Hi John,

I agree with your view; which I understand to be.

1.  Nobody can paraphrase an entire standard in a email without huge
chances for error... and
2.  A company should buy the standard if they plan on using it.

This reminds me of a thorn in my side which I hope will get the
attention of those that deal in standards.  I know I have a reputation
for being "stumpish", so I'll keep it short.  

 The thorn is...  I believe that the at least the scope statement of any
standard should be public information that can be accessed as part of
the regulatory body websites (whether it's CENELEC, ACA.... whoever).
There should also be no fear of people being whacked for copywrite
violations because they share the scope statement from a standard.
Sometimes, the title just isn't descriptive enough.

We do purchase standards that we know will apply to our products.
However; I have been burned by buying standards that sounded like they
would apply; but really don't.

I assume that a few others have had similar experiences; and that's why
we see so many questions in the EMC-PSTC regarding standards
applicability.  Some companies do care about the cost of that $75
standard.

(definitely not the opinions of my employer...)
