Yes, 61000-4-2- is not very good, but while you are reluctant to share
your knowledge with the committee, it is unlikely that anything will happen.

Hi All,
I have a few thoughts I would like to share with you on ESD that have
comes out of my private research into the field in recent years.
1. A 2kV air discharge can be much more likely to cause equipment
malfunction than any other discharge of any voltage.
2. There is no natural ESD event comparable to a 15-20+ kV contact
discharge so why test for it? That is designing for something that
is extremely unlikely at best.
3. The IEC61000-4-2 does not very well model real ESD events at all.
One example, my hand metal discharge at 4 kV results a current
spike at the start of the discharge that is more than twice as
high as the standard specifies! This is very repeatable.
The above is just a sample of the research I have generated over the
years. Seems like IEC 61000-4-2 needs an urgent overhaul as I believe
engineers get a false sense of security that passing the test means
reliable field performance, not even close!
