Martin,
While I may disagree with some of the technical content of various standards
(I think they need to add more details to accommodate smaller, more
distributed systems), I heartily agree with the need for them. The immunity
tests in particular represent real-world threats to equipment, and a lot of
electronics out there are only marginally compliant, in spite of the
approvals marked on the case. I've had several instances where third party
devices failed permanently when used as part of setups for immunity tests.
They probably passed testing only in certain ideal configurations that don't
represent actual field installations.

Subject: The wisdom behind all these standrads
I've been reading messages from this list for several months,
and I see many questions about how to comply with the long list
of EMC standards. Yet, I can't recall anyone ever questioning
the appropriateness of any standard. That is, should the
standand add value to a product or to those who use it? Is it
that the EMC engineer's place is not to question the wisdom of a
standard's value, but simply to make products with those
standards, whether or not we agree with the intent of those
standards? That's not to say that these regulations are bad.
Maybe they're good because they make the world a better place
for those who use electronic products.
Just wondering.
