is debugging for quality, but then, isnt the
purpose of compliance testing to 'test to fail' rather than test to pass?
I've been following this thread about ESD testing and the PPS debate.
I would like to inject my point of view on the subject.
So far most of what I have read addresses the need for speed.
This is great for the test lab/house; to be able to slam through the process
in a quest to get it done

This has come up everywhere I've worked. In order to adequately test for
vulnerability, logically, one has to apply a discharge during each of the

operating conditions an equipment might take. Given the number of different
logical states a microprocessor-controlled EUT might use, this could take
Greetings,
Let me add something to Joe's position (which I agree with entirely)
based upon my experience at a former job. Some products with no ground
or not so great grounds will need time (one sec or sometimes more)
between discharges to ensure that there is no build up of charge on the

Amund,
My experience has been that the labs would prefer to perform the ESD
tests at a rate of 1 pulse/second (pps) for the sake of efficiency. If the
product passes then it was completed in the least amount of time and
everyone's happy. If the product fails at 1 pps, then you are

Seems to me the time between discharges is the same as the time between
pulses (I believe that was the intent). I don't have the standard in front
of me, but I think the max rate was 1/second, which means you could go
slower. In most tests I've seen, the several discharges at one point are run
