Jim,
we've tossed the "operator response" thing around here for many years. We've
tried to keep it as simple as possible.
For instance, if a printer stops and recognizes an image quality fault as a
result of an ESD or EFT test, and then the printer prompts the operator to
discard the faulted print
Criterion B is "Self-Recoverable" without user intervention which means it
must return to normal operation on its own after the test. BUT during the
test, your printer is allowed to degrade in performance such as print
incorrectly or stop printing or reset itself. After the test, the printer
must
Jim, my thoughts an issue like this is not to be concerned with trying to
interpret what the standard means but what will the customer put up with.
The customer after all is the ultimate "standard" that must be complied
with. If a customer has to do it once a year, it is not a big deal but 30
times

A lawyer could have a field day with this sort of thing (at considerable

You'll never make it on a standards committee. You don't use enough words

The standard is crystal-clear; it's real life that's grey and fuzzy.

Ralph,
If a product self-recovers without operator intervention, then you can say it
meets criterion B. The manufacturer has the ability within these criteria to
define the acceptable loss of function, as well. If 1 minute is an acceptable
time for the self-recovery, the product passes. If o

Yes Chris, this is exactly
what the criterium A is about. The manufacturer
should specify the performance of the product during
exposure to radiated (or conducted) RF-interference.
The device should of course not loose 100 % of it's performance though.
