So Barry asked if .001uA was correct.....

>0.001uA?  Is that correct?

So I repeated my test.. 10M VTVM in series with the disc cap and my bench supply set at 250VDC. VTVM shows 0.3V. Now 10v means 1uA leakage, 1 volt is 0.1uA, and 0.3V means .03uA leakage.

You are right, too many zeros. I got carried away............
It's .03uA leakage.

Sorry for the error
