Whatever amount of leakage current you decide would be acceptaable, it would 
be proportional to the capacitance.  A 2 mfd capacitor would be expected to 
have much lower leakage current than a 50 mfd one at the same voltage rating 
and test voltage.

For example, think of a 20 mfd cap as equivalent to ten 2-mfd caps wired in 
parallel.  So you would expect 10 times the leakage current with the 20 mfd.
