No, it is
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 quick

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
system.

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 allow

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
