Tac & PSNet,
Altho we've discussed this here at some length before, the
certification and marking of components is intended to simplify the
evaluation and certification of equipment because the component doesn't
have to be evaluated again.
This works well if the test house that is certifying the equipment
accepts the certification of the component at face value. My experience is
that the 800 pound gorilla test house will only accept those certifications
from test houses with which it has a contractual MRA; meaning that most
other certifications aren't worth much... The converse is not universally
true... so, for component suppliers, don't waste your time looking for
clever alternatives to component certifications... you'll spend more time
than it's worth helping many of your customers trying to get around
re-evaluating your component in their application as part of their product
certification program...
