I understand the concerns and your reasoning, but if you define accessible
as anything I CAN touch, then it would inlcude all surfaces, connectors

There was considerable discussion in the Working Group regarding this issue

Mike,
I'm still not sold.
I understand the specific exemptions for circuit cards, battery compartments

You always need to apply two heads --- the engineering head says,Good
engineering practice says you should test for ESD, but the compliance head
only needs to meet

installed in PCs should be tested for ESD resistance in their bare state?

And there there are requirements one imposes on his own products, not those

I submit my opinion humbly
Agree with Don. May not be necessary but maintenance type ESD testing is a
very good idea. In fact part of the NEBS (Telecommunications test suite) has
circuit card ESD tests specifically for maintenance and production handling.
They do have a product ESD test but they are in different documents.

I think the local test lab is correct, since the product will be accessed
only for installation or maintenance. This is similar to the situation
where the covers are off a device for servicing - ESD testing is not
required for the internal circuitry of a device with the covers off.

Amund,
CISPR 24 (and EN 55024) provides reasons to not perform various tests, but ESD
doesn’t have any of these “outs”. I think you are entirely correct in
wanting the test done. Like you, I have seen this to be one of the more
applicable immunity tests (along with surge) and we test to
