How to measure capacitors/Test a Capacitors (8): How can I
3 · A. Insulation Resistance (IR) is the extent to which the dielectric material in a capacitor resists leakage current. It is the resistance of the dielectric material itself*1. IR is measured by leakage current. Knowing the leakage current and applied voltage, the insulation resistance can be calculated based on the ohm''s law.
Capacitor Leakage Experiments
All in all, it looks like an electrolytic capacitor that is operated at a fraction of its voltage rating, this one is rated at 25V, can have a surprisingly good leakage figure at room temperature. Conversely, it . also means that to do a sensible worst-case test of the leakage probably requires a bias adjustable up to . the rated voltage.

What is the "CV" unit for leakage current in a capacitor datasheet?
The actual leakage of an electrolytic cap may be much less than the rated value or a bit less. Chances are a higher voltage rated capacitor will have lower leakage when operated at a much lower than rated voltage, but it is not guaranteed, nor will it necessarily last if the capacitor is continuously operated at lower than rated voltage.. The …
