMC emitter is not
necessarily in scope of the EMC directive if Article 1.3 is valid, and
what is a sound way to test its validity. 

 

Although I cannot find it explicitly in the RTTE directive, I wonder if
there is a similar concept in practice - radio equipment having such low
power levels such that they are considered benign?
