Actually it's 100% to 300%, but never mind. It's not about confidence,
it's whether another approach is better.
As a former NRTL (noninspecting) employee, I was subjected to noise
from some manufacturer's about how intrusive quarterly inspections
were.
Yes, they are; my point is that they aren't a good way to control
conformity either.
I suspect there's no system that will satisfy all players.
I'm sure we can agree on that!
With self-certification, the appropriate action is to determine whether
the product is still compliant when the XY23C is introduced, or when the
substitution is discovered, with tests if necessary, and if it is, no
further action is necessary.
At another former employer, I heard a story of a moderately large piece
of rack mountable equipment designed by an European subsidiary intended
for the
European market that could not be brought into
compliance with radiated emissions limits using
standardized test methods without significant
revisit to the drawing board. Their solution?
Place the unit on its back. Et voila! A self
certification was emitted.
If the product was going to Germany or Austria, there is a risk that the
product would be rejected by active surveillance. In other countries, it
would only be rejected if it actually caused interference. Autre pays,
autre moeurs.
