6kV * 1.414 pk/rms = 8.5kV > 8kV..

It's overvoltaged by a bit, but there's probably some margin in the rating on the mica cap, at least voltage wise. OTOH, if you're looking at some kVAC RMS riding on top of a DC or line frequency offset, you could have twice that much. How much current were you passing through it?
