Or more specifically in terms of breakdown voltage. I participated on CE testing once, but unable to find internet info about the testing protocol being executed. These could be helpful?
If memory serves me right, one of the test consisted of applying High voltage High frequency AC voltage capacitive stressing of the primary to secondary dielectric for a fixed period of time.
P.S. I found these and these as a good start

You need to buy the standards (no, they are not freely available and they are copyrighted) from the agencies of the region(s) where they are applicable.
This can be costly if you need a world-wide coverage, because they are numerous, and not exactly cheap.
The general ideas behind the tests are the same everywhere, but the details can vary significantly.
With some ingenuity and determination, you can find partial or sometimes full copies here and there on the net
