Charles,

This is a contentious subject for us due to the time it takes to thoroughly
test a large product, so I'd be interested in hearing other's opinions and
practices.  

A scenario where ESD can cause a genuine problem (in our business) is when
someone walks across a room to add paper to a printer tray.  In some
machines, the unit will be in standby mode.  In others, it may continue
printing from a different tray or cabinet.  In either case, a discharge to
the internal metal parts of the paper tray could conceivably cause problems
we would consider failures (and have).

Subject: Question on internal ESD testing



Hello,

Does anyone in this august group apply ESD discharges INTERNAL
to a product as required by EN55024. 

I consider this just a tad egregious - don't you?

Thank you
