Thanks everyone for your thoughts. But in the case of ESD testing, IEC
61000-4-2 is not a very good standard. We knew this in 1996 where work done by
myself and others showed that the waveform needs to have a di/dt spec to rule
out the uncontrolled high frequency ringing many simulators
I suspect that folks who have been directly involved with air-discharge
ESD can appreciate it's inherent, operator influenced, uncertainly.
Having run both internal and third party EMC test labs, I recognize that
few things are done "perfectly" (whatever "perfect" is), but I've always
The basic question is, "How good is good enough?"
Risk standards for product safety address that question to some extent, but
it applies to every lab measurement, whether the applicable standards (or
regulations) consider it or not.

But crossing t's and dotting i's is exactly what is required by
competence standards, including the several ISO 170XX series.
Furthermore, standards specify performance of test equipment, if
possible, and only if that is not possible, they specify design. If that
is not possible, they specify
