Hi Gary,
Can you give us more details? If I remember correctly from my Bell Lab
days, the circuit pack ESD test I remember was useless as it assumed
boards were always held by the edges and zapped on a predetermined grid.
If the waveform is slower than IEC 61000-4-2 (801-2 was replaced by
this) the test is out of date and probably does not correlate to
whether the board will survive under real conditions. I would only do
this test for contract requirements (your case?).
Interesting coincidence, I am in Chandler, AZ USA for a meeting of IEC
TC77b (high frequency immunity) to rewrite the ESD (61000-4-2) and the
EFT (-4) specs. The new test will be quite different than the existing
one with the main benefit being more repeatable results.

Anybody know what equipment provides the waveform described above?
Its much slower than the IEC801 waveform. I tried Keytek and they
don't have it.
Other suggestions to perform the test - just use the IEC waveform?
