I entirely agree, and compliance must be designed in, not imposed after
the design is 'finished'. It isn't finished. I don't mention CISPR
emission standards, because the applicable standard depends on the type
of device, and we are not told that. So only a list is possible:
standards produced by CISPR B, CISPR F, CISPR I, and, if none of them is
applicable, the Generic Emission standards produced by CISPR H. These do
not include very short-range requirements.

Thanks John, I was the one who mentioned OATS under an assumption that
if doing very close distant compliance measurements then far field
measurements might also need consideration for EMC emissions.
The first question for any company producing an electrical product
should be, “what regulatory compliance is in place for our product
type in countries X, Y, Z ? ” That should be the starting point and
then the details follow from there and then, eventually, a
presentation discussion to a “CEO” or senior executive management
about how much it will cost to offer a complain device in the market
space of greatest opportunity. Then finance and market need to
determine ROI and opportunity cost.
It should be a harmonious and balanced effort between marketing,
engineering, and finance depts.

This is in reply to Jim Bacher's post, when has been tagged,
incorrectly of course, as SPAM.
The ICNIRP documents are scientific reports recommending limits of
exposure to electromagnetic field is the context of *human health*. I
may have been misled by Brian Kunde's use of 'EMF', so directed him to
the IEC standards based on the ICNIRP recommendations. If the context
is*electromagnetic compatibility*, and it is emissions that are to be
measured, not immunity, the standards produced by IEC SC77A might be
more applicable, but treatment of 'very close distances' is rare. Some
responders have not noticed the words '*very close distances*', and
have discussed open-air test sites.
